Dear Shareholder:

FISCAL 1998 WAS A CHALLENGING BUT rewarding time for Delaware Investments' eight
midwest and northwest municipal bond funds. Tax-exempt bonds provided
attractive, high single-digit returns during a period of increased stock market
volatility and global economic uncertainty.
        Since August 1997, municipal bond supplies have increased substantially
in many states, with education, health care and transportation issues leading
the way. This provided the Funds' portfolio manager, Elizabeth H. Howell, ample
opportunity to select bonds with attractive yields, total return potential and
favorable credit characteristics.
         We have changed the Funds' fiscal year end to August 31 to match the
fiscal year end of Delaware Investments' national municipal bond funds. We
believe this alignment may increase operational efficiency over the long term.
From now on, you will receive an annual report by early November and a
semi-annual report by May.
        Total returns of each Fund in fiscal 1998 were competitive with the
unmanaged Lehman Brothers Bond Indexes shown below as well as each Fund's
respective peer group (for Class A shares at net asset value with distributions
reinvested).
        Of special note is that the total returns provided by each of the eight
state funds in this report outpaced the +8.10% total return of the Standard &
Poor's 500 Index for the 12 months ended August 31, 1998.

FOR BOND INVESTORS, THE U.S. ECONOMIC ENVIRONMENT HAS BEEN CLOSE TO IDEAL.

While such results might seem unusual given the ebullient stock market of the
1990s, extended periods of higher returns from bonds rather than stocks have
been common in the 20th Century.
        For example, bonds (as measured by the Lehman Brothers Municipal Bond
Index) outpaced stocks (as measured by the S&P 500) for the 10-year period from
1972 to 1982, a time of high inflation, recession and global political
instability.
        Fortunately for today's tax-exempt bond investors, inflation is low and,
in the view of most economists, a domestic recession is unlikely. Most states
enjoy high credit ratings and have been benefiting from rising tax revenues.
Indeed, in the summer of 1998, income and other taxes were pouring into
municipal coffers at the fastest pace in eight years, according to the Nelson
Rockefeller Institute of Government, a think tank in Albany, New York.
        We view the municipal debt market's current prospects as compelling,
especially when viewed against taxable fixed-income alternatives. Cash flows
into municipal bond mutual funds have accelerated in recent months as equity
investors have sought to diversify their portfolios, reduce risk and minimize
taxes.
        We encourage you to review your asset allocation plan with your
financial and tax advisers to examine the potential benefits of increasing your
position in a single-state tax-exempt fund and other tax-advantaged investment
opportunities offered through Delaware Investments.

Sincerely,

Portfolio Manager's Review

BY ELIZABETH H. HOWELL

Vice President/Senior Portfolio Manager
September 11, 1998

SINCE AUGUST 1997, TAX-EXEMPT BOND prices have benefited from strong domestic
growth, high average credit quality and state fiscal prudence. The one problem
facing the municipal bond market has been a huge increase in bond supplies as
municipalities have sought to refinance debt at lower interest rates.
        The bond market absorbed unusually large increases in volume in many
regions of the country, including Iowa, Missouri and Kansas, states that
historically have not issued many bonds. Supplies in these three states have
risen more than 70% in 1998 from year earlier levels, and are up 43.7%
nationwide according to The Bond Buyer, a trade publication.
        Yet even with all this additional supply, municipal bonds provided
excellent returns during fiscal 1998. In fact, for the six months ended August
31, 1998 the unmanaged Lehman Brothers Municipal Bond Index rose +3.44% while
stocks, as measured by the unmanaged Standard & Poor's 500 Index, declined
8.08%.
        In managing each of the eight Funds in this report during fiscal 1998,
we sought an effective mix of average coupon, call date, and effective maturity.
As interest rates fell, we believed it was important to maintain a portfolio
with good call protection features and slightly longer-than-average durations.
        As of August 31, 1998, prices had rallied so much during fiscal 1998
that 30-year bond yields had fallen to 5.24%, the lowest level in three decades.
Just 12 months earlier, long-term Treasuries yielded 6.61%.
        U.S. government debt became the safe haven of choice for many
overseas investors as many emerging market economies grappled with recession,
currency

