How to Research a Developer Before Buying Off-Plan in Marbella

Off-plan purchases carry developer risk. Here is how to assess a developer's track record before you commit your deposit.

Buying off-plan in Marbella means committing a significant deposit to a project that does not yet physically exist, from a developer whose reliability and financial health you may not know well. When it works, off-plan purchases are excellent: you buy at early-stage pricing, the property is built to your specification, and you complete into a property that is worth more than you paid for it. When it goes wrong, the process of recovering your deposit, even with bank guarantee protection, is slow and stressful.

Buying property in Marbella off-plan with proper developer research is substantially lower risk than buying blind. Here is what to look at.

Track record of completed projects

The most important thing to check is what the developer has actually built and delivered. Ask the developer or their sales team for a list of completed projects. Then go and look at them. Visit completed developments from the same developer, talk to residents if you can, and assess whether the delivered quality matches the materials and specifications promised at the sales stage. Reputable developers are proud of their track record and will facilitate this. Developers who become evasive when asked about previous projects are a concern.

Online reviews of specific developments exist on Google Maps, Tripadvisor for hotels that developers also own, and property forums. Search specifically for the developer name and any of their past projects to find unfiltered buyer feedback.

Financial health

A developer can have a good track record and still encounter financial difficulties. The Spanish property market has produced numerous situations where developers with good intentions ran out of money mid-project, leaving buyers with incomplete properties and a slow legal recovery process. Checking a developer's financial health is harder than checking their track record, but some basics help.

Companies registered in Spain (SL or SA) file annual accounts with the Registro Mercantil. These are public and searchable online. The accounts will show whether the company is profitable and what its debt position looks like. For larger developers, credit ratings and news coverage (in Spanish business press such as El Confidencial or Expansion) may give additional colour.

Bank guarantees

Spanish law requires developers to protect off-plan deposits with bank guarantees or insurance policies. Ask specifically which bank is providing the guarantee, confirm the guarantee covers your deposit from the moment it is paid, and have your lawyer verify that the guarantee is correctly structured and would be enforceable if needed. The bank guarantee is the floor of protection, not the ceiling; developer track record and financial health are the additional layers above it.

Legal structure of the purchase

Your lawyer reviews the off-plan purchase contract before you sign. Key things they check: that the developer holds the necessary planning permissions for the specific development being sold, that the bank guarantee is properly documented, that the construction timeline commitments are clear, that the specification is detailed enough that disputes about what was promised become less likely, and that there are penalty provisions if the developer delivers significantly late.

Site visits during construction

For off-plan purchases where construction is underway, periodic site visits are worthwhile. A developer who is progressing on schedule and maintaining quality during construction is doing so consistently, not just at handover. If access to the site during construction is refused without clear safety reasons, that is worth noting.

The professional team

Beyond the developer, check who else is involved. Spanish law requires an aparejador (building supervisor) on every construction project. Ask who the project architects are and look up their prior work. Ask who is providing the build guarantee insurance (seguro decenal), which is mandatory for new builds in Spain and covers structural defects for ten years.

Frequently Asked Questions

What is a bank guarantee for off-plan property in Spain?

A bank guarantee (or equivalent insurance policy) is legally required to protect deposits paid for off-plan properties in Spain. If the developer fails to complete the project, the buyer can claim back their deposit plus interest under the guarantee. The guarantee must be from a qualified financial institution and must cover the deposit from the date it is paid.

How can I check a Spanish developer's financial status?

Companies registered in Spain file annual accounts with the Registro Mercantil, which are publicly accessible online at registradores.org. The accounts show revenue, profit, and debt. For larger developers, Spanish business press coverage provides additional context. Your lawyer can also assist with due diligence on the developer entity.

What is the seguro decenal for new builds in Spain?

The seguro decenal is mandatory ten-year structural warranty insurance for new residential buildings in Spain. It covers defects in the structural elements of the building (foundations, load-bearing walls, structure). When buying a new build, confirm this insurance is in place and get the certificate at completion.
