Dear Shareholder:
We are pleased to present the 1997 annual report for Delaware-Voyageur's
municipal bond funds investing in Colorado, Arizona, New Mexico and Utah
securities. All four states benefited from strong economic growth last year
that increased tax revenues.
        Each of our five Funds outperformed the average of its peers for the 
12 months ended December 31, 1997 (for Class A shares with distributions 
reinvested at net asset value) as shown below. Increased employment in the 
Southwest and Rocky Mountain region's high-technology sector enabled all four 
states to post budget surpluses last year. This growth also helped support 
each state's credit rating.
        We participated in the bond market's summer and autumn rally as
investors grew more confident in the Federal Reserve Board's ability to keep
inflation in check. Consumer prices rose just 1.7% in 1997 - the smallest
increase since 1986.
        At year-end, the difference in the U.S. Treasury Bond's short-term 
and long-term interest rates, known as the yield curve, was the smallest 
since 1993. Also, the potential income advantage offered by lower quality 
municipal bonds, compared to bonds rated AAA, narrowed. 
        Fiscal 1997 was a banner year for municipal bonds. Among the 
favorable developments during the period were:
  o  Passage of the Taxpayer Relief Act in July. This lifted the specter of 
   proposed federal tax legislation that could have made municipal bonds a 
   less attractive investment option.
  o  Rising Tax Revenues. Thanks to strong job growth and corporate profits, 
   many states, including the

  four discussed in this report, posted budget surpluses last year.

   o        Steady investor demand. Although the amount of new bonds issued 
   in most Southwestern and Rocky Mountain states increased in 1997, a steady 
   stream of investors helped support bond prices. Bond prices got an 
   additional boost in Utah as the amount of new bonds coming to market fell 
   19% to $1.8 billion, according to The Bond Buyer, a trade publication.
        We view the municipal bond market's long-term prospects as 
attractive, especially since the IRS and many states still tax income at a 
higher rate than capital gains.
        On the pages that follow, the Funds' portfolio managers explain their 
disciplined investment strategy which is designed to help you benefit from 
the income and total return potential of each state's municipal bond market. 
On behalf of Delaware Investments, we wish you well in 1998. We hope you find 
our new annual report format informative.

Portfolio Managers' Review

The 1997 fiscal year was perhaps the most significant time for the municipal
bond market since federal tax laws were overhauled in 1986. The Taxpayer
Relief Act of 1997, passed in July, offered provisions that we believe are
beneficial to municipal bond mutual fund investors. Consider that the law:
  o  Increased the after-tax total return potential of municipal bonds by 
   cutting the long-term capital gains tax from 28% to as low as 20%; and
  o  Maintained municipal bonds' potential after-tax income advantage over 
   bonds that generate taxable income because Congress did not reduce taxes 
   on dividends.
         In recent years, Congress has given the states more autonomy in
managing fiscal, social and public works programs. Thus, we believe it has
become more important than ever to consider the impact of both state and
federal income taxes on the performance of an investment portfolio.
         Many states took advantage of low interest rates in 1997 to refinance
old debt and issue new debt for municipal projects. The Southwestern and Rocky
Mountain region's growth and demographic makeup generate a substantial need
for public financing for roads, schools, water treatment facilities and
hospitals.
         Colorado issued $5.1 billion in new bonds in 1997, a 61% increase
from a year earlier, while Arizona issued $3.1 billion in new bonds, a 60%
increase. Bond supplies in New Mexico rose 10% to $1.4 billion. (Source: The
Bond Buyer).

The chart to the left shows how much an investor in the highest federal tax
bracket (39.6%) residing in each state would have to earn from a taxable
investment to match the income potential of long-term municipal bonds in each
respective state.

Tax-Free Colorado Fund 
Strategic Positioning
Tax-Free Colorado Fund capitalized on the state's diverse economy and 
provided an attractive total return of +11.40% (Class A shares with dividends 
reinvested) for the 12 months ending December 31, 1997, as shown on page 1. 
The Fund's results ranked 2nd out of 23 mutual funds in its peer group as 
measured by Lipper Analytical Services.+ 
        During 1997, we have increased our position in hospital bonds, which 
currently account for approximately 25.0% of the Fund's net assets. We 
believe that consolidation in the health care industry is creating attractive 
income and total return opportunities as hospitals strive to be more 
cost-efficient. As we evaluate bonds within the sector, we seek hospitals 
that appear to show an ability to expand revenues and maintain profitability.
        In 1997, we also had a strong weighting in general obligation bonds,
which provided superior returns as the state's economy boomed. For the year
ahead, however, we expect to reduce our weighting in this category, partly in
response as a result of the passage of the Tabor Amendment by the Colorado
Legislature. This Amendment placed a constitutional cap on spending and
restricts the state's ability to issue general obligation bonds by requiring
voter consent.
        In the future, we believe a larger percentage of the state's 
municipal securities will be revenue bonds. Such bonds are supported by the 
revenue stream of a particular project - a toll road, a hospital or a water 
treatment plant - rather than income tax dollars. 
        For fiscal 1998, we believe new development in Denver has made the 
city's bonds attractive to investors. We recently purchased a transportation 
bond for a toll highway that starts just south of the City and leads to 
Denver International Airport. The airport's popularity has exceeded 
expectations, and we believe the highway will benefit from the airport's 
growth.

