July 23, 2003

To Our Shareholders:

    We are pleased to submit to you our report for the quarter and six months
ended June 30, 2003. The net asset value at that date was $15.59. In addition,
during the quarter, three $0.115 per share monthly dividends were declared and
paid.

MIDYEAR REVIEW

    For the quarter, Cohen & Steers Advantage Income Realty Fund had a total
return, based on income and change in net asset value, of 18.9%. This compares
to the NAREIT Equity REIT Index's(a) total return of 13.1%. For the six months
ended June 30, 2003, the fund's total return was 19.1%, compared to NAREIT's
13.9%.

    At long last, nearly every sector of the U.S. financial markets provided
exceptional returns in the second quarter. REITs extended their winning streak
to over three years, and posted their best quarterly return since the fourth
quarter of 1996. In addition, the stock market arose from its three year slump
and posted its best performance (15.4% total return for the S&P 500 Index) since
the fourth quarter of 1998. Bonds extended what has now been, effectively, a
22-year bull market, with the 30-year Treasury bond registering a total return
of 5.4%.

    There was an avalanche of geopolitical and economic news in the past three
months, most of it with positive implications. War in Iraq abated while steps
toward peace in the Middle East were promising. Congress passed tax cut
legislation, with a great deal of benefit going to investors by virtue of
lowered levies on dividends and capital gains. Interest rates reached their
lowest level in over 50 years, as the Fed's accommodative monetary policy
continued unabated. Consumer and business confidence clearly began to rise, and
more Americans now own homes than ever before.

    While these positive developments have yet to ignite job creation, capital
spending and strong overall economic growth -- with the exception of
housing -- we believe that forecasts for accelerated growth in the second half
of 2003 and beyond have clearly gained credibility. We believe this renewed
optimism has helped the outlook for both real estate and REITs.

    We are very pleased with our performance relative to our benchmarks. The
strongest contributors to our out-performance were our overweight in the
regional mall sector and our underweight in the apartment, hotel and self
storage sectors. Also contributing to our out-performance was our stock
selection in the health care, apartment and industrial sectors. Our investment
in REIT preferred stocks detracted from our performance, as the total return of
these securities, though positive, lagged that of the overall REIT market.

    REITs are operating in an environment that they have never before
experienced. In nearly all of the previous cycles that we can remember, when
coming out of a recession real estate fundamentals have been dismal, property
owners were in distress, and equity and debt capital was unavailable at a
reasonable price as investors and lenders shunned the asset class. In this
cycle, however, there is virtually no distress on the part of any major property
owners. While there is no doubt that real estate fundamentals are
weak -- vacancy rates are high and many property-level cash flows have been flat
or declining -- fundamentals are more disparate across sectors than we

have ever seen coming out of a recession. Most notable is the retail sector
where occupancies and rents remain very strong. Instead of capital fleeing the
industry, it is now more plentiful than ever and has never carried a lower cost.
Investors that have been waiting for an opportunity to acquire assets at bargain
prices have been disappointed, as prices have remained firm, or even risen,
nearly across the board.

    Consequently, the opportunity set for REITs is entirely different from past
history. Instead of an asset pricing opportunity, property owners now have a
liability pricing opportunity. Record low interest rates have allowed REITs to
refinance existing higher cost debt and boost earnings, just as homeowners and
homebuyers have been doing as they finance and refinance their mortgages. In
addition, REITs have been able to take advantage of the strong demand for
property by selling assets, enabling them to reposition and upgrade the quality
of their portfolios, while simultaneously strengthening their balance sheets.
For some investors, REITs themselves are the opportunity -- there were four
major acquisitions of public REITs in the first half of the year, and we suspect
that there will be even more merger and acquisition activity in the second half
of the year.

    The strong REIT equity market offered renewed opportunities in the first
half of the year. Two initial public offerings were completed in late June, as
American Financial Realty and Maguire Properties together raised $1.4 billion in
common stock. This compares to just one IPO in 2002 (Heritage Properties), which
raised $450 million. Lower interest rates enabled REITs to tap the preferred
stock market as $1.7 billion was raised in the first half of 2003, compared to
$1.2 billion in the first half of 2002. Much of this capital was used to
refinance, at lower rates, preferred issues that reached their call dates. An
important source of demand for these securities has been mutual funds
specializing strictly in preferred stocks. REITs also issued $6.8 billion of
unsecured debt, mostly at historically low interest rates.

