As Airbnb continues to increase its New York footprint, a new study estimates the city is on track to lose over a thousand housing units to the short-term rental market over the next year… That adds to the 9,000 housing units the report says have already become unavailable since the company began operating in New York. Meanwhile, the company’s growth will spur $8.6 million in rent increases for New Yorkers looking for apartments, the study said.
