                          ANNUAL REPORT TO SHAREHOLDERS
                          REPORT OF INVESTMENT ADVISER

                                                              November 30, 1997

Dear Trust Shareholder:

      U.S.  fixed income  investors  have been rewarded with solid total returns
over the past twelve months, as moderate economic growth and low inflation drove
Treasury yields below year-end 1996 levels by October 31, 1997.

      The economy has shown some signs of slowing,  which BlackRock  expects may
persist as early  indicators  suggest that holiday  spending may be tepid. We do
not see  immediate  signs  of  inflationary  pressure  nor do we  anticipate  an
imminent change in monetary policy by the Federal Reserve. Our long-term outlook
for the bond market remains  optimistic,  based on the  fundamentally  favorable
backdrop  of slower  economic  growth,  low  inflation  and  declining  Treasury
borrowing.

      This report contains detailed market and portfolio strategy  commentary by
your Trust's  managers in addition to the Trust's audited  financial  statements
and a detailed portfolio listing. We thank you for your continued  investment in
the Trust and wish you a successful new year.

Sincerely,

/s/ Laurence D. Fink                                     /s/ Ralph L. Schlossein

                                                               November 30, 1997
Dear Shareholder:

      We are pleased to present  the annual  report for The  BlackRock  New York
Investment  Quality Municipal Trust Inc. ("the Trust") for the fiscal year ended
October 31, 1997. We would like to take this  opportunity  to review the Trust's
stock price and net asset value (NAV) performance, summarize market developments
and discuss recent portfolio management activity.

      The Trust is a  non-diversified,  actively  managed  closed-end  bond fund
whose shares are traded on the American  Stock  Exchange under the symbol "RNY".
The Trust's  investment  objective  is to provide  high  current  income that is
exempt from regular federal and New York state income taxes  consistent with the
preservation of capital.  The Trust seeks to achieve this objective by investing
in  investment  grade  (rated  "AAA"  to "BBB" by a major  rating  agency  or of
equivalent  quality)  municipal debt securities  issued by local  municipalities
throughout New York.

      The table below  summarizes the changes in the Trust's stock price and net
asset value over the year:

                        -------------------------------------------------------

STOCK PRICE                $14.25      $12.625     12.87%     $14.50     $12.25
- -------------------------------------------------------------------------------
NET ASSET VALUE (NAV)      $14.91      $14.00       6.50%     $14.91     $13.57
- -------------------------------------------------------------------------------

THE FIXED INCOME MARKETS

      The first half of the Trust's fiscal year was  characterized  by increased
concern over potential inflationary pressures.  Bond prices fell and yields rose
between  mid-December 1996 and mid-April 1997, as economic data indicated a very
strong  economy.  In an effort to subdue  this  growth and  pre-emptively  fight
inflation,  the Federal Reserve raised the Federal funds rate by 25 basis points
(1/4%)  to 5.50% at  their  March 25 FOMC  policy  meeting.  During  the  second
quarter,  however, signs of more moderate economic growth began to appear. Lower
factory orders, decreased consumer spending and higher inventories,  in addition
to continued benign inflationary forces,  soothed investor fears over inflation.
Accordingly,  the Federal Reserve left interest rates unchanged at their May 20,
July 2 and September 30 policy meetings. U.S. Treasury yields reflected investor
expectations of Federal Reserve policy  activity.  The yield of the 10-year note
rose from a period low of 6.04% in late November 1996 to 6.98% in mid-April 1997
in response to Federal Reserve  Chairman Alan  Greenspan's  warning of excessive
equity market euphoria and in anticipation of a Federal funds rate increase.  As
economic data softened, the yield of the 10-year fell over 100 basis points from
6.98% to close at 5.83% on October 31, 1997.

