What taxes and additional costs are associated with buying property?

When purchasing property on the Costa del Sol, the price is supplemented by taxes, notary fees, Land Registry fees, and legal costs. For resale properties, a 7% transfer tax applies. For new developments, the purchase is subject to 10% VAT plus 1.2% stamp duty.
As a general estimate, you should calculate approximately 10% of the purchase price for taxes and associated costs on resale properties, and around 13% for new developments.
