You need to let people know where the house is, location does make a difference. What would comparable places be. Some houses have a lot more house than others. Ac, pool, toys available(e.g. kayaks, etc) also make a difference. Who will handle the rental while your sitting watching your money. There is a thread going now on cost to build. Build at the $100 per sq. ft level will rent for much less than one built for $350. You would be probably best served my contacting either real estate agents or rental agents directly rather than a few individuals on this board. There are several agents on this board who I'm sure would be glad to talk with you about the rental market. I have my house on CC not in AC nor do I rent my house out, but I doubt the occupancy rate is very high. Good Luck with your project.
