CHAIRMAN'S LETTER


Dear Shareholder,

I am pleased to present to you this annual report for Neuberger Berman Real
Estate Securities Income Fund Inc. for the fiscal year ended October 31, 2007.
The report includes portfolio commentary, a listing of the Fund's investments,
and its audited financial statements for the reporting period. In addition, I am
taking this opportunity to highlight several significant initiatives taken by
the Fund's Board of Directors during the fiscal year.

o    In the first half of calendar 2007, the Fund amended its application for
     exemptive relief from the Securities and Exchange Commission to allow it to
     implement a "managed distribution plan." This plan would permit the Fund to
     distribute long-term capital gains to shareholders more frequently than is
     otherwise permitted by law. The Board believes that a managed distribution
     plan may help the Fund attract new investors, support the market price of
     its common stock, and help narrow the discount at which the Fund's common
     stock trades.

o    In April 2007, the Board authorized an increase in the amount of the Fund's
     monthly distribution to $0.15308 per share from $0.10, effective with the
     May distribution.

o    In October 2007, the Board approved a proposal to merge Neuberger Berman
     Realty Income Fund Inc. (NYSE: NRI) into the Fund, pending shareholder
     approval. If approved, the transaction will result in one of the largest
     domestic real estate closed-end funds and should eliminate confusion in the
     market place. The Board believes that the larger merged fund may provide
     shareholders benefits such as enhanced liquidity, reduced expenses and
     overall a lower expense ratio. Although there can be no assurances, the
     Board also believes that the transaction could have the positive effect of
     narrowing the discount from net asset value at which the Fund's common
     stock trades.

These actions are consistent with the Board's proactive posture -- one focused
on continually seeking actions that it believes are in the best interests of the
Fund's shareholders.

Thank you for your confidence in Neuberger Berman.  We will continue to do our
best to earn it.

Sincerely,


/s/ Peter Sundman

CHAIRMAN OF THE BOARD
NEUBERGER BERMAN REAL ESTATE SECURITIES INCOME FUND INC.
