Dear Shareholder,
I am  pleased  to  present  the Annual  Report  for the  National  Portfolio  of
Thornburg Limited Term Municipal Fund for the year ending June 30, 1998. The net
asset  value of the A shares  increased  6 cents per share to $13.50  during the
year. If you were with us for the entire period,  you received dividends of 60.7
cents per share.  If you reinvested  your  dividends,  you received 62 cents per
share.  Investors who owned C Shares  received  dividends of 55.3 and 56.3 cents
per share,  respectively.  Your Limited Term Municipal Fund portfolio  currently
holds over 500  municipal  obligations  from 49 states  and 2 U.S.  Territories.
Approximately  89% of the bonds are rated A or better by one of the major rating
agencies. As you know, we "ladder" the maturities of the bonds in your portfolio
so that some  bonds are  scheduled  to mature at par  during  each of the coming
years.  Today, your fund's weighted average maturity is approximately 4.0 years,
and we always keep it below 5 years.  Percentages  of the portfolio  maturing in
the coming years are  summarized  below:  % of  portfolio  Cumulative % maturing
within maturing by end of
            1 years = 10%           year 1 = 10%            
       1 to 2 years = 16%           year 2 = 26%
       2 to 3 years = 17%           year 3 = 43%
       3 to 4 years = 16%           year 4 = 59%
       4 to 5 years = 9%            year 5 = 68% 
       5 to 6 years = 10%           year 6 = 78%
       6 to 7 years = 7%            year 7 = 85%
       7 to 8 years = 6%            year 8 = 91%
       8 to 9 years = 5%            year 9 = 96%
     9 to 10  years = 4%           year 10 = 100%
Over the last year your average portfolio  maturity has increased
slightly.  The passage of time shortened the maturities of the bonds we owned at
the  beginning of the year. We directed  portfolio  cash flow and new money into
the five to nine year maturity  range of your bond ladder,  taking  advantage of
the plentiful  supply and good selection of new municipal bonds coming to market
this year.  Today we are  managing the  portfolio  to keep the average  maturity
approximately  where it is. We will stick with this  approach if interest  rates
remain stable or decrease.  If bond yields  increase,  we will likely extend the
average portfolio maturity. This would permit us to increase our dividend yields
if higher yields are  available.  For the past 4 years  Americans  have been net
sellers of  municipal  and  government  bonds.  Investment  dollars  have flowed
instead to equities,  money market  investments,  and (until recently)  overseas
opportunities. A combination of sharp volatility in equity markets worldwide and
deflationary  winds  blowing  from Asia may be  rekindling  the appetite of U.S.
investors for bond  investing,  although the money flows are not yet significant
from domestic  investors.  If the Federal Reserve cuts short term interest rates
in the coming months to shape up the U.S. economy and limit dollar appreciation,
some of the money  now  flowing  into  money  market  funds may begin to move to
intermediate and longer maturity bonds.  Assets of these money market funds* now
total over $1.2 trillion!  As the accompanying  graph shows,  long term interest
rates have fallen  considerably  in the last year in anticipation of an economic
slowdown and an expected drop in short term interest rates.


I believe any  observer  must be impressed  by the  fundamental  strength of the
broad U.S.  economy.  More people than ever before are working.  Wages are firm.
Tax receipts are off the charts, and government spending is accelerating.  There
will always be dislocations  here and there, but for the most part Americans are
very,  very busy.  The strong U.S.  economy  continues to be good for  municipal
America.  Taken as a whole,  U.S.  cities  continue to increase their  financial
reserves for the fifth  consecutive  year. Most states report similar  favorable
news,  and both  operating and capital budget  spending  levels are  increasing.
There is one  possible  cloud:  if the U.S.  economy  slows as state  and  local
government  spending  accelerates,  some entities will not manage the transition
smoothly.  If the current strength of the U.S. economy persists,  we expect long
maturity  interest  rates to increase in late 1998 or early 1999. If our economy
slows,  short  maturity bond rates and money market  interest rates will quickly
drop.  Over the years,  our  practices of laddering a  diversified  portfolio of
short and  intermediate  maturity  bonds has allowed  your fund to  consistently
perform  well in  varying  interest  rate  environments.  Your  fund has  earned
Morningstar's 4 star overall rating* for risk adjusted performance. I would like
to attribute this to capable  execution of a sensible  investment  strategy over
time.  Thank  you for  investing  in  Thornburg  Limited  Term  Municipal  Fund.
Sincerely,

