September 2026 snapshot
Reading the market
September 2026 included 25 closed residential sales: 8 single-family and 17 condominium. 2 multifamily transactions and 125 rental leases were tracked separately and are not part of the townwide residential count. The residential median sale price was $1,275,000, compared with an average of $1,724,528. When reviewing average and median sale prices, the mix of property types closed in any given period shapes those figures as much as broader conditions do. A month heavy with condominiums will produce different averages than one dominated by single-family homes, even if individual values within each category are unchanged. Because Brookline tracks multifamily and rental properties separately from residential totals, the residential figures reflect a specific subset of activity. Comparing months without accounting for that composition can be misleading, so understanding what types of homes are included matters before drawing any conclusions.

What this means for you
For buyers
A monthly report captures only what closed during that particular period, so availability and pricing you encounter while actively searching may differ from what the report describes. To make meaningful comparisons, focus on homes that closely match your target in type, size, condition, and location rather than relying on overall averages. Always check current active listings and recent closings separately, since the market you are shopping in today is distinct from the one reflected in a report compiled from an earlier snapshot. Working through the details of comparable homes gives you a more grounded basis for evaluating any specific property.
Explore homes for sale →For sellers
Setting an asking price is most reliably grounded in closed sales of genuinely comparable properties, accounting for differences in size, condition, layout, lot, and specific location. Direct competition from currently active listings also matters, because buyers are making choices among available options simultaneously. Property differences can explain a wide range of outcomes between otherwise similar homes, and those differences deserve careful consideration before drawing conclusions. Days on market and any variation between list and sale price reflect many property-specific factors and should not be used in isolation to infer anything about pricing strategy or seller circumstances.
Plan your sale →Questions about this report
Which dates and property types does this report cover?
The reporting window is 2026-09-01 through 2026-10-01 (end exclusive). Data was extracted 2026-10-02. Residential totals include single-family and condominium closed sales. Multifamily transactions and rental leases are separate.
How many Brookline homes sold during the month?
25 residential sales closed: 8 single-family homes and 17 condominiums. Multifamily sales, tracked separately, totaled 2.
What were the median and average sale prices?
The residential median sold price was $1,275,000; the average was $1,724,528. The median is the middle recorded sale; the average is the total divided by the sale count. Different homes closing can change either measure without establishing like-for-like appreciation.
How did the recorded sales compare with asking prices?
12% closed above their recorded list price and 84% below. 52% of the closed-sale cohort had a recorded price reduction. These figures do not establish seller motivation, property condition or concessions.
How long were the sold homes on the market?
Median days on market was 71; the average was 80.1. Days on market describes marketing time, not the full contract-to-closing timeline. Individual properties can differ substantially.
What do inventory and months of supply show?
The packet reports 218 active residential listings and 8.7 months of supply for its period snapshot. The measure relates inventory to the source model’s sales pace; it is not a forecast or a live list of available homes.
What does the condominium segment show?
17 condos closed at a median of $1,040,000 and an average of $1,231,482. The median monthly condo fee was $776. Fees belong to the recorded sold cohort and vary by building and unit.
How should I use neighborhood figures?
Compare the mapped area rows alongside their sale counts and property mix. Fewer than five transactions is a small sample. Unmapped sales are not assigned to an area by this report, and a neighborhood median does not value an individual property.
Do school-area figures describe school quality or assignment?
No. These are housing-market observations grouped by the source packet’s recorded area labels. They do not rank schools or guarantee enrollment. Verify assignment for a particular address with Public Schools of Brookline.
What happened in the rental market?
125 rental leases were recorded, with a median monthly rent of $3,400 and an average of $3,812. Rental leases and rents are excluded from the residential home-sale totals.
How can a seller use this report?
Use the property-type, competition and neighborhood data to frame questions about recent comparable sales. Compare a specific home’s size, condition and direct competition. The report is market context, not an appraisal, a recommended asking price or a prediction of the outcome.
