Definitely less tourists, less buyers katy, for Spain.
It would be financial suicide to buy property in Spain (for Brits) because it would cost 15-20% more in exchange rate alone, plus there is a huge oversupply of horrible mass development over the Costas, too much competition for re-selling, plus costs are too high for purchase and sales.
When the exchange rate swings back in favour of Sterling you could lose a further 15% or more iff you ever needed to get your money back.
Buying anywhere in Europe is not a good idea at present due to the poor exchange rate, so only buy if you need to, or, you are prepared to wait an awful long time to recover the sterling equivalent.