    Despite such market conditions, equity issuance was modest in the first half
of the year, as was demand for REIT shares. Common equity issuance, at $1.4
billion, was at a historical low and well below last year's $2.1 billion pace at
mid-year. Capital flows into real estate mutual funds were $1.6 billion,
compared to $2.5 billion in the first half of 2002. Largely due to capital
appreciation, real estate mutual fund assets stood at a record $20 billion at
mid-year, up from $15 billion just six months ago. Some observers have suggested
that REITs were relatively disadvantaged by the recent tax bill's exclusion of
REITs from the lowered 15% dividend tax rate for investors, because REITs
already don't pay taxes at the corporate level. Nonetheless their substantial
dividend yield potential (still superior to nearly all alternatives on an
after-tax basis) and growth potential have enabled REITs to remain the
investment of choice for many real estate and income-oriented investors.

    Finally, the matter of corporate governance has become one of the most
important issues in the financial world. As the nation's leading REIT investor
and a very long-term holder of these securities, we view corporate governance as
one of our most important responsibilities. While REITs in general tend to score
rather well in comparison to other industries, many concerns remain. In the
proxy-voting period of 2003, Cohen & Steers voted in opposition to management
proposals or directors on 22 separate occasions. Most of these related to poison
pills, board classification and independence, and compensation. Our emphasis on
corporate governance issues is not new; in 2002 we voted in opposition to
management 17 times, and in 2001, 21 times.

INVESTMENT OUTLOOK

    In our opinion, the single most important investment variable today relates
to the current interest rate climate and the prospect of a low-return
environment for the foreseeable future. We have experienced a secular

- --------------------------------------------------------------------------------

re-pricing of the cost of money, as the inflation risk premium has effectively
been extinguished from the bond market. As short-term interest rates approach
zero, investors, savers, retirees, pension funds, foundations and endowments,
and a host of financial managers are at a loss to find appropriate means to
fulfill both long-term and short-term obligations. For example, a recent survey
by Morgan Stanley Research found that nearly 90% of the 292 S&P 500 component
companies they surveyed have annual return expectations of 8% or more for their
pension fund assets. These obligations simply cannot be satisfied through U.S.
Treasury or investment grade corporate debt securities whose coupons are far
below this minimum return expectation. The experience of the equity markets over
the past several years has served to rein in exposure to the volatility and low
current income of stocks in general. Ironically, despite this aversion to the
risk of equity markets, there has been a marked shift towards alternative and
riskier investments, including high yield bonds, commodities, foreign
securities, hedge funds and other vehicles, a trend that, frankly, we have
difficulty figuring out.

    In today's market environment, many investors are finding REITs to be a very
appealing asset class. Offering the potential for high income, tangible
underlying asset value, low correlation to other assets and long-term growth,
REITs are becoming increasingly more appreciated by investors. Further, we
believe that the prudent use of leverage -- which is plentiful today at a modern
record low cost -- by real estate owners and investors has helped real estate
prices have remained firm despite weak fundamentals. Moreover, in our view, it
explains why REITs are trading closer to some analysts' net asset value
estimates than might otherwise be expected.

    The entire notion of net asset value is subject to considerable debate. It
is our opinion that many analysts are underestimating REIT NAVs because they are
ignoring three important variables. First, the capitalization rate used to value
current rental streams and the discount rate used to value future rental streams
are at a low point in history, suggesting that higher valuations are warranted.
Second is the replacement cost of REIT assets. From Class A downtown office
buildings to dominant regional malls, the cost to replace these
assets -- assuming that one could at all -- far exceeds most current value
estimates of such properties. And third, since we believe we are just beginning
new economic and real estate growth cycles, investors should consider the
potential for real assets to appreciate as economic conditions improve. With
little or no speculative building taking place, except in the apartment sector,
it is unlikely that there will be a glut of new space coming on to the market
just as demand is increasing. This should necessarily precipitate an increase in
occupancy rates, rents and asset values.

    In our view, the key to continued positive returns from REITs is the future
course of the U.S. economy. As mentioned, signs of a recovery are beginning to
emerge. In light of the massive fiscal and monetary stimulus currently in place,
we are confident that in the coming quarters the economy will demonstrate
increasing strength.

    With respect to strategy, we are encouraged that our office sector holdings
are beginning to produce positive results. In our opinion, we are early in this
cycle and are making few changes except with respect to some individual
holdings. We believe that regional malls, the stars of the REIT industry over
the past three years, are likely to show the strongest earnings growth and
therefore remain a slight overweight position. We continue to maintain a
well-below market position in the shopping center sector, based on our belief
that this sector is currently trading at the greatest premium to net asset value
in our universe. Additionally, we remain underweight in the apartment sector,
due to low demand created by ongoing incentives for, and the unparalleled
attractiveness of, single-family home ownership.

