Dear Fellow Shareholder:

I am pleased to present the Semi-Annual Report for Thornburg Limited Term Income
Fund and Thornburg  Limited Term U.S.  Government  Fund for the six month period
ending  March 31,  1997.  The net asset  value of the A shares of the  Thornburg
Limited  Term Income Fund ended the period at $12.15.  If you were  invested for
the entire  period,  you  received  dividends  of 38.4  cents per share.  If you
reinvested  your  dividends,  you received  38.9 cents per share.  Investors who
owned C shares received 35.8 and 36.3 cents per share,  respectively.  Investors
who owned I shares received 40.3 and 40.8 cents per share, respectively. The net
asset value of the A shares of the Thornburg  Limited Term U.S.  Government Fund
ended the period at $12.13.  If you were  invested  for the entire  period,  you
received  dividends of 38.0 cents per share.  If you reinvested  your dividends,
you received 38.2 cents per share.  Investors  who owned C shares  received 35.2
and 35.6 cents per share,  respectively.  Investors who owned I shares  received
39.9 and 40.5 cents per share, respectively.
Please read the accompanying exhibits for more detailed information and history.

The last six months have seen changes in the public  perception of the direction
of interest rates.  After a slight slow down in the economy last summer,  people
were expecting interest rates to continue to go lower.  However, the strength in
the economy  reasserted itself in the last quarter of 1996 and the first quarter
of 1997.  This  prompted the Federal  Reserve  Open Market  Committee to tighten
interest rate policy in its March meeting.  So now, after  initially  falling in
the fourth quarter, interest rates are a little higher than they were six months
ago. It still would not surprise me to see interest rates rise a little over the
next year. The economic reports, while mixed, are generally showing a US economy
that is moving along steadily and the economies of other developed countries are
firming as well.

The Dow Jones  Industrial  Average has recently  reached  another  record level.
Investors are still pouring money into the stock market. It might be a good time
to see whether the outsized gains over the last couple of years have  unbalanced
the asset  allocation of your  investment  portfolio.  It might be a little more
heavily weighted in stocks than you intended. It could be time to look at adding
more intermediate  bonds to your portfolio to balance the asset allocation.  The
yield level of intermediate  bonds is currently about 3 times the dividend yield
of  the  S&P  500  (currently  about  2%).  Intermediate  bonds  can  provide  a
stabilizing  presence to the principal value of a portfolio.  Intermediate bonds
have  only  had 1 down  year on a  total  return  basis  in the  last 25  years,
according to a study by Ibbotson  Associates.  And according to that same study,
intermediate  bonds  have  historically  provided  about  160% of the  return of
Treasury  Bills.  Take a look at the charts  (inside  back cover) which show the
return on an  investment  in the  Thornburg  Limited  Term  Income  Fund and the
Thornburg  Limited Term U.S.  Government Fund versus the Donoghue's Money Market
Fund average.

Your funds are laddered  portfolios of  short-to-intermediate  bonds.  We do not
speculate on the direction of interest  rates.  We keep the portfolios  laddered
over a time period  ranging from one day to  approximately  ten years,  with the
average maturity of the portfolios  always no more than five years.  Some of the
bonds are always  coming  close to  maturity,  but never too many at one time. A
bond due in May 2002  will be worth 100 when it  matures.  It may be worth 96 or
104 in the open market  today,  but it will be worth 100 when it matures.  Think
about that. Nothing has happened in the last several years of rising and falling
interest  rates to change the ultimate  maturity  value of most of the bonds you
own through  investment in these funds. We feel a laddered maturity portfolio of
short-to-intermediate bonds is a sensible strategy over time.

Thank you for  investing  in our funds.  Intermediate  bonds have proven to be a
sensible part of a portfolio. We feel the Thornburg Limited Term U.S. Government
Fund and the Thornburg Limited Term Income Fund are appropriate  investments for
investors  who  want  a  short-to-intermediate   bond  portfolio.  While  future
performance  cannot be guaranteed,  we feel that we are well positioned,  and we
will maintain a steady course.


