With about 5000 houses on campsol and about 3000 of these have a pool already installed . As a Camposol non resident I would suggest that you spend 10,000 more and get one wth a pool already installed ( Let someone else take the hit ) as the euro is low and the prices are still good with bargains to be had now.
Think about buying now and renting out for a year through an agent . Look at "Rightmove Camposol" website and you will see bargains about . make sure you consider Sector A and B as first options if you want to be near facilities.
Just also consider pool maintainance is costly but on the good side Camposol had no community fees.
