There are several reasons why you might consider buying an above ground pool:

1. Cost: Above ground pools tend to be more affordable than in-ground pools, both in terms of initial purchase price and ongoing maintenance costs.
2. Installation: Above ground pools are generally easier and faster to install than in-ground pools, as they do not require extensive excavation or construction work.
3. Flexibility: Above ground pools can be set up in a variety of locations, including on a deck, patio, or lawn. They can also be easily disassembled and moved to a new location if needed.
4. Safety: Above ground pools tend to be safer than in-ground pools, as they are typically surrounded by a fence or barrier that can help prevent accidents.
5. Maintenance: Above ground pools are generally easier to maintain than in-ground pools, as they have fewer components and do not require as much specialized equipment.

Overall, above ground pools can be a great option for those who want to enjoy the benefits of having a pool at a lower cost and with less maintenance.
