You could be sitting on a pile of gold! In a market on the upswing, it is worth slightly more than the last comparable home sold in your community. Parks or mobile home communities all have their own unique value. As an example, when a lender sends out an appraiser to provide them with the value of a mobile home, the appraiser is not allowed to go outside of the community for comps unless there are no comparable homes that have been sold within the community.