      The municipal bond market, represented by the LEHMAN MUNICIPAL BOND INDEX,
posted a total return of 8.50% for the 12 month  period ended  October 31, 1997,
underperforming  the domestic  taxable  investment grade market (measured by the
LEHMAN AGGREGATE INDEX), which returned 8.89%. Despite the rally in the Treasury
market,  demand for municipals was relatively  strong,  particularly  during the
summer,  when  nearly $60 billion  worth of  municipal  issues  matured and were
reinvested  back into the  market.  However,  the  decline  in  Treasury  yields
resulted in a significant increase in new municipal supply during September,  as
municipal issuers refunded higher interest bearing  securities and brought lower
yielding issues to market. During October,  municipals experienced their largest
underperformance versus Treasuries during 1997, as they were unable to keep pace
with the global demand for U.S. Treasuries.

      New York  State's  economy  remained  strong over the past twelve  months,
which is reflected in the State's fiscal year 1997-98 budget surplus,  which may
be as high as $1 billion. Wall Street's prosperity, fueled by the continued bull
market,  has resulted in increased tax revenues which have contributed  mightily
to the State's income growth. These increased revenues have mitigated the impact
of Governor Pataki's tax cuts; further tax reductions have been proposed to make
New York State more economically competitive.  The overall health of the State's
economy led Standard & Poor's to raise New York's  credit rating from A- to A in
September 1997.

THE TRUST'S PORTFOLIO AND INVESTMENT STRATEGY

      The Trust's portfolio is actively managed to diversify exposure to various
sectors,  issuers,  revenue sources and security types.  BlackRock's  investment
strategy  emphasizes  a  relative  value  approach,  which  allows  the Trust to
capitalize  upon  changing  market  conditions  by rotating  municipal  sectors,
credits and coupons.

      Additionally,  the Trust employs leverage at about 35% of total net assets
to enhance its income by borrowing at short term  municipal  rates and investing
the proceeds in longer maturity  issues which have higher yields.  The degree to
which the Trust can benefit  from its use of leverage  may affect its ability to
pay high  monthly  income.  Over the past twelve  months,  the  Federal  Reserve
tightened  monetary  policy by raising short term rates 25 basis points to 5.50%
in March.  Typically,  short term municipal  rates (which  determine the Trust's
borrowing  costs) are  approximately  65% of Treasury  rates.  Accordingly,  the
Trust's cost of leverage modestly increased as a result of the Fed's action.

     With respect to credit quality, the portfolio selectively took advantage of
yield spreads between  higher-rated (AA & AAA) and lower-rated (BBB- and A-) New
York municipal bonds where opportunities existed. The Trust will look to reverse
these trades when the  opportunities  present  themselves.  The Trust's  current
strategy  emphasizes high credit quality  non-callable and callable  premiums in
the 7- to 15-year maturity range.  Prevailing municipal market conditions do not
reward investors for extending beyond this maturity range.

THE BLACKROCK NEW YORK INVESTMENT
QUALITY MUNICIPAL TRUST INC.
NOTES TO FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------
NOTE 1. ACCOUNTING POLICIES  
The BlackRock New York Investment Quality Municipal Trust Inc. (the "Trust") was
organized  in  Maryland  on  April  12,  1993 as a  non-diversified,  closed-end
management  investment company. The Trust had no transactions until May 27, 1993
when it sold 7,093 shares of common  stock for  $100,012 to BlackRock  Financial
Management,  Inc., (the "Adviser").  Investment  operations commenced on June 4,
1993.

   The Trust's  investment  objective is to provide high current  income  exempt
from  regular  federal  and New  York  state  income  tax  consistent  with  the
preservation  of capital.  The ability of issuers of debt securities held by the
Trust to meet their obligations may be affected by economic  developments in the
state, a specific industry or region. No assurance can be given that the Trust's
investment objective will be achieved.

   The following is a summary of significant accounting policies followed by the
Trust.

SECURITIES VALUATION:  Municipal securities  (including  commitments to purchase
such  securities  on a  "when-issued"  basis)  are valued on the basis of prices
provided  by  a  pricing  service  which  uses   information   with  respect  to
transactions  in bonds,  quotations  from bond dealers,  market  transactions in
comparable   securities  and  various   relationships   between   securities  in
determining values. Any securities or other assets for which such current market
quotations  are not readily  available are valued at fair value as determined in
good faith under procedures established by and under the general supervision and
responsibility of the Trust's Board of Directors.

