Costabella Property Prices 2026: Notarial EUR/m2 on the Marbella Beachfront

In Costabella, the registered sale price, what buyers actually paid at the notary, averaged 4,223 EUR/m2 across all property types in June 2026, with apartments at 4,524 EUR/m2 and resale villas at 4,051 EUR/m2 (listyco notarial data, 2026-06, Consejo General del Notariado). New-build villa prices are n/a for the zone this month. Those are real closing prices, not asking prices, and they reflect an established east Marbella beachfront strip where prime seafront apartments and spacious villa plots sit side by side in a narrow coastal band.

What kind of place is Costabella and who buys there?

Costabella is a compact beachfront strip on Marbella’s eastern side, running along the Mediterranean coast between Los Monteros to the west and Las Chapas to the east. Unlike the gated villa enclaves that define parts of east Marbella, Costabella is a more open, established residential area with a mix of low-rise apartment complexes, townhouses and detached villas. The N-340 coastal road forms its southern boundary, and the beach is the dominant amenity: a stretch of dark sand with protected dune vegetation and several beachfront restaurants and chiringuitos that operate year-round.

The zone sits within the broader east Marbella corridor, which has developed from a hotel-led resort area into a permanent residential address over the past two decades. Costabella itself is quieter than the Los Monteros hotel strip to its west and less developed than Elviria further east. It is a genuinely residential zone rather than a resort zone, which is reflected in the buyer profile: primarily UK, Scandinavian and German second-home owners who want direct beach access without the premium of a gated address or a branded development. A cohort of Spanish families also buys here for year-round living, drawn by the beachfront location and the relative calm compared with the busier stretches of the coast.

The lifestyle is low-key. The streets are residential and walkable to the beach, with restaurants and small commercial premises scattered along the coastal road rather than concentrated in a commercial centre. There is no marina and no golf course within the zone itself; both are a short drive away. For a buyer who wants a beachfront property in east Marbella at a lower entry point than the gated villa enclaves, Costabella is one of the zones where the apartment stock makes that feasible. For the wider context of how this strip fits within the east Marbella corridor, see the Los Monteros and East Marbella buyer guide.

What drives prices in Costabella?

Three factors move the EUR/m2 figure up or down here, and understanding them is the key to reading the registered average.

Beachfront position. The price gradient in Costabella runs from the frontline beach in the south, the highest band, to the properties set back from the sand. Frontline apartments with direct sea views carry the highest prices per square metre, and the apartment figure reflects this concentration of prime seafront stock. Properties behind the front line, still within walking distance of the beach but without direct sea views, sit a step below. The beachfront is the dominant price driver here because the zone’s primary amenity is the beach itself.

The apartment and villa mix. The most notable signal in the Costabella data is that apartments outprice villas on the notarial measure: 4,524 EUR/m2 for apartments versus 4,051 EUR/m2 for villas. This is an inversion of the typical Marbella pattern, where villas usually carry the higher per-metre figure. The explanation is structural. Costabella’s beachfront apartments are concentrated in prime seafront complexes where the per-square-metre price is high because the built area is efficient and the beachfront position is immediate. The villa figure, by contrast, captures larger plots where the land value dilutes the per-metre price: a villa on a generous plot may have a lower EUR/m2 than a beachfront apartment, even though the total price is higher. A buyer comparing the two figures should understand that they measure different products.

Built-out supply and the absence of new villas. The n/a for new-build villas this month tells you that the zone is largely built out. Costabella is a mature beachfront strip with limited room for new detached villa construction, and the registered villa transactions are all resales. The older resale villa figure of 4,000 EUR/m2, sitting just below the broader villa figure of 4,051 EUR/m2, confirms that the villa market is dominated by established stock. This structural scarcity of new supply is the argument for price stability over time in a zone where the building envelope is fixed.

How does Costabella compare to its neighbours?

Costabella occupies a specific position within the east Marbella price hierarchy. It registered 4,223 EUR/m2 across all property types, which places it below neighbouring Los Monteros on the same notarial measure (listyco notarial data, 2026-06, Consejo General del Notariado). The difference reflects the gated beachfront villa premium that Los Monteros commands, combined with its hotel heritage and the scarcity of its frontline plots. Costabella offers direct beach access without that gated premium, which is why it appeals to buyers who prioritise the beachfront over the address.

To the east, Elviria carries a broader range of mid-luxury urbanizations and a more developed amenity base, including golf courses and a commercial centre, which gives it a different buyer draw. Costabella is the choice for a buyer who wants the beachfront position and the quieter residential character, without the amenity range of Elviria or the gated premium of Los Monteros.

Why are registered prices lower than asking prices and valuation estimates?

Registered notarial prices are lower than both asking prices and valuation estimates because they record every signed transaction across the full mix of resales and transfers, rather than the prime, newly listed stock that sets the headlines. A model estimate from listyco market-stats puts current Costabella valuations around 8,035 EUR/m2 (model estimate, not a sale price). Asking prices on portals run higher still (asking, not closing). The 4,223 EUR/m2 registered average is the figure that reflects completed sales.

The two numbers measure different things. The notarial figure is a closing price; the model estimate is a current-value estimate across the standing stock. The gap between them is wider than in some zones because Costabella’s beachfront position means the standing stock carries a premium that the transaction mix, which includes older resales, does not fully capture. A buyer who anchors to the registered average and adjusts up for a frontline apartment or a turnkey renovation is working from what the market did, not what it hopes to do.

For context on what Marbella as a whole is doing, Tinsa’s Q1 2026 data puts the average finished-housing price in Marbella municipality at 3,641 EUR/m2, up 20.53% year-on-year, against a national year-on-year rate of 14.5% and an Andalusia rate of 10.3% (Tinsa, IMIE Mercados Locales, Q1 2026). That Marbella-wide figure covers the entire municipality, including lower-priced inland areas, which is why the Costabella zone-specific registered average of 4,223 EUR/m2 sits above it. The INE Housing Price Index for Q1 2026 reported an annual rate of 12.9% nationally, with second-hand homes up 13.5% and new homes up 9.1% (INE, IPV, Q1 2026), figures directly relevant to Costabella where the stock is almost entirely resale and the new-build villa figure is suppressed.

How should a buyer read Costabella’s numbers?

Use the registered notarial figure as your floor of reality: it is what comparable homes actually closed at. Treat asking prices as the seller’s opening position and the model estimate as a valuation guide for the standing stock. A buyer who anchors a negotiation to the 4,223 EUR/m2 registered average, then adjusts up for a frontline beach position, a turnkey renovation or a larger plot, is working from what the market did rather than what it hopes to do.

The apartment and villa inversion is the most actionable signal in this data. The 4,524 EUR/m2 apartment figure reflects concentrated beachfront stock, while the 4,051 EUR/m2 villa figure captures larger plots where the per-metre price is diluted. A buyer comparing a beachfront apartment to a villa should compare total prices, not just EUR/m2, because the two products deliver different value propositions. For rental potential, the Marbella rental yield guide shows that beachfront east Marbella commands strong seasonal rents, which matters for buyers weighing the property as a part-let investment.
