Until you get some replies from ABers who live in retirement properties, I suggest that you visit a few. Or have you done that already? My wife and I also had the same idea a year or so ago, and we looked at several different types of property. We noted the costs (service charge, etc.) and compared them with what we pay out at the moment on our bungalow. We also spoke to one or two residents in the properties that we visited. It was an interesting exercise, and, if you have not yet done it, I can recommend it.
