I have been going to some open houses because of a similar need - moving an elderly parent into our home. There are a couple of models that I saw that would work nicely, Avalon (currently I don't see any listed on thevillages.com) and the Manatee (one listing
Homefinder - The Villages(R) Homes and Villas for Sale). Using the extra bedroom that's near the bedroom makes for a possible 2nd living/tv/office room.
So yes, there are options around here, although they are becoming more limited all the time, until development begins south of FL-44.
