Tasación hipotecaria in Spain — the bank appraisal that decides how much foreign buyers can actually borrow (2026 guide)

Every foreign buyer with a Spanish mortgage runs into the same surprise. They've agreed a price with the seller, signed the arras, filed a mortgage application with pre-approval numbers that made the sums work, and are three weeks from the notary. Then the bank calls: the tasación came back at €335,000, not the €370,000 they offered, so the loan is €26,000 smaller than the one they had already, in their heads, spent. Completion is in eight days. The seller will not renegotiate. Nobody warned them this could happen.

The tasación hipotecaria is the single most important number in a Spanish mortgage — and the least understood by buyers who arrive from countries where the bank simply lends against the price paid. Understanding it before you sign the arras is worth more than any interest-rate shopping you will ever do.

This is the 2026 guide to the tasación hipotecaria for foreign buyers: what it is, who is allowed to produce one, why it is legally separate from the survey and from the valor de referencia, how the loan-to-value maths actually work, what to do when the appraisal comes in low, how to make the tasación portable across banks under Ley 5/2019, and — the clause that quietly saves foreign buyers €10,000–€40,000 a year — how to write the arras so a low appraisal is the seller's problem, not yours.

What a tasación hipotecaria actually is

A tasación hipotecaria is an official valuation of a Spanish property, produced by an appraiser authorised by the Bank of Spain, for the sole purpose of setting a maximum lending amount against the property as collateral.

It is regulated by two pieces of law that predate the euro and have barely changed since:

• Orden ECO/805/2003, the ministerial order that lays down the methodology — comparable-sales, replacement-cost, discounted-cash-flow, and residual, each mandatory in specified cases.
• Real Decreto 775/1997, the decree that governs the tasadoras homologadas — the appraisal companies registered with, and periodically audited by, the Banco de España.

You can find the current register on the Banco de España's website. There are roughly thirty-five active sociedades de tasación — Tinsa, Sociedad de Tasación (ST), Ibertasa, Tecnitasa, Gesvalt, UVE, Krata, Arco Valoraciones, and a few dozen smaller regional houses.

Two things follow from this that surprise foreign buyers:

1. A tasación is a legal document, not just a number. It is signed by a técnico competente (usually an architect or arquitecto técnico), audit-trailed, and can be inspected by the Banco de España. If the appraiser fabricates comparables to hit a number the client wants, they lose their licence.
2. Only a tasación from a homologated company counts for a mortgage. A friendly estate agent's "valuation", an Idealista tasador estimate, or a private surveyor's figure can inform your negotiation but cannot be presented to a bank as collateral evidence. Banks will simply order their own.

Three completely different numbers, one property

The single biggest source of confusion for foreign buyers is that a Spanish property has three official values, produced by three different processes, that agree with each other roughly never.

Number	Who produces it	What it's for	Typical vs. market
Tasación hipotecaria	Bank-approved sociedad de tasación (ECO 805/2003)	Deciding how much a bank will lend	~95–105% of market
Valor de referencia catastral	Dirección General del Catastro (annual, region-by-region coefficients)	Minimum taxable base for ITP/ISD/AJD	Frequently 85–120% of market — sometimes above the price paid
Valor catastral	Catastro, revised roughly every 8 years	IBI (council tax) base	40–60% of market — usually well below

A fourth number, the valor de mercado, is what the property would actually sell for. That is the one the seller and buyer negotiate; it is the number every appraisal is trying to estimate; it is nowhere written down until the notary records the deed.

A tasación is not a survey either. See our guide to the peritación técnica for the difference: the peritación tells you what condition the property is in; the tasación tells you what a bank will lend against it. They overlap on almost nothing, and a fair number of properties pass the tasación easily while failing the peritación catastrophically. Foreign buyers who assume "the bank checked it" are, in Spain, doubly wrong.

Who orders the tasación, and who pays

Almost always, you — the buyer — order it, and you pay for it. Even though the bank is the beneficiary. Even though the appraiser has to be one of the bank's panel.

The mechanic:

1. You accept the bank's mortgage pre-offer and confirm you want to proceed.
2. The bank tells you which sociedades de tasación they accept and, usually, offers to arrange one directly.
3. You pay the tasación fee — typically €300–€600 for a flat, €500–€900 for a house or rural property, and €900–€1,800 for a large or unusual property (rural finca with several buildings, castillo, restored masía, coastal villa with pool and pool-house).
4. The appraiser contacts the seller or agent, arranges access, visits the property, photographs it, measures it, checks the nota simple and catastro, gathers comparables and issues the report.
5. Total turn-around: 7–15 business days from your payment to the report landing in the bank's inbox. In August, or in a rural comarca with one available appraiser, count on 20+.

The fee is not refundable if the mortgage falls through, the appraisal comes in low, or you change your mind about the property. This is the first place foreign buyers under-budget: you can easily spend €1,200 in appraisal fees across two properties before one purchase completes.

