Apartment rents fell in every major metropolitan area in the U.S. over the past six months through January, a trend that is poised to continue as the biggest delivery of new apartments in nearly four decades is slated for this year, the Wall Street Journal reported. Renters with new leases in January paid a median rent that was 3.5% lower than they would have paid last August, according to estimates from listing website Apartment List. It was the first time in five years that rent fell every month over a six-month period, according to the same estimates. Four other market measures by housing-data companies also show that new-lease rents either fell or remained flat in January compared with the previous month, extending a streak of monthly rent declines that began at the end of the summer. The softening rental market follows an unprecedented run for the apartment and home-rental industry put into motion by the pandemic. Pent-up demand for housing exploded in the months after the introduction of COVID-19 vaccines in late 2020 and a surge in people searching for apartments lifted rents 25% over two years.