    In light of the continued bull market for bonds, which only seemed to
accelerate during the second quarter, some comments regarding our thoughts on
REIT preferred stocks are in order. The good news for REITs is that

- --------------------------------------------------------------------------------

strength in the bond market and demand generated by significant capital entering
the market have presented very attractively priced opportunities. Many companies
have taken advantage by issuing new preferreds, with proceeds being used to
redeem higher-priced existing preferreds and for other corporate purposes.
However, these factors have made REIT preferred stocks less attractive. As a
result, we marginally reduced our allocation to REIT preferreds during the
quarter. Subsequent to quarter-end, we have observed a reversal in the strength
of the bond market, and will look to take advantage if REIT preferred pricing
adjusts accordingly.

    When any sector performs as well as -- and for as long as -- REITs have, an
abundance of skeptics invariably appear, both among industry analysts as well as
outside observers. We remain firm in our belief that we are at the beginning of
a new cycle and that real estate owners are entering the new cycle in a very
strong position. Further, we are not inclined to be market timers because we
have not seen any timing strategies that have been consistently successful. We
are confident that REITs will continue to play an important role in investors'
portfolio needs.

Sincerely,

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1. SIGNIFICANT ACCOUNTING POLICIES

    Cohen & Steers Advantage Income Realty Fund, Inc. (the fund) was
incorporated under the laws of the State of Maryland on June 21, 2000 and is
registered under the Investment Company Act of 1940, as amended, as a
nondiversified, closed-end management investment company.

    The following is a summary of significant accounting policies consistently
followed by the fund in the preparation of its financial statements. The
policies are in conformity with accounting principles generally accepted in the
United States of America. The preparation of the financial statements in
accordance 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
income and expenses during the reporting period. Actual results could differ
from those estimates.

    Portfolio Valuation: Investments in securities that are listed on the New
York Stock Exchange are valued, except as indicated below, at the last sale
price reflected at the close of the New York Stock Exchange on the business day
as of which such value is being determined. If there has been no sale on such
day, the securities are valued at the mean of the closing bid and asked prices
for the day. If no bid or asked prices are quoted on such day, then the security
is valued by such method as the board of directors shall determine in good faith
to reflect its fair market value.

    Securities not listed on the New York Stock Exchange but listed on other
domestic or foreign securities exchanges or admitted to trading on the National
Association of Securities Dealers Automated Quotations, Inc. (Nasdaq) national
market system are valued in a similar manner. Securities traded on more than one
securities exchange are valued at the last sale price on the business day as of
which such value is being determined as reflected on the tape at the close of
the exchange representing the principal market for such securities.

    Readily marketable securities traded in the over-the-counter market,
including listed securities whose primary market is believed by the investment
manager to be over-the-counter, but excluding securities admitted to trading on
the Nasdaq National List, are valued at the official closing prices as reported
by Nasdaq, the National Quotations Bureau or such other comparable sources as
the board of directors deems appropriate to reflect their fair market value.
However, certain fixed-income securities may be valued on the basis of prices
provided by a pricing service when such prices are believed by the board of
directors to reflect the fair market value of such securities. Where securities
are traded on more than one exchange and also over-the-counter, the securities
will generally be valued using the quotations the board of directors believes
reflect most closely the value of such securities.

    Short-term debt securities, which have a maturity of 60 days or less, are
valued at amortized cost which approximates value.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

    Interest Rate Swaps: The fund uses interest rate swaps in connection with
the leverage created by the sale of auction rate cumulative preferred shares.
The interest rate swaps are intended to reduce or eliminate the risk that an
increase in short-term interest rates could have on the performance of the
fund's common shares as a result of the floating rate nature of leverage. In an
interest rate swap, the fund agrees to pay the other party to the interest rate
swap (which is known as the counterparty) a fixed rate payment in exchange for
the counterparty agreeing to pay the fund a variable rate payment that is
intended to approximate the fund's variable rate payment obligation on the
auction rate cumulative preferred shares. The payment obligation is based on the
notional amount of the swap. Depending on the state of interest rates in
general, the use of interest rate swaps could enhance or harm the overall
performance of the common shares. The market value of interest rate swaps is
based on pricing models that consider the time value of money, volatility, the
current market and contractual prices of the underlying financial instrument.

