The Acton, Massachusetts, single-family housing market shifted in July, as the supply increased and median prices decreased, even as sales activity held steady, according to data compiled by the Massachusetts Association of Realtors (MAR).
Inventory more than doubled in July, rising 121 percent to 31 listings, and the number of months of supply of inventory climbed to 2.1 months from 1.0 months, a 110 percent increase. The number of months of supply is a key metric for understanding the balance between supply and demand in the housing market. A market with approximately five to six months of inventory is considered balanced between home buyers and sellers.
Sellers still received nearly 103 percent of the original listing price, but down from 108 percent, indicating a significant cooling of the once highly competitive market.
Pending sales increased from 12 to 20 in July, and new listings doubled to 20 from 10.
From January through July, median prices fell, sales were steady, and homebuyers paid more than the original listing price.
The median price of a single-family home dropped 7 percent to $950,504 from $1,020,760 during the same seven-month period in 2024.
