Village Center

Hey, googlers, here is a challange:

My wife and I are attacted to the idea living within three blocks (walkable, no hillsides or limited access roads) of a village center.

I can describe them, but I am not sure how to search for them. In particular, I need to search for houses for sale within village center areas.

A village center will be a commercial "main street" (not a mall, malls are anathama to village centers) that is compact, say 5 blocks by 2 blocks. It will contain as many as possible of: library, post office, pharamacy, grocery store, coffee shop (not Starbucks -- we are too old for that harsh roast), hardware store (not Lowes or HomeDepot), and restaurants.

The perfect house will be built before 1940 and be within three blocks of one of these village centers.

The search is daunting, mostly because it is not (yet) automated.

What I would like to have is a mapping function that will plot village center areas, the balloon can list the stores in the area, and houses for sale that meet the nearness criterion. The balloon for the house can even include the agent's name and phone number -- what realtor could complain about that?

Then my search for the perfect home could be just a matter of panning around on the map.

Now if the parameters of village center and the distance from one were all customizable, then this would be a universal house finder tool.

Let me know if you have any questions. I'll let you alone now and stop bothering you so you can get to work.

Thanks!
