is it possible to get the pumps running off solar power, or do they require to much 'juice' for this?
Easy option is to buy a house (or rent) that actually has one already.
Outer suburbs (20-30 mins from city) over 15 years old (north and south) often have larger blocks with room for pool and garden whereas newer properties may be on smaller blocks where the pool is the back garden (as someone else mentioned).
We have an unheated saltwater pool (it's over 20 years old) which is generally in use November through March. Cleaning isn't too hideous a job (says she who rarely does it!) although it does take some effort at the start of the season.
