NEW YORK — It’s not exactly “The Golden Girls,” but for Marcia Rosenfeld, it’ll do.

Rosenfeld is among thousands of aging Americans taking part in home-sharing programs around the country that allow seniors to stay in their homes and save money while getting some much-needed companionship.

“It’s a wonderful arrangement,” said the white-haired Rosenfeld, who when asked her age will only say she’s a senior citizen. “The way the rents are these days, I couldn’t stay here without it.”

She shares her two-bedroom, $1,000-a-month Brooklyn apartment with Carolyn Allen, a 69-year-old widow who has suffered two strokes and no longer wants to live alone.

Agencies who put such seniors together say the need appears to be growing as baby boomers age and struggle to deal with foreclosures, property taxes and rising rents. The typical situation involves an elderly woman, widowed or divorced, who has a house or an apartment with extra room and needs help with the upkeep.
