I sold a brand new 24' above ground pool with new liner ( in the box), brand new filter, bonding kit and all accessories for $3k. I installed it and filled it n then drained it 2 days later n it sat empty for 3 months and I removed it. Right now, with the prices skyrocketing, and pools hard to find, your chances of selling them for more money is greater. If we were still pre pandemic times, they'd never hold their value. If the pool is not going with a whole set up as I had, you probably won't get as much as I did. People are going to have to track down parts for replacement, liners which are hard to find n take forever to come in and then factor in the age of the pool. Anything older than 3 years old the pool rails and walls become rusted and start to fail. Your profit starts to plummet.