The 60/70/80% loan-to-value rules, and why they're about the tasación, not the price

Spanish banks lend a percentage of the lower of the tasación and the price paid. Which percentage depends on the buyer:

Buyer profile	Typical maximum LTV	Notes
Spanish tax resident, primary residence	80%	Some banks stretch to 90% for salaried applicants under 35 with strong income
Spanish tax resident, second home	70%	Rare exceptions for very strong profiles
Non-resident (any nationality), primary or second home	60–70%	60% is the default at most banks; 70% requires a strong file and often a private-banking relationship
Non-resident buying via SL (company)	50–60%	Some banks won't lend at all to companies incorporated post-purchase

The trap is the words "the lower of". If you agree €370,000, the bank pre-approves at 70% (€259,000), and the tasación comes back at €335,000, the bank will lend 70% of €335,000 = €234,500, not €259,000. You need to find an extra €24,500 in cash, and quickly.

The reverse — a tasación above the price paid — is common (banks like to see "buying below tasación") but doesn't help you: the maximum lending is still capped at the price paid. A €370,000 property tasada at €410,000 still results in a €259,000 loan, not €287,000. If you want to be lent above the price paid — the so-called hipoteca 100% — you need one of the very specific programmes offered by banks against bank-owned stock (Sareb, Cajamar, BBVA/Anida, etc.); see our bank-owned property guide.

Why appraisals come in low, and what to do about it

Spanish tasaciones are more conservative than most foreign buyers expect, for four reasons that compound:

1. Comparables discipline. ECO 805/2003 requires at least six recent comparable sales in the same zona homogénea, and the appraiser must adjust each for date, floor, orientation, condition, and communal amenities. In a market where 30% of transactions still involve undisclosed dinero negro, appraisers only use the notarised prices they can verify. If the neighbourhood has been trading over its notarised numbers, the tasación will lag.
2. Post-2013 caution. After the property crash, the Banco de España tightened audits sharply. An appraiser who consistently prints numbers above the market comparables can be inspected, sanctioned or de-registered. The professional incentive is to under-value, not over-value.
3. Structural or legal red flags. Any of the following will pull the tasación down by 5–25%: an unregistered extension, a catastro-vs-registro mismatch, a coastal setback issue under the Ley de Costas, a rural property with pending DAFO status, a shared boiler or shared meter, an ITE report with pending "desfavorable" findings, or a comunidad de propietarios with an open structural derrama.
4. The "foreign hotspot" premium. In Marbella, Ibiza, Sotogrande and central Palma, agents routinely list at 15–25% above local comparables, banking on foreign-buyer FOMO. Appraisers price against local comparables. The gap lands in your cash contribution.

If your tasación comes back low, you have five options, ranked from best to worst:

1. Renegotiate. Show the seller the tasación (photocopy the summary page). A rational seller understands that every other mortgaged buyer will hit the same number. Roughly a third of low-tasación transactions renegotiate down to somewhere near the tasada figure.
2. Order a second tasación. ECO 805/2003 allows you to commission a second appraisal from a different homologated company. This costs another €500–€1,000, adds two weeks, and is worth it only if you have concrete grounds to believe the first was mistaken (missed comparables, wrong metros, ignored a structural upgrade).
3. Contest the first tasación. Every tasación has a formal recurso procedure. The appraiser must respond within 15 days. In practice this changes the number about 10% of the time and only within a narrow range — worth trying if you can point to a specific error (a comparable in the wrong zone, missed square meters, an outdated cadastral extract), not worth trying to argue "the market is stronger than that".
4. Increase your cash. The default fallback: you fund the shortfall. Watch the source-of-funds file — a last-minute wire from outside Spain lands in front of a compliance officer who is now unenthusiastic about the whole transaction.
5. Walk away. Only if the arras was written to allow it — which brings us to the clause below.

The arras clause that saves foreign buyers from low appraisals

By default, a Spanish arras penitenciales (Article 1454 of the Civil Code) is signed the moment the parties agree — sometimes weeks before the mortgage file is complete, let alone the tasación. If the buyer walks after signing, they lose the deposit; if the seller walks, they pay double.

Which means: if your appraisal comes in €30,000 low and you cannot fund the gap, the default position is that you lose your 10% deposit. On a €370,000 property that is €37,000, gone.

The fix is a single well-drafted cláusula de financiación in the arras, along the lines of:

"El comprador queda expresamente facultado para resolver el presente contrato, sin pérdida ni penalización de las arras entregadas, en caso de que la entidad financiera no le conceda financiación hipotecaria por importe mínimo de €[X] y con un plazo mínimo de [Y] años, y/o en caso de que la tasación oficial emitida por sociedad tasadora homologada resulte inferior al precio de compraventa en más de un [Z]% (por ejemplo, 5%). El comprador dispondrá de un plazo de [N] días desde la comunicación bancaria para acreditar la circunstancia y ejercer la resolución mediante burofax dirigido al vendedor."

Translated: if the bank offers less than €X, or the tasación is more than Z% below the agreed price, the buyer can walk and gets the deposit back. Every foreign buyer's lawyer can draft this in ten minutes; almost none do it by default. You have to ask. See our arras guide for the full anatomy of the deposit contract and the two other clauses foreign buyers should never sign without.

