Lately, I’ve seen more and more people on forums discussing buying property, from Barcelona to Valencia—the excitement is high. However, the real estate transaction process and regulations here in Spain can be quite different from what we might be used to, with many legal details to watch out for. I’ve just gone through the entire process, ran into a few issues, and learned a lot. Today, I’m organizing my experience to share with you all, hoping to help others have a smoother journey.
Core Document: The NIE Number
First and foremost is your foreigner’s identity number, commonly known as the NIE (Número de Identidad de Extranjero). This number is your passport to all economic activities in Spain. Without it, you can’t even open a bank account, let alone sign a purchase contract or pay taxes. Therefore, the absolute first step in buying a home is to get your NIE
! You can make an appointment at the police station to apply for it yourself, or you can hire a lawyer to handle it for you. For those who prefer convenience, I’d recommend using a lawyer. Although it costs a bit more, it saves you a significant amount of time queuing and dealing with government agencies.

Key Documents: Purchase Contract and Property Report
When you’ve found a property you like and are ready to make a deposit, you’ll typically first sign a deposit agreement (contrato de arras)
. This contract is crucial as it specifies the total price, the deposit amount, and the penalties for breach of contract for both parties. According to Spanish property law, it’s usually stipulated that if the buyer backs out, the deposit is forfeited; if the seller backs out, they must pay back double the deposit. Before signing this contract, I strongly recommend having your lawyer obtain a property information report (Nota Simple) from the Land Registry. This report will clearly show who the owner is, whether there are any outstanding mortgages, liens, or other debts on the property. Don’t skimp on this expense—it’s key to avoiding buying a problematic property!
Main Taxes in the Transaction
Speaking of money, besides the property price itself, the biggest expenses are taxes. The types of taxes differ for new and resale properties, so pay close attention. I’ve put together a simple table here to help you understand:
| Tax Type | Applicable Property Type | Tax Rate |
| IVA (VAT) | New Build | 10% |
| AJD | New Build | Varies by region, approx. 1%-1.5% |
| ITP | Resale | Varies by region, approx. 6%-10% |
Note: According to Spanish real estate law, these tax rates are calculated based on the property’s purchase price, and the specific rates vary between autonomous communities. For example, the ITP rates in Madrid and Catalonia are different. Be sure to confirm the exact amount with your lawyer or real estate agent to budget accordingly in advance.
The final step is to go to the notary’s office to sign the final deed of sale (Escritura de Compraventa), pay the remaining balance, and get the keys. The notary will then submit the documents to the Land Registry to register the transfer of ownership. Once this entire process is complete, the property is legally yours. While the process can be a bit tedious, it’s not that complicated if you take it step by step and have a reliable lawyer assisting you. I wish you all the best in finding your dream home in Spain!
