Wicked Local Looking to buy a single-family home in Brookline? You’ll likely need a few things: A good realtor, quick instincts and at least $1 million lined up in financing. In 2020, 136 single-family property sales closed in town, according to data provided by the Massachusetts Association of Realtors. Only 11 of those homes sold for under $1 million, per the MLS Property Information Network for Massachusetts. The average sale price for homes listed under $1 million was $942,518 – about $50,000 above average listing price. Recently, greater Boston has seen a cutthroat seller’s market emerge as the result of low housing inventory and high buyer demand. But for already competitive markets like Brookline, those trends have only underscored existing market conditions.