FOR THE SIX MONTHS ENDED AUGUST 31, 1998 THE UNMANAGED LEHMAN BROTHERS MUNICIPAL
BOND INDEX ROSE +3.44% WHILE STOCKS, AS MEASURED BY THE UNMANAGED STANDARD &
POOR'S 500 INDEX, DECLINED 8.08%.

devaluation and political instability. Municipal bond prices also rose,
though not nearly as much as Treasuries.
        In our view, the strong performance of Treasuries relative to other
bonds during the summer of 1998 was temporary. A sharp drop in global equity
markets created unusually high demand for the safest fixed-income securities. At
current price levels, we believe high quality, long-term municipal bonds offer
exceptional value and relatively modest risks.
        Given the high volume of U.S. stock trading this past summer, we believe
many equity mutual fund investors could receive large capital gains
distributions this fall - and thus have higher 1998 income tax liabilities. We
feel many equity investors will see it makes more sense from a tax perspective
to reduce their portfolios' risk profile by allocating assets to municipal bonds
rather than Treasuries. That is because Treasury income increases an investor's
federal and, in many cases, state tax burden.

TAX-FREE IDAHO FUND
Tax-Free Idaho Fund provided a strong total return of +9.02% for the 12 months
ended August 31, 1998 (for Class A shares at net asset value with distributions
reinvested). The Fund's results outpaced the +7.74% average of its peers, as
measured by Lipper Analytical Services and shown on page 1.
        By keeping the Fund's duration slightly longer than other mutual funds
investing in Idaho bonds, we were able to provide exceptionally attractive
results. We provided higher-than-average tax-exempt income and captured most of
the bond market's total return potential.
        During fiscal 1998, more than half of Tax-Free Idaho Fund's net assets
were invested in investment grade (mostly A and BBB) and unrated bonds.
        Prices of unrated securities rose more than higher quality bonds as the
state's economy remained strong and investors were attracted by relatively
higher yields.
        Overall, the state's municipalities issued $477 million in bonds for the
first eight months of 1998, a relatively modest amount compared to most states,
according to The Bond Buyer. Still, this amount was a 48% increase over the same
period in 1997.
        In selecting bonds for Tax-Free Idaho Fund, we attempt to balance the
portfolio with investment grade and unrated bonds that produce an above-average
interest rate and bonds that can contribute to total return. During the year, we
modestly increased our weighting in the pollution control and higher education
sectors and exchanged some higher coupon hospital bonds for discount bonds.
        For example, in July we purchased 5.45% bonds issued by the Elks
Rehabilitation Hospital in Boise, which specializes in helping victims of brain
injury and stroke. We acquired an approximately $1 million position at a
discount to par in July and by August 31 the bonds had appreciated to a price of
$100.43. With a bond rating of


DURING FISCAL 1998, MORE THAN HALF OF TAX-FREE IDAHO FUND'S NET ASSETS WERE
INVESTED IN INVESTMENT GRADE (MOSTLY A AND BBB) AND UNRATED BONDS.

BBB from S&P, the hospital has been consistently profitable for the past five
years.
        As of late summer, Idaho's unemployment rate was 4.9%, low by historical
standards. Thanks in part to tourism, state economists expect Idaho's economy to
grow faster than the national economy over the next several years, although the
short-term outlook for the state's high technology sector is unclear. Micron
Technology, a leading employer, reported in July that demand for dynamic random
access memory chips (DRAMs - a key product in many computers), is beginning to
recover after a sharp drop during the first half of calendar 1998.

TAX-FREE IOWA FUND
Tax-Free Iowa Fund provided a total return of +8.18% for the 12 months ended
August 31, 1998 (for Class A shares at net asset value with distributions
reinvested). This exceeded the +7.74% average return of the Fund's peer group
for the period, as measured by Lipper Analytical Services and shown on page 1.

