I just put one on the market (mine - FSBO). Rattlesnake Island facing west (sunsets!), 2 docks (one protected in a cove). Very gentle slope on the peninsula.
Need money for retirement, and we have 3 houses (one in Denver where one of the kids and 2 of the grandkids live) as well as the house in Mass and the Island place. It was either Denver of the island, the grandkids won out

By the way, not to hijack the thread - the final plan is to get a mainland waterfront place (probably not on Winni because the prices are totally out of sight), and sell the house in Mass. Live there in the summer, and Denver in the winter. Not a traditional winter destination, but the winters there are a heck of a lot easier than the winters here !
