Building a swimming pool may or may not increase home value. An appraiser can help you determine whether or not adding a swimming pool will affect the fair market value of your home. For example, if your home is valued at $300,000 without a pool and would be worth $310,000 with a pool, it may not be worth the cost, particularly if installation costs upward of $60,000. It's a good idea to do extensive research and math before you make a final decision about whether or not to get a home equity loan for a pool.