        Iowa municipalities have historically issued relatively few bonds that
are exempt from both federal and state taxes. Although bond supplies increased
more than 70% to $1.3 billion from a year ago, according to The Bond Buyer,
so-called double tax-exempt bonds remained scarce. Still, we boosted the amount
of your Fund's net assets invested in Iowa bonds and reduced the Fund's position
in territorial bonds (bonds issued by Puerto Rico, Guam and the Virgin Islands)
in fiscal 1998.
        Territorial bonds, which are exempt from federal and state income taxes
in all states, provide an additional element of diversification for the Fund and
help us meet our income, duration and total return objectives.
        Iowa enjoyed healthy economic growth in fiscal 1998. The state's
unemployment rate was 2.5% as of August, among the lowest in the country, and
land values are rising. However, expected bumper crops of corn and soybeans have
depressed selling prices for farmers, leading to a reduction in farm income and
related state tax revenues.

Corn futures on the Chicago Mercantile Exchange were at their lowest level in 10
years as of early September.
        Another economic issue Iowans will have to grapple with in the coming
year is a surplus of hogs amid weak export demand for pork from key markets such
as Japan and the Pacific Rim. Government figures show America's pig population
is at an 18-year high and growing. More sows are giving birth and the number of
piglets per sow has risen to a near record 8.7, according to the U.S. Department
of Agriculture. Iowa raises more hogs than anywhere else, and wholesale pork
prices have fallen to $0.33 a pound, less than the $0.40 a pound it costs most
farmers to raise a pig.
        Thus far, agricultural sector weakness has not affected the state's bond
market or most municipal credit ratings. The Fund has only limited exposure to
economic development bonds tied to farming. Tax-Free Iowa Fund's largest holding
as of August 31, 1998 was a bond issue of the Iowa Finance Authority Underground
Storage Tank (12% of net assets).

TAX-FREE KANSAS FUND
Tax-Free Kansas Fund provided a robust total return of +9.17% for the 12 months
ended August 31, 1998 (for Class A shares at net asset value with distributions
reinvested). This was higher than the returns of both the unmanaged Lehman
Brothers Municipal Bond Index (see chart on page 1) and the average of the
Fund's 12 peers (+7.67%).
        Bond supplies in Kansas rose a sharp 84.9% during the first eight months
of calendar 1998 to $1.5 billion, according to The Bond Buyer. Most of the
issues that came to market were given high ratings by Moody's Investors Services
or Standard & Poor's.
        Kansas' economy, while strong, has generally not been quite as dynamic
as some neighboring states. The jobless rate was a low 3.5% as of August. As of
the end of summer, growth in the state's manufacturing sector was beginning to
slow, according to a survey of factory managers by the Federal Reserve Bank of
Kansas City, Missouri.
        Falling overseas demand for wheat amid bumper U.S. crops has hurt
Kansas' farming sector, which grows more wheat than any other state. Export
demand to emerging market countries has fallen 30% from year ago levels. More
countries have lacked the resources to buy American grain, which has become more
expensive

because the dollar has risen in value against many currencies, according to the
U.S. Department of Agriculture. During the summer, the USDA announced plans to
buy 80 million bushels of wheat to boost prices and feed famine victims in
Africa.
        Our approach to bond credit quality given this economic backdrop can
best be described as a barbell strategy. Approximately a quarter of the Fund's
net assets were invested in bonds rated AAA, the highest quality bonds available
during the year. This provided the Fund with an element of safety of principal.
Another 40% was invested in medium quality and unrated bonds, which provided
above-average income and total return during fiscal 1998.
         We only purchase unrated bonds that we conclude would qualify for an
investment grade rating if the issuer had sought one. We attempt to balance the
portfolio between unrated bonds that produce an above-average interest rate and
rated bonds that can contribute to total return. As a result of our credit
selections, we were able to provide a very attractive income stream at a
moderate level of risk.
        During the second half of fiscal 1998, we increased the Fund's average
duration to 7.5 years in anticipation that interest rates will continue to fall
during the first half of fiscal 1999. We continue to seek rated bonds that have
higher-than-average call protection and good structural characteristics, as well
as unrated bonds we believe offer strong total return potential.

