Buying or renting in Spain? Never sign before making these checks

A twenty-minute viewing, a warning that another buyer is waiting and a signature before the visit is even over. It’s a trend that is  occurring more often than most buyers realise. But what that rush can hide though, from damp walls to a debt attached to the property, usually only surfaces once the deposit is already gone.

It is a familiar script for anyone flying in for a few days to find a home in Spain. An estate agent mentions a couple viewing the same flat that afternoon, or explains that the seller already had one buyer pull out and wants a fast decision. A reservation fee or an arras agreement, a preliminary contract that puts a deposit against the sale, gets signed there and then, and sometimes before a lawyer or translator has looked over a single document. 

Renters are facing the same pressure, as more than one in seven rental homes in Spain are taken off the market within 24 hours of being listed, so agents and landlords know a hesitant tenant will simply lose the flat to someone faster.

The property itself rarely goes through any changes between viewing and signature. What can come as a surprise after signing, though, is how much the buyer or renter actually knows about the property’s extra costs. A home’s true cost is not the figure on the listing, but that figure plus whatever repairs, debts or legal problems come attached to it, and being told a decision is needed within hours should usually be a sign to slow down, rather than speed up. 

The Land Registry extract that shows who really owns the property

A nota simple is a short extract from the Land Registry, the Registro de la Propiedad, that names the legal owner, describes the property and lists any mortgages, embargoes or other charges attached to it. It costs roughly €9 to €15 and can be requested online through Spain’s official body of registrars, usually arriving within a day or two.

The point is not just confirming the seller is real. A nota simple from weeks before a viewing can already be out of date, so buyers should ask for one dated close to the signing, not whichever copy the agent has on file. More than one in ten homes sold in Spain in early 2026 went to a foreign buyer, with Britons still the largest single nationality among them, and cash buyers in that group face particular exposure since no bank is involved to insist on the check a mortgage lender would normally make. EWN’s guide to buying a home in Spain covers the wider paperwork trail this sits inside.

Community debts and failed inspections that transfer with the keys

Unpaid community fees do not disappear when a seller moves out. Under Spanish law, a new owner can be made to cover debts the previous one left behind, up to the amount built up in the sale year plus the three years before it. A quick certificate from the community administrator reveals any arrears, plus any special levy, or derrama, already approved for roof, lift or facade repairs.

Buildings older than 50 years, sometimes 45 depending on the region, must also pass a technical inspection, the ITE or IEE, repeated every 10 years. A failed inspection forces repairs within months, and in Andalucía alone, skipping it brings fines of €3,000 to €6,000. Whoever owns the property when that order lands pays for it. 

Damp, cracks and old wiring a short viewing may not reveal 

A single visit rarely gives anyone time to check what really matters, especially in the summer months: whether the walls show damp or hairline cracks, whether the roof and drainage cope with heavy rain, or whether the wiring, plumbing, heating and air conditioning are original to a building built decades ago.

These are the repairs that turn a bargain into a burden within the first year of moving in. An independent survey arranged between viewing and signature costs far less than discovering a rewiring job once the keys are already in hand.

Flood maps and radon zones are tied to the address, not the listing 

Some risks have nothing to do with the building itself. Spain’s national flood-mapping tool, the SNCZI, shows which streets sit inside a recognised flood zone, something that has mattered to buyers more than ever since the 2024 Valencia floods.

Radon gas, a naturally occurring risk in granite areas such as Galicia, Extremadura, Castilla y León and parts of the Madrid sierra, is worth asking about too. Nearly half of Spain’s municipalities fall inside a classified zone, though that alone doesn’t say much about any individual home without a proper test. 

What the reservation fee actually allows a buyer to walk away from

The most common version, arras penitenciales, lets either side pull out, but at a cost. If a buyer backs out, they forfeit the deposit, but if a seller backs out, they must return double. What counts as backing out sits in the wording of the contract signed under pressure, and must be checked diligently so as to not be caught out by any consequential small print conditions. EWN has previously reported on why getting legal advice on a reservation contract matters before any money changes hands.

None of this takes long against the promise that another buyer is waiting. It just takes longer than an afternoon, and a seller unwilling to allow that is rarely one worth trusting with a deposit.
