I don't know what I would do in hot summer days with my kids without our pool! I see them from most rooms and they watch much less tv over the summer, lazy times
The cost of building one, depending on the size can be high. Ours is 40,000 gallons, 8feet so that is an average 100K.
It does increase your house value tremendously and it has long lasting benefits.
As for maintaining it, it does nit cost a lot. We check our water for chemical balance ourselves, we add chlorine, and brush it when needed.
We only have somebody to open and close. He charges a little bit more but he's always available--$360 for opening and the same for closing.
You will need occasional pump or polaris motor replaced or other things but they are not that expensive. Your new equipment and tiles should last for 20 + years with proper use.
I think that is a great investment.
You will also be required to build a tall, view blocking fence and secure gates. Nobody should be coming to your pool, if you have all requirements met, if something happens to a trespasser, hey that is on them. I am not sure what neighborhood the ore posters live but that is crazy.
If you can afford it and have the space, go for it. But don't build something small, some of our fiends have small pools and they are really soaking tubs, it misses e purpose.
Also instal All Safe fence if you have small kids and/or pets.
