If you are looking at purely a holiday home and are in a position to buy then there should be nothing stopping you. In fact if you have the funds available then you are the position to strike a very good bargain.
I dont sell property in Spain but I would have no hesitation in recommending it for the purchase of a holiday home (again I'm leaving investment out of the equation) as you would be in a great position for a bargain. In terms of it holding it's value, I think the Spanish market has bottomed out and if you buy in the right location in Spain you should see the capital value of your property stay stable if not increase slightly.