Brian J. McMahon                                     
Portfolio Manager

Notes to financial statements


Note 1 - Organization
Thornburg  Limited Term Municipal  Fund,  Inc. (the "Fund") was  incorporated in
Maryland on February  14,  1984.  The Fund was  reorganized  in 1986 as a series
investment company with separate investment  portfolios.  The current portfolios
are as follows:  National Portfolio (the "Portfolio") and California  Portfolio.
The Fund is an open-end diversified  management  investment company,  registered
under the  Investment  Company Act of 1940, as amended.  The primary  investment
objective of the Fund is to obtain as high a level of current income exempt from
federal income tax as is consistent with preservation of capital.  The Portfolio
currently offers three classes of shares of beneficial interest,  Class A, Class
C and  Institutional  Class  (Class  I)  shares.  Each  class of  shares  of the
Portfolio  represents an interest in the same portfolio of  investments,  except
that (i) Class A shares are sold subject to a front-end  sales charge  collected
at the time the shares are purchased and bear a service fee, (ii) Class C shares
are sold at net asset value without a sales charge at the time of purchase,  but
are subject to a contingent  deferred  sales charge upon  redemption  within one
year, and bear both a service fee and a  distribution  fee, (iii) Class I shares
are sold at net asset value without a sales charge at the time of purchase,  and
(iv)  the   respective   classes   have   different   reinvestment   privileges.
Additionally,  the Portfolio may allocate among its classes certain expenses, to
the extent  allowable  to  specific  classes,  including  transfer  agent  fees,
government   registration   fees,   certain  printing  and  postage  costs,  and
administrative  and legal expenses.  Currently,  class specific  expenses of the
Portfolio are limited to  distribution  fees,  administrative  fees, and certain
transfer agent expenses.

Note 2 - Significant  Accounting Policies Significant accounting policies of the
Fund are as follows:
Valuation of  Investments:  In determining the net asset value of the Portfolio,
the Fund  utilizes  an  independent  pricing  service  approved  by the Board of
Directors. Debt investment securities have a primary market over the counter and
are valued on the basis of  valuations  furnished  by the pricing  service.  The
pricing  service values  portfolio  securities at quoted bid prices or the yield
equivalents  when  quotations  are not readily  available.  Securities for which
quotations  are not readily  available are valued at fair value as determined by
the pricing  service  using methods  which  include  consideration  of yields or
prices of municipal  obligations of comparable quality,  type of issue,  coupon,
maturity and rating;  indications  as to value from  dealers and general  market
conditions.  The  valuation  procedures  used  by the  pricing  service  and the
portfolio  valuations  received by the Portfolio are reviewed by the officers of
the Fund under the general  supervision  of the Board of  Directors.  Short-term
obligations  having  remaining  maturities  of 60  days or less  are  valued  at
amortized cost, which approximates value. Federal Income Taxes: It is the policy
of the  Fund  to  comply  with  the  provisions  of the  Internal  Revenue  Code
applicable  to "regulated  investment  companies"  and to distribute  all of its
taxable  (if any) and tax  exempt  income  to its  shareholders.  Therefore,  no
provision for Federal  income tax is required.  Dividends  paid by the Portfolio
for the year ended June 30, 1998 represent  exempt interest  dividends which are
excludable by  shareholders  from gross income for Federal  income tax purposes.
When-Issued  and  Delayed  Delivery   Transactions:   The  Fund  may  engage  in
when-issued or delayed delivery transactions.  To the extent the Fund engages in
such  transactions,  it  will  do so for  the  purpose  of  acquiring  portfolio
securities  consistent  with the investment  objectives of the Portfolio and not
for the purpose of investment leverage or to speculate on interest rate changes.
At the  time  the  Fund  makes a  commitment  to  purchase  a  security  for the
Portfolio, on a when-issued basis, the Portfolio will record the transaction and
reflect  the value in  determining  its net asset  value.  When  effecting  such
transactions,  assets of the  Portfolio of an amount  sufficient to make payment
for  the  portfolio  securities  to be  purchased  will  be  segregated  on  the
Portfolio's records on the trade date.  Securities purchased on a when-issued or
delayed  delivery  basis  do  not  earn  interest  until  the  settlement  date.
Dividends:  Net  investment  income  of the  Portfolio  is  declared  daily as a
dividend on shares for which the Fund has received  payment.  Dividends are paid
monthly and are  reinvested in  additional  shares of the Portfolio at net asset
value per share at the close of business on the dividend payment date, or at the
shareholder's  option, paid in cash. Net capital gains, to the extent available,
will be distributed annually. General: Securities transactions are accounted for
on a trade date  basis.  Interest  income is accrued  as  earned.  Premiums  and
original issue discounts on securities  purchased are amortized to call dates or
maturity dates of the respective securities.  Realized gains and losses from the
sale of securities are recorded on an identified  cost basis.  Use of 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 increases and  decreases in net assets from  operations
during the reporting period. Actual results could differ from those estimates.

Note 3 - Merger of MacKenzie National Municipal Fund
On September 4, 1997,  the Fund  acquired all of the net assets of the MacKenzie
Limited  Term  National  Municipal  Fund  ("MacKenzie")  pursuant  to a plan  of
reorganization approved by MacKenzie's shareholders. The merger was accomplished
by a  tax  free  exchange  of  Class  A  shares  of  the  Portfolio  (valued  at
$51,645,133)  for the net  assets of  MacKenzie  which  aggregated  $51,645,133,
including $1,028,723 of unrealized appreciation.  The combined net assets of the
Portfolio immediately after merger were $936,759,616.

Note 4 - Investment Advisory Fee and Other Transactions With Affiliates
Pursuant to an investment advisory agreement, Thornburg Management Company, Inc.
(the "Adviser") serves as the investment adviser and performs services for which