Missouri Insured Fund provided a total return of +8.12% for the 12 months ended

average of 23 insured municipal bond funds specializing in Missouri bonds, most
of which invest primarily in uninsured bonds.

return that outpaced the total return of the Standard & Poor's 500 Index for the
12 months ended August 31, 1998. Missouri Insured Fund invests exclusively in
bonds that are rated AAA by Moody's Investors Services or Standard & Poor's.
        Insured Missouri bonds generally did not offer as much total return
potential as bonds in some other states because of the huge increase in new
issuance. The state's municipalities issued more than $3.4 billion in bonds
between January and August 1998, an 80% percent increase from year earlier
levels, according to The Bond Buyer. This additional supply was difficult for
the market to absorb.
        Still, market appreciation reduced the average effective duration of
Tax-Free Missouri Insured Fund by several months to 6.4 years as of August 31.
The Fund's positioning was about a half-a-year shorter than the Lehman Brothers
Insured Municipal Bond Index, the Fund's benchmark.
         As of August 1998, the unemployment rate in Missouri stood at 4.1%,
somewhat higher than surrounding states. Economic growth was moderate, and
factory managers in the state were anticipating a modest slowdown through the
end of the year in shipments of goods and the average production workweek,
according to a report by the Federal Reserve Bank of Kansas City.
        For fiscal 1999, we believe Missouri bonds offer attractive income and
total return opportunities, especially for investors in the top combined federal
and state tax bracket of 43.2%. Yields on long-term insured Missouri bonds were
at their highest levels relative to 30-year U.S. Treasury bond yields in more
than nine years as of August 31.

TAX-FREE NORTH DAKOTA FUND
For the 12 months ended August 31, 1998, Tax-Free North Dakota Fund provided a
higher-than-average total return of +8.37% (for Class A shares with
distributions reinvested at net asset value).
        The Fund did well relative to its peers because we positioned the
portfolio for a gradual decline in interest rates. Average duration was longer
than the Lehman Brothers Municipal Bond Index for the period. This allowed the
Fund to generate an attractive level of income and participate in the bond
market's spring rally.

         One factor helping lift North Dakota bond prices was that supply was
scarce. Only $406 million in new bonds were issued between January and August,
one of the lowest rates of issuance in the nation. Only the states of Delaware,
Vermont and Wyoming have issued fewer bonds so far this year.
        North Dakota's short-term economic prospects were clouded in early
September by the two-week strike at Northwest Airlines, the only airline that
serves the state. During the strike, the Clinton Administration ordered
Northwest's commuter airline affiliate to resume flights to North Dakota after
an appeal for help from the state's Congressional delegation.
        Fortunately, many of the state's top employers such as health care
providers generally do not depend on air travel. We believe the effects of the
strike will prove temporary and not adversely affect the credit quality of the
state's municipal bonds.
        Of more lasting concern is North Dakota's weak agricultural sector.
While some states expect bumper crops this year, North Dakota's farmers have
been plagued by the wheat scab fungus, which grows when planting conditions are
too wet. Wheat prices are the lowest since 1991, and farm liquidations have
increased this year, according to the U.S. Department of Agriculture.
        Tax-Free North Dakota Fund's single largest sector weighting as of
August 1998 was hospital bonds. This sector generally offers higher yields and
we believe that selected hospital bonds may also benefit from ratings upgrades
as stronger hospital chains absorb smaller and less well-capitalized
institutions.
        North Dakota's unemployment rate was just 2.2% as of August, one of the
lowest rates of joblessness in the country. Home building activity in the state
was brisk in major towns such as Fargo this past spring, according to a report
by the Ninth Federal Reserve District.
        High quality North Dakota bonds remain the dominant element of Tax-Free
North Dakota Fund's portfolio. During the second half of fiscal 1998 we added
medium quality bonds to increase the Fund's income potential. We were
underweighted in lower rated industrial development bonds, and this helped the
Fund's performance.