   Short-term securities which mature in more than 60 days are valued at current
market  quotations.  Short-term  securities  which mature in 60 days or less are
valued at amortized  cost, if their term to maturity from date of purchase is 60
days or less, or by amortizing their value on the 61st day prior to maturity, if
their  original  term to  maturity  from  date of  purchase  exceeded  60  days.
SECURITIES  TRANSACTIONS  AND INVESTMENT  INCOME:  Securities  transactions  are
recorded  on the trade  date.  Realized  and  unrealized  gains and  losses  are
calculated  on the  identified  cost basis.  Interest  income is recorded on the
accrual basis. The Trust accretes  original issue discounts or amortizes premium
on securities  purchased using the interest  method. 

FEDERAL INCOME TAXES: For federal income tax purposes, the Trust is treated as a
separate taxpaying entity. It is the intent of the Trust to continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to  distribute  all of its net income to  shareholders.  For this
reason and because  substantially  all of the Trust's  gross income  consists of
tax-exempt interest, no federal income tax provision is required.

DIVIDENDS  AND  DISTRIBUTIONS:   The  Trust  declares  and  pays  dividends  and
distributions to common  shareholders  monthly from net investment  income,  net
realized short-term capital gains and other sources, if necessary. Net long-term
capital  gains,  if any,  in excess  of loss  carryforwards  may be  distributed
annually.  Dividends and  distributions  are recorded on the  ex-dividend  date.
Dividends and distributions to preferred shareholders are accrued and determined
as described in Note 4.

DEFERRED  ORGANIZATION  EXPENSES:  A total of $19,000 was incurred in connection
with the organization of the Trust. These costs have been deferred and are being
amortized  ratably  over a period  of  sixty  months  from  the  date the  Trust
commenced investment operations.

RECLASSIFICATION  OF  CAPITAL  ACCOUNTS:  The Trust  accounts  and  reports  for
permanent differences between financial and tax reporting in accordance with the
American Institute of Certified Public Accountants'  Statement of Position 93-2:
Determination,  Disclosure  and  Financial  Statement  Presentation  of  Income,
Capital Gain and Return of Capital  Distributions by Investment  Companies.  The
effect of applying  this  statement  for the year ended  October 31, 1997 was to
increase accumulated net realized loss and increase undistributed net investment
income by $1,544.  Net investment income, net realized gains and net assets were
not affected by this change.

ESTIMATES:  The preparation of financial statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting  period.  Actual  results could differ from those  estimates. 

NOTE 2. AGREEMENTS 
The  Trust  has  an  Investment   Advisory  Agreement  with  BlackRock Financial
Management,  Inc., (The "Adviser"),  a wholly-owned  corporate subsidiary of PNC
Asset  Management  Group,  Inc., the holding company for PNC's asset  management
businesses and an  Administration  Agreement with  Prudential  Investments  Fund
Management, LLC ("PIFM"), an indirect, wholly-owned subsidiary of The Prudential
Insurance Company of America.

                                       11
<PAGE>

   The investment fee paid to the Adviser is computed weekly and payable monthly
at an annual rate of 0.35% of the Trust's average weekly net investment  assets.
The  administration fee paid to PIFM is also computed weekly and payable monthly
at an annual rate of 0.10% of the Trust's average weekly net investment assets.

   Pursuant to the agreements,  the Adviser provides  continuous  supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are affiliated persons of the Adviser.  PIFM pays occupancy and certain clerical
and accounting costs of the Trust. The Trust bears all other costs and expenses.

NOTE 3. PORTFOLIO SECURITIES
Purchases and sales of investment securities, other than short-term investments,
for the fiscal year ended October 31, 1997 aggregated $3,867,520 and $4,988,490,
respectively.

     The federal income tax basis of the Trust's investments at October 31, 1997
was  substantially   the  same  as  the  basis  for  financial   reporting  and,
accordingly, net and gross unrealized appreciation was $1,865,023.

