Here in Florida it is great to have of pool. However, even in Florida a pool will generally not really increase the selling price of a house but it will make it easier to sell because a lot of people who live in Florida want a pool. As for maintenance if it is an older pool you can have a lot of maintenance. I just had my in ground pool built last year and it is just about maintenance free. It uses alt to make chlorine and I have a built in automatic cleaner and an automatic solar heater. I have not spent more then 30 minutes on maintenance over the last year. I do think that it would be different in the mor Northern climates and, if it were me, I would not want a pool where I needed to have the extra headache of closing a pool down and reopening depending upon the season. If you really like the house but hate the pool have that reflected in your offering price.
