            THE BLACKROCK FLORIDA INVESTMENT QUALITY MUNICIPAL TRUST
                      SEMI-ANNUAL REPORT TO SHAREHOLDERS

                                                                    May 31, 2000


Dear Shareholder:

     The  Federal  Reserve  continued  to  aggressively tighten in an attempt to
achieve  its  objective  of  a soft-landing for the explosive U.S. economy. As a
result,  the  Federal  Reserve  tightened  short-term  rates by 0.75% during the
period  and  raised  rates by another 0.50% at the May FOMC meeting to 6.50%. In
the   first  four  months  of  the  new  millennium  we  have  been  witness  to
unprecedented  volatility  in  both  the  Treasury  yield  curve  and the spread
sectors.  The  Treasury  curve inverted sharply as expectations of continued Fed
tightening  in  the  wake of an insatiable U.S. economy, while anticipation of a
significant  buyback  at  the  long  end  of  the maturity spectrum led to lower
yields  on  long  Treasuries.  The  yield curve inversion along with the premium
placed   on   the   dwindling   outstanding   Treasuries   caused   a   dramatic
underperformance  of  spread sectors relative to the performance of the Treasury
sectors, especially in the 10- to 30-year part of the curve.

     At  this  juncture, the general implication for spread product is negative,
but  the  potential  for  spread widening is more limited. Most of the negatives
for  high  quality  spread  product  in  terms  of relative supply differentials
between  Treasuries  and non-Treasuries as well as equity market volatility have
been  priced  into  the  market.  Given current market conditions, we maintain a
significant  overweight  in  high  quality  spread product. Treasuries are fully
valued  even  considering  the  strong technicals in the market. While near-term
volatility  is  virtually  guaranteed by an active Federal Reserve, a successful
soft  landing  of  the  economy  would  ultimately  result  in  a healthier U.S.
economy.

     This  report contains a summary of market conditions during the semi-annual
period  and  a review of portfolio strategy by your Trust's managers in addition
to  the  Trust's  unaudited  financial  statements  and  a  detailed list of the
portfolio's  holdings.  Continued  thanks  for  your confidence in BlackRock. We
appreciate  the opportunity to help you achieve your long-term investment goals.

Dear Shareholder:

     We are  pleased  to  present  the  unaudited  semi-annual  report  for  The
BlackRock Florida  Investment  Quality Municipal Trust ("the Trust") for the six
months ended April 30, 2000.  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 "RFA".  The
Trust's  investment  objective is to provide high current  income that is exempt
from both regular federal income tax and Florida  intangible  personal  property
tax 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 Florida.

     The table below  summarizes the  performance of the Trust's stock price and
NAV over the past six months:

--------------------------------------------------------------------------------
 NET ASSET VALUE (NAV)   $14.24       $14.29      (0.35%)   $14.50      $13.98
--------------------------------------------------------------------------------

THE FIXED INCOME MARKETS

     The dynamic  expansion of the U.S. economy  continues  undaunted by Federal
Reserve Chairman Greenspan's attempt to brake the economy,  short of stalling it
into a recession. The labor markets remain tight, growth remains strong with 5%+
annualized  growth  rates  and  inflation  pressures  continue  to be  offset by
increased  productivity.  However,  the Fed remains cautious,  in their February
minutes it was noted that: "Other members  acknowledged that the Committee might
need to move more aggressively at a later meeting should imbalances  continue to
build and  inflation  expectations  clearly  begin to pick  up." At the  Federal
Reserve meeting in November, February and March the Fed raised the discount rate
by 0.25%  at each  meeting  and a 0.50%  increase  was made in May to bring  the
current discount rate to 6.50%.

     The Treasury Yield curve  experienced a complex set of dynamics,  which has
inverted  the curve and may  continue  to invert  the curve for the  foreseeable
future.  The yields on the short-end of the curve  increased  sharply during the
period in response to three Federal  Reserve  increases to the discount rate and
perceived future Fed actions in the coming months.  The long-end of the curve is
reacting to the  "official"  announcement  that the  Treasury  will buy back $30
billion of Treasuries with maturities  ranging 10 to 30 years. With a decreasing
supply of available  Treasuries,  a balanced budget, and an unchanged demand for
longer maturity Treasuries, we would anticipate this condition to continue. This
condition is further augmented by Treasury auction activity,  as they reduce the
available  bonds on the long end of the curve they continue to add supply in the
1-10 year range through periodic auctions. For the semi-annual period, the yield
of the 10-year Treasury security rose from 6.02% on October 31, 1999 to 6.22% on
April 30, 2000.

