Property, Land & Risk Maps
Before buying, renting or building, maps can tell you a lot: parcel boundaries and owners, past sale prices, official flood zones, noise, crime, walkability and how much sun a roof gets.

How to choose
Official maps (cadastre, flood zones, zoning) carry legal weight; commercial risk scores and estimates are useful but are models.
Combine several maps: a flood zone map, a historical aerial photo and Street View together tell you more than any one alone.
