Buying Off-Plan on the Costa del Sol: Payment Schedules, Bank Guarantees and Real Timelines (2026)
When you buy off-plan in Spain, you pay in stages before the building exists. The standard schedule runs: a reservation fee of €3,000-10,000, then 20-30% at private purchase contract, then the remaining 70-80% at notarial completion (escritura) when you collect the keys. Every euro paid before completion must be backed by a bank guarantee or insurance policy under Spanish law. Here is how it works in practice, what the law requires, and where British buyers tend to lose money.
What is the typical off-plan payment schedule in Spain?
The schedule varies between developers, but the structure is nearly always the same on the Costa del Sol:
| Stage | When | Typical amount | What happens |
|---|---|---|---|
| Reserva (reservation) | At property selection | €3,000-10,000 | Takes the unit off market; usually non-refundable if you pull out without a legal cause |
| Contrato privado (private contract) | 4-12 weeks after reservation | 20-30% of purchase price minus reservation fee | Legally binding; fixes completion date, sets penalty clauses |
| Pagos a cuenta (stage payments) | At construction milestones | 0-20% additional | Not all developers require these; your contract will specify |
| Escritura (completion) | When occupation licence is granted | Remaining balance | Bank mortgage released here; all taxes and fees due at this point |
On a €350,000 apartment where the developer requires 30% at contract, that means €105,000 due before a single brick is laid, plus your reservation. Add 11.2% in taxes and fees (IVA 10% + AJD 1.2% for new-build in Andalusia) on top of the full purchase price, and you need roughly €144,000 in liquid cash before your mortgage lender releases a penny.
For a non-resident British buyer with a 65% LTV mortgage on that same €350,000 property:
- Stage payments already paid: €110,000 (reservation + 30% at contract)
- Mortgage (65% LTV): €227,500
- Taxes and fees at completion: approximately €39,200
- Total cash required from your own pocket: roughly €149,200
This is structurally different from buying a resale, where all the cash leaves your account on one day. Off-plan spreads the outlay over 24-42 months but adds currency exposure on every individual payment.
Are off-plan stage payments protected if the developer goes bust?
Yes, and this is the non-negotiable piece. Under Spanish law, every stage payment you make before completion must be insured. This obligation originated in Ley 57/1968 and is now embedded in the wider insurance regulatory framework under Ley 20/2015 de 14 de julio. The developer cannot legally demand a stage payment without first providing you with either:
- An aval bancario: a bank guarantee issued by a Spanish credit institution on behalf of the developer, or
- A seguro de caución: an insurance policy from a licensed Spanish insurer
Both protect the same thing. If the developer enters administration, abandons the project, or fails to complete, you can reclaim all your stage payments in full, including statutory interest.
The guarantee must be in your name individually. A developer showing you a single blanket policy covering the entire development is not sufficient. You are entitled to an individual guarantee document for each payment you make.
Your Spanish abogado should obtain and verify these documents before any transfer leaves your account. If a developer says the guarantee is “in progress” or will arrive “after the next payment,” do not send the money. The legal obligation is theirs to fulfil first.
What is the Seguro Decenal, and is it compulsory?
The Seguro Decenal is separate from the stage-payment guarantee. It is a 10-year structural defect warranty required by Article 19.1.c of the Ley de Ordenación de la Edificación (LOE 38/1999). It covers:
- Structural failure: foundations, load-bearing walls, beams, slabs, or anything affecting the integrity of the building
- Duration: 10 years from the date the occupation licence (licencia de primera ocupación) is granted
It does not cover cosmetic defects (cracked plasterwork, sticking doors), fit-out failures (appliances, floor finishes), or any damage caused after handover by the owner.
If you are buying as an investor, the developer cannot waive the Seguro Decenal under Article 19.2. If someone suggests you skip it to reduce paperwork, that is a serious red flag. Insist on seeing the policy number and underwriter name before you sign anything.
How long does off-plan actually take on the Costa del Sol?
Most British buyers are quoted 24 months and end up waiting 30-42 months. Here is the realistic phase breakdown for a Costa del Sol apartment complex in the current planning environment:
| Phase | Realistic duration |
|---|---|
| Licencia de obras (planning permission) | 3-12 months from developer’s land purchase |
| Foundation and structure | 8-12 months |
| Interior fit-out, common areas, landscaping | 8-12 months |
| Licencia de primera ocupación (occupation licence) | 2-6 months post-construction sign-off |
| Escritura and key handover | 4-8 weeks after occupation licence |
| Reservation to keys, realistic total | 30-48 months |
The licencia de obras stage is where most delays accumulate. Junta de Andalucía processing times for larger residential projects have been running at 6-15 months in recent years, and any revision to plans resets the clock. If a developer’s brochure states “completion Q4 2027,” build in at least 6-12 additional months before you commit a specific life event to that date.
