Reading a Spanish listing and judging the asking price

Terms used

• Superficie construida — Superficie construida is the built area, measured to the outer faces of the walls and including terraces and a share of common areas.
• Superficie útil — Superficie útil is the usable floor area inside the walls, excluding walls, columns and common areas.
• Nota simple — A nota simple is a short extract from the Property Registry showing the registered area, owner and charges.
• Catastro — The Catastro is Spain's land and property register, which records each property's area and boundaries for tax purposes.
• Tasación — A tasación is a valuation of a property by a certified appraiser.
• Entresuelo — Entresuelo is a mezzanine floor between the ground floor and the first floor.

Key rules

• Same basis: Only compare price per m² when both figures use the same area, built or useful, and treat terraces the same way.
• Asking prices: Portal asking prices are not official and are usually above what flats finally sell for.
• Registered area: Check the listing's area against the nota simple and the Catastro certificate before you sign.
• Big differences: If the areas differ a lot, take it to a notary or lawyer before you commit.

Start with the area: built or useful?

Check which area the listing shows before you look at any price. A price per m² only means something when you compare like with like.

• Superficie construida (built area) is measured to the outer faces of the walls. It includes interior walls, terraces (usually counted at 50%) and a share of common areas such as stairwells and lobbies.
• Superficie útil (usable area) is the floor you can actually walk on, inside the walls. It leaves out walls, columns and common areas.

Useful area is typically about 80–90% of built area. Listings often do not say which one they show. Subsidised housing (VPO) is measured by useful area, while the Catastro and many listings use built area. If the listing is unclear, ask the agent in writing.

Floors

• Bajo (planta baja) is the ground floor.
• Entresuelo is a mezzanine floor between the ground and first floors, common in Catalonia and Madrid.
• Principal is the first main floor above it.
• 1º, 2º and so on are the floors above. Izquierda or derecha is the door side.
• Ático is a top-floor flat, usually set back and with a terrace. Sobreático and dúplex are variants.
• Semisótano is a half-basement.

Light and position

• Exterior means the windows face the street or outside.
• Interior means they face an inner courtyard or light well. Expect less light and more noise from neighbours.
• Orientación sur, norte, este or oeste is the direction the main windows face.
• Con ascensor means there is a lift.

Check the listed area against the registers

The advertised area often differs from the official records. An ad may count built area with terraces, while the Registro de la Propiedad may hold a useful or built figure from an old deed.

1. Request a nota simple from the Registro de la Propiedad.
2. Get the free descriptive and graphic Catastro certificate from the Sede Electrónica del Catastro. Navarra and the Basque Country have their own cadastre bodies.
3. Compare area, owner, charges and boundaries.

A gap can point to an unregistered extension or illegal works. That can cause trouble with the deed, the mortgage valuation or taxes, and may need regularising. In some cases Spanish law allows a price claim for an area shortfall. Raise any large difference with a notary or lawyer before you sign. An architect can measure the flat for you.

Judge the price per m²

Divide the asking price by the area, then compare it with the right benchmark.

1. Match the basis. Use built or useful on both sides, and note whether terraces are included.
2. Use official figures for the same municipality or district. Asking prices on portals are not official and are usually above final sale prices.
3. Adjust for the flat. Age, floor, lift, condition, orientation, views, parking and storage are often priced into the m² figure.
4. Compare several similar listings in the same street or neighbourhood.
5. Treat averages with caution. Small samples, luxury or very old stock and delays in the statistics distort them.

Where official price figures come from

Each source measures something different, so do not mix them.

• The housing ministry (Ministerio de Vivienda y Agenda Urbana) publishes quarterly appraisal-based average €/m² for municipalities above 25,000 inhabitants, provinces and regions.
• The property registrars publish quarterly and annual figures on registered sales, including €/m² by region and province.
• The notaries' council publishes monthly and quarterly data on notarised sales, with €/m² by region and province.
• The national statistics office (INE) publishes a housing price index by region. It is an index, not €/m².
• Valuation firms also publish appraisal-based figures.

For a firmer basis on one specific flat, order a tasación from a certified appraiser. The documents and FAQ below cover the paperwork and common questions.

Documents you need

• Nota simple from the Registro de la Propiedad (Property Registry): shows the registered area, owner, charges and boundaries, so you can compare them with the listing.

• Catastro certificate, descriptive and graphic: the Sede Electrónica del Catastro issues it free, and it shows the cadastral area to compare with the advertised one.

• Tasación (valuation) from a certified appraiser: a firmer basis for judging the price, if you want one.

Frequently asked questions

Is the useful area always smaller than the built area?

Yes, useful area is smaller than built area, usually by about 10–20%, because it leaves out walls, columns and shared areas. Built area also counts terraces, usually at 50%.

Can the area in the listing differ from the registered area?

Yes, the advertised area often differs from the area in the Property Registry and the Cadastre, for example when the ad counts terraces or the registry holds an old deed figure. Ask for a nota simple from the Registro de la Propiedad and a free Catastro certificate, then compare. Bigger gaps can point to unregistered extensions, so raise them with a notary or lawyer before signing.

Should I compare the asking price with sold prices or other listings?

Yes, compare it with both, but give more weight to official sold or appraised prices for the same municipality or district. Asking prices are usually above final sale prices. Then check several similar listings on the same street, and ask a certified appraiser for a tasación (valuation) if you want a firmer basis.

Which official sources give price per m² figures?

The Ministerio de Vivienda publishes average appraised prices per m² each quarter for municipalities above 25,000 inhabitants. The Registradores and the notaries publish €/m² by region and province from real sales. The INE price index is an index, not a €/m² figure.
