Scarlett is right. The biggest "issue"s should be 1) how old is your youngest and can you get things safe enough that you can shower or sleep in late and not be freaked out worried that your youngest will end up in the pool without you knowing; and 2) how much effort/expense will it require and is that amount workable for you time/finance wise.
For us, our youngest was almost 5 when we moved into our home with a pool. Brand new home, first time pool-owners. Neither of us grew up with pools, so we had ZERO experience with pool care. Ours is screened in and has an in-pool automatic vacuum (polaris thing). Both cut down on the time and work required to keep it clean. The most time it takes is about 10 minutes once a week during the summer. When it is cooler, I can go 10 minutes every OTHER week. You'll take a water sample to make sure you have the proper balance in your water and treat accordingly, or not. For us, that usually means: a weekly shock treatment during the summer when it gets lots of use, adding a couple of chlorine tabs to the chlorine feeder (part of the pump system), occasionally throwing in a big box of baking soda (the 2 lb size). Clean out the skimmer basket whenever I happen to be around it.
That's about it.
One thing though: If you ever neglect taking proper care, trying to get it back to normal is a NIGHTMARE. One year I was neglectful over the winter and about March I noticed it starting to turn green.... ugh. It took me 3 weeks of tinkering to get it back to normal. What a PAIN. But other than that... I don't give it much thought time or worry. We just love it.
We've been here 5 summers already, and decided about 3 years ago that we had already gotten our money's worth out of it. The kids have so much fun and it is SO much easier to have the convenience of having it right there. Even if you have a "community" pool, you still have to lug everything to the pool. When it is right off your patio, you just open the door, walk outside with your drink and sit down. If one kid misbehaves, they get sent inside and they're done. The rest can keep playing. No wet car when you are done. :))
oh.. and we have a chlorinate pool (not salt) and the chemicals usually run us about $200 a year. That's it. And then a small increase in the electric bill to run the pool pump for about 8 hours a day.
