New York City’s Airbnb clampdown has owners of one- and two-family homes claiming they are fighting to stave off foreclosure as income from their short-term rentals dries up, The Post has learned.

Since the new rule – known as Local Law 18 — went into effect in September, property owners’ housing costs have surged to more than 50% of their income, according to a study by a grassroots group representing single- and two-family homeowners that was presented to some members of the City Council this week.

The report by Restore Home Ownership Authority and Rights, or RHOAR — obtained exclusively by The Post — said the financial hit could put their members at risk of losing their homes at a time when home foreclosures citywide are up 44% from a year ago.
