Buying Off-Plan in Spain: Payment Stages and Deposit Protection
Before choosing the finishes, understand when the money leaves your account. A practical guide to reservation payments, construction instalments and the final balance.
Read the payment plan as carefully as the floor plan.
An off-plan purchase can spread the price across reservation, contract, construction and completion. The amounts and deadlines depend on the contract. Before paying, have an independent lawyer review the developer, permits, payment account and protection for your advances; a bank financing the development is not the same as a mortgage approved for you.
How do off-plan payment stages work?
With an off-plan home, some of your money may be committed before you can walk through the finished property. The key question is both how much you pay and what has to happen before each instalment becomes due.
Request one complete schedule showing reservation, contract, construction payments and the completion balance. It should state whether earlier payments are credited towards later totals, when applicable taxes are payable and which deadlines are fixed dates or construction milestones.
If a brochure says “20% on contract”, ask whether that includes a reservation already paid. This small clarification prevents a large misunderstanding when you organise transfers.
A €300,000 payment journey
An invented example to show the arithmetic, not a standard Spanish payment plan.
Total price: €300,000. Paid before completion: €90,000. The €6,000 reservation is included in the price. Taxes and other acquisition costs are excluded. Actual contracts may use very different percentages and deadlines.
What should protect the money you pay early?
Spain’s Building Act sets out protection for qualifying advance payments on homes under construction. Its first additional provision addresses bank guarantees or surety insurance, with the guarantee obligation linked to obtaining the building permit, and a dedicated account for the advances.
Ask your lawyer to confirm how the rules apply to the project and each payment. Request the buyer-specific guarantee or insurance documentation, identify the home it covers and reconcile the protected amounts with the contract and receipts.
A sales brochure mentioning “bank guarantees” is not the same as having the appropriate documentation for your own purchase. Check the beneficiary, issuer, coverage and claim conditions before money is due.
Before each payment, check this
| Stage | Documents and questions | Budget check |
|---|---|---|
| Reservation | Who receives the funds? What is reserved? What are the return conditions? | Confirm whether it is credited towards the price. |
| Private contract | Independent review of title, permits, specification, delivery terms and advance protection | Record all amounts and tax payment dates. |
| Construction instalment | Evidence relevant to the agreed milestone, payment instructions and applicable cover | Check the amount against your running total. |
| Completion | Lawyer’s review of completion and occupation documentation, title and any charges; property inspection | Reconcile previous payments, the final balance and any mortgage funds. |
Four details that deserve a second look
The completion date
Separate a target date in marketing from the contractual delivery commitment. Ask your lawyer to explain extensions, delays and the agreed remedies.
The specification
Keep the signed specification alongside the floor plan. Record what is included, what is an upgrade and how substitutions or changes are handled.
The account details
Verify the receiving account through a known contact channel before a transfer. Treat a last-minute email changing bank details as something to check independently.
The handover
Arrange an inspection and record defects. Agree how issues will be documented and followed up, and have your lawyer explain any consequences for completion.
Will the mortgage cover the final payment?
Do not build the plan around an unconfirmed future mortgage. The lender will need to assess you and the property, and your financial situation may change while construction progresses.
In our example, a €210,000 completion balance happens to equal 70% of the price. That does not mean a bank will lend that amount. Ask how you would complete if the approved loan were smaller or the valuation lower than expected.
Banco de España explains that a buyer may consider a new mortgage or taking over the relevant part of the developer’s loan. Taking over that loan still requires the bank’s approval. Compare the actual conditions and costs rather than assuming the developer’s bank is the simplest or cheapest option.
Your questions, answered
Is there a standard off-plan deposit in Spain?
No single percentage should be assumed from this guide. Read the project’s proposed schedule and negotiate with advice before committing. The chart is an illustrative example.
Are taxes included in the advertised instalments?
Check the contract and invoices. The example here excludes taxes and fees so that the price instalments can be understood separately.
Does the developer’s bank loan protect my purchase automatically?
Do not make that assumption. Your lawyer should verify the protection for your advance payments and the documents identifying your purchase.
Is this the same decision as new build versus resale?
It is one part of it. For the broader choice of property type, condition and timing, read HomeSee’s existing comparison before examining an individual development.
A new home starts with a clear schedule.
Compare the property itself and the cash commitment together. Keep room in the plan for the final acquisition costs, furnishing and the first months of ownership.
