One free tool to know your costs. One paid product to check the legal title. One free network to close safely.
Unlike the UK or US, Spanish law places the entire burden of due diligence on the buyer. The notary will not protect you. The estate agent represents the seller. And the documents — the nota simple, the escritura, the Catastro entry — are all in Spanish legal language that most foreign buyers cannot read.
93,000 foreign buyers purchased in Spain in 2024. Most had no idea what the property's legal status was before they signed.
Most buyers go through all four stages. PropDue covers three of them. Here's how it fits together.
You know you want Spain, but you're still deciding where. Costa Blanca? Costa del Sol? Valencia city? Mallorca? This stage is research — reading, watching YouTube property tours, browsing Instagram. You don't have a specific property yet.
Area Match is in development for later in 2026. If you're still deciding where to look, start with our town and area guides.
You're on Idealista. You've found a property you like — or several. You know the asking price. What you don't know is what you'll actually pay to buy it, and what it will cost you every year to own it. This is the question that PropDue answers for free, before you book a flight.
You've visited. You like it. You're seriously considering making an offer. Before you commit your deposit, you need to know what's on the legal title. This is the stage where surprises — active mortgages, embargos, size discrepancies, unregistered extensions — get discovered. Or don't, if you skip this step.
You've done the Legal Review. The title is clean. You're ready to make an offer and get to completion. You need an independent bilingual lawyer to review the arras contract and handle the escritura. You may need a Spanish mortgage. PropDue introduces you to vetted professionals who do this every day for foreign buyers.
PropDue is not a replacement for a lawyer. It is how you decide which properties are worth spending €1,500–4,000 on a lawyer for — and what to ask them when you get there.
Pay for what you need, when you need it.
No subscription. No account needed for the Cost Calculator. One payment per Legal Review.