Sincerely,



Steven J. Bohlin
Managing Director

Note 1 - ORGANIZATION

Thornburg  Limited  Term  U.S.  Government  Fund  (the  "Government  Fund")  and
Thornburg  Limited Term Income Fund (the "Income Fund"),  hereafter  referred to
collectively  as the  "Funds",  are series of  Thornburg  Investment  Trust (the
"Trust",  formerly known as Thornburg Income Trust). The Trust is organized as a
Massachusetts business trust under a Declaration of Trust dated June 3, 1987 and
is registered as a diversified, open-end management investment company under the
Investment Company Act of 1940, as amended.  The Trust is currently issuing four
series of shares of  beneficial  interest  in  addition  to those of the  Funds:
Thornburg Florida Intermediate Municipal Fund, Thornburg New Mexico Intermediate
Municipal Fund, Thornburg  Intermediate Municipal Fund and Thornburg Value Fund.
Each series is  considered to be a separate  entity for financial  reporting and
tax  purposes.  The Funds'  objectives  are to obtain as high a level of current
income as is consistent with the preservation of capital.

The Funds currently offer three classes of shares of beneficial interest,  Class
A, Class C and Institutional  Class (Class I) shares.  The Funds no longer offer
Class B shares.  Each class of shares of a Fund  represents  an  interest in the
same portfolio of  investments  of the Fund,  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 B shares  were sold at net asset
value  without a sales  charge at the time of  purchase,  but were  subject to a
contingent  deferred sales charge upon  redemption,  and bore both a service fee
and a distribution fee, (iii) Class C shares are sold at net asset value without
a sales charge at the time of  purchase,  but are subject to a service fee and a
distribution  fee,  (iv)  Class I shares are sold at net asset  value  without a
sales  charge  at the time of  purchase,  and (v) the  respective  classes  have
different reinvestment  privileges.  Additionally,  each Fund 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 Funds are limited to distribution fees,  administrative
fees and certain transfer agent expenses.

Note 2 - SIGNIFICANT  ACCOUNTING POLICIES Significant accounting policies of the
Funds are as follows:

Valuation of Investments: In determining net asset value of the Funds, the Trust
utilizes  an  independent  pricing  service  approved  by  the  Trustees.   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 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 Funds
are reviewed by the officers of the Trust under the general  supervision  of the
Trustees. Short-term instruments having a maturity of 60 days or less are valued
at amortized cost, which approximate market value.

Federal  Income  Taxes:  It is the  policy  of the  Trust  to  comply  with  the
provisions of the Internal  Revenue code  applicable  to  "regulated  investment
companies"  and to  distribute  all of their taxable  income,  including any net
realized gain on  investments  to its  shareholders.  Therefore no provision for
federal income taxes is required.



When-Issued  and  Delayed  Delivery  Transactions:   The  Trust  may  engage  in
when-issued or delayed delivery transactions.  To the extent the Trust engage in
such  transactions,  they  will do so for the  purpose  of  acquiring  portfolio
securities  consistent with their investment  objectives and not for the purpose
of investment leverage or to speculate on interest rate changes. At the time the
Trust makes a commitment to purchase a security on a when-issued  basis, it will
record the  transaction and reflect the value in determining the Funds net asset
value.  When  effecting  such  transactions,  assets  of the  Funds of an amount
sufficient to make payment for the portfolio  securities to be purchased will be
segregated on the Funds'  records at 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 Funds are declared daily as a dividend
on shares for which the Trust have received payment.  Dividends are paid monthly
and are  reinvested  in  additional  shares of the Funds 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 over the life of the respective  securities.
Realized  gains  and  losses  from the sale of  securities  are  recorded  on an
identified cost basis. The Funds invest in various  mortgage backed  securities.
Such securities pay interest and a portion of principal each month which is then
available for investment in securities at prevailing prices.

