April 30 (Reuters) - Real estate investment trust (REIT) Boston Properties cut its full-year forecast for funds from operations (FFO) on Tuesday, as high mortgage rates weighed down demand for office spaces.

The company now expects its full-year FFO to be between $6.98 and $7.10 per share, compared with a prior estimate of $7 to $7.20 per share. According to LSEG data, analysts, on average, expected it to be $7.12 per share.

Despite several companies issuing Return to office mandates, the commercial real estate market remains under pressure due to increased interest rates over the past couple of years.

Boston Properties, the largest publicly-traded developer of premier workplaces in the United States, reported FFO, a key measure of performance of a REIT, of $1.73 per share, meeting analyst estimates for the quarter ended March 31.

Its revenue rose 4.5% to $839.4 million in the quarter, beating analysts' average estimate of $808.6 million.

Net income attributable to Boston Properties rose to $79.9 million, or 51 cents per share, compared with $77.9 million, or 50 cents per share, a year earlier.

Shares of the company were down 3% in extended trading. (Reporting by Shivansh Tiwary and Abhinav Parmar in Bengaluru; Editing by Tasim Zahid)
