We purchased our 21 foot pool for $400 from someone on craigslist. It was in brand new condition. We hired someone to dig out and level the hole to bury it up to water level. That cost $150. It was backfilled. Then we had the deck built. The carpenter was brilliant in that he designed the deck so the supports are far enough back from the pool that it causes no pressure on the pool sides. The liner is accessible by removing the 2 deck boards closest to the pool. Landscaper is coming in next month with new sod, irrigation system and palm trees!