TAX-FREE OREGON INSURED FUND
Tax-Free Oregon Insured Fund provided an above-average total return of +8.78%
for the 12 months ended August 31, 1998 (for Class A shares at net asset value
with distributions reinvested).
        The Fund's performance for the period outpaced the +7.78% average of its
25 peers as shown on page 1. Tax-Free Oregon Insured Fund's relatively long
duration and focus on insured bonds, which tend to benefit more from interest
rate declines than non-insured bonds, enhanced our results.
        Bond supplies in Oregon increased during the first eight months of
calendar 1998. More than $1.3 billion worth of bonds have been issued since
January, a 21% increase from year ago levels, according to The Bond Buyer.
Since Oregon has relatively high tax rates and has

historically issued a relatively limited number of bonds for a state of its
size, investors easily absorbed the increase.
        One event affecting Oregon's bond market in 1998 was a downgrading of
the state's general obligation bonds from AA+ to AA by Standard & Poor's on July
7. The Fund's performance relative to its peers benefited from our avoidance of
state-issued general obligation bonds. To provide an element of safety, the Fund
invests exclusively in bonds that are insured by one of the major municipal bond
insurance companies and are rated AAA by Moody's and/or Standard & Poor's rating
agencies.
        In fiscal 1998, we emphasized bonds with discount coupons, good call
protection, and long maturities. We reduced our positioning in municipal general
obligation bonds and increased our weighting in power authority and other
revenue bonds. Pursuing this strategy allowed the Fund to perform well even as
investor fears concerning the possible impact of Asia's recession on Oregon's
economy have grown.
        While Oregon's natural resource exports such as paper have slowed, the
state's economy appears to be holding up. Strength in housing and consumer
spending are offsetting weakness in factory activity, according to a June report
by the Twelfth Federal Reserve District.

        We will keep a close eye on developments overseas and how they might
affect Oregon's municipal bond market in the coming year. Exports to Asia
account for about 7% of Oregon's gross state product, state officials estimate.
About half of the state's exports are agricultural products such as timber.

TAX-FREE WASHINGTON
INSURED FUND
Tax-Free Washington Insured Fund provided exceptionally strong results for
fiscal 1998. For the 12 months ended August 31, 1998, the Fund's total return
was +9.44% (for Class A shares at net asset value with distributions
reinvested). This was higher than the Fund's benchmark and the +8.71% average
return of the Fund's eight peers.
         After a surge in new issuance in 1997, new bond supplies in the State
of Washington have increased only marginally in calendar 1998. Through August,
$3.7 billion in bonds were issued, a 4.7% increase from a year ago, according to
The Bond Buyer.
         Washington's steady bond supply, coupled with strong investor demand,
helped Washington bonds outperform bonds of other states.

         In early September, Standard & Poor's affirmed its AA rating for
Washington's general obligation bonds, saying that the state enjoys a
diversified economy that is "exhibiting resilience to cyclicality in aerospace
and other trade-related sectors."
        Washington's economic expansion is likely to continue, according to S&P,
despite reduced trade with Asia and job cuts at jet maker Boeing. Washington
leads the nation in exports relative to gross state product, and one-sixth of
the state's jobs are tied to international trade. Through the summer of 1998,
however, the Pacific Rim's economic turmoil had not affected the state's budget
or budget forecast.
        Tax-Free Washington Insured Fund did well relative to the Lehman Insured
Municipal Bond Index and its peers because we positioned the Fund for a decline
in interest rates. The Fund's duration, or sensitivity to interest rate
movements, was modestly longer than that of the index. This allowed us to
achieve a high rate of total return as bond prices rose.
         In fiscal 1998, the Fund focused on bonds with discount coupons, good
call protection, and long maturities. The Fund invests exclusively in bonds that
are insured by a leading municipal bond insurance company and are rated AAA.
        During the second half, the Fund reduced its weighting in housing bonds
and increased its weighting in higher education bonds. Housing bonds, because of
the risk of prepayment from underlying mortgages, tend to yield more than bonds
from other sectors that have similar ratings and maturities. Given our view that
interest rates will decline in the months ahead, we believed it was prudent to
reduce exposure to prepayments, especially in the single family home segment.
        Even though Washington does not have a state income tax, the market for
tax-exempt securities is robust, and likely to grow. Incomes in Washington are
about 10% higher than the national average. Many residents have also enjoyed
huge capital gains during the 1990s as stocks of high-tech companies such as
Microsoft Corp. have appreciated. In our view, some of the gains realized on
equity investments could be reallocated to the state's municipal bonds in the
year ahead, especially if the stock market remains volatile.

