Cost depends on a lot of factors and I would not do it if you aren't staying a long time. Not everyone wants a pool and houses with pools are sometimes hard to sell. I had a pool once and thought it was way more trouble than it was worth. After that house we joined a country club and it was a better value in my opinion. Gave us access to a pool and a lot of other amenities without the headaches. Where you live there are probably "yacht clubs" on every corner!