   For federal income tax purposes, the Trust had a capital loss carryforward at
October 31, 1997 of approximately $647,000 of which $448,000 will expire in 2002
and $199,000  will expire in 2003.  Such  carryfoward  is after  utilization  of
appoximately  $125,000 to offset the Trust's net taxable gains recognized in the
year ended  October 31, 1997.  Accordingly,  no capital  gains  distribution  is
expected to be paid to shareholders until net gains have been realized in excess
of such amount.

NOTE 4. CAPITAL 
There are 200 million shares of $.01 par value common stock  authorized.  Of the
1,307,093  shares  outstanding  at October 31,  1997,  the  Adviser  owned 7,093
shares.  As of October 31, 1997 there were 392 shares of Preferred  Stock Series
F7 outstanding.

     Offering costs  ($111,638)  incurred in connection with the underwriting of
the Trust's  common stock have been charged to paid-in  capital in excess of par
of the common stock.

   The Trust may classify or reclassify any unissued shares of common stock into
one or more series of preferred  stock. On July 29, 1993 the Trust  reclassified
196 shares of common stock and issued a series of Auction Market Preferred Stock
("Preferred  Stock") Series F7. The Preferred  Stock had a liquidation  value of
$50,000 per share plus any  accumulated  but unpaid  dividends.  On May 16, 1995
shareholders approved a proposal to split each share of preferred stock into two
shares and  simultaneously  reduce  each  share's  liquidation  preference  from
$50,000 to $25,000 plus any  accumulated but unpaid  dividends.  The stock split
occurred on July 24, 1995.

   Underwriting  discounts  ($147,000) and offering costs ($76,063)  incurred in
connection  with the  Preferred  Stock  offering  have been  charged  to paid-in
capital in excess of par of the common stock.

   Dividends on Series F7 are  cumulative at a rate  established  at the initial
public  offering and are typically reset every 7 days based on the results of an
auction. Dividend rates ranged from 3.00% to 4.30% during the year ended October
31, 1997.

   The Trust may not declare dividends or make other  distributions on shares of
common  stock or purchase  any such  shares if, at the time of the  declaration,
distribution,  or  purchase,  asset  coverage  with  respect to the  outstanding
Preferred Stock would be less than 200%.

   The Preferred  Stock is redeemable at the option of the Trust, in whole or in
part, on any dividend  payment date at $25,000 per share plus any accumulated or
unpaid dividends whether or not declared. The Preferred Stock is also subject to
mandatory  redemption  at  $25,000  per  share  plus any  accumulated  or unpaid
dividends,  whether or not  declared  if certain  require-ments  relating to the
composition  of the  assets  and  liabilities  of the  Trust as set forth in the
Articles of Incorporation are not satisfied.

   The holders of  Preferred  Stock have voting  rights  equal to the holders of
common stock (one vote per share) and will vote  together with holders of shares
of common stock as a single class. However,  holders of Preferred Stock are also
entitled to elect two of the Trust's  directors.  In  addition,  the  Investment
Company Act of 1940 requires that along with approval by stockholders that might
otherwise  be  required,  the  approval  of the  holders  of a  majority  of any
outstanding  preferred shares, voting separately as a class would be required to
(a) adopt any plan of  reorganization  that would adversely affect the preferred
shares and (b) take any action requiring a vote of security holders,  including,
among other  things,  changes in the Trust's  subclassification  as a closed-end
investment company or changes in its fundamental investment restrictions.

NOTE 5. DIVIDENDS 
Subsequent to October 31, 1997,  the Board of Directors of the Trust  declared a
dividend  from  undistributed  earnings of  $.068125  per common  share  payable
November 28, 1997 to shareholders of record on November 14, 1997.

   For the period November 1, 1997 to November 30, 1997,  dividends  declared on
Preferred  Stock  totalled  $24,885 in aggregate for the  outstanding  Preferred
Stock.

