When we first moved to Florida, we lived in a house with an in ground pool. We practically lived in the pool that first year. As the years went by (we lived there about ten years) we used it less and less, and by the last year we maybe used it a half dozen times. Maybe. Real life just gets in the way. It’s a big commitment as far as upkeep. I would seriously consider how much you will use it before taking one on.
Ours was not screened, and since it was in full sun, we didn’t need a heater either. The screen would have been one more thing to maintain.
This has been the case for everyone I know that has a pool. I grew up in NC, but we had an inground pool. Our family used it constantly the first 3 summers. After that, we mostly used it, when we had friends over. That was fairly frequent, because we had the only pool in the area. It almost became a burden, because my sister closest to my age & I would have to spend the day in the pool anytime anyone in the neighborhood wanted to come over to swim. (I'm a Southerner, we're not good at saying no.
) After we all moved out, my parents filled the pool with dirt. It became part of the yard. DH, DS & I have lived in 3 communities that had community pools. When we used the pool, we were usually alone. The only time it was ever crowded was when a resident had a pool party. We know several people that spend a lot of money maintaining their pool, just to keep it looking nice. They rarely use it.
OP, I can understand really wanting a pool. We couldn't wait to get our pool, when I was growing up. IME, the odds of not getting tired of it are very low. Knowing what I do, I would never buy a home with a pool, unless I planned to sell it in a couple of years. People aren't trying to be negative. They're just speaking from experience. A community pool is a nice option though.
As far as salt water pools go, my only experience with them is on cruise ships. You couldn't give me a salt water pool. I won't use them. You have the burning eyes, without the advantage of being in the ocean. Admittedly, people with more experience could offer better advice on that.
