A polished show flat, sea views from a roof terrace and a completion date two years away can make an off-plan purchase in Spain feel wonderfully straightforward. It is not. The best checks for off plan property happen before any reservation fee leaves your account, when there is still time to question the paperwork, the promoter and the promises being made.
For international buyers, the attraction is clear: a brand-new home, modern energy standards, staged payments and often a choice of layout or finishes. But you are buying a legal right to a future property, not simply inspecting the home that exists today. That makes disciplined due diligence essential.
1. Confirm who owns the land and has the right to build
Start with the plot itself. The developer should either own the land or hold a properly documented right to develop it. An official Land Registry extract, known as a nota simple, helps confirm ownership, registered charges, mortgages, easements and other rights affecting the site.
This is not a box-ticking exercise. A plot can look ready for construction while carrying a charge that needs to be released, or while being held by a company different from the one asking you to sign the reservation agreement. Your legal adviser should establish the relationship between the landowner, the developer and any finance provider before you commit.
Ask, too, whether the planned boundaries, access roads, communal areas and parking match the marketing material. A beautiful computer-generated plan is not proof of legal reality.
2. Check the planning position and building licence
A developer needs the appropriate urban-planning permissions before building can lawfully proceed. In practical terms, buyers should verify that the development has the required building licence and that the project being sold corresponds to the approved plans.
Planning matters particularly in Valencia, the Costa Blanca and other fast-moving coastal markets, where a project may be marketed at an early stage. Marketing before construction is not automatically a warning sign, but a buyer should understand exactly which permissions are in place and which remain pending.
Your adviser should also examine the planning classification of the land and any conditions attached to the licence. A promised pool, commercial unit, landscaped area or view can be affected by planning decisions beyond the walls of your own home. If your purchase depends on a particular feature, have it documented rather than relying on a sales conversation.
3. Investigate the developer, not just the development
A strong brand presentation does not tell you whether the developer has the financial capacity and operational experience to finish the scheme. Look at the company behind the brochure: its legal identity, previous developments, delivery record and any signs of financial distress.
Ask who is constructing the project and whether the builder has experience with comparable schemes. A smaller developer is not necessarily a poor choice, just as a large one is not automatically risk-free. The relevant question is whether the parties involved have the resources, track record and contractual structure needed to deliver what is being promised.
It is also sensible to visit completed projects where possible. The quality of common areas, finishes and after-sales response can reveal far more than a showroom sample board. This is where local, buyer-side representation earns its place: someone should be testing the story being sold, rather than repeating it.
4. Protect every stage payment with the right guarantee
This is one of the most important checks for off-plan homes in Spain. Amounts paid towards a new-build property before completion should be protected in accordance with the applicable Spanish consumer-protection rules, typically through an individual bank guarantee or insurance policy linked to your payments.
Do not assume that a sentence in the contract is enough. Check who provides the guarantee, what payments it covers, the property it identifies and the conditions for claiming it if the development is not completed or delivered as agreed. Obtain the relevant documentation for each payment and keep it safely with proof of transfer.
The payment schedule itself deserves scrutiny. It should be clear, proportionate and tied to the contract, not improvised through requests from a sales office. Never pay a substantial sum simply because you have been told that other buyers are doing the same.
5. Read the reservation and purchase contracts as business documents
Reservation agreements are often treated as a formality. They are not. They can set the tone for the entire transaction, identify the property, define the deadline for signing the private purchase contract and state what happens to your money if conditions are not met.
Before signing, make sure the unit, storage room, parking space and any private garden or terrace are described accurately. Check the purchase price, VAT treatment, payment dates, completion deadline and the circumstances in which you may recover your deposit.
The private purchase contract should go further. It needs clear obligations for both buyer and developer, a long-stop completion date, remedies for unjustified delay and a precise description of what is included. If the developer may make changes, the permitted scope should be tightly defined. Minor technical adjustments can be reasonable; a material reduction in quality, size or amenity is another matter.
A contract is also where language matters. If you do not read Spanish fluently, do not rely on a quick explanation at the point of signature. Obtain independent legal advice and a clear translation of the commitments you are making.
6. Compare the specification with what you are actually buying
Off-plan marketing sells a lifestyle. Your contract must sell you a specification. Request the memoria de calidades, the formal quality specification, and read it closely alongside the floor plan and sales materials.
Look for details that change value and liveability: flooring, glazing, air conditioning, kitchen appliances, insulation, hot-water systems, sanitaryware, lift access, storage, communal facilities and landscaping. Terms such as “or similar” are common, but they should not give the developer unlimited freedom to substitute cheaper materials.
Square metres need care as well. Establish whether figures refer to built area, usable internal area, terraces, communal allocations or a combination of these. A large advertised number can include walls and shared elements. For a buyer comparing homes across countries, that distinction can be surprisingly significant.
7. Establish the true purchase cost and future running costs
The headline price is only the beginning. New-build purchases normally involve VAT and documented legal acts tax, alongside legal fees, notarial and registry costs, mortgage costs where relevant, and practical expenses such as furnishing and connection charges.
Ask for a written estimate based on your specific purchase. It should distinguish mandatory taxes from optional services and identify whether any stated price excludes parking, storage or upgrades.
Then look beyond completion. Community fees, municipal property tax, waste charges, insurance and maintenance costs can affect the long-term appeal of a second home or investment. A development with extensive gardens, security, lifts and pools may be attractive, but it will need a realistic annual budget.
8. Check how completion, inspection and handover will work
A completion date should not be a vague aspiration. Understand the contractual deadline, the circumstances that may justify an extension and what evidence the developer must provide when the home is ready.
Before signing at the notary, the property should be inspected carefully. This is your opportunity to identify defects, incomplete works and deviations from the agreed specification. Create a written snagging list supported by photographs, and agree how and when issues will be corrected.
You should also confirm that the documentation needed for lawful occupation and connection of utilities is in place. Depending on the property and region, this includes the first occupation documentation and the records necessary for registration and practical handover. Do not let a key handover become a substitute for proper verification.
9. Review the community and the wider setting
You are not only buying four walls. You are joining a community and committing to a location that may still be changing around you. Review the proposed community rules, estimated budgets and the division of communal elements. If short-term lets, pets, commercial use or renovation plans matter to you, understand the rules early.
Examine the area beyond the site boundary too. Planned roads, nearby plots, flood considerations, rail routes and future construction can materially alter noise, privacy, access and views. This is especially relevant where buyers are drawn to a view that has not yet been tested from a finished home.
10. Keep independent professionals on your side
The developer’s sales team can be helpful, but it works for the developer. Its role is to sell the project, not to provide independent legal or technical advice to you. Protecting your position means appointing professionals whose duty is to the buyer.
For many international purchasers, the most effective approach combines a Spanish property lawyer with independent technical input where the project warrants it, plus a buyer-side adviser who can co-ordinate the process and challenge unclear answers. HelloHome Valencia supports buyers in this way: by checking the detail behind the promise and keeping each decision focused on the buyer’s interests.
An off-plan home can be an excellent route to a new life in Spain, particularly when the location, developer and contractual protections all stand up to scrutiny. The confidence to proceed should come from evidence, not from a launch-day discount or a reassuring brochure.