    Revision of Financial Information: As required, effective January 1, 2003,
the fund has adopted the requirements of EITF Issue 02-3, Issues Involved in
Accounting for Derivative Contracts Held for Trading Purposes and Contracts
Involved in Energy Trading and Risk Management Activities, which requires that
periodic payments under interest rate swap transactions be reported as a
component of realized and unrealized gains/losses on the fund's statement of
operations. The fund has reclassified amounts previously reported as interest
expense on interest rate swap transactions, thereby revising certain amounts in
the Statement of Changes in Net Assets and the Financial Highlights. For the
year ended December 31, 2002, net investment income was increased by $3,614,482
($0.14 per share), and net realized loss on investments and interest rate swap
transactions and net change in unrealized depreciation on investments and
interest rate swap transactions were increased by $3,576,785 and $37,697,
respectively (a total of $0.14 per share). Additionally, for the period ended
December 31, 2001, net investment income per share was increased by $0.05 and
net realized and unrealized gain/(loss) on investments per share was increased
by $0.05.

    Additionally, the ratios of net investment income to average daily net
assets applicable to common shares (before expense reduction and net of expense
reduction) increased 1.00% and 0.54% for the year ended December 31, 2002 and
the period ended December 31, 2001, respectively; the ratios of expenses to
average daily net assets applicable to common shares (before expense reduction
and net of expense reduction) decreased 1.00% and 0.54% for the year ended
December 31, 2002 and the period ended December 31, 2001, respectively; and the
ratios of expenses to average daily managed assets (before expense reduction and
net of expense reduction) decreased 0.74% and 0.42% for the year ended December
31, 2002 and for the period ended December 31, 2001, respectively. The
reclassifications had no effect on net assets or on the net increase in net
assets from operations applicable to common shares.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

    Security Transactions and Investment Income: Security transactions are
recorded on trade date. Realized gains and losses on investments sold are
recorded on the basis of identified cost for accounting and tax purposes.
Interest income is recorded on the accrual basis. Dividend income is recorded on
the ex-dividend date. Discounts and premiums of securities purchased are
amortized using the scientific method over their respective lives.

    Dividends and Distributions to Shareholders: Dividends from net investment
income are declared and paid to common shareholders monthly. Distributions to
shareholders are recorded on the ex-dividend date. A portion of the fund's
dividend may consist of amounts in excess of net investment income derived from
nontaxable components of the dividends from the fund's portfolio investments.
Net realized capital gains, unless offset by any available capital loss
carryforward, are distributed to shareholders annually.

    Dividends from net investment income and capital gain distributions are
determined in accordance with U.S. federal income tax regulations which may
differ from generally accepted accounting principles.

    Preferred shares pay dividends based on a variable interest rate set at
auctions, normally held every seven days. Dividends for preferred shares are
accrued for the subsequent seven day period on the auction date. In most
instances, dividends are payable every seven days, on the first business day
following the end of the dividend period.

    Federal Income Taxes: It is the policy of the fund to qualify as a regulated
investment company, if such qualification is in the best interest of the
shareholders, by complying with the requirements of Subchapter M of the Internal
Revenue Code applicable to regulated investment companies, and by distributing
substantially all of its taxable earnings to its shareholders. Accordingly, no
provision for federal income or excise tax is necessary.

NOTE 2. INVESTMENT MANAGEMENT FEES, ADMINISTRATION FEES AND OTHER TRANSACTIONS
        WITH AFFILIATES.

    Investment Management Fees: Cohen & Steers Capital Management, Inc. (the
investment manager) serves as the investment manager to the fund, pursuant to an
investment management agreement (the management agreement). The investment
manager furnishes a continuous investment program for the fund's portfolio,
makes the day-to-day investment decisions for the fund and generally manages the
fund's investments in accordance with the stated polices of the fund, subject to
the general supervision of the board of directors of the fund.

    For the services under the management agreement, the fund pays the
investment manager a management fee, computed daily and paid monthly at an
annual rate of 0.85% of the fund's average daily managed asset value. Managed
asset value is the net asset value of the common shares plus the liquidation
preference of the preferred shares. For the six months ended June 30, 2003, the
fund incurred investment management fees of $2,242,579.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

    The investment manager has contractually agreed to waive its investment
management fee in the amount of 0.42% of average daily managed asset value for
the first five fiscal years of the fund's operations, 0.35% of average daily
managed asset value in year six, 0.28% of average daily managed asset value in
year seven, 0.21% of average daily managed asset value in year eight, 0.14% of
average daily managed asset value in year nine and 0.07% of average daily
managed asset value in year 10. As long as this expense cap continues, it may
lower the fund's expenses and increase its total return. For the six months
ended June 30, 2003, the investment manager waived management fees of
$1,108,098.

