The short answer
Washington Square is one Brookline market area, not one interchangeable housing market.
This guide recorded 57 MLS-reported residential closed sales across the 12 complete months shown below: 48 condominiums and 9 single-family homes. Compare property types separately, then verify address-specific building, transit, municipal, and school information before relying on it.

The evidence behind the answer

|---|---|---|---|---|
| Closed sales | 10 | 5 | Up 100.0% | Residential closing volume moved higher. |

Read the signals together
Use the measures as a set, not a one-number verdict
Closed-sale volume was up 100.0% year over year; median sale price was up 45.9% year over year; average sale price was up 35.1% year over year; average price per square foot was up 5.2% year over year; and average marketing time was down 24.5% year over year.
These measures answer different questions and should not be collapsed into a simple “market up” or “market down” conclusion. Property type, size, condition, parking, outdoor space, and building characteristics can change both the mix of sales and the relevant comparison set.

| Neighborhood | Closed sales | Average $ / sq. ft. | Average DOM | Average sale-to-list |
|---|---|---|---|---|
| Washington Square Subject | 10 | $831 | 42.9 | 99.5% |
| Coolidge Corner | 15 | $904 | 34.3 | 100.3% |

| Pill Hill | 7 | $656 | 78.0 | 94.4% |
Property-level implications
How to use the monthly evidence
August 2026’s faster average pace and 99.5% average sale-to-list ratio support precise, property-specific pricing. The higher closing count makes the quality of the comparable-sale set especially important.
Higher closed-sale volume did not by itself establish negotiating leverage. Compare the home with similar properties and buildings, then weigh its condition, parking, outdoor space, and other property-specific features.
What the next report should confirm
Three signals to monitor without forecasting
- How does closed-sale volume compare with the same month a year earlier?
- How does average price per square foot compare with its prior-year level?
- Do marketing time and sale-to-list results stay consistent with August 2026?

Neighborhood due diligence
The market evidence sits inside an address-specific decision.
Washington Square is a useful market-area label, but it does not replace verification for a particular home or building.
Housing
The observed sample includes 48 condominium and 9 single-family closings. Building condition, association records, parking, outdoor space, and property condition can materially change the relevant comparison set.
Location & access
Confirm the exact route, current transit service, parking rules, and daily travel needs for the address you are considering. A neighborhood name is not a substitute for address-level review.
Schools
Neighborhood labels do not determine enrollment. Confirm the exact address and current assignment rules directly with Public Schools of Brookline.

Washington Square market FAQs
What period do the Washington Square market statistics cover?
The current page summarizes Sep 2025 – Aug 2026, with verified data through August 31, 2026. The reporting window advances only after the completed monthly data passes the Market Intelligence validation checks.
How is the Washington Square market area defined?
The page uses the neighborhood classification stored with the MLS-reported residential records in the Bushari Market Intelligence warehouse. It is a market-context area, not a legal, postal, or school-assignment boundary.
Do these neighborhood statistics establish the value of a specific home?
No. The figures describe the included market cohort. A property-specific analysis must also account for property type, size, condition, parking, outdoor space, building characteristics, and current competition.
How should school assignment be checked for a Washington Square address?
Verify the exact address directly with Public Schools of Brookline. Neighborhood names and real-estate market classifications do not determine enrollment.
