Read the signals together

Use the measures as a set, not a one-number verdict

Closed-sale volume was unchanged year over year; median sale price was up 25.8% year over year; average sale price was up 25.1% year over year; average price per square foot was up 1.2% year over year; and average marketing time was down 1.5% 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.

Property-level implications

How to use the monthly evidence

Seller read

June 2026’s faster average pace and 100.4% average sale-to-list ratio support precise, property-specific pricing. The similar closing count makes the quality of the comparable-sale set especially important.

Buyer read

Similar 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 June 2026?

Washington Square market FAQs

What period do the Washington Square market statistics cover?

The current page summarizes Jul 2025 – Jun 2026, with verified data through June 30, 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.

Market Data Methodology

Market statistics on this page are based on MLS-reported residential sales in the Washington Square area for the period Jul 2025 – Jun 2026, including single-family homes and condominiums unless otherwise noted. Data are included only through June 30, 2026; the latest potentially incomplete month is excluded. Private, off-market, and non-MLS transactions may not be included. Neighborhood and school-zone boundaries are approximate and should be used for market context only — not for legal or school-assignment verification. School assignment and buffer-zone status should be verified directly with Public Schools of Brookline.

Year-over-year comparison: Jul 2025 – Jun 2026 (52 closed sales) compared with Jul 2024 – Jun 2025 (61 closed sales). Sale-to-list change is shown in percentage points.

Small-sample disclosure: September 2025 (3 closed sales); October 2025 (4 closed sales); December 2025 (1 closed sale); February 2026 (1 closed sale); April 2026 (4 closed sales). Monthly averages and medians are calculated from all valid observed transactions. Months with fewer than 5 closings are descriptive only and are excluded from directional conclusions and stable peer comparisons.
