Maine City-Data

I've used the City-Data site before.
Maine Bigger Cities (population over 6000)
Cities/towns between 1000 and 6000
Towns/villages with fewer than 1000
I just found cool feature for house hunters.

Check out "Recent Home Sales" section.
Once on state/city/town page ...
just put address and then request to
have it selected by sale date or distance.
It is slightly outdated but still interesting.