Sellers push back on this clause. That is what negotiation is for. Compromise numbers that generally hold: a 5% tolerance on the tasación, a bank offer of at least 60% of price for non-residents (70% for residents), and 30 days to exercise from the bank's written communication.

Portability under Ley 5/2019 — the €600 saving nobody uses

Since June 2019, the Ley de Contratos de Crédito Inmobiliario (Ley 5/2019) has made tasaciones portable between banks, subject to two conditions:

• The tasación was issued by a Banco de España-homologated sociedad de tasación using the ECO 805/2003 methodology.
• The tasación is less than six months old on the date the new bank accepts it.

In plain English: if Bank A ordered a tasación for your mortgage application and their offer is unattractive (rate, insurance requirement, fees), you can take the same tasación to Bank B and demand they use it. Bank B is legally required to accept it, provided it's within six months and issued by a homologated tasadora on their panel — which, since almost every bank uses the same top eight tasadoras, is nearly always the case.

This saves €300–€900 and 10–15 days per bank you compare. Most buyers, exhausted by six weeks of the process, never invoke it and let the second bank charge them for a duplicate. The banks are not going to remind you. Print the tasación PDF, e-mail it to Bank B's hipotecas team with a one-liner: "Al amparo del artículo 13.2 de la Ley 5/2019, adjunto tasación vigente emitida por [tasadora] el [fecha]. Ruego confirmen aceptación." You will get a reply within 48 hours.

Ley 5/2019 also shifted a chunk of the mortgage's upfront costs — AJD, gestoría, notary, registry — onto the bank. The tasación remains yours to pay. This is deliberate: it's the one document you own.

Common tasación gotchas foreign buyers hit in 2026

• The rural comparables desert. A finca in a village with three sales a decade will have almost no comparables. Appraisers fall back on cost-and-land methodology, and the number can come in 30–40% below what a sophisticated foreign buyer would pay. If you are buying a cortijo, a masía or a vineyard, expect a low LTV and budget accordingly.
• The un-registered square metres. Extensions, converted attics, closed-in terraces and casetas that appear on the ground but not on the escritura do not count towards the tasación surface — even if you can walk on them. Regularising them before the appraisal costs €2,000–€10,000; after the appraisal costs the same and buys you nothing on this purchase.
• The furnished-property mirage. A fully furnished flat in a foreign-heavy zone often lists at a "llaves en mano" premium of 8–15%. Furniture doesn't count for tasación. If your offer includes the contents at list price, expect the LTV to be applied only to a stripped-out valuation.
• The pool that was never legalised. Roughly a fifth of Spanish coastal villa pools were built without permit. Appraisers strike them from the tasación surface and often from the valuation itself.
• The community with an open derrama. Any comunidad de propietarios with a voted-but-not-yet-collected special assessment for structural work (façade, roof, ITE-driven intervention) will be flagged on the tasación and the future obligation deducted. See our comunidad guide.
• Non-EU buyer, military zone authorisation pending. The bank will refuse to disburse until the Ministry of Defence authorisation is on the file. The tasación can still be ordered, but the mortgage will not sign at the notary. Sequence matters.
• The three-month expiry surprise. Banks internally treat tasaciones as "fresh" for six months by law but often for only three months by policy. If your file drags — because of a slow Modelo 210 predecessor filing, a delayed NIE, or a source-of-funds review — you may be asked to pay again.

Timing the tasación relative to the arras

The single decision that separates confident foreign buyers from panicked ones: when in the process do you commission the tasación?

Three timings, ranked:

1. Best — after arras, with a financing clause. You sign the arras with the financing/tasación clause described above, pay the deposit, order the tasación immediately, and either proceed, renegotiate, or walk with your deposit intact.
2. Second-best — before arras, informally. You ask the bank to run their internal automated valuation (a valor automático — free, generated by their credit scoring engine, based on the same comparables an appraiser would use) before you sign. It is not a tasación and cannot bind the loan, but it will surface a €30,000 gap early. Any Spanish bank hipotecas team will do this in 48 hours if you ask.
3. Worst — after arras, no clause. The default position for a foreign buyer who signed at the notary's desk in a rush without a lawyer. If the tasación comes in low, you cover the gap or lose the deposit. This is the transaction the appraisal industry earns its money on.

If you are still looking, not yet signing

The best hedge against a low tasación is not a clever clause; it is a property that isn't priced 12% above the local comparables in the first place. The overwhelming majority of tasación shocks happen because a foreign buyer paid a foreign-buyer premium on a property listed on a foreign-buyer portal to a seller who priced against foreign-buyer expectations.

The properties Buvivo surfaces come from agents and owners responding to a specific brief you posted — region, budget, condition, priorities. The pricing conversation happens with the appraiser's number as an anchor from the start, not a shock at week four. Post what you're looking for on Buvivo and the tasación stops being a landmine and starts being a routine paragraph in the mortgage file.
