Plug in your current address or, better yet, the address of a property you are looking to buy and Walk Score:
Helps homebuyers, renters, and real estate agents find houses and apartments in great neighborhoods. Walk Score shows you a map of what's nearby and calculates a Walk Score for any property. Buying a house in a walkable neighborhood is good for your health and good for the environment.
Walk Score gave my home a score of 83/100 which makes sense as we live in a very walkable small city. My only criticism, I wouldn't count 7-11 as a grocery store.
