a couple of suggestions:
is it a listed property or a for sale by owner? if it is listed, the realtor should provide a 7 page disclosure form filled out by the seller. you also might do the following prior to going under contract if the property is not listed:
-- go to the town listers and look up the recent property transfer amounts (public knowledge due to transfer tax). probe the lister for more information
-- find out when they bought it, and look up the warranty deed, maybe go a couple owners back. if there was a rebuild, you will find zoning and building permits in the card catalogs along with the deeds. while you're in the land records try to find a survey if the current owners did not provide one.
-- talk to town zoning, get an aerial printout and see if there is any known development that will adversely affect your new prospective dwelling
-- talk to the neighbors, they would like to meet you anyways.
-- get a good inspector. call me if you want some names.
