Single-family home sales saw a whopping year-over-year increase of 23.7% in September, according to the Massachusetts Association of Realtors.

The median price was up 19.5% to $490,000, while condo prices were up 10.5% to $420,000.

The association noted that a “shortage of inventory continues to foster a competitive bidding market with fast closing times and multiple offers for properties.

The number of homes on the market dropped by more than half (56.6%) of September 2019 numbers, and condo inventory was down 17.6%.

“While September is typically the ‘start’ of the fall market after the summer market winds down, this year we did not experience the typical summer slowdown,” Kurt Thompson, 2020 MAR President and a broker at Keller Williams Realty North Central in Leominster, said. “Despite some uncertainty due to the pandemic, we’re continuing to see many well-qualified and highly motivated buyers take advantage of historically low interest rates and continue to fuel a strong Massachusetts real estate market.”
