What Costa del Sol Property Actually Sells For: Asking Prices vs the Notary

The price you read is not a price

An asking price is a request. It carries no evidence that anyone agreed to it. Average them across a town and you are averaging requests, with a bias built in: correctly priced homes sell and leave the sample, while optimistic ones stay listed and keep pulling the average up.

Duplicated listings push the same way. Multi-agency listing is the norm here, so one villa can sit on the market at several prices at once. Across the 1,531 resale properties we list, the same home reaches us through more than one channel often enough that we treat any listing-derived average as seller sentiment, not value.

The notarial record has none of that. It contains only sales that completed. Nothing hoped for, nothing stale, nothing counted twice. Its weaknesses are different: it looks backwards, and it needs enough sales in a zone to mean anything.

An asking price tells you what a seller wants. A notarial price tells you what a buyer agreed to. Only one of those is evidence.

Marbella and Estepona on the same basis

Set the two towns side by side on registered notarial prices for June 2026. Marbella's median is EUR 4,441 per square metre. Estepona's is EUR 3,295. The gap is real. What matters more is the rest of the table, which almost nobody publishes.

Read the bottom row as inventory, not as market data. Those are our own asking-side listings, and they describe what we hold rather than what the market is worth.

Inside one municipality: Benahavis by zone

Benahavis proves the point better than any argument. It is one small municipality, 145.45 square kilometres and roughly 90 per cent mountain, with 9,765 residents. The notarial data breaks it into zones, and inside that single boundary registered villa prices run from EUR 2,740 per square metre in the pueblo to EUR 6,730 at Los Flamingos. Apartments run from EUR 2,191 to EUR 5,026. Nearly threefold, one town, same measure.

Two things there are worth pausing on. El Madronal villas registered above La Zagaleta, EUR 6,652 against EUR 6,483, though La Zagaleta is the name everyone knows. The address premium buyers assume is not always in the numbers. And no Benahavis zone carries a new-build villa figure, because there were too few registered new-build transfers to report one. Where a figure is null we leave it n/a rather than interpolate.

Read the top of that table with care, though, because a per-metre figure misleads on the trophy estates. A house in La Zagaleta or El Madronal is priced by land, privacy and security, not by built area. A very large villa on a very large plot can register a lower figure per square metre than a smaller villa on a tight plot while costing far more in absolute terms. The metric divides by the wrong number. We would not value anything at the top of Benahavis on EUR per square metre alone, and the villas in Benahavis we look at get read as plot and aspect first.

Supply explains much of the rest. Benahavis recorded 800 property transactions in 2024: 83 new-build and 717 resale. The estates are essentially built out and most of the municipality is mountain, so resale is not one route into Benahavis, it is the market. Demand is not local either: across Malaga province, foreign buyers were 34.3 per cent of registered transactions in the first quarter of 2026. Almost everything we list there is resale, including the apartments in Benahavis, a separate market from the estates above them.

Every villa figure in that table sits inside Marbella's own range of roughly EUR 2,289 to EUR 16,889. The strongest Benahavis villa zones register above Marbella's median of EUR 4,441, and the pueblo well below it. Which is the point: whether Benahavis is dearer than Marbella has no answer at municipal level, only at zone level.

A median across 63 zones hides the building

Marbella's EUR 4,441 is a median across 63 covered zones. Inside them, registered prices run from roughly EUR 2,289 to EUR 16,889 per square metre. That is more than sevenfold within one municipality. A number in the middle of a sevenfold range describes nothing. It is an artefact of averaging.

Both ends are Marbella. A buyer weighing an apartment in Marbella several streets back from the sea and a buyer weighing a frontline plot read the same median and draw opposite conclusions. Estepona does the same on a smaller scale: 38 zones, roughly EUR 2,364 to EUR 8,030 per square metre.

This is where Carlos, an architect before he was an agent, tends to interrupt. The zone sets the headline. Within it, the building sets the price: orientation, structure, how the glass was specified, what the community has deferred. Two villas of the same size in the same postcode can be different assets. No median sees that. Our area by area map starts there.

• Marbella's zones differ by more than sevenfold on registered prices.
• Within a zone, the specific building moves the number again.
• A figure with no zone and no property type cannot value your purchase.

Read the figure for your property type

An all-types average blends villas and apartments into one number that describes neither. Atalaya-Isdabe, on the New Golden Mile in Estepona, shows the scale of it. All property types register at EUR 3,301 per square metre. Villas alone register at EUR 4,400. Apartments alone at EUR 2,760.

That is a villa premium of 59 per cent in one zone. Use the all-types figure to value a villa there and you are roughly a third low. Use it for an apartment and you are meaningfully high. Same zone, same month, same source, misleading in both directions at once. It is why we treat villas in Estepona and apartments in Estepona as separate conversations.

The same gap shows in Atalaya-Isdabe: no reliable new-build villa figure exists there either, because the villa stock is entirely resale. The data does not exist rather than being unfavourable. Anyone quoting you one built it from something other than the notarial record.

The logic travels. A villa in Marbella and a townhouse in Marbella do not share a price per square metre in any useful sense. For what a budget actually reaches, what three million buys in Marbella is more honest than any average.

Why the published numbers disagree with each other

Three respected bodies publish figures for this market and they do not match. That is not a scandal. They measure different things, and the confusion comes from treating them as rivals.

