Scored against every street in Braintree.
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.
