Nov 4 (Reuters) - AvalonBay Communities ( AVB ) beat

estimates for third-quarter funds from operations on Monday, as

limited supply of rental apartments in suburban coastal markets

in the United States, relative to demand, boosted rental income.

AvalonBay's portfolio, including properties in states such

as New England and Florida, and metro areas like New York and

Washington, D.C., remains relatively insulated from heavy rental

supply elsewhere in the United States, resulting in steady rent

growth as demand remains robust.

The real estate investment trust (REIT) reported

third-quarter core FFO per share, a key profitability metric

watched closely by investors, of $2.74, surpassing analysts'

estimates of $2.72, according to LSEG data.

Same-store residential revenue grew 3.1% in the quarter

ended Sept. 30, with highest gains in New England and Pacific

Northwest regions.

The company also narrowed its full-year core FFO forecast

range to $10.99 to $11.09 per share, from $10.92 to $11.12.