         THE BLACKROCK NEW YORK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                         REPORT OF INDEPENDENT AUDITORS
- -------------------------------------------------------------------------------

The Shareholders and Board of Directors of
The BlackRock New York Investment Quality Municipal Trust Inc.:

      We have  audited the  accompanying  statement  of assets and  liabilities,
including the  portfolio of  investments,  of The BlackRock New York  Investment
Quality  Municipal Trust Inc. as of October 31, 1997 and the related  statements
of operations  for the year then ended and of changes in net  investment  assets
for each of the two years in the period then ended and the financial  highlights
for each of the four years in the period  then ended and for the period  June 4,
1993  (commencement  of  investment  operations)  to  October  31,  1993.  These
financial  statements  and financial  highlights are the  responsibility  of the
Trust's  management.  Our  responsibility  is to  express  an  opinion  on these
financial statements and financial highlights based on our audits.

      We conducted our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures included confirmation of securities owned at October
31, 1997, by correspondence  with the custodian and brokers;  where replies were
not received from brokers, we performed other auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

      In our opinion, such financial statements and financial highlights present
fairly, in all material  respects,  the financial  position of The BlackRock New
York  Investment  Quality  Municipal  Trust Inc.  at October 31,  1997,  and the
results of its  operations,  the  changes in its net  investment  assets and its
financial  highlights  for the  respective  stated  periods in  conformity  with
generally accepted accounting principles.

                                 TAX INFORMATION
- -------------------------------------------------------------------------------
      We are required by the Internal  Revenue Code to advise you within 60 days
of the Trust's  fiscal year end  (October 31, 1997) as to the federal tax status
of dividends you received during such fiscal year.The dividend paid December 31,
1996 to common  shareholders  of record on December 16, 1996 included $.0044 per
share of taxable  ordinary  income.  The  dividend  paid  December  30,  1996 to
preferred  shareholders  of record on December 27, 1996 included $4.92 per share

preferred shareholders consisted of federal tax-exempt interest.

- -------------------------------------------------------------------------------
                           DIVIDEND REINVESTMENT PLAN
- -------------------------------------------------------------------------------
      Pursuant  to  the  Trust's  Dividend   Reinvestment   Plan  (the  "Plan"),
shareholders will  automatically have all distributions of dividends and capital
gains  reinvested  by State Street Bank and Trust  Company (the "Plan Agent") in
Trust  shares  pursuant to the Plan  unless an election is made to receive  such
amounts in cash.  The Plan Agent will affect  purchases of shares under the Plan
in the open market.  Shareholders  who elect not to participate in the Plan will
receive all  distributions in cash paid by check in United States dollars mailed
directly to the  shareholders  of record (or if the shares are held in street or
other  nominee  name,  then to the nominee) by the transfer  agent,  as dividend
disbursing agent.

      The Plan Agent serves as agent for the shareholders in  administering  the
Plan.  After the Trust  declares a dividend or determines to make a capital gain
distribution,  the Plan Agent will, as agent for the  participants,  receive the
cash payment and use it to buy Trust shares in the open market,  on the American
Stock Exchange or elsewhere,  for the participants' accounts. The Trust will not
issue any new shares in connection with the Plan.

      Participants in the Plan may withdraw from the Plan upon written notice to
the Plan Agent and will receive  certificates  for whole Trust shares and a cash
payment for any fraction of a Trust share.

      The Plan Agent's fees for the  handling of the  reinvestment  of dividends
and distributions will be paid by the Trust.  However, each participant will pay
a pro rata share of  brokerage  commissions  incurred  with  respect to the Plan
Agent's open market  purchases in connection with the  reinvestment of dividends
and  distributions.  The automatic  reinvestment of dividends and  distributions
will not relieve  participants of any federal,  state or local income taxes that
may be payable on such dividends or distributions.

      Experience  under  the Plan  may  indicate  that  changes  are  desirable.
Accordingly,  the Trust  reserves  the right to amend or  terminate  the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
change sent to all  shareholders of the Trust at least 90 days before the record
date for the dividend or distribution.  The Plan also may be amended by the Plan
Agent upon at least 90 days' written  notice to all  shareholders  of the Trust.
The Plan may be  terminated by the Plan Agent or the Trust upon at least 30 days
written notice to all shareholders of the Trust. All  correspondence  concerning
the Plan should be directed to the Plan Agent at (800)  699-1BFM.  The addresses
are on the front of this report.