WASHINGTON'S GENERAL OBLIGATION BONDS.

TAX-FREE WISCONSIN FUND
For the 12 months ended August 31, 1998, Tax-Free Wisconsin Fund provided a
total return of +8.13% (for Class A shares at net asset value with distributions
reinvested). This was higher than the average of the Fund's peers as shown on
page 1.
        We attribute the Fund's performance to the Fund's substantial investment
in health care and housing bonds, two sectors that provided above-average income
but did not appreciate as much as other sectors during fiscal 1998.
        Since the summer of 1997, the credit quality of most Wisconsin
municipalities has been excellent. In early September, Standard & Poor's
affirmed its high AA rating for the state's general obligation bonds. The rating
agency said its rating reflected a diversified Wisconsin economy that exhibits
steady growth, sound financial performance and a moderate overall debt burden.
        More than $3.14 billion worth of new bonds were issued in Wisconsin
during the first eight months of calendar 1998, a 23% increase from the prior
year, according to The Bond Buyer. We used this increase in supply to add more
Wisconsin bonds to your Fund's portfolio and sell some Puerto Rico territorial
bonds that had appreciated in value.
        Territorial bonds, which are exempt from both state and federal income
taxes, provide an additional element of diversification for the Fund and help us
meet our income, duration and total return objectives.
        As of August 31, slightly more than half of your Fund's net assets were
invested in investment grade bonds (A and lower) and unrated bonds. These bonds
generally have a higher-than-average coupon, increasing the Fund's income
potential. All bonds in Tax-Free Wisconsin Fund generate income that is exempt
from both federal and state income taxes.
        Many Wisconsin issues finance small municipal projects that are too
small to make it economically feasible to seek a rating from Moody's Investors
Services or Standard & Poor's. We carefully evaluate each issue to determine
creditworthiness. We balance unrated bonds that produce an above-average
interest rate with bonds that are rated and can contribute to the Fund's total
return.
        Wisconsin's 3.2% unemployment rate as of August was relatively low. In
its report, S&P said the services and trade sectors are expected to account for
about 70% of the state's new jobs this year. Employment growth has averaged 2%
annually since 1992, a pace that S&P expects to slow to about 1% through the
year 2000.
        Wisconsin is expected to post a budget surplus of $352 million in 1998,
up from $327 million a year earlier. S&P said its positive outlook for the state
reflects an expectation that Wisconsin will increase its budget reserve, meet
greater educational funding requirements and provide property tax relief.

All performance includes reinvestment of distributions and applicable sales
charges as described below. Return and share value will fluctuate so that shares
when redeemed may be worth more or less than the original cost. Past performance
is not a guarantee of future results. Performance for Class B and C shares
excluding sales charge assumes either contingent sales charges did not apply or
the investment was not redeemed. Returns reflect a voluntary expense limitation
in effect at the time. Returns would have been lower without the limitation.

CLASS A shares have a 3.75% maximum front-end sales charge. All Funds have a
12b-1 fee.

CLASS B shares do not carry a front-end sales charge, but are subject
to a 1% annual distribution and service fee. They are also subject to a deferred
sales charge of up to 4% if redeemed before the end of the sixth year.

CLASS C shares have a 1% annual distribution and service fee. If shares are
redeemed within 12 months, a 1% contingent deferred sales charge applies.

