                         ANNOUNCES RESULTS OF OPERATIONS
                      FOR THE QUARTER ENDED MARCH 31, 2005

Great Neck, New York - May 9, 2005 - One Liberty Properties, Inc. (NYSE: OLP)
today announced it had revenues for the three months ended March 31, 2005 (the
first quarter of its fiscal year) of $7,126,000 and net income of $2,723,000, or
$.28 per share on a diluted basis. Net income for the three months ended March
31, 2005 gives effect to One Liberty's equity in earnings of unconsolidated
joint ventures of $1,108,000. For the three months ended March 31, 2004, One
Liberty reported revenues of $5,650,000 and net income of $2,245,000, or $.23
per share on a diluted basis. Net income for the three months ended March 31,
2004 gives effect to One Liberty's equity in earnings of unconsolidated joint
ventures of $675,000. The weighted average number of common shares outstanding
on a diluted basis was 9,802,000 and 9,688,000 for the three months ended March
31, 2005 and March 31, 2004, respectively.

One Liberty also reported that funds from operations for the three months ended
March 31, 2005 was $4,521,000, or $.46 per share on a diluted basis, compared to
$3,533,000, or $.37 per share on a diluted basis, for the three months ended
March 31, 2004. 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 and the funds from operations, Jeffrey
Fishman, President and Chief Executive Officer of One Liberty, noted that
revenues, substantially all of which represents rental income, increased by
$1,476,000, or 26%, due primarily to rental revenues earned on twelve properties
acquired by One Liberty between March 2004 and February 2005. Mr. Fishman noted
that One Liberty's equity in earnings of joint ventures increased by $433,000,
or 64%, of which $296,000 resulted from payment of rent arrears to one of our
movie theater joint ventures. On the expense side, total expenses increased by
$1,430,000, or 35%, quarter over quarter, as a result of an increase in
depreciation and amortization due to the ownership of additional properties, an
increase in interest on mortgages payable as a result of the origination of
three mortgages, the assumption of mortgages in connection with the purchase of
two properties and penalties incurred in connection with the prepayment of two
mortgages which had above market interest rates, and an increase in interest on
our line of credit in connection with the purchase of several properties.
Commenting further, Mr. Fishman noted that real estate expenses increased by
$182,000, quarter over quarter, of which $160,000 was primarily due to real
estate operating expenses incurred with respect to one property.

In reviewing the results of operations, Mr. Fishman commented that One Liberty
purchased six properties for a total consideration of approximately $24,700,000
in two transactions that closed in January 2005 and February 2005, respectively,
and that since these transactions closed during this quarter, operation of these
properties should have a greater impact on One Liberty's net income and funds
from operations in the June 30, 2005 quarter and following periods than it had
in this quarter.

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