Heat compares the last 12 months' days to offer and sale-to-asking with every year since 2016 (100 = the hottest it has been). From MLS PIN closed sales in Braintree; condos and single-family homes only.

Scores run 1–100; 50 is typical. Prices are placed among Braintree MLS PIN closed sales of the same year, so an older sale is judged against the prices of its own time. A past or asking price only: we don't estimate what any home is worth. Scores describe how the market behaves, not the home or its neighbors.

Zoning, taxes & the land

Zoning	Residence B (B). Confirm with the town before you plan around it.

Under the 2025 state ADU law, one accessory dwelling up to 900 sq ft (or half the house, if smaller) is generally allowed here without a special permit. Site rules like setbacks and parking still apply.
Property tax, FY2025	About $9,585 a year (assessed $960,400 × $9.98 per $1,000). An estimate: exemptions and abatements change the actual bill.
Elevation	About 121 ft above sea level, higher than 62% of Braintree homes.
Nearest expressway	About 2,450 ft from Route 3.
Nearest rail line	About 990 ft from the Kingston commuter rail line.

Zoning from MassGIS tax parcels; elevation from state LiDAR at the parcel's center point; distances are straight-line. Tax uses the town's residential rate for that fiscal year.
