             ONE LIBERTY PROPERTIES ANNOUNCES RESULTS OF OPERATIONS
                      FOR THE QUARTER ENDED MARCH 31, 2006

Great Neck, New York - May 9, 2006 - One Liberty Properties, Inc. (NYSE: OLP)
today announced that for the three months ended March 31, 2006, rental income
increased by 11.9% and net income by 12.7%, compared to rental income and net
income for the three months ended March 31, 2005. The Company reported rental
income of $7,584,000 and net income of $3,070,000, or $.31 per common share on a
diluted basis, for the three months ended March 31, 2006. Net income for the
quarter ended March 31, 2006 gives effect to the Company's equity in earnings of
unconsolidated joint ventures of $774,000, or $.08 per diluted share, and gain
on sale of an option to purchase property of $227,000, or $.02 per diluted
share. This compares with rental income of $6,777,000, net income of $2,723,000
and net income per common share, on a diluted basis of $.28 per share, for the
three months ended March 31, 2005. Net income for the three months ended March
31, 2005 gives effect to the Company's equity in earnings of unconsolidated
joint ventures of $1,108,000, or $.11 per diluted share, and loss from
discontinued operations of $137,000 or $.01 per share. The weighted average
number of common shares outstanding on a diluted basis was 9,897,000 and
9,802,000 for the three months ended March 31, 2006 and 2005, respectively.

One Liberty also reported funds from operations of $4,953,000, or $.50 per
common share on a diluted basis, for the three months ended March 31, 2006, as
compared to $4,521,000, or $.46 per diluted share, for the three months ended
March 31, 2005. Funds from operations calculated in accordance with the NAREIT
definition, adds back to net income depreciation of properties, One Liberty's
share of depreciation in unconsolidated joint ventures and amortization of
capitalized leasing expenses.

Commenting on the results of operations, Fredric H. Gould, Chairman of the Board
and Chief Executive Officer of One Liberty stated that "the increase in our
rental income quarter over quarter was primarily due to the acquisition of eight
properties at various times in 2005". Mr. Gould noted that operating expenses
increased by 17.2% quarter versus quarter. A 16.1% increase in depreciation
expense quarter over quarter is directly related to the increase in the number
of properties owned by the Company. General and administrative expenses
increased by 26.6% quarter versus quarter due to a number of factors, including
an increase in directors' fees, an increase in payroll expense and allocated
expenses due primarily to increased operations, fees of special counsel retained
by the Company's Audit Committee, and an increase in the expense related to the
issuance of restricted stock.

Commenting further, Mr. Gould noted that negatively impacting the Company's net
income in the current quarter as compared to the quarter ending March 31, 2005
was a 30.1% decrease in the Company's equity in earnings of unconsolidated
ventures. The decrease was primarily due to the receipt in the three months
ended March 31, 2005 of rent arrearages by one of the Company's joint ventures
and interest expense incurred in the 2006 quarter on a mortgage placed by a
joint venture in 2005. Also impacting the Company's expenses quarter versus
quarter, is an increase in interest expense due to mortgage loans placed by the
Company on acquired properties, offset by a decrease in the interest expense
incurred in the 2006 quarter under the Company's credit line. Indebtedness under
the credit line was repaid in full in 2005 from the proceeds derived by the
Company from mortgage financings. Also positively impacting net income in the
current quarter was interest income received on the investment of the proceeds
derived from a mortgage financing and a gain recognized on the sale of an option
which the Company held to purchase a parcel of real property adjacent to one of
its properties.

In 2005 the Company sold five properties. The operations of these five
properties are reflected in the March 31, 2005 quarterly results as a loss from
discontinued operations. These five properties did not have any impact on the
March 31, 2006 quarterly results.

One Liberty Properties is a real estate investment trust and invests primarily
in improved commercial real estate under long term net lease.

(a) We believe that FFO is a useful and a standard  supplemental  measure of the
operating  performance  for equity REITs and is used  frequently  by  securities
analysts,  investors and other  interested  parties in evaluating  equity REITs,
many of which  present  FFO  when  reporting  their  operating  results.  FFO is
intended to exclude GAAP historical cost  depreciation  and amortization of real
estate  assets,  which  assures  that the value of real estate  assets  diminish
predictability  over time. In fact, real estate values have  historically  risen
and fallen with market  conditions.  As a result, we believe that FFO provides a
performance measure that when compared year over year, should reflect the impact
to operations from trends in occupancy  rates,  rental rates,  operating  costs,
interest  costs and other  matters  without the  inclusion of  depreciation  and
amortization,  providing a perspective that may not be necessarily apparent from
net income.  We also  consider  FFO to be useful to us in  evaluating  potential
property acquisitions.

FFO does not  represent  net income or cash flows from  operations as defined by
GAAP.  You  should  not  consider  FFO to be an  alternative  to net income as a
reliable measure of our operating performance; nor should you consider FFO to be
an alternative to cash flows from operating,  investing or financing  activities
(as defined by GAAP) as measures of liquidity.

FFO does not measure  whether  cash flow is  sufficient  to fund all of our cash
needs, including principal amortization,  capital improvements and distributions
to stockholders.  FFO does not represent cash flows from operating, investing or
financing activities as defined by GAAP.