Foreign Currency  Transactions:  With respect to the Income Fund, portfolio  
securities and other assets and liabilities  denominated in foreign currencies 
are translated into U.S. dollars based on the rate of exchange of such 
currencies  against U.S. dollars on the date of valuation.  Purchases and sales
of portfolios  securities and interest  denominated in foreign currencies are 
translated into U.S. dollar amounts on the respective dates of such 
transactions.

The Fund does not isolate  that portion of the results of  operations  resulting
from changes in foreign  exchange  rates on  investments  from the  fluctuations
arising from changes in market prices of securities held. Such  fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported  net  realized  foreign  exchange  gains or losses  arise from sales of
foreign  currencies,  currency  gains or losses  realized  between the trade and
settlement  dates on  securities  transactions  and the  difference  between the
amount of interest  recorded on the Fund's books, and the U.S. dollar equivalent
of the amounts actually received or paid.

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
the 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 - 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 to the
Funds for which the fees are payable at the end of each month. For the six month
ending  March 31, 1997,  these fees were  payable at annual  rates  ranging from
three-eighths  of 1% to 11/40  of 1% of the  average  daily  net  assets  of the
Government  Fund and  one-half  of 1% to 11/40 of 1% of the  average  daily  net
assets of the  Income  Fund.  Also,  the Trust  entered  into an  Administrative
Services  Agreement with the Adviser,  whereby the Adviser will perform  certain
administrative  services  for the  shareholders  of each  class  of each  Fund's
shares,  and for which fees will be payable at an annual rate of up to 1/8 of 1%
of the average daily net assets attributable to each class of shares.

In the event  normal  operating  expenses of the Funds,  exclusive  of brokerage
commissions,  taxes,  interest,  and extraordinary  expenses,  exceed the limits
prescribed by any state in which each Fund's shares are qualified for sale,  the
Adviser will  reimburse  each Fund for such excess.  No such  reimbursement  was
required as a result of this limitation. For the six month ended March 31, 1997,
the Adviser voluntarily deferred certain operating expenses amounting to $18,789
and  $60,380  for the  Government  Fund and  Income  Fund,  respectively.  These
expenses may be repaid to the Advisor by the Fund,  however such  repayment will
depend upon the overall level of the Fund's  expenses for the entire year ending
September 30, 1997.

The Trust have  underwriting  agreements with Thornburg  Securities  Corporation
(the "Distributor"), which acts as the Distributor of the Funds' shares. For the
six month ended March 31, 1997, the Distributor earned  commissions  aggregating
$11,497  and $9,058 from the sale of Class A shares of the  Government  Fund and
Income Fund,  respectively,  and  collected  contingent  deferred  sales charges
aggregating $729 and $2,697 from redemptions of Class C shares of the Government
Fund and Income Fund, respectively.

Pursuant  to a Service  Plan under Rule 12b-1 of the  Investment  Company Act of
1940,  each Fund may  reimburse to the Adviser an amount not to exceed .25 of 1%
annum of its average net assets for payments  made by the Adviser to  securities
dealers and other financial  institutions to obtain various  shareholder related
services.  The  Adviser  may pay out of its own funds  additional  expenses  for
distribution of each Fund's shares.

The Trust has also adopted Distribution Plans pursuant to Rule 12b-1, applicable
only to each  Fund's  Class C  shares  under  which  the  Trust  compensate  the
Distributor for services in promoting the sale of Class C shares of the Funds at
an annual rate of up to .75% of the  average  daily net assets  attributable  to
Class C shares.  Total fees  incurred by each class of shares of the Funds under
their respective  Service and Distribution  Plans for the period ended March 31,
1997, are set forth in the statement of operations.

Certain officers and trustees of the Trust are also officers and/or directors 
of the Adviser and  Distributor.  The compensation of unaffiliated  directors 
of the Trust is borne by the Trust.
