When purchasing a property in Spain there will be costs that need to be considered. Both on new and resale properties the tax rate stands at 10%. On top of this there will be notary charges, land registration and we advise you have a lawyer. I cannot give you an exact amount but 13% should be enough to cover everything with no surprises (cost of lawyers vary). If you intend to get a mortgage in Spain, this will inflate the cost, as there will be a startup cost and extra notary charges.
