The short answer
Coolidge Corner is one Brookline market area, not one interchangeable housing market.
This guide recorded 193 MLS-reported residential closed sales across the 12 complete months shown below: 180 condominiums and 13 single-family homes. Compare property types separately, then verify address-specific building, transit, municipal, and school information before relying on it.

|---|---|---|---|---|
| Closed sales | 7 | 24 | Down 70.8% | Residential closing volume moved lower. |

Read the signals together
Use the measures as a set, not a one-number verdict
Closed-sale volume was down 70.8% year over year; median sale price was up 5.8% year over year; average sale price was up 30.2% year over year; average price per square foot was up 2.0% year over year; and average marketing time was up 2.8% 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.
Same-month Brookline context
How Coolidge Corner compared with other stable September 2026 samples
Only Brookline neighborhoods with at least 5 MLS-reported residential closings are included. This is a context table, not a ranking.
| Neighborhood | Closed sales | Average $ / sq. ft. | Average DOM | Average sale-to-list |
|---|---|---|---|---|
| Coolidge Corner Subject | 7 | $853 | 44.7 | 100.4% |
| Washington Square | 5 | $951 | 62.0 | 94.7% |
Property-level implications
How to use the monthly evidence
September 2026’s slower average pace and 100.4% average sale-to-list ratio support precise, property-specific pricing. The lower closing count makes the quality of the comparable-sale set especially important.
Lower 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 September 2026?
Evidence window: September 1–30, 2026. Sample: 7 MLS-reported residential closed sales in Coolidge Corner. Comparison: September 2025 (24 closed sales). Prepared: October 2, 2026.

Neighborhood due diligence
The market evidence sits inside an address-specific decision.
Coolidge Corner is a useful market-area label, but it does not replace verification for a particular home or building.
Housing
The observed sample includes 180 condominium and 13 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.
Decision notes
What the evidence changes for buyers and sellers
For sellers
Build the comparison set before the price
Start with the closest comparable sales by property type, size, condition, parking, outdoor space, and building characteristics. For condominiums, the most useful comparison set is often within the same building or a small group of similar nearby buildings. Before setting a price or launch date, refresh the active and pending competition so the strategy reflects what buyers can choose at that moment.
Request a property-specific valuationFor buyers
Separate the home from the building risk
Compare condominiums and single-family homes separately, because their pricing and sample sizes differ substantially. For a condominium, review the association budget, reserves, recent meeting records, owner-occupancy information, and any planned assessments in addition to the unit itself. Confirm transit, municipal, and school-assignment details with the relevant official source for the exact address.

Coolidge Corner market FAQs
How current are the Coolidge Corner market statistics?
The reporting period and data-through date are shown at the top of the page. The automated Market Intelligence engine advances the page only to the latest complete monthly reporting cohort after its stored metrics pass validation; the methodology note also shows when the underlying warehouse last changed.
What do the average and median sale prices represent?
The average is the arithmetic mean of the MLS-reported closed sale prices in the stated segment and period; the median is the midpoint. Both describe the included transaction set and are not estimates of a specific property’s value.
Are school assignments guaranteed by the neighborhood name?
No. Brookline assignments can depend on the exact address and applicable attendance or buffer-zone rules. Verify an address directly with Public Schools of Brookline before relying on an assignment.
How is the Coolidge Corner market area defined?
The page uses the project’s Brookline neighborhood classification for market context. Neighborhood boundaries are approximate and are not legal, postal, or school-assignment boundaries.
