Is it an Intex Pool? Those are the kind that you buy at Wal-Mart for a few hundred, I wouldn't expect more than a few seasons out of those. If you buy one of the good above ground pools, the ones with a replaceable liner, those can last a very long time, although the liner will need replacement every 5-8 years or so, regardless of warranty claims.
I had a 22 ft round one at our last house, we paid about $2K for it, including an upgraded filtration system, ground prep and professional installation. In my neck of the woods, the ground is mostly stone, so your average in ground pool is a six figure "investment" due to all the stone they need to drill through. My installer insisted he could get our pool to be mostly below grade, with a small backhoe. I told him to have at it, so long as the cost was the same. He got 18" deep before he hit rock, but that was 18" less of an eyesore, so I was happy he did it. He also recommended the more powerful filtration system, b/c the standard ones basically don't do much, and I found his advice to be spot on.
He did not, however, get any chemical business from me, b/c I went to pool school and learned how to manage my water using Bleach, Borax, Baking Soda and Muriatic Acid. Mostly bleach though. One case of Clorox from Costco every week, so the chemical cost was about a dollar a day, and 5 minutes to slowly pour the bleach in front of the filter, so you don't kill the liner.
I also bought one of those floor vacuums, and for the most part, the pool took care of itself! It's really not much work at all, if you spend a few minutes daily...
