Buying Property in Marbella: The Complete Buyer's Guide for 2026

Buying in Marbella is not administratively difficult. Spain has a functioning land registry, a public cadastre, a notarial system and a professional legal market. What makes it risky is that those systems record different things, were updated at different times, and are rarely compared against each other unless somebody insists.

This guide walks through the whole process in the order it should happen, and flags the points where Marbella and the wider Costa del Sol throw up recurring problems.

1. Define the property and the budget

Before viewing anything, write down the non-negotiables: location, minimum bedrooms, plot or terrace, sea view or not, walkability, and whether you will renovate. Then set two budgets — the purchase price you can pay, and the total project cost you can absorb. The second is the one that matters, and it is covered in what it really costs to buy in Marbella.

2. Understand asking price versus fair value

An asking price reflects the seller's expectations. Market value reflects comparable completed sales. As-is value reflects condition. Risk-adjusted value reflects unresolved legal and planning uncertainty. Four different numbers, built four different ways — see asking price vs fair value for the method.

3. View the property properly

A viewing is a data-gathering exercise, not a romance. Photograph everything, including the things that will not appear in the brochure.

• Photograph every façade, the roof line from the garden, and the plot boundaries.
• Photograph the pool plant room, the electrical panel, the boiler and any visible plumbing.
• Look for changes in render, roof tile or floor level — they usually mark an extension or an enclosure.
• Note damp staining, cracked terraces, rusting balcony rails and pool tile loss.
• Visit twice: once in the middle of the day, once in the evening, and if possible on a weekend.
• Check road noise, neighbouring construction, and how far the sun actually reaches the terrace.

4. Request the documentation

Ask for everything in one written list, early, and treat the response as informative in itself. A seller who provides documents quickly usually has them. A seller who provides them slowly, partially, or with explanations attached often has a reason.

Our full list, with the purpose of each document, is in the documents you should request before buying.

5. Verify ownership and title

The Nota Simple is an extract from the Land Registry (Registro de la Propiedad) confirming who owns the property, how it is described, and what charges exist against it. Order a current one — not the copy the seller obtained two years ago.

• Confirm the registered owner matches the person selling, including in the case of company or inherited ownership.
• Check for mortgages, embargoes, easements and rights of way.
• Check whether the property is described as one unit or several, and whether annexes are included.
• Note the registered built area — you will need it in the next step.

6. Compare the Registry and the Cadastre

The Land Registry records legal ownership and title. The Cadastre (Catastro) records the physical and fiscal description of the property for tax purposes. They are separate systems that are updated by different events, and in older Marbella villas they frequently disagree.

Compare built area, plot area, number of units and the plan outline. Where they differ, ask why — the answer is usually an alteration that was made physically and recorded in one system, both, or neither. The mechanics of reconciling area figures are in why the square metres in a listing may be wrong.

7. Review the planning status

Ask the town hall — or your lawyer on your behalf — for the property's urban planning position: its classification, whether it complies with current planning, whether any disciplinary file is open, and what may or may not be built. Marbella has a long and well-documented planning history, and older properties can carry legacies from it.

8. Check additions and extensions

For each visible structure — extension, garage conversion, guest annexe, terrace enclosure, pergola, padel court — establish three things: does it exist physically, does it appear in the registry and cadastre, and was it licensed. Any combination other than all three is a question to resolve before you offer.

9. Review the pool and ancillary structures

Pools are the single most common undocumented structure on the coast. They are also expensive to legalise or remove. Confirm the pool appears in the cadastral plan, check for a works licence, and have the plant, liner and structure inspected — a pool that leaks into a retaining wall is a different problem from a pool that needs retiling.

10. Commission a technical inspection

An independent architect or building surveyor, instructed by you and paid by you, is the cheapest insurance in the entire transaction. Ask specifically for: structure, roof and waterproofing, damp, electrical installation, plumbing and drainage, HVAC, terraces and retaining walls, and a measured built area.

11. Estimate the renovation

Get a written range, not a number: low, expected and high. Anything that depends on opening up a wall or lifting a floor belongs in the high scenario. Our approach to building those ranges is in renovating a villa in Marbella and the true cost of buying a renovation property.

12. Understand acquisition costs

Purchase costs in Andalucía depend on whether the property is a resale or a new build, and on your personal circumstances. Andalucía applies a flat transfer tax rate on resale homes with a reduced rate for certain buyers, published by the regional government (Junta de Andalucía — Impuesto sobre Transmisiones Patrimoniales y AJD). New-build purchases are subject to VAT plus stamp duty instead. Confirm the current applicable rate for your situation with your lawyer or tax adviser before budgeting — rates and reductions change with regional budget legislation.

13. Analyse the financing

Non-resident mortgage terms in Spain are typically more conservative than resident terms, and lenders value the property themselves. Two Marbella-specific points: a bank will generally lend against the recorded, verifiable property rather than an undocumented extension, and an unresolved licence issue can stop a mortgage entirely. Variable-rate lending is referenced to Euribor, which began September 2026 clearly above 3% (euribor.com.es, 1 September 2026) — model your payment at a rate above today's, not at today's.

14. Make an evidence-based offer

Present your number with its derivation: comparable completed sales, a costed renovation range, and a list of unresolved documents with an estimated cost attached to each. Sellers dismiss opinions. They engage with evidence, and often prefer resolving a documentation issue to accepting a discount — which is a better outcome for you either way.

15. Complete professional due diligence before completion

Between reservation and notary, your lawyer confirms title, charges, debts, community status, licences and planning; your architect confirms the physical property; and any condition you negotiated is written into the private purchase contract rather than agreed verbally.

Marbella-specific problems that recur

These are common enough to check for every time, and rare enough that presenting them as universal would be wrong.

• Built-area discrepancies between listing, registry, cadastre and physical measurement — often 10% or more in older villas.
• Historic extensions added across several decades and several owners, with paperwork for some phases and not others.
• Converted lower-ground or semi-basement areas marketed as habitable space but not recorded as such.
• Pools, pool houses and outdoor kitchens with no licence and no cadastral entry.
• Terrace enclosures and glass curtains added without community or municipal permission in apartments.
• Villas built in phases where the structural, electrical and plumbing standards differ between wings.
• Renovation requirements concealed by good staging: new paint over old wiring is common.

Marbella property buyer checklist

Where BuyerWingman fits

The checklist above is the easy part. The hard part is reading twenty documents, a listing, forty photographs and three conversations and noticing that two of them disagree. That is the job BuyerWingman does: it cross-checks everything you supply, separates verified facts from seller claims, lists contradictions and missing documents, and shows the evidence behind every finding.

It is preparation for your lawyer, architect and surveyor — not a substitute for them.