     Municipal bonds  outperformed  the taxable  domestic bond market during the
past six months,  returning  2.63% (as measured by the LEHMAN  MUNICIPAL  INDEX)
versus the LEHMAN AGGREGATE INDEX'S 1.42% on a pre-tax basis.  Overall, the tone
in the  market  during  the  period  was  extremely  positive  as the  result of
continued strong demand from individual/retail investors coupled with a slowdown
in new issuance.  During 1999, households increased their holdings of individual
municipal  bonds  by over $40  billion  while  mutual  funds  saw net  outflows.
Offsetting the large amount of mutual fund outflows  during the first quarter of
2000 was a 43% decline in overall new municipal  bond issuance led by a 90% drop
in refunding  volume.  Refunding  volume was down due to the  relatively  higher
interest rates experienced during the first quarter 2000 when compared to the

                                       2

first  quarter  1999,  while  new money issuance has declined because the strong
economy  has  led  to  full coffers at most municipalities. Currently, municipal
bonds  across  the  entire  maturity  spectrum  are  at  their  most  attractive
relationships to their Treasury market counterparts.

     The State of  Florida's  strong  and  stable  financial  position  reflects
prudent financial management combined with a solid and diversifying economy. The
FY 1999  unreserved  General Fund balance was $3.5 billion or 20.5% of revenues;
this  provides  strong  bondholder  security.  FY 2000  revenues  are 2.1% above
budget,  to date,  enabling the State to project another year-end  surplus.  The
State's  policy is to maintain a moderate  debt burden while  continuing  to use
bonds to meet capital needs.

     In the last decade  Florida's  population  increased 20% (versus 8% for the
nation) to over 15 million  residents.  Although  economists  anticipate  slower
growth in the millennium, the population expansion is expected to exceed that of
the nation.  Unemployment  is expected to average 3.9% in 2000, the same as last
year.  Trade and services are the major employment  sectors while  manufacturing
jobs account for only 7.5% of Florida's  employment,  approximately one half the
national proportion. The construction industry has declined in importance as the
State's  economy  diversifies.  Florida's  stable  economy  combined  with rapid
population growth continues to fuel one of the country's strongest job markets.

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 to enhance its income by borrowing
at short-term  municipal  rates and  investing  the proceeds in longer  maturity
issues that 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.  At the
end of the  semi-annual  period,  the Trust's  leverage  amount was 34% of total
assets.

     As municipal credit spreads remained tight during the reporting  period, we
continued to emphasize  higher rated  securities over the lower rated investment
grade  sector.  We believe that credit  spreads  will return to more  historical
levels in the near  future  and as such the Trust  should  be  rewarded  for its
higher  credit  quality bias.  The Trust has continued its bias towards  premium
coupon  securities  over discount  priced  securities,  as premium coupons offer
better price  performance  during  periods of rising  interest rates and similar
performance to discounts when interest rates fall.

composition and credit quality allocations:

THE BLACKROCK FLORIDA INVESTMENT
QUALITY MUNICIPAL TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
--------------------------------------------------------------------------------

NOTE 1. ORGANIZATION & ACCOUNTING POLICIES

The  BlackRock  Florida  Investment  Quality  Municipal  Trust (the "Trust") was
organized in  Massachusetts  on April 15, 1993 as a  non-diversified  closed-end
management  investment company.  The Trust's investment objective is to manage a
portfolio of investment  quality  securities while providing high current income
exempt from regular federal income tax and Florida intangible  personal property
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  dealers or  pricing  services  approved  by the  Trust's  Board of
Trustees.  In determining the value of a particular  security,  pricing services
may use certain  information  with respect to transactions  in such  securities,
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
Trustees.

    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.  Short-term  securities with a term to maturity  greater than 60 days from
the date of purchase are valued at current market  quotations  until maturity or
disposition.

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 and the Trust  accretes  original  issue  discount  or  amortizes
premium on securities purchased using the interest method.

FEDERAL  INCOME  TAXES:  It is the  Trust's  intention  to  continue to meet the
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies  and to distribute  sufficient  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.

