I just went through the whole process of buying and selling a pre-owned apartment in Barcelona, and I’m completely drained… I’ve seen many people on forums asking about the property transaction process in Spain, so I decided to organize my experience and the pitfalls I encountered to share with everyone. I hope this helps those who are considering buying or selling property, so you can avoid making the same mistakes!

The Core Process for Buying and Selling Property
Whether you are the buyer or the seller, the overall framework of the process is quite similar. It mainly consists of: Preparation Stage -> Signing the Reservation Agreement -> Signing the Public Deed of Sale -> Registration and Tax Payment. However, the documents and key points for each party are very different.
As the Buyer
As the buyer, the most important things are your funds and your identity. First, you must have an NIE number (Número de Identificación de Extranjero), which is your identification number for all major economic activities in Spain; it’s impossible to get anything done without it. Next, you’ll need to open a Spanish bank account to pay for the property and related taxes. You can search for properties on websites like Idealista and Fotocasa, or you can work with a real estate agent. After finding a property you like, you must ask the seller for the latest Nota Simple (property information report). This document is like the property’s ‘ID card’ and contains crucial information such as the owner’s details, any existing debts, and the property’s size. It’s also essential for verifying there are no hidden issues, such as illegal squatters, known as Okupa. Once you’ve confirmed everything is in order, you can sign the reservation agreement (contrato de arras), which usually requires a deposit of around 10% of the total price. After signing this agreement, if the seller backs out, they must return double the deposit. If you back out, you lose your deposit. The final step is to go to the notary’s office to sign the public deed of sale (escritura pública), pay the remaining balance, and the property is officially yours!
As the Seller
As the seller, you’ll need to prepare even more documents. In addition to the Nota Simple mentioned above, you must provide the property deed (escritura), proof of payment for the latest property tax (IBI), a certificate showing community fees are paid up, the Energy Performance Certificate (CEE), and so on. If you have an outstanding mortgage on the property, it must be settled either before or at the time of the sale. After the buyer pays the deposit, you must have all documents ready before the date of signing at the notary, as stipulated in the agreement. After signing the deed at the notary and receiving the payment, you’re not done yet. You still need to declare and pay Capital Gains Tax within the specified period. This tax is crucial; make sure you understand how to calculate it, or you could face trouble with the tax authorities.
Both buying and selling involve various taxes and fees. I’ve put together a simple table to give you a clear overview. Specific tax rates may vary by region and year, so this is for reference only. For the actual transaction, it’s best to consult your lawyer or tax advisor.
| Fee Type | Paid By | Estimated Cost |
| Property Transfer Tax (ITP) | Buyer | 6% - 10% of the property price |
| Notary Fees | Mostly paid by the buyer | Several hundred to over a thousand euros, based on the property price |
| Property Registry Fees | Buyer | Several hundred euros |
| Municipal Capital Gains Tax (Plusvalía) | Seller | Calculated based on years of ownership and land value |
| Capital Gains Tax | Seller | Starting from 19% of the profit |
| Agency Fees | Usually paid by the seller | 3% - 5% of the property price + VAT (IVA) |
Buying or selling property in Spain is a very formal legal process. It is highly recommended to hire a reliable lawyer to assist you throughout, especially if you are not familiar with the language and local laws. Although it’s an extra expense, a lawyer can help you avoid many risks and is absolutely well worth the money!
