The Watertown market right now
Median prices and days on market cover closings from Jul–Sep 2026. Listing counts are as of Oct 7, 2026.
Supply and Demand: Watertown
Most Watertown sales are condos: 60 condo sales this quarter against 11 single-family homes. Condos sold at a median of $657,500, 98.8% of list, after 28 days.
Inventory held at 69 through July and August. In September, 61 homes came on, more than double August’s 27, while 28 went pending, so inventory rose to 113.
Even so, Watertown has 2.9 months of supply, a seller’s market. Single-family sales are thin, only 11 this quarter, so those numbers swing month to month, but they sold at a median of 105.1% of list in 19 days. Condo buyers have more room to negotiate than single-family buyers.

How to read it: New Listings counts homes listed that month. Total Active Inventory is everything on the market at the start of the month plus that month's new listings, so it counts every home a buyer could have seen that month. Went Pending counts homes that went under agreement, by offer date. Closed counts sales that recorded that month. All property types (single-family, condo and multi-family) are included.
Source: MLS Property Information Network, Inc. (MLS PIN), Middlesex County data as of Oct 7, 2026. Deemed reliable but not guaranteed. Jul closings start Jul 7, so they're a few days short. Listings that were withdrawn or expired aren't in the export, so earlier months slightly undercount new listings and inventory. The latest month's pending count will rise as recent listings go under agreement. Medians based on small numbers of sales can swing month to month.

As of Oct 7, 2026, Watertown has about 2.9 months of supply (89 active listings against roughly 31 closings a month over the last three months), which points to a seller's market.

Legally, a city. Watertown voted in 1980 to adopt a city form of government, which took effect in 1981. Its official name is “the City known as the Town of Watertown,” and it is run by an elected council and an appointed manager.
