While you're considering the costs of a new inground pool, you may be wondering if this change will increase the value of your home. Although the national average of ROI (return on investment) for a pool is around 7%, that will vary significantly due to a number of factors. #1. Condition. If you're considering investing in an inground pool strictly to up your resale value and anticipate selling quickly, you can expect the pool to be in good condition - which can help increase your return. #2. Type of pool. Not only will the type of pool impact your ROI but the size can as well. Most buyers still want to see a good chunk of usable yard space in addition to a pool, so keep that in mind when planning. #3. Age. If you don't plan on selling in the relatively near future, you can expect to not receive the same ROI on your pool as if it were new. Things are always changing in the pool industry and buyers will prefer newer, more modern building techniques and materials.
