Sliders run 1–100 (50 is typical for Braintree). 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.
In-law / accessory unit	A single-family home in a district that allows single-family homes by right. 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 $5,356 a year (assessed $536,700 × $9.98 per $1,000). An estimate: exemptions and abatements change the actual bill.
Elevation	About 84 ft above sea level, higher than 30% of Braintree homes.
Nearest expressway	About 1,240 ft from Route 3.
Nearest rail line	About 2,390 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.

Flood zone & environment

FEMA flood zone: X (minimal). Not in a mapped flood zone, so a lender won't require flood insurance.
Mapped wetland about 375 ft away. Outside the 100-ft wetland buffer zone.
Public sewer area. Inside the Braintree Water & Sewer service area, so no Title 5 septic inspection to sell.

Mapped at the parcel's center point from FEMA's flood maps, MassDEP, NHESP and MEMA (via MassGIS). Not a survey or a flood determination: confirm with FEMA's map service or a lender before you rely on it.
