Tract changes

Thirty years of the same lot

States and the USDA have photographed the land from the air again and again for decades. Your report lines those photographs up over the lot, so you can see when the garage went up, when the pool went in, and what used to stand there.

What's in the report

Everything the public record holds on one house

  1. 01

    Value history

    Every assessed value we hold, year by year, with the jumps explained where a permit or a town-wide revaluation accounts for them.

  2. 02

    Ownership and sales

    When the house changed hands, recorded sale prices, and transfers that happened without a sale.

  3. 03

    Building permits

    Every permit pulled on the property, with descriptions and declared costs. Boston, Cambridge and Worcester today.

  4. 04

    Flood zone

    How much of the lot sits inside FEMA's mapped flood zones, measured from the official map rather than a yes or no.

  5. 05

    Thirty years from above

    Aerial photos of the lot from the 1990s to today, with the lot lines drawn over every frame.

  6. 06

    Every fact sourced

    Each line cites the public record it came from, so you can check it or hand it to your agent or attorney.
