Refurbish or Buy Off-Plan? An Honest Comparison for Marbella Buyers in 2026

The way this question usually gets framed is as a matter of taste: character and charm on one side, modern convenience on the other. That framing is not wrong, but it is not the part that decides most purchases. What actually decides it is money, time and risk tolerance, and those can be compared properly rather than gestured at.

This article does that comparison with current figures. It covers what each route actually costs, how long each realistically takes, where the risks sit, the tax treatment that differs meaningfully between them, and the planning situation in Marbella right now that affects one route considerably more than the other. If you finish it knowing which side you fall on, it has done its job.

Here is the shape of the two routes side by side. Figures are current as of 2026 and should be treated as planning benchmarks rather than quotes.

The single most useful line in that table is the tax row, and it is the one most commonly left out of these comparisons entirely. On a €2 million purchase, the difference between 7% and roughly 11.2% is about €84,000, before any works are considered. That does not settle the question on its own, but it belongs in the calculation from the start rather than as a surprise at the notary.

Refurbishment is the route that gives you access to Marbella's established addresses. Sierra Blanca, Nueva Andalucía, the Golden Mile and Hacienda Las Chapas are, in practical terms, built out. New supply in these areas comes almost entirely from demolition and rebuild, or from renovating what already stands. If your priority is a large plot with mature planting five minutes from Puerto Banús or the Golden Mile, refurbishment is often not one option among several. It is the only route available.

The cost. A full renovation to a high contemporary standard currently runs €1,500 to €2,500 per square metre, depending on specification and the condition of what you start with. On a 400 m² villa, that is €600,000 to €1 million on top of the purchase price. Structural work, replacing services, or reconfiguring layouts pushes toward and beyond the upper end.

The timeline. Six to nine months of actual construction is a reasonable expectation for a comprehensive renovation. What extends it is everything before and after: design, the licence application, technical reports, and final inspections. Twelve to eighteen months from purchase to moving in is realistic in Marbella, and worth planning for rather than hoping to beat.

The variable that catches people out. Costs on the Costa del Sol have risen roughly 38% cumulatively since 2020, driven by labour shortages and material inflation. A figure a friend quoted three years ago, or a number you saw in an article written before 2024, will materially understate today's cost. Re-quote at the point of committing, not at the point of first enquiry. Our guide to building a luxury villa in Marbella sets out current construction costs in more detail, and much of it applies to major renovation as well.

The upside that is genuinely real. In established complexes and villa areas, the gap between original-condition and fully renovated stock is wide enough that buying well and renovating properly is one of the more reliable value strategies in Marbella. It is not a guaranteed profit, and it requires budgeting the works honestly, but the arbitrage exists in a way it simply does not in a new development where every unit is delivered to the same standard.

Off-plan buying trades personalisation and location choice for cost certainty and a finished product. For buyers who do not want to run a project, that is a substantial trade in their favour.

The cost certainty. A fixed-price contract, once signed, removes the largest single source of budget uncertainty in a renovation: the unknowns that only appear once you open up an existing building. What you agree is what you pay, subject to your contract terms. That is worth a great deal to buyers who value predictability.

The timeline. Developers typically quote eighteen to twenty-four months. The honest planning assumption is closer to three years from reservation to keys, because construction schedules on this coast slip more often than they hold. Anyone whose plans depend on a specific move-in date should build in real buffer.

The protections you are legally entitled to. This is the part buyers most often fail to check, and it matters more than almost anything else on this route. Under Spanish law, every payment you make before completion must be covered by a bank guarantee or insurance policy. Confirm in writing that this protection is in place for each staged payment, before you transfer anything. Your lawyer should verify this as a matter of course, and if a developer is evasive about it, that is a meaningful signal.

The other diligence that matters. Review the developer's track record on previous projects, particularly their delivery timelines. Confirm the current expected completion date directly with the sales team rather than relying on marketing material that may be months old. And pin the specification down in the contract, since renders are not contractual documents. Our complete guide to new-build and off-plan property in Marbella covers the full process.

Where off-plan supply actually is. New development is concentrated in Estepona and the New Golden Mile, La Quinta, Benahavís and parts of San Pedro rather than in the established prime areas. This is the real constraint on the off-plan route: it is not usually available where the oldest and most sought-after addresses are.

Marbella spent roughly a decade operating under a 1986 urban plan, after its 2010 masterplan was annulled by the Supreme Court in 2015. The new PGOM has now received its favourable regional report and is close to final approval, which is genuine progress.

But the document that actually governs what you can build, extend or reconfigure on a specific plot is the POU, and that is still in an early stage, with final approval realistically expected in 2027 to 2028. For a refurbishment buyer, particularly one planning an extension, an additional floor, or a demolition and rebuild, this means the rules that will apply to your project are not yet fully settled. That is not a reason to avoid refurbishment, but it is a strong reason to confirm the current planning position for your specific plot in writing, with an independent lawyer or architect, before committing. Our guide to the PGOM and POU explains where things currently stand.