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.

DEFERRED  COMPENSATION PLAN: Under a deferred  compensation plan approved by the
Board of Trustees on February  24,  2000,  non-interested  Trustees may elect to
defer receipt of all or a portion of their annual compensation.

    Deferred amounts earn a return as though  equivalent dollar amounts had been
invested in common  shares of other  BlackRock  funds  selected by the Trustees.
This has the same  economic  effect as if the Trustees had invested the deferred
amounts in such other BlackRock funds.

    The  deferred  compensation  plan is not funded and  obligations  thereunder
represent  general unsecured claims against the general assets of the Trust. The
Trust may, however,  elect to invest in common shares of those funds selected by
the Trustees in order to match its deferred compensation obligations.


NOTE  2.  AGREEMENTS

The Trust has an Investment  Advisory  Agreement with BlackRock  Advisors,  Inc.
(the "Advisor"), which is a wholly-owned subsidiary of BlackRock, Inc., which in
turn is an indirect  majority-owned  subsidiary of PNC Financial Services Group,
Inc. The Trust has an Administration  Agreement with Prudential Investments Fund
Management LLC ("PIFM"),  a wholly-owned  subsidiary of The Prudential Insurance
Company of America.

                                       10
<PAGE>


    The  investment  advisory  fee paid to the  Advisor 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 Advisor provides continuous  supervision of
the investment  portfolio and pays the compensation of officers of the Trust who
are affiliated persons of the Advisor.  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 six months ended April 30, 2000 aggregated $0 and $40,000, respectively.

    The federal  income tax basis of the Trust's  investments  at April 30, 2000
was substantially the same as for financial reporting purposes and, accordingly,
net and gross unrealized appreciation was $986,940.

    For federal income tax purposes,  the Trust had a capital loss  carryforward
at  October  31,  1999 of  approximately  $699,000  which  will  expire in 2002.
Accordingly, no capital gain 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  of  beneficial  interest
authorized.  The  Trust  may  classify  or  reclassify  any  unissued  shares of
beneficial  interest  into  one or  more  series  of  preferred  shares.  Of the
1,127,093  common shares  outstanding at April 30, 2000, the Advisor owned 7,093
shares.  As of April 30, 2000 there were 340 shares of Preferred Stock Series R7
("Preferred Shares") outstanding.

    Dividends on Preferred  Shares are cumulative at a rate which is reset every
7 days based on the results of an auction.  Dividend  rates ranged from 3.40% to
5.00% during the six months ended April 30, 2000.

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

    The Preferred  Shares are 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  Shares are also
subject to mandatory  redemption  at $25,000 per share plus any  accumulated  or
unpaid dividends,  whether or not declared if certain  requirements  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  Shares have voting  rights equal to the holders of
common shares (one vote per share) and will vote together with holders of common
shares as a single class. However, holders of Preferred Shares are also entitled
to elect two of the Trustees.  In addition,  the Investment  Company Act of 1940
requires  that along with  approval  by  shareholders  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 restriction.

NOTE 5. DIVIDENDS

Subsequent   to  April  30,  2000,   the  Trustees   declared  a  dividend  from
undistributed  earnings  of 0.0663  per  common  share  payable  June 1, 2000 to
shareholders of record on May 15, 2000.

    For the period May 1, 2000 to May 31, 2000  dividends  declared on Preferred
Shares totaled $34,720 in aggregate for the outstanding Preferred Shares.

           THE BLACKROCK FLORIDA INVESTMENT QUALITY MUNICIPAL TRUST
                           DIVIDEND REINVESTMENT PLAN
--------------------------------------------------------------------------------

    Pursuant  to  the  Trust's   Dividend   Reinvestment   Plan  (the   "Plan"),
shareholders are  automatically  enrolled to 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.  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 under 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.

    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 or terminated by
the Plan Agent upon at least 90 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 address is on the front of this report.

           THE BLACKROCK FLORIDA INVESTMENT QUALITY MUNICIPAL TRUST
                              INVESTMENT SUMMARY
--------------------------------------------------------------------------------

THE TRUST'S INVESTMENT OBJECTIVE

The  BlackRock Florida Investment Quality Municipal Trust's investment objective
is  to provide high current income exempt from regular federal income tax and to
provide  an exemption from Florida intangible personal property taxes consistent
with the preservation of capital.

