Denise, I think that the problems you might have observed are unique to the home(s) that you have viewed. Bridgewater, the subdivision, is not necessarily reputed to have "foundation issues". That being said, a certain subdivision could become stigmatized by a larger than average group of houses that have a specific problem. That is generally due to a builder that has an unresolved construction problem, and builds exclusively/nearly exclusively in that subdivision.
Consult your realtor, if you have one, and they should be able to direct you to a structural engineer, or the like, that can give you an indepth overview of what to look for in reference to foundation issues. Regardless, of what you see, make sure you, upon making an offer, hire a quality inspector. If they see some of those "clues", they will refer you to an expert-like a structural engineer. It might turn out that the "clues" are no cause for concern, but if they are symptoms of a deeper problem, it will be money well spent.
If you do not have a realtor that is committed to you and vice versa, feel free to give me a call. Good luck, either way. 260-312-6077.