         Also in Denver, the Colorado electorate is expected to vote in 1998
on whether general obligation bonds should be issued to finance the
construction of a new stadium for the Superbowl champion Denver Broncos. With
the hoopla surrounding the team after their January 25th victory, we
anticipate this financing effort will be well-received by the public and the
bond market. As with any new bond, we will examine these securities when
issued to see if they can help us meet the Fund's goals.
        One source of concern for 1998 is that consumer price inflation is 
higher in Colorado than some other states. Prices rose at a 3.5% clip in 
1997, double the national average of 1.7%, U.S. Government figures show. This 
was offset by 6.5% growth in personal income - a rate that has been and is 
expected to be much higher than the national average. Colorado residents' per 
capita income ranks 10th nationwide. 


Tax-Free Arizona Funds 
Strategic Positioning
Tax-Free Arizona Fund provided a strong total return of +10.07% for the 12 
months ended December 31, 1997, as shown on page 1. Our results ranked 2nd 
among 37 mutual funds investing in Arizona securities. Tax-Free Arizona 
Insured Fund's total return was +8.96% for the same period. (For both Funds, 
returns are for Class A shares at net asset value with distributions 
reinvested.)
        Insured bonds carry the protection of private insurance in case of 
default, and the cost of this insurance reduces a bond's income potential. 
Insured bonds can sometimes provide higher total returns when interest rates 
fall. However, in 1997 uninsured bonds offered higher returns because the 
state's strong economy bolstered investor confidence in bonds with moderate 
levels of credit risk.

highest quality - those rated AAA - and other investment grade bonds narrowed 
considerably, and we used this as an opportunity to selectively upgrade the 
quality of your Fund's portfolio. Each Arizona fund benefited from the 
absence of inflation in 1997 as well as from the perception that most of the 
state's municipalities were prudently managing their budgets.
        As bond prices rose during the second half of 1997, we reduced each 
Fund's duration, (a measurement of price sensitivity to interest rate 
changes) believing that the total potential of the bond market had grown  
more limited. 
        For 1998 we think investor demand for Arizona municipal bonds is 
likely to remain strong. The state's income tax brackets range from 3.0% to 
5.6%, moderate compared to neighboring California. Nevertheless, we believe 
Arizona's demographic profile suggests that many residents are 
income-oriented investors. For investors in the highest federal income tax 
bracket, tax-equivalent yields on the state's long-term bonds remain 
attractive.

Tax-Free Arizona Fund
General obligation (G.O.) bonds made up the largest component of Tax-Free 
Arizona Fund's net assets as of year's end. In Arizona, G.O.s comprise 75% of 
the municipal debt brought to market - with the majority of bonds issued for 
school districts - according to The Bond Buyer. Arizona's economic expansion 
and population growth, especially among immigrant groups, has created a need 
for more and larger schools.
        Housing bonds were the Fund's second largest sector allocation as of 
year's end - representing 15.6% of net assets. Since June, we have reduced 
our position by more than half because we believe lower interest rates have 
increased refinancing risks for certain mortgage-related securities.
        During the latter half of fiscal 1997, we added higher education 
bonds to Tax-Free Arizona Fund's investment portfolio. 

We sold some lower yielding Arizona bonds that we believed were at risk of 
being refinanced and replaced them with bonds we thought offered greater call 
protection.

Tax-Free Arizona Insured Fund
Of the two Arizona Funds, Tax-Free Arizona Insured was by far the larger in 
terms of net assets as of December 31, 1997. In part this reflects the fact 
that generally most municipal bonds issued in Arizona are protected by 
private insurance guaranteeing the payment of principal and interest when 
due.
        Tax-Free Arizona Insured Fund employed a value approach to bond 
selection in 1997 and is managed with both dividend yield and total return in 
mind.
         In the spring, amid a temporary rise in short-term interest rates, we
sold some lower yielding bonds that we believed were at risk of being
refinanced and replaced them with bonds offering greater call protection. In
our opinion, this may increase the Fund's income potential over a longer time
while maintaining a high level of quality. We believe this strategy can help
us to reduce potential security turnover and serve your Fund well should
interest rate volatility increase in the coming months.
        Since June, we have generally kept our position within each sector of 
the bond market relatively constant. We maintained a strong position in 
general obligation bonds (52.4% of net assets as of year's end). In our 
opinion, the strong performance of Arizona's economy can continue to make 
these bonds attractive.
        The second largest sector in the portfolio as of year's end was 
hospital bonds, representing 13.2% of net assets, a slight increase from 
June. Due to increased competition and consolidation in the health care 
industry, we tend to focus on hospitals with a proven record of increasing 
revenues and profitability.