- -------------------------------------------------------------------------------
                             ADDITIONAL INFORMATION
- -------------------------------------------------------------------------------
      There have been no material changes in the Trust's  investment  objectives
or policies that have not been approved by the  shareholders,  or to its charter
or by-laws,  or in the principal risk factors  associated with investment in the
Trust.  There have been no changes in the persons who are primarily  responsible
for the day-to-day management of the Trust's portfolio.

         THE BLACKROCK NEW YORK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                               INVESTMENT SUMMARY
- -------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The BlackRock New York Investment Quality Municipal Trust's investment objective
is to provide high current  income exempt from regular  Federal,  State and City
income tax consistent with the preservation of capital.

WHO MANAGES THE TRUST?

BlackRock  Financial  Management,  Inc.  ("BlackRock"  or  the  Adviser)  is the
investment adviser for the Trust.  BlackRock is a registered  investment adviser
specializing in fixed income securities.  Currently,  BlackRock manages over $50
billion of assets  across the  government,  mortgage,  corporate  and  municipal
sectors.  These  assets are managed on behalf of  institutional  and  individual
investors in 21 closed-end funds traded on either the New York or American Stock
Exchanges,  several  open-end  funds and over 125 separate  accounts for various
clients  in the U.S.  and  overseas.  BlackRock  is a  subsidiary  of PNC  Asset
Management  Group which is a division  of PNC Bank,  N.A.,  one of the  nation's
largest banking organizations.

WHAT CAN THE TRUST INVEST IN?

Under normal  conditions,  the Trust expects to continue to manage its assets so
that at least 80% of its investments are rated at least  investment grade ("BBB"
by Standard & Poor's and "Baa" by Moody's  Investor  Services)  and up to 20% of
its  assets  may  instead be deemed to be of  equivalent  credit  quality by the
Adviser.  The Trust  intends  to  invest  substantially  all of the  assets in a
portfolio of investment grade New York Municipal Obligations, which include debt
obligations  issued by or on behalf of the  State,  its  political  subdivisions
(including the City),  agencies and  instrumentalities  and by other  qualifying
issuers  that pay  interest  which,  in the  opinion of the bond  counsel of the
issuer,  is exempt from  regular  Federal,  State and City income tax.  New York
Municipal Obligations may be issued to obtain funds for various public purposes,
including  the  construction  of such public  facilities  as airports,  bridges,
highways, housing,  hospitals, mass transportation,  schools, streets, water and
sewer works. Other public purposes for which New York Municipal  Obligations may
be issued include the  refinancing of outstanding  obligations and the obtaining
of  funds  for  general  operating  expenses  and  for  loans  to  other  public
institutions and facilities.

WHAT IS THE ADVISER'S INVESTMENT STRATEGY?

The Adviser will manage the assets of the Trust in  accordance  with the Trust's
investment  objective and policies to seek to achieve its objective by investing
in investment grade New York Municipal Obligations. The Adviser actively manages
the assets in relation to market conditions and interest rate changes. Depending
on yield and  portfolio  allocation  considerations,  the  Adviser may choose to
invest a portion of the Trust's assets in securities  which pay interest that is
subject  to AMT  (alternative  minimum  tax).  The Trust  intends  to  emphasize
investments in New York  Municipal  Obligations  with  long-term  maturities and
expects to  maintain  an average  portfolio  maturity  of 15-20  years,  but the
average  maturity may be shortened or lengthened  from time to time depending on
market conditions.

Under current market conditions the use of leverage  increases the income earned
by the Trust.  The Trust  employs  leverage  primarily  through the  issuance of
preferred  stock.   Preferred  stockholders  will  receive  dividends  based  on
short-term rates in exchange for allowing the Trust to borrow additional assets.
These assets will be invested in longer-term assets which typically offer higher
interest  rates and the  difference  between the cost of the  dividends  paid to
preferred  stockholders  and the interest earned on the  longer-term  securities
will provide higher income levels for common  stockholders in most interest rate
environments.  The Trust issued  preferred  stock to leverage  the  portfolio at
approximately  35% of total assets.  See "Leverage  Considerations in the Trust"
below.