WHO MANAGES THE TRUST?

BlackRock  Advisors,  Inc.  (the  "Advisor")  is  an  SEC-registered  investment
advisor.  As  of  March  31,  2000,  the  Advisor  and its affiliates (together,
"BlackRock")  managed  $173  billion on behalf of taxable and tax-exempt clients
worldwide.  Strategies include fixed income, equity and cash and may incorporate
both  domestic  and  international  securities. Domestic fixed income strategies
utilize   the  government,  mortgage,  corporate  and  municipal  bond  sectors.
BlackRock  manages twenty-two closed-end funds that are traded on either the New
York  or  American  stock exchanges, and a $29 billion family of open-end funds.
BlackRock  manages  over  590  accounts,  domiciled  in  the  United  States and
overseas.

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  or "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
Advisor.  The  Trust  intends  to  invest  substantially  all of the assets in a
portfolio  of investment grade Florida Municipal Obligations, which include debt
obligations  issued  by  the  State  of  Florida,  its  political  subdivisions,
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  federal  income  tax.  Florida  Municipal Obligations are issued to obtain
funds  for  various  public  functions,  including  the  construction  of public
facilities,  the  refinancing of outstanding obligations, the obtaining of funds
for  general  operating  expenses and for loans to other public institutions and
facilities.

WHAT IS THE ADVISOR'S INVESTMENT STRATEGY?

The  Advisor  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 Florida Municipal Obligations or other qualifying issuers.
The  Advisor  actively  manages  the assets in relation to market conditions and
interest   rate   changes.   Depending   on   yield   and  portfolio  allocation
considerations,  the  Advisor  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 Florida 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  shareholders  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. 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 first 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.

                                       14

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 the Advisor
consider  that reduction to be in the best interests of the Trust. The Advisor'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  income  tax  and  to provide an
exemption  from  Florida  intangible personal property taxes 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 the issuance of 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: RFA) 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
Trustees  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 FLORIDA INVESTMENT QUALITY MUNICIPAL TRUST
                                   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 have all dividends and  distributions
                         of  capital   gains   automatically   reinvested   into
                         additional shares of a fund.

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 WALL STREET
                         JOURNAL on 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 ADVISORS, INC.
                                  AN OVERVIEW
--------------------------------------------------------------------------------

    BlackRock  Advisors,  Inc. (the "Advisor") is an  SEC-registered  investment
advisor.  As of March  31,  2000,  the  Advisor  and its  affiliates  (together,
"BlackRock")  managed $173 billion on behalf of taxable and  tax-exempt  clients
worldwide.  Strategies include fixed income, equity and cash and may incorporate
both  domestic and  international  securities.  BlackRock  manages  twenty-three
closed-end  funds  that are  traded on  either  the New York or  American  stock
exchanges,  and a $29 billion family of open-end funds.  BlackRock  manages over
590 accounts, domiciled in the United States and overseas.

    BlackRock's  fixed income product was introduced in 1988 by a team of highly
seasoned  fixed  income   professionals.   These   professionals  had  extensive
experience   creating,   analyzing   and  trading  a  variety  of  fixed  income
instruments,  including the most complex structured securities. In fact, several
individuals  at BlackRock  were  responsible  for  developing  many of the major
innovations  in  the  mortgage-backed   and  asset-backed   securities  markets,
including   the  creation  of  the  first  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
emphasis it places on the  development of proprietary  analytical  capabilities.
Over one  quarter of the  firm's  professionals  are  dedicated  to the  design,
maintenance  and use of these  systems,  which are not  otherwise  available  to
investors. BlackRock's proprietary analytical tools are used for evaluating, and
designing fixed income investment  strategies for client portfolios.  Securities
purchased include mortgages,  corporate bonds,  municipal bonds and a variety of
hedging instruments.

    BlackRock has developed investment products that respond to investors' needs
and has been responsible for several major  innovations in closed-end  funds. In
fact, 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 AAA rating by Standard & Poor's, and the first closed-end fund
to  invest  primarily  in  North  American  Government  securities.   Currently,
BlackRock's  closed-end  funds  have  dividend  reinvestment  plans,  which  are
designed  to  provide  ongoing  demand  for the stock in the  secondary  market.
BlackRock  manages a wide range of  investment  vehicles,  each 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
