At 66 years old, one Sherman Oaks, California-based mom thought she’d be enjoying an empty nest with her husband. Instead, she’s sharing her home with an unexpected roommate: her 27-year-old daughter.

Since their 27-year-old moved back home in early 2024, the mother, who asked to remain anonymous to protect her daughter’s identity, says she and her husband are spending close to $5,000 a month covering all of her daughter’s living expenses. This includes up to $1,500 on food, $700 on transportation and $400 on her pet cat, the mother says.

Because of the increased expenses, she says they’re no longer going on vacation this year, and her husband, a radiologist, may have to delay retirement.

“We were not planning on this kind of expenditure at this point of our lives,” the mother says. “The reason we do it is because we don’t want to see her on the street.”

The couple join a growing number of parents who say their finances have been affected by children aged 18 to 35 moving back home. One survey published in May by financial services provider Thrivent found that nearly 40% of U.S. parents say supporting their adult children has impacted their savings goals — the highest percentage since the survey began four years ago.