HOW ARE THE TRUST'S SHARES PURCHASED AND SOLD? DOES THE TRUST PAY DIVIDENDS
REGULARLY?

The Trust's  shares are traded on the American  Stock  Exchange  which  provides
investors with  liquidity on a daily basis.  Orders to buy or sell shares of the
Trust must be placed through a registered broker or financial advisor. The Trust
pays monthly  dividends which are typically paid on the last business day of the
month. For shares held in the shareholder's name, dividends may be reinvested in
additional  shares of the fund through the Trust's transfer agent,  State Street
Bank and Trust Company. Investors who wish to hold shares in a brokerage account
should check with their financial  advisor to determine  whether their brokerage
firm offers dividend reinvestment services.


                                       15
<PAGE>

LEVERAGE CONSIDERATIONS IN THE TRUST

Leverage  increases  the duration (or price  sensitivity  of the net assets with
respect to changes  in  interest  rates) of the  Trust,  which can  improve  the
performance  of the Trust in a  declining  rate  environment,  but can cause net
assets to decline  faster in a rapidly  rising  interest rate  environment.  The
Trust may reduce,  or unwind,  the amount of leverage  employed should BlackRock
consider that  reduction to be in the best  interests of the Trust.  BlackRock's
portfolio managers  continuously monitor and regularly review the Trust's use of
leverage  and  maintain  the  ability to unwind the  leverage  if that course is
chosen.

SPECIAL CONSIDERATIONS AND RISK FACTORS RELEVANT TO THE TRUST

THE TRUST IS  INTENDED  TO BE A  LONG-TERM  INVESTMENT  AND IS NOT A  SHORT-TERM
TRADING VEHICLE.

INVESTMENT  OBJECTIVE.  Although  the  objective of the Trust is to provide high
current income exempt from regular Federal, State and City income tax consistent
with the preservation of capital,  there can be no assurance that this objective
will be achieved.

DIVIDEND  CONSIDERATIONS.  The income and dividends paid by the Trust are likely
to vary over time as fixed income market conditions change. Future dividends may
be higher or lower than the dividend the Trust is currently paying.

LEVERAGE.  The Trust utilizes leverage through  preferred stock,  which involves
special risks. The Trust's net asset value and market value may be more volatile
due to its use of leverage.

MARKET PRICE OF SHARES.  The shares of closed-end  investment  companies such as
the Trust trade on the American Stock  Exchange  (AMEX symbol:  RNY) and as such
are subject to supply and demand influences.  As a result, shares may trade at a
discount or a premium to their net asset value.

INVESTMENT GRADE MUNICIPAL  OBLIGATIONS.  The value of municipal debt securities
generally  varies  inversely with changes in prevailing  market  interest rates.
Depending  on the amount of call  protection  that the  securities  in the Trust
have, the Trust may be subject to certain  reinvestment risks in environments of
declining interest rates.

ILLIQUID  SECURITIES.  The Trust may  invest in  securities  that are  illiquid,
although  under current  market  conditions the Trust expects to do so to only a
limited extent. These securities involve special risks.

ANTITAKEOVER  PROVISIONS.  Certain antitakeover provisions will make a change in
the Trust's  business or management  more difficult  without the approval of the
Trust's Board of Directors and may have the effect of depriving  shareholders of
an  opportunity  to sell their shares at a premium above the  prevailing  market
price.

         THE BLACKROCK NEW YORK INVESTMENT QUALITY MUNICIPAL TRUST INC.
                                    GLOSSARY
- -------------------------------------------------------------------------------

CLOSED-END FUND:             Investment  vehicle which initially  offers a fixed
                             number of shares  and  trades on a stock  exchange.
                             The fund  invests in a portfolio of  securities  in
                             accordance  with its stated  investment  objectives
                             and policies.

DISCOUNT:                    When a fund's net asset  value is greater  than its
                             stock  price  the fund is said to be  trading  at a
                             discount.

DIVIDEND:                    Income  generated by  securities in a portfolio and
                             distributed to shareholders  after the deduction of
                             expenses. This Trust declares and pays dividends to
                             common shareholders on a monthly basis.