NOTES TO FINANCIAL STATEMENTS
AUGUST 31, 1998

Delaware-Voyageur Tax-Free Kansas Fund ("Tax-Free Kansas Fund"),
Delaware-Voyageur Tax-Free Missouri Insured Fund ("Tax-Free Missouri Insured
Fund"), Delaware-Voyageur Tax-Free Oregon Insured Fund ("Tax-Free Oregon Insured
Fund"), and Delaware-Voyageur Tax-Free Washington Insured Fund ("Tax-Free
Washington Insured Fund"), series within the Voyageur Investment Trust,
Delaware-Voyageur Tax-Free Idaho Fund ("Tax-Free Idaho Fund"), Delaware-Voyageur
Tax-Free Iowa Fund ("Tax-Free Iowa Fund"), and Delaware-Voyageur Tax-Free
Wisconsin Fund ("Tax-Free Wisconsin Fund"), series within the Voyageur Mutual
Funds, Inc., and Delaware-Voyageur Tax-Free North Dakota Fund ("Tax-Free North
Dakota Fund"), a series within the Voyageur Tax-Free Funds, Inc. (each referred
to as a "Fund" or collectively as the "Funds") are registered as
non-diversified, open-end management investment companies under the Investment
Company Act of 1940 (as amended). The Funds offer three classes of shares. The A
Class carries a front-end sales charge of 3.75%. The B Class carries a back-end
deferred sales charge and the C Class carries a level load deferred sales
charge.

The Tax-Free Idaho Fund, Tax-Free Iowa Fund, Tax-Free North Dakota Fund, and
Tax-Free Wisconsin Fund seek high current income free from both federal and
state income taxes by investing in investment grade municipal bonds. The
Tax-Free Missouri Insured Fund, Tax-Free Oregon Insured Fund and Tax-Free
Washington Insured Fund seek high current income free from both federal and
state income taxes with the added safety of an insured portfolio by investing in
insured municipal bonds. The Tax-Free Kansas Fund seeks high current income free
from both federal and state income taxes and local intangibles tax by investing
in investment grade municipal bonds.

The Funds have changed their fiscal year ends from December 31 to August 31 to
match the fiscal year end of Delaware Investments' national municipal bond
funds.

1. Fund Reorganization
On April 30, 1997, Lincoln National Corporation ("LNC") acquired Voyageur Fund
Manager Inc.'s ("Voyageur") parent, Dougherty Financial Group, Inc. ("DFG")
pursuant to an agreement and plan of merger dated January 15, 1997, in which LNC
acquired DFG including the mutual fund investment advisory business of DFG
conducted by Voyageur. Upon completion of the acquisition, Delaware Management
Company, Inc. ("DMC") became the investment advisor to the Funds, Delaware
Distributors, L.P. ("DDLP") became the distributor for the Funds, and Delaware
Service Company, Inc. ("DSC") became the transfer, dividend-disbursing,
shareholder servicing and accounting and administrative agent for the Funds.
DMC, DDLP and DSC assumed these services under substantially similar fee
structures that were in effect prior to the acquisition.

2. Significant Accounting Policies
The following accounting policies are in accordance with generally accepted
accounting principles and are consistently followed by the Funds.

Security Valuation - Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Money market instruments having less than 60 days to maturity are
valued at amortized cost which approximates market value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Funds' Board
of Directors.

Federal Income Taxes - Each Fund intends to continue to qualify as a regulated
investment company and make the requisite distributions to shareholders.
Accordingly, no provision for federal income taxes has been made in the
financial statements. Income and capital gain distributions are determined in
accordance with federal income tax regulations which may differ from generally
accepted accounting principles.

Class Accounting - Investment income, common expenses and realized and
unrealized gain (loss) on investments are allocated to the various classes of
the Funds on the basis of daily net assets of each class. Distribution expenses
relating to a specific class are charged directly to that class.

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 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.



