Having lived in a house with a pool and having friends and family who own them, I would maybe think it worth it if I could easily afford it and had young kids who would benefit from it all the way through high school.
As a person with no kids, I was determined that if the otherwise perfect house came with a pool, I'd drain it and build a deck over it to store wheels or something.
A pool is a hole in your yard into which you pour money, or time and money. And if you ever stop, it turns into a biological disaster.