DIVIDEND REINVESTMENT:       Shareholders  may elect to have all  dividends  and
                             distributions   of  capital   gains   automatically
                             reinvested into additional shares of the Trust.

MARKET PRICE:                Price  per  share  of a  security  trading  in  the
                             secondary  market.  For a closed-end  fund, this is
                             the price at which one share of the fund  trades on
                             the  stock  exchange.  If you  were  to buy or sell
                             shares, you would pay or receive the market price.

NET ASSET VALUE (NAV):       Net asset  value is the total  market  value of all
                             securities and other assets held by the Trust, plus
                             income  accrued  on  its  investments,   minus  any
                             liabilities including accrued expenses,  divided by
                             the total number of outstanding  shares.  It is the
                             underlying  value of a single share on a given day.
                             Net asset value for the Trust is calculated  weekly
                             and  published  in BARRON'S on Saturday and THE NEW
                             YORK TIMES or THE WALL STREET JOURNAL each Monday.

PREMIUM:                     When a fund's  stock price is greater  than its net
                             asset  value,  the fund is said to be  trading at a
                             premium.

PREREFUNDED BONDS:           These   securities  are   collateralized   by  U.S.
                             Government  securities which are held in escrow and
                             are used to pay  principal  and interest on the tax
                             exempt  issue  and  retire  the bond in full at the
                             date indicated, typically at a premium to par.

                      BLACKROCK FINANCIAL MANAGEMENT, INC.
                                   AN OVERVIEW
- -------------------------------------------------------------------------------

      BlackRock  Financial  Management  (BlackRock)  is a registered  investment
adviser which specializes in managing high quality fixed income securities, both
taxable and tax exempt.  BlackRock  currently manages over $50 billion of assets
across the government,  mortgage,  corporate and municipal sectors. These assets
are managed on behalf of many  individual  investors  in  twenty-one  closed-end
funds  traded on either the New York or American  stock  exchanges,  and several
open-end  funds  and on behalf of more  than 125  institutional  clients  in the
United States and overseas.

      BlackRock  was  formed in April  1988 by fixed  income  professionals  who
sought to create an asset management firm  specializing in managing fixed income
securities for individuals and  institutional  investors.  The  professionals at
BlackRock have extensive experience creating, analyzing and trading a variety of
fixed income instruments,  including the most complex structured securities.  In
fact, individuals at BlackRock are responsible for many of the major innovations
in the  mortgage-backed  and  asset-backed  securities  markets,  including  the
creation of the CMO, the floating rate CMO, the senior/subordinated pass-through
and the multi-class asset-backed security.

      BlackRock  is unique  among asset  management  and  advisory  firms in the
significant  emphasis it places on the  development  of  proprietary  analytical
capabilities.  A quarter of the professionals at BlackRock work full-time in the
design,  maintenance  and use of such systems  which are otherwise not generally
available to investors.  BlackRock's  proprietary  analytical tools are used for
evaluating,  investing in and designing investment  strategies and portfolios of
fixed  income  securities,   including  mortgage   securities,   corporate  debt
securities or tax-exempt securities and a variety of hedging instruments.

      BlackRock has developed  investment  products  which respond to investors'
needs and has been  responsible  for several  major  innovations  in  closed-end
funds.  BlackRock  introduced  the first  closed-end  mortgage  fund,  the first
taxable  and  tax-exempt  closed-end  funds to offer a finite  term,  the  first
closed-end  fund to achieve a AAAf  rating by  Standard & Poor's,  and the first
closed-end  fund to invest  primarily in North American  Government  securities.
BlackRock's  closed-end funds currently have dividend  reinvestment  plans which
are  designed  to  provide  an  ongoing  source of  demand  for the stock in the
secondary market. BlackRock manages a ladder of alternative investment vehicles,
with each fund having specific investment objectives and policies.

      In view of our continued  desire to provide a high level of service to all
our shareholders, BlackRock maintains a toll-free number for your questions. The
number is (800) 227-7BFM (7236).  We encourage you to call us with any questions
you may have about your  BlackRock  funds and thank you for the continued  trust
you place in our abilities.