months ended December 31, 1997 (for Class A shares at net asset value with 
distributions reinvested as shown on page 1.) 
        For the past five years, the Fund has consistently ranked among the 
top 10% of its peer group, according to Lipper Analytical Services. We take 
this as a sign of the effectiveness of an investment discipline that seeks to 
capitalize on both income and total return opportunities in New Mexico. The 
state posted a budget surplus of $231 million in fiscal 1997 and enjoyed a 
AA+ rating for its general obligation bonds.
        By lengthening the Fund's duration (a measurement of price 
sensitivity to interest rate changes) during the second half of 1997, we were 
able to take advantage of declining interest rates. The Fund's duration as of 
December 31, 1997 was slightly longer than that of our peers, and we believe 
this allowed the Fund to provide superior results.
        During the year, we sold some bonds with very high credit ratings and
purchased securities of more moderate quality that we believed offered an
attractive risk/reward profile. This helped to increase both the Fund's total
return and income potential.
        Housing bonds made up the largest component of your Fund at year end 
- - representing 34.9% of net assets. By focusing on higher yielding mortgage 
securities, we provided most of the income available from the longest term 
municipal bonds with much less interest rate risk. We owned bonds that fund 
multifamily housing complexes because these issues appeared to offer less 
refinancing risk than bonds issued for single-family home development.
        One housing bond with an attractive risk/reward profile that we owned 
as of year's end was issued on behalf of the Casa Hermosa Apartments in 
Hobbs, a town near the Texas border. This high yielding, unrated bond 
provided us with about 200 additional basis points (2%) of income compared to 
the average New Mexico housing bond.

Tax-Free Utah Fund          
Strategic Positioning 
Utah's economy continued to expand in 1997 thanks in part to its pro-business 
regulatory environment, low energy costs, and educated workforce. A dynamic 
economy and low inflation helped the state's bond market do well. Utah's 
unemployment rate stood at just 2.7% in 1997.
        Tax-Free Utah Fund provided a total return of +10.08% (Class A shares 
with distributions reinvested at net asset value, as shown on page 1) for the 
year ended December 31. The Fund's total return ranked 4th out of 67 funds in 
its peer group as measured by Lipper Analytical Services. The Fund's 
five-year average annual total return of +7.64% (for Class A shares) ranked 
1st out of 20 comparable mutual funds.+
        In our opinion, the Fund's portfolio structure - a mix of average 
coupon, call date and maturity - has allowed Tax-Free Utah to consistently 
provide above average results.
        During fiscal 1997, the Fund's duration (a measure of a bond's price 
sensitivity to interest rates) was longer than most of its peers. We believe 
this allowed the Fund to fully benefit from the bond market's total return 
potential as interest rates declined.
        We sold some of our higher coupon bonds during the second half and
bought bonds with a lower coupon, sometimes at prices below face value. These
discount bonds rose in price and helped us achieve superior results.
        Higher education bonds were the Fund's largest sector weighting as of 
year's end - representing 28.2% of net assets - a slight increase from 
mid-year. We believe that Utah's continual influx of new residents, 
relatively high birth rate and robust job growth will increase both 
educational demands and tax revenues in the state.
        We slightly reduced our weighting in housing bonds in 1997. While 
Utah's commercial construction market remains solid, we are concerned that 
the real estate prices in some areas may be overheating. Also, community 
resistance has made it difficult for builders to construct apartment 
buildings and single family houses in some parts of the state. 
        Our concern about the real estate market has also prompted us to 
reduce our position in Utah water and sewer bonds. Since these bonds tend to 
be funded with property tax revenues, slower than expected growth could 
increase credit risks in this sector. As of year's end, these bonds 
represented 9.7% of the Fund's net assets, compared to 17.2% a year earlier.


Fears of higher inflation were rekindled in late January 1998 after U.S. 
government reports showed labor costs rising at the fastest pace in five 
years.

