Buying Off-Plan in Marbella: The Real Risks, and How They Are Actually Managed

The risks have names

What makes off-plan feel risky is not danger. It is unfamiliarity. A buyer who would happily inspect a finished villa has no idea what to inspect when the villa is still a drawing.

But off-plan risk in Spain is not a fog. It is a short list of named things, most addressed by legislation written for exactly this situation. Name them and you can check them. The mechanics are in our off-plan buying guide, and the choice between routes is argued in off-plan or resale in Marbella. This piece is only the risk list.

One caveat first, and it is not a formality. This is general information, not legal advice. None of it replaces an independent lawyer, an abogado instructed and paid by you, reading your contract.

Your money is protected by law, from a specific moment

This is the most useful thing on this page, so it gets said carefully. A developer who takes money on account before delivering the home must guarantee its return if the build does not start, or does not complete in the agreed time. The guarantee takes one of two forms: a contrato de seguro de caucion, bond insurance, or an aval solidario, a joint guarantee from a bank. It is an obligation, not a courtesy.

The regime is the Disposicion Adicional Primera of Ley 38/1999, de Ordenacion de la Edificacion, as amended by Ley 20/2015. You will still see the older Ley 57/1968 quoted here, sometimes by people selling you something. It was repealed with effect from 1 January 2016, and the courts now apply it only to older transitional cases.

Now the nuance that matters more than the rest combined. Under the current regime, the obligation to guarantee advance payments is required from the obtaining of the building licence, the licencia de edificacion. Not from the reservation. From the licence.

The question is not whether there is a guarantee. It is whether the licence has been granted, and whether your particular payment sits inside it.

Money handed over before the licence is granted needs its own scrutiny. It is not automatically inside the protection the rest of the schedule enjoys, and buyers are rarely told so. Ask in writing, get the answer in writing, and the category closes. Buyer money should also sit in a special account, separate from the developer's other funds, and named in your contract.

The risks, and how each one is managed

Here is the whole thing on one page. Nothing on the left is unusual, and nothing on the right is heroic.

Why you cannot benchmark a new villa on closing prices

The notaries publish registered closing prices, zone by zone and type by type. It is the best evidence of what people actually paid, and we lean on it constantly, as in our post on what Costa del Sol property actually sells for. Go looking for a new-build villa figure in any Benahavis zone, or in Atalaya and Isdabe, and there is nothing. Not a low number. No number.

That is not a scandal. It is scarcity, and scarcity is most of the reason those addresses are worth what they are. Benahavis recorded 800 property transactions in 2024: 83 new-build, 717 resale. One in ten, which is why the good villas in Benahavis move quietly and quickly.

The consequence is hard, though: the comparables method is unavailable on the exact product being sold. You can benchmark a resale in Marbella against a registered median of EUR 4,441 per square metre, spanning 63 zones and running from roughly EUR 2,289 to EUR 16,889. Or in Estepona against EUR 3,295 across 38 zones, from roughly EUR 2,364 to EUR 8,030. In Atalaya and Isdabe: EUR 3,301 across all types, EUR 4,400 for villas, EUR 2,760 for apartments, a villa premium of 59 per cent. For a new villa there, nothing.

So you read the building instead. The drawings, the orientation, the structure, the specification, the developer's delivered work, the contract. That is not a fallback for when the data runs out. On this product it is the method, and it is why an architect runs this agency.

The render is not the spec. The memoria is

A render is an argument, made by people paid to show the building as the best version of itself, in the best light of the best day of the year, furnished by someone who will not live there. It is not dishonest. It is simply not evidence. What you are buying is described in the memoria de calidades, the specification schedule, and in the plans. That is where the answers live, and why the first pass on any scheme we consider is made by an architect, not a salesperson.

• Orientation, in August as well as January. The terrace in the render is always at golden hour. Yours will not be.
• How the plot is used. Where the pool sits, what overlooks what, and what happens next door once it is built out.
• Floor-to-ceiling heights, spans and structure, which set the feel of a room more than furniture does.
• Glazing, insulation, acoustics and how the services are run. This is comfort, and the electricity bill.
• The specification in nouns: brands, models, thicknesses, and the substitution clause that quietly permits equivalents.
• Which finishes you can still influence, and the honest deadline for doing so.

Then get the memoria annexed to the contract. A specification that lives only in a brochure is an aspiration. Annexed to a contract, it is an obligation. The same reading applies to finished buildings, the subject of our piece on spotting a badly built villa.

