James,
as for the second question, no we've had no issues with using the home as a business location. In fact, most people prefer it. We happen to live in a very nice neighborhood and I think it's far more relaxing to people to come here rather than a strip mall in a questionable part of town or our downtown location where we had the ad agency.
Guilford is one of my favorite towns. I built there in 1978 and lived there until I changed jobs to a Greenwich ad agency in 1983. I was originally born in Norwich, CT and we had a cottage at Mattunick Beach in RI. Where in RI do you go?
