Nearly 10% more single-family homes in Massachusetts were sold last month than a year prior, but the expanded inventory came with a median sale price that jump up by more than 6% to hit a new all-time high for January.

The Warren Group reported Tuesday that the 2,626 single-family homes sold here in January represented a 9.3% increase over January 2024’s 2,403 single-family home transactions. The median single-family home price increased 6.4% year-over-year to hit $585,000, a new record high for the month.

Among the mainland Massachusetts counties, Berkshire County saw the greatest growth in January sales. The 97 homes sold there last month marked a 29.3% increase over the 75 sales in January 2024. Barnstable County was a close second, with 212 January sales representing a 26.9% increase over January 2024, according to The Warren Group.

State merges economic agencies

The 19 employees of the Massachusetts Growth Capital Corporation have folded into MassDevelopment as part of a legislatively-mandated merger.

The Executive Office of Economic Development said Tuesday that it has completed the merger of the two quasi-public agencies “to create an enhanced agency that will empower small and large businesses and mission-driven organizations with a more robust set of economic development and financing tools.”

The merger was required under a November 2024 economic development law.

Effective Tuesday, MGCC will become the Growth Capital Division at MassDevelopment, and “all MGCC programs and products will remain available to the small businesses previously served by MGCC to ensure no interruption in services for MGCC customers and stakeholders.” The MGCC website will remain active until March 31, and then will transition to the MassDevelopment website.
