Appraisals in the US are typically done for mortgage lenders. I spent a lot of time looking in Cholla Bay, and what I decided was that some list prices were optimistic, although one house we were interested in sold before we could marshal enough liquidity to buy it ourselves. if you are asking because you want to list it for sale, the best you can do is to study the existing inventory on Point2Point and rank your home in that listing. i had a great realtor in Cholla to recommend, but he died earlier this year after a long illness. The only price that actually matters in the end is the one that a buyer and seller agree on.
