The U.S. housing market is cooling in some areas, raising concerns about affordability and competition for prospective homebuyers. According to an analysis from the Brookings Institution, large institutional investors own roughly 3% to 3.8% of the nation's single-family rental homes. The impact is more concentrated in specific regional markets, according to a report from the Government Accountability Office. The report also highlighted concerns about rent increases tied to institutional ownership. In response, lawmakers at both the federal and state levels have proposed legislation aimed at curbing institutional ownership of single-fameral homes, including the "Stop Wall Street Landlords Act" and the "HOP Act". New York has also implemented rules targeting some large institutional investor firms.