Off-plan buyers are considerably less exposed to this, because the developer has already secured the licence before selling. The planning risk on that route sits with the developer rather than with you, which is one of the quieter advantages of buying new.

One further practical point on refurbishment timelines: licensing speed varies significantly by municipality. Marbella's own process has historically been among the slower ones on this coast, while Estepona, Benahavís and Mijas Costa have typically processed comparable applications considerably faster. If your project is in Marbella specifically, start the licensing conversation early rather than waiting until the design is finished.

Rather than weighing charm against convenience, work through these questions in order. They tend to resolve the decision faster.

Where do you actually want to live? If the answer is Sierra Blanca, the Golden Mile, Nueva Andalucía or a comparable established address, off-plan is largely unavailable and the question mostly answers itself. If you are open to Estepona, the New Golden Mile or Benahavís, both routes are genuinely on the table.

When do you need to be in? If you have a fixed date driven by schools, a relocation or a sale elsewhere, off-plan carries more delivery risk. If your timeline is flexible, that risk costs you less.

How much project management can you take on? A refurbishment needs an architect, a builder, and someone overseeing them, whether that is you, a project manager, or your agent. If you are not in Spain regularly and do not want to appoint someone, that is a genuine argument for off-plan.

How much cost uncertainty can you absorb? A fixed-price new build gives you a number. A renovation gives you an estimate with a contingency, and on a complex older property the contingency gets used. If a 15% overrun would be a serious problem rather than an annoyance, that points toward off-plan.

Are you buying for value or for use? Refurbishment offers a genuine value-creation route through the gap between original and renovated stock. Off-plan offers a finished product and, sometimes, appreciation between reservation and completion, but no renovation arbitrage.

They compare purchase prices and stop there. The tax difference alone is roughly 4 percentage points, and on the refurbishment side the works cost frequently equals a third or more of the purchase price. Compare total project costs, not headline prices.

They use outdated renovation figures. Given roughly 38% cost inflation since 2020, a number from even a few years ago will understate today's reality significantly. This is the single most common cause of renovation budgets going wrong before work begins.

They treat the off-plan timeline as fixed. Quoted delivery dates on this coast slip regularly. Treat the developer's figure as an optimistic case and plan around a longer one.

They skip the bank guarantee check. Spanish law requires staged payments on off-plan purchases to be secured. Not verifying that in writing is the largest avoidable risk on the entire off-plan route.

They assume planning permission is a formality. It is not, particularly in Marbella right now with the POU still being finalised. Confirm what a specific plot will actually allow before you buy it, not after.

Is it cheaper to refurbish or to buy off-plan in Marbella?

It depends on the property and the specification, but the components are clear. Refurbishment carries a lower purchase tax at 7%, plus €1,500 to €2,500 per m² in works. Off-plan carries 10% VAT plus around 1.2% stamp duty with works included in the price. On a like-for-like final result, the two often land closer together than buyers expect; the more meaningful differences are timeline and risk profile rather than absolute cost.

How long does a villa renovation take in Marbella?

Six to nine months of construction is typical for a comprehensive renovation, but twelve to eighteen months from purchase to move-in is realistic once design, licensing and inspections are included. The municipality matters, as Marbella's licensing has historically been slower than that of neighbouring town halls.

What are the risks of buying off-plan in Spain?

Principally delivery risk: delays are common and the property does not exist when you commit. Spanish law protects your staged payments through mandatory bank guarantees or insurance, which is why confirming that protection in writing before paying anything is essential. Specification disputes are the other common issue, which is why the contract rather than the renders should define what you are buying.

Can I still get planning permission to extend a villa in Marbella?

In principle yes, but the detailed rules are currently in transition. The PGOM is approved, while the POU that sets plot-level building rights is not expected to be finalised until 2027 to 2028. Any purchase that depends on future extension rights should have those rights confirmed in writing for the specific plot before committing.

Which areas are best for each route?

Refurbishment is the practical route in Sierra Blanca, the Golden Mile, Nueva Andalucía and Hacienda Las Chapas, where land is essentially built out. Off-plan supply is concentrated in Estepona and the New Golden Mile, La Quinta, Benahavís and parts of San Pedro.

Most buyers who ask us this question have already half-answered it without realising, because they have a location in mind. If that location is an established prime address, the market has effectively made the decision: refurbishment or rebuild is the route, and the real questions become budget and planning. If the location is more open, then timeline and risk tolerance decide it, and both routes are defensible.

The thing we would push back on is the idea that off-plan is the low-effort option and refurbishment the difficult one. Off-plan is lower effort during the process, certainly. But it carries a delivery risk that a finished building does not, and it requires diligence at the front end, on guarantees, on the developer's record, on the contract, that buyers frequently skip precisely because the process feels simpler. Both routes reward preparation. They just reward it at different stages.

Every version of this decision is specific to the buyer, the budget and the area. We work on both sides of it: sourcing renovation opportunities in the established areas, including properties that never reach a portal, and advising on off-plan developments where we know the developer's record rather than just their brochure.

Get in touch and tell us what you are actually trying to achieve, and we will give you an honest view of which route fits, including when the answer is that neither quite does yet.
