It is no question that in-ground pool is more expensive since it involves soil excavation and removal. However, it delivers a more permanent and luxury feeling than the other type.
The above-ground pool is suitable for you if the ground condition slopes steeply. In this case, you could install an above-ground fiberglass pool or steel with vinyl liner. There is also a Do-It-Yourself model which can be easily disassembled without compromising the style and quality of the materials. This type is suitable if you still have a plan to move out, and want to install the pool in your new house as well.
