             ONE LIBERTY PROPERTIES ANNOUNCES RESULTS OF OPERATIONS
                    FOR THE FIRST QUARTER OF ITS FISCAL YEAR

Great Neck, New York - May 10, 2004 - One Liberty Properties, Inc. (NYSE: OLP)
today announced that for the three months ended March 31, 2004 it had revenues
of $5,650,000 and net income applicable to common stockholders of $2,245,000, or
$.23 per share on a diluted basis. Net income gives effect to the Company's
equity in earnings of unconsolidated joint ventures of $675,000. For the quarter
ended March 31, 2003, One Liberty reported revenues of $4,644,000 and net income
applicable to common stockholders of $1,939,000, or $.34 per share on a diluted
basis. Net income for the quarter ended March 31, 2003 gives effect to the
Company's equity in earnings of unconsolidated joint ventures of $654,000. The
weighted average number of common shares outstanding on a diluted basis was
9,669,000 and 5,667,000 for the three months ended March 31, 2004 and March 31,
2003, respectively.

One Liberty also reported that funds from operations applicable to common
stockholders for the three months ended March 31, 2004 was $3,533,000, or $.37
per share on a diluted basis, as compared to $2,890,000, or $.51 per share on a
diluted basis, for the three months ended March 31, 2003. 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
and deducts cash distributions paid to preferred stockholders. The Company
redeemed all of its outstanding preferred stock on December 30, 2003.

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
$1,006,000, or 22%, due to rental revenues earned on seven properties acquired
by the Company between February 2003 and March 2004. On the expense side, total
expenses increased by $981,000, or 32%, quarter over quarter, as a result of an
increase in depreciation and amortization due to the ownership of additional
properties and an increase in interest on mortgages payable as a result of the
origination of two mortgages, the assumption of mortgages in connection with the
purchase of four properties and the refinancing of one property. Commenting
further, Mr. Fishman noted that general and administrative expenses increased by
$315,000, or by 58%, quarter over quarter, of which $101,000 was due to a
"non-recurring" fee for the initial listing by the Company of its common stock
on the New York Stock Exchange in January 2004. Other general and administrative
expenses increased due to an increase in the level of the Company's business
activities, including activities related to property acquisitions, the
negotiation of an increase in the revolving credit facility, mortgage
refinancings, compliance with the Sarbanes-Oxley Act and with new accounting
pronouncements and an increase in professional fees, state taxes and travel.

In reviewing the quarterly results, Mr. Fishman commented that the Company
purchased two properties for a total consideration of approximately $23,100,000
in March, 2004, and that since these two property acquisitions were completed on
March 1st and March 31, 2004, respectively, operation of these properties will
have a greater impact on the Company's net income and funds from operations in
the June 30, 2004 quarter and in following periods. He further commented that
the Company has contracted to purchase in a single transaction two retail
properties, containing an aggregate of 41,280 square feet located in Athens,
Georgia, for a total consideration of $5,735,000. One property containing 20,000
square feet is leased to Office Depot under a lease which expires in 2014 and
the other property containing 21,280 square feet is leased to Michaels Arts and
Crafts under a lease which expires in 2014. The closing of the transaction is
expected to take place prior to the end of May. Mr. Fishman noted that at March
31, 2004, the Company had cash and cash equivalents of approximately
$29,000,000, substantially all of which will be used for property acquisitions.

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