October 2021 highlights

After a September jump in inventory, October brought a slowdown in Boston and the suburbs. 

  • Metro area condo listings returned to normal. The number of condos listed dropped 48% month over month after a huge leap in September. Because of the extra September inventory, sale-to-list price ratio stayed about flat while median days on market dropped 30% as buyers made quick decisions thanks to a wealth of options. 
  • Extra single family home inventory lowered sale prices in the city. The number of single family homes listed dropped 22% in October after leaping 150% in September. Those extra homes decreased competition as few buyers moved to purchase them. Sale-to-list price ratio dropped 3% month over month, days on market rose a whopping 70%, and median sale price fell 6%. 
  • Single family homes in the suburbs saw the lowest median sale price since February. Median sale price dropped 9% to $750,000 month over month, coming in 7% lower than in October 2020 and 47% lower than this year’s high of $1,100,000 in July. Meanwhile, the number of properties listed fell 22% month over month and the number pending jumped 24%.