    Administration Fees: Pursuant to an administration agreement, the investment
manager also performs certain administrative and accounting functions for the
fund and receives a fee of 0.02% of the fund's average daily managed asset
value. For the six months ended June 30, 2003, the fund incurred $52,767 in
administration fees.

    Director's Fees: Certain directors and officers of the fund are also
directors, officers and/or employees of the investment manager. None of the
directors and officers so affiliated received compensation from the fund for
their services. Fees and related expenses accrued for nonaffiliated directors
totaled $21,785 for the six months ended June 30, 2003.

NOTE 3. PURCHASES AND SALES OF SECURITIES

    Purchases and sales of securities, excluding short-term investments, for the
six months ended June 30, 2003, totaled $66,610,747 and $65,608,096,

differences are permanent in nature, such amounts are reclassified within the
capital accounts. Short-term capital gains are reflected in the financial
statements as realized gains on investments but are typically reclassified as
ordinary income for tax purposes.

NOTE 5. CAPITAL STOCK

    The fund is authorized to issue 100 million shares of common stock at a par
value of $0.001 per share.

    During the six months ended June 30, 2003 the fund issued 187,613 shares of
common stock for the reinvestment of dividends.

    During the year ended December 31, 2002, the fund issued 462,456 shares of
common stock for the reinvestment of dividends.

    On December 13, 2002, the fund issued 2,040 auction rate cumulative
preferred shares, Series TH (par value $0.001). Proceeds paid to the fund
amounted to $50,214,908 after deduction of underwriting commissions and offering
expenses of $785,092. This issue has received a 'AAA/Aaa' rating from Standard &
Poor's and Moody's.

    The fund's articles of incorporation authorize the issuance of an unlimited
number of fund preferred shares, par value $0.001 per share, in one or more
classes or series, with rights as determined by the board of directors, by
action of the board of directors without the approval of the common
shareholders.

    Preferred shares are senior to the fund's common shares and will rank on a
parity with shares of any other series of preferred shares, and with shares of
any other series of preferred stock of the fund, as to the payment of dividends
and the distribution of assets upon liquidation. If the fund does not timely
cure a failure to (1) maintain a discounted value of its portfolio equal to the
preferred shares basic maintenance amount, as required by the fund's articles
supplementary for preferred shares (2) maintain the 1940 Act preferred shares
asset coverage, or (3) file a required certificate related to asset coverage on
time, the preferred shares will be subject to a mandatory redemption at the
redemption price of $25,000 per share plus an amount equal to accumulated but
unpaid dividends thereon to the date fixed for redemption. To the extent
permitted under the 1940 Act and Maryland law, the fund at its option may
without consent of the holders of preferred shares, redeem preferred shares
having a dividend period of one year or less, in whole, or in part, on the
business day after the last day of such dividend period upon not less than 15
calendar days and not more than 40 calendar days prior to notice. The optional
redemption price is $25,000 per share plus an amount equal to accumulated but
unpaid dividends thereon to the date fixed for redemption.

    The fund's common shares and preferred shares have equal voting rights of
one vote per share and vote together as a single class. In addition, the
affirmative vote of the holders of a majority, as defined in the 1940 Act,

of the outstanding preferred shares shall be required to (1) approve any plan of
reorganization that would adversely affect the auction rate cumulative preferred
shares and (2) any matter that materially and adversely affects the rights,
preferences, or powers of that series.

NOTE 6. INVESTMENTS IN INTEREST RATE SWAPS

    The fund has entered into five interest rate swap agreements with Salomon
Swapco Inc. Under the agreements the fund receives a floating rate of interest

         ---------------------------------------------------------------
           The fund is committed to maintaining the privacy of its
           shareholders and to safeguarding their personal information.
           The following is provided to help you understand what

           The fund does not receive any personal information relating
           to shareholders who purchase shares through an intermediary
           that acts as the record owner of the shares. In the case of
           shareholders who are record owners of the fund, to conduct
           and process your business in an accurate and efficient
           manner, we must collect and maintain certain personal
           information about you. This is the information we collect on
           applications or other forms, and from the transactions you

           its shareholders or former shareholders to anyone, except as
           required or permitted by law or as is necessary to service
           shareholder accounts. We will share information with
           organizations, such as the fund's transfer agent, that
           assist the fund in carrying out its daily business
           operations. These organizations will use this information
           only for purposes of providing the services required or as
           otherwise as may be required by law. These organizations are
           not permitted to share or use this information for any other
           purpose. In addition, the fund restricts access to personal
           information about its shareholders to employees of the
           investment manager who have a legitimate business need for
           the information.
