“It’s been a full year since COVID impacted the market. Since then, demand for housing has soared as more of us continue to work from home and find we need more space,” Kristen Jones, Broker/Owner of RE/MAX Around Atlanta said. “Meanwhile, inventory continues to decline, as many potential sellers have put their moving plans on hold.”

National housing inventory hit a new low for the ninth consecutive month and was down 45.2% year over year, while the average months supply of inventory also set a record, of 1.1 months. There was a 0.9 month supply of inventory in Boston.