<PAGE>



Other - Expenses common to all funds within the Delaware Investments Family of
Funds are allocated amongst the funds on the basis of average net assets.
Security transactions are recorded on the date the securities are purchased or
sold (trade date). Costs used in calculating realized gains and losses on the
sale of investment securities are those of the specific securities sold.
Interest income is recorded on the accrual basis. Original issue discounts and
market premium are amortized to interest income over the lives of the respective
securities. The Funds declare dividends from net investment income daily and pay
such dividends monthly. Capital gains, if any, are distributed annually.

Certain expenses of the Funds are paid through "soft dollar" arrangements with
brokers. The amount of these expenses is less than 0.01% of the Fund's average
daily net assets.

3. Investment Management and Other Transactions with Affiliates
In accordance with the terms of the Investment Management Agreement, each Fund
pays DMC, the Investment Manager of each Fund, an annual fee which is calculated
daily based on the net assets of each Fund.

DMC has elected to waive its fees and reimburse each Fund to the extent that
annual operating expenses exclusive of taxes, interest, brokerage commissions,
distribution fees, and extraordinary expenses do not exceed the following
percentages of average daily net assets through December 31, 1998.

6. Lines of Credit
The Funds have committed lines of credit for the following amounts:

Tax-Free Idaho Fund .............................................  $2,100,000
Tax-Free Iowa Fund ..............................................   2,100,000
Tax-Free Kansas Fund ............................................     700,000
Tax-Free Missouri Insured Fund ..................................   3,000,000
Tax-Free North Dakota Fund.......................................   1,600,000
Tax-Free Oregon Insured Fund.....................................   1,500,000

Tax-Free Wisconsin Fund .........................................   1,700,000

No amounts were outstanding at August 31, 1998, or at any time during the fiscal
year.


7. Credit And Market Risk
The Funds concentrate their investments in securities mainly issued by each
specific states' municipalities. The value of these investments may be adversely
affected by new legislation within the state, regional or local economic
conditions, and differing levels of supply and demand for municipal bonds. Many
municipalities insure repayment for their obligations. Although bond insurance
reduces the risk of loss due to default by an issuer, such bonds remain subject
to the risk that market value may fluctuate for other reasons and there is no
assurance that the insurance company will meet its obligations. These securities
have been identified in the Statement of Net Assets.

To the Shareholders and Board of Directors
Voyageur Mutual Funds, Inc. - Delaware-Voyageur Tax-Free Idaho Fund
Voyageur Mutual Funds, Inc. - Delaware-Voyageur Tax-Free Iowa Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free Kansas Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free Missouri Insured Fund
Voyageur Tax-Free Funds, Inc. - Delaware-Voyageur Tax-Free North Dakota Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free Oregon Insured Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free Washington Insured Fund
Voyageur Mutual Funds, Inc. - Delaware-Voyageur Tax-Free Wisconsin Fund

We have audited the accompanying statements of net assets of Tax-Free Idaho
Fund, Tax-Free Iowa Fund, Tax-Free Kansas Fund, Tax-Free Missouri Insured Fund,
Tax-Free North Dakota Fund, Tax-Free Oregon Insured Fund, Tax-Free Washington
Insured Fund and Tax-Free Wisconsin Fund (the "Funds") as of August 31, 1998,
and the related statements of operations, statements of changes in net assets
and financial highlights for the period January 1, 1998 through August 31, 1998
and for the year ended December 31, 1997. These financial statements and
financial highlights are the responsibility of the Funds' management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The statements of changes in net
assets for the year ended December 31, 1996 and the financial highlights for the
periods presented through December 31, 1996 were audited by other auditors whose
reports thereon dated February 14, 1997 expressed unqualified opinions on those
statements and financial highlights.

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 and financial highlights. Our procedures included confirmation of
securities owned as of August 31, 1998, by correspondence with the custodian and
brokers. 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds at August 31, 1998, and the results of their operations,
the changes in their net assets and their financial highlights for the period
January 1, 1998 through August 31, 1998 and for the year ended December 31,
1997, in conformity with generally accepted accounting principles.
