I know as non-residents owning a property in spain we have to pay 18% tax on the profit made on the original purchase price. But if we want to buy another property in spain do we still have to pay this tax and then all other taxes when we purchase a new property? Our aim is to sell our two bedroom apt and buy a smaller 1 bed or even a studio so that we can be mortgage free.

Please advise as to the legalities,thank you
