Give yourself time not only view properties but to explore the area as well. We, on average, spend two days showing clients properties and then if they buy, a few more hours with them setting up bank accounts etc. Even after that time you have still not had chance to explore the area.
I strongly suggest spending a week here, stay in a cave home, just for the experience and have a holiday so that even if you are unable to find the property you want this time around you will have gotten to know the area well and had a holiday in a truly beautiful area of Spain.
IMPORTANT, buy a good map of the area before you leave the UK. The hire car companies do not provide decent maps and you cannot buy them in arrivals at the airport. You probably can purchase them at service stations but most people, once they get going don't want to stop. The roads in southern Spain are superb, the signposting isn't quite so good, so a map can save you hours on your journey here and is essential if you go sightseeing in the area.

A good Spanish route planner.

Europe-wide. Works well, if a bit slow.