• The Consejo General del Notariado publishes registered closing prices: what was signed and paid.
• Tinsa publishes a valuation model. It estimates what property is worth, which is a judgement, not a sale.
• INE publishes a price index. It measures the rate of change, not the level.

Marbella shows it. Tinsa's valuation figure for the first quarter of 2026 was EUR 3,641 per square metre. The notarial median for June 2026 was EUR 4,441. The valuation model sits below the registered sales, and both sit well below portal asking prices. Three numbers, none wrong, none interchangeable.

We lead with the notarial figure for one reason: it is the only one that records something that happened. A valuation is an informed estimate, useful for lending. An index is useful for direction. Neither tells you what anyone paid.

What the market is actually doing

Direction is where the index and the valuation model earn their place. Tinsa's IMIE Mercados Locales rose 15.2 per cent year on year in the second quarter of 2026, the strongest annual rate since the third quarter of 2006. That comparison is worth sitting with rather than celebrating.

The local picture is sharper. Tinsa's Marbella figure rose 20.53 per cent year on year in the first quarter of 2026, against 10.3 per cent for Andalusia and 14.5 per cent for Spain. INE's Housing Price Index rose 12.9 per cent nationally, with new dwellings up 9.1 per cent and second-hand up 13.5 per cent. That reverses the intuition most buyers arrive with: existing stock, not the new developments, leads the index.

Underneath the prices sits a population story. Estepona's padron recorded 79,621 residents in 2025, an all-time high. People are not only buying here, they are registering here, and permanent residents behave differently from holiday buyers. It shows in what sells across Estepona.

How to read a price before you offer

None of this is academic. It changes what you do in the week before an offer, and it takes an afternoon.

1. 1Find the zone, not the town. Ask which of Marbella's 63 covered zones, or Estepona's 38, your property sits in.
2. 2Ask for the notarial figure for that zone and your property type, separately. If only an all-types number exists, treat it as a weak signal, remembering the 59 per cent villa premium in Atalaya-Isdabe.
3. 3Check how much stock the zone has. A figure built on very few registered sales is fragile, and thin zones are common once you narrow by type.
4. 4Compare the asking price to the notarial evidence and ask the seller's side to justify the gap. Sometimes the answer is good: a better building, a rare orientation, a plot that cannot be repeated. Often there is no answer.
5. 5Read the building, not just the number. Structure, orientation, glazing, what the community has deferred. This is where the price is actually made.
6. 6Model the total cost. Transfer tax on an Andalusian resale is charged at 7 per cent, and a new-build carries 10 per cent IVA plus a general AJD rate of 1.2 per cent. Notary, registry and legal fees sit on top of that, which is why we tell buyers to budget in the region of 12 to 15 per cent above the agreed price rather than the tax alone. The full cost of buying is larger than most buyers plan for.

Two of those carry a tax consequence. The declared notarial price is the base on which transfer tax is assessed, subject to the reference value floor. It is the number the tax authority reads. Buyers from outside Spain should walk the non-resident tax map before the offer, and the offer to keys timeline sets out the sequence.

Where this leaves a buyer

There is no average price on the Costa del Sol, and the confident single figure is the tell. The further you get from a municipal median, the closer you get to your purchase. Marbella at EUR 4,441 and Estepona at EUR 3,295 are true about registered sales in June 2026 and close to useless as valuations of anything specific.

That cuts both ways. The reasoning that stops a buyer overpaying in a soft zone also explains why an exceptional building in a strong zone can sit above its zone's median and still be sensibly bought. Working out which you are standing in is the job. It is why we spend more time on Benahavis and frontline beach property than on charts, and why Nueva Andalucia or the Golden Mile is not settled by any figure.

Selling runs the same evidence in reverse: the notarial record is the strongest argument for a price, and the one a serious buyer cannot wave away. That is the sell side conversation. Homes that never reach a portal never enter an asking-price average. Those sit off market. The rest is in our listings.

The words behind the numbers

Notarial price

The sale price registered before a notary when a purchase completes. What was actually paid, published by area by the Consejo General del Notariado.

Asking price

What a seller requests. It is not evidence of value. Averages of asking prices are inflated by stale and duplicated listings that stay in the sample because they have not sold.

Valor de referencia

The reference value set by the Catastro. It is a minimum taxable base for transfer tax whatever you actually pay. A tax instrument, not a valuation of your home.

ITP

Impuesto sobre Transmisiones Patrimoniales, the transfer tax on a resale purchase, charged at 7 per cent in Andalusia. It sits on top of the price you agree.

EUR per m2

Price divided by built area. Useful within one zone and one property type. Misleading across zones, across types, and on large estates priced by land rather than built area.

Median vs average

The median is the middle value, the average the arithmetic mean. The median resists distortion by a few very large sales. Neither survives being taken across 63 zones that differ by sevenfold.

Tinsa valuation

A figure from a valuation model, produced by a regulated valuation company for lending and market tracking. It estimates what property is worth, and is not a record of a sale.

Padron

The municipal register of residents. It counts people who have formally registered in a town, so it tracks permanent settlement rather than tourism or second homes.

New-build vs resale

New-build is a first transmission from a developer and carries VAT plus stamp duty. Resale is any later sale and carries transfer tax instead. In thin zones one may have no reliable data.
