This was the hang-up previously and why we didn't even consider it, but she is 20 now so no worries from us.
I admit that when we first started looking at homes years ago I was surprised at how little value pools added to a home. Maybe they sold first, but that was about it. It's definitely cheaper to buy a home with one already in it, but I would consider putting one in myself to get the type of system, type of pool, etc. I want, whatever that might be. I would even consider digging the hole to manage the cost.
