I can only advice you to rent first...as you want it to be the place where you are going to stay for the rest of your life.

Spain has a lot to offer (sun,sea,...) but has also some....
Too many British expats have lost all their money on bying land and houses that were illegal...

I ve been living here for 4 years and it took me about 18 months before I signed at the Notary's because the papers weren't in order (it's a relief I studied and checked all the papers in advance (= my profession) otherwise I too would have bought a cat in a bag.

Come and stay for a while and check where you would like to live before buying any property...Prices will be getting down in some time...

Wish you all the best !