Summary Outlook
The robust U.S. economy and lower interest rates helped fuel a municipal bond 
market rally in 1997, and we still believe selected bonds offer solid income 
opportunities and relatively moderate credit risk.
        However, strong U.S. economic growth and a booming job market often 
lead some bond investors to expect an acceleration in inflation because of an 
increased demand for goods and services. Those fears were rekindled in late 
January 1998 after U.S. government reports showed labor costs rising at the 
fastest pace in five years.
        We believe the positive inflation environment America has enjoyed in 
the 1990s may continue in 1998. However, as more investors and workers begin 
to enjoy the wealth and higher paychecks they've earned since the mid-1990s, 
we think it unlikely that consumer prices will grow by only 2% a year.
        One concern for the Southwest's economy is the continuing economic 
struggles of Asia. Trade with the Pacific Rim accounts for a substantial 
portion of the region's high-technology and natural resource businesses.
        In light of the economic forces we believe may affect the Southwest, 
we are constructing a more cautious investment portfolio for 1998 by seeking 
higher quality bonds for each Fund. 
        Through our selection process, we believe we can upgrade the Funds' 
portfolios with a prudent combination of average coupon, call date and 
effective maturity. By lowering the duration of each Fund during the autumn 
of 1997, we believe we have positioned the Fund to weather an increase in 
interest rate volatility.

Notes To Financial Statements

Fund)("Tax-Free Colorado Fund"), a series of the Voyageur Mutual Funds II, Inc.,
Delaware-Voyageur Tax-Free Arizona Fund (formerly Voyageur Arizona Tax Free
Fund) ("Tax-Free Arizona Fund"), a series of the Voyageur Mutual Funds, Inc.,
and Delaware-Voyageur Tax-Free Arizona Insured Fund (formerly Arizona Insured
Tax-Free Fund)("Tax-Free Arizona Insured Fund"), a series of the Voyageur
Insured Funds, Inc., are registered under the Investment Company Act of 1940 (as
amended) as open-end management investment companies. Tax-Free Colorado Fund and
Tax-Free Arizona Insured Fund are registered as diversified and Tax-Free Arizona
Fund is registered as non-diversified. Delaware-Voyageur Tax-Free New Mexico
Fund (formerly Voyageur New Mexico Tax Free)("Tax-Free New Mexico Fund") and

Fund)("Tax-Free Utah Fund"), series of the Voyageur Investment Trust, are
Massachusetts business trusts registered under the Investment Company Act of
1940 (as amended) as non-diversified, open-end management investment companies.
Tax-Free Colorado Fund, Tax-Free Arizona Fund, Tax-Free Arizona Insured Fund,
Tax-Free New Mexico Fund and Tax-Free Utah Fund, (referred to separately as
"Fund" or collectively as "Funds") seek high current income free from both
federal and state income taxes by investing in investment grade municipal bonds.
The Funds each offer 3 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. The C
Class carries a level-load deferred sales charge.

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 adviser 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 agent and accounting service agent for the Funds.


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 Fund's 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.

Other - Expenses common to all funds within the Delaware-Voyageur 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 premiums
are amortized to interest income over the lives of the respective securities.
The Funds declare dividends from net investment income daily and pay them
monthly. Capital gains are distributed annually.
<PAGE>
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.

3. Investment Management and Other Transactions with Affiliates 
Commencing May 1, 1997, and in accordance with the terms of the Investment
Management Agreement, the Funds pay DMC the Investment Manager of each Fund,
an annual fee, which is calculated daily based on the net assets of each Fund.
The management fee rates are as follows:

6. Credit and Market Risks
The Funds Concentrated 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. Inverse floaters represent
a security that pays interest at rates that increase (decrease) with a decline
(increase), in a specified index. Interest rates disclosed are in effect on
December 31, 1997.

Report of Independent Auditors

To the Shareholders and Board of Directors
Voyageur Mutual Funds II, Inc. - Delaware-Voyageur Tax-Free Colorado Fund
Voyageur Mutual Funds, Inc. - Delaware-Voyageur Tax-Free Arizona Fund
Voyageur Insured Funds, Inc. - Delaware-Voyageur Tax-Free Arizona Insured Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free New Mexico Fund
Voyageur Investment Trust - Delaware-Voyageur Tax-Free Utah Fund

We have audited the accompanying statements of net assets of Tax-Free Colorado
Fund, Tax-Free Arizona Fund, Tax-Free Arizona Insured Fund, Tax-Free New Mexico
Fund, and Tax-Free Utah Fund (the "Funds") as of December 31, 1997, and the
related statements of operations, the statements of changes in net assets and
the financial highlights for the year then ended. 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 December 31, 1997, by corres pondence 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 1997 financial statements and financial highlights present
fairly, in all material respects, the financial position of each of the
respective Funds at December 31, 1997, and the results of their operations, the
changes in their net assets and their financial highlights for the year then
ended, in conformity with generally accepted accounting principles.
