Senior Apartments: what you're actually buying
Senior apartments are age-restricted rentals — some market-rate, some income-based — for older adults who are independent but want an age-friendly, lower-cost setting.
They are housing, not licensed care; some participate in HUD or Low-Income Housing Tax Credit programs with income limits and waitlists. A typical monthly range is $750 to $2,000 a month, less for income-based units.
The details that matter most rarely show up in the brochure:
- income limits and the length of any waitlist
- what accessibility features the units include
- whether services like meals or transportation are available
