An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.