Completion is not permission to live there

The building being finished and the building being legally occupiable are two different events, and buyers routinely assume they are one. The document that joins them is the licencia de primera ocupacion: the town hall confirming that what was built matches what was authorised, and may lawfully be lived in.

It is not a formality to collect later. It affects utilities, resale and finance. The management is unremarkable: your lawyer confirms the position with the town hall, and your contract ties handover and the final payment to the licence rather than to a photograph of a facade. The sequence is mapped in our offer to keys timeline.

The order of checks, before you pay anything

Order matters more than effort. Almost every off-plan problem we have seen came from doing the right checks in the wrong sequence, after money had moved. Money moving removes your leverage. So the payment comes last.

1. 1Confirm the building licence. Granted or not, dated, in writing. This question orders everything after it.
2. 2Get the guarantee named. Seguro de caucion or aval solidario, which insurer or bank, which sums, from which date, and confirmation your payment sits inside it.
3. 3Confirm the special account, named in the contract, and check it is where your transfer will actually land.
4. 4Check the land and the title. The nota simple from the registry, who owns the plot, and what charges sit on it.
5. 5Read the memoria de calidades and the plans with someone who reads them for a living, then annex the specification.
6. 6Go and stand in what the developer has already delivered. Not their renders. Their finished buildings, some years on.
7. 7Have an independent lawyer read the contract. Delivery date, delay, permitted changes, warranties, occupation licence, snagging.
8. 8Tie the final payment to the licencia de primera ocupacion and a completed snagging inspection. Then pay.

The costs that are not risks, but surprise people anyway

Some of what buyers file under risk is not risk. It is cost that arrived late. A new-build first transfer carries 10 per cent IVA, a state tax, plus AJD at the general Andalusian rate of 1.2 per cent. A resale pays ITP at 7 per cent instead. That belongs in your budget at the first conversation, not the last. The full picture is in our post on the cost of buying property in Spain, and the position for overseas buyers is in the non-resident tax map.

Two figures, reported straight. Spain's Housing Price Index rose 12.9 per cent year on year in the first quarter of 2026: new dwellings up 9.1 per cent, second-hand up 13.5 per cent. New-build is currently rising more slowly than second-hand nationally. Tinsa's IMIE Mercados Locales, a valuation model rather than a record of sale prices, rose 15.2 per cent in the second quarter of 2026, the strongest annual rate since the third quarter of 2006. New is not automatically the faster horse. It has to be the right building in the right place, which is why we keep an honest map of the coast.

The words, briefly

Off-plan

Buying before the building is finished. You are buying drawings, a specification and a date.

Aval solidario

A joint guarantee, usually from a bank, securing the return of money paid before completion.

Seguro de caucion

Bond insurance doing the same job through an insurer rather than a bank. The other permitted form.

Licencia de edificacion

The building licence. The obligation to guarantee advance payments runs from the moment it is obtained, which makes it the hinge of the regime.

Licencia de primera ocupacion

The first occupation licence. The town hall confirming the finished building matches what was authorised, and may lawfully be lived in.

Memoria de calidades

The specification schedule. What the home is made of, as opposed to what the render implies.

Nota simple

The registry extract. Who owns the land, and what charges sit on it. Cheap, quick, routinely skipped.

Cuenta especial

The special account in which buyer money should sit, held separately from the developer's other funds.

Snagging

The defects found at handover, and getting them repaired. A developer's character shows here.

Who reads this for you

Everything above is doable. That is the point. But notice who it needs: someone who reads a memoria and a set of plans the way other people read a price, and who asks about the licence before anyone asks about the deposit. On a product with no comparables, that reading is not an added service. It is the only instrument there is.

That is what this agency is. Carlos is an architect first and an advisor second, and the order is deliberate. We read the drawings before the marketing. We stand in what a developer has delivered before we put their next scheme in front of anyone. We establish the licence and the guarantee before a client is asked for a euro. That is why the honesty in this post is not a disclaimer. It is the sell.

So look at the new developments we list, a filtered list rather than a feed, or the villas in Marbella for the standard we measure against. Much of the best product never reaches a portal, which is why we hold off-market properties sourced through agency relationships. Selling rather than buying? The same reading applies from the other side, which we cover on selling with us.

And if you are already looking at a scheme, bring it. Talk to us and send the brochure, the plans and the contract. We will tell you the licence position, whether your payments are inside the guarantee, and what the memoria actually says. Including, when it is the honest answer, that you should walk away.
