Andover's housing market stayed competitive in July 2025, with prices up and supply tighter even as sales cooled, according to data compiled by the Massachusetts Association of Realtors (MAR).
The single-family inventory fell to 39 homes on the market, a 20 percent decrease from 49 in July 2024. The number of months of supply declined to 1.6 months from 2.2 months.
Months of supply, also known as months of inventory, indicates how long it would take for all homes currently for sale to sell, assuming no new listings are added and the current sales pace remains consistent. 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 continued to capture, on average, strong prices in July at 103 percent of the original listing price, a slight easing from 104 percent in July 2024.
Pending sales rose to 37 in July, up 32 percent from 28, while new listings slipped by one to 25.
Through July, the single-family market in Andover showed steady activity and strength: the median price reached $1,112,500, up 4 percent from $1,070,000 during the same seven-month period in 2024; closed sales increased to 152, up 5 percent from 145; sellers received 103 percent of the original listing price, down modestly from 104 percent; and new listings rose to 222, up 3 percent from 215.
Condominiums posted a sharp price gain in July, according to MAR. The median condo price jumped to $491,000, a 32 percent increase from $370,000, based on the sale of only 10 units.
Condominium inventory increased by two units to 14, and the number of months of supply rose to 1.7 from 1.5, indicating a significant seller's market.
On average, sellers received approximately 102 percent of the original listing price in both July and July 2024.
Pending sales dipped by one to 10, while new listings held at 11 units.
From January through July, condos had strong demand despite higher price points.
The median condo price in July reached $490,650, up 28 percent from $382,000.
Closed sales climbed to 62, up almost 22 percent from 51 in July 2024.
Andover condominium buyers paid, on average, 101 percent of the original listing price through July, about the same as the January-July timeframe in 2024
The number of new listings increased to 86, up 16 percent from 74.
Bottom line: Andover's July data point to sustained seller leverage—especially on price—amid lean single-family supply and rising condo values. Through July, condominiums exhibited increased market activity, while the single-family market demonstrated resiliency.