What does your contract say about delays?
Off-plan contracts on the Costa del Sol commonly contain one of three approaches to delays:
- A fixed completion date with defined penalty payments if the developer overruns
- An “esencial” clause, making the delivery date an essential contractual term you can cancel on if it is missed
- A “razonable” clause, allowing the developer an unspecified “reasonable” extension without penalty
Most developer-drafted contracts use option 3. Before you sign, instruct your abogado to negotiate a defined delay period (six months is common) after which you can elect to cancel and recover all payments plus interest at the Bank of Spain reference rate. Once you have exchanged contracts, you have very little leverage on this point.
What are the total costs on top of the off-plan price?
For a new-build purchase in Andalusia, here is the full cost stack on a €350,000 apartment:
| Cost | Rate / Worked amount |
|---|---|
| IVA (VAT on new residential property) | 10% = €35,000 |
| AJD (Stamp Duty, Andalusia) | 1.2% = €4,200 |
| Notary fees | €800-1,500 |
| Land Registry | €400-900 |
| Mortgage arrangement costs (if applicable) | €500-1,500 |
| Spanish abogado | €2,000-4,000 |
| Total additional costs | ~€42,900-47,100 |
The taxes (IVA + AJD = 11.2% on €350,000 = €39,200) represent the bulk of this. They are due at the escritura, not during the construction phase, so they do not appear in your stage-payment schedule. But you need to have them ready and in euros at completion. See the full cost breakdown for buying on the Costa del Sol for worked examples at other price points.
On currency: if you are transferring from sterling, you are making multiple separate GBP/EUR conversions across 2-4 years. The reservation and private contract payments happen early in the cycle; the large completion balance arrives at the end. A forward contract on the completion balance, fixed as soon as you know the amount and date, protects your budget against exchange rate movement. Our currency hedging guide explains how forward contracts work and which FCA-authorised brokers to use.
Can I get a Spanish mortgage for an off-plan property?
Yes, but the timing works differently from a resale purchase. Spanish banks do not issue a formal mortgage offer (FEIN, Ficha Europea de Información Normalizada) until the property exists as a completed, valued asset. The practical sequence:
- Before signing the private contract: Get a mortgage in principle (pre-approval) from a Spanish lender or specialist broker. This confirms your borrowing capacity but is not a binding offer.
- During construction: Fund your stage payments from savings. No mortgage draws down at this stage.
- 2-4 months before estimated completion: Start the formal mortgage application. Your broker commissions a tasación (official valuation) on the nearly-finished property.
- On approval: The FEIN is issued. You have a mandatory 10-day cooling-off period before you sign the mortgage deed.
- At escritura: Mortgage funds are released simultaneously with your completion balance.
Non-resident British buyers currently qualify for 60-70% LTV on Spanish new-build (Banco de España guidance, 2026). The remainder comes from your own savings, plus you need cash reserves for the taxes and fees above. See the Spanish mortgage guide for non-residents for the full documentation checklist and current rate comparisons.
Can I sell my off-plan contract before the property completes?
Yes. This is called a cesión del contrato (assignment of contract). You transfer your contractual rights to a third-party buyer before completion; they take on the obligation to complete and pay you an assignment fee for the position you have built up.
Key points to understand before attempting this:
- Developer consent: Most off-plan contracts require the developer’s written approval for any assignment. Some charge a 1-3% assignment fee to the original buyer. Read your contract.
- Tax: If the assignment price exceeds what you paid in stage payments, the profit is subject to Spanish IRNR capital gains tax at 24% for UK non-residents (post-Brexit rate). You need to file and pay in the year of the assignment, not at your eventual completion date.
- Documentation: Your abogado should draft the cesión agreement and confirm the developer conditions before you agree a price with any prospective assignee.
Assignment is most common when a buyer’s circumstances change before completion (job loss, divorce, or a decision to downsize) and a full withdrawal would mean forfeiting the 20-30% arras deposit. It preserves most of the capital you have put in, provided there is a buyer willing to pay for the position.
The 10 questions to ask before signing an off-plan contract
Before you commit a single euro, get written answers from the developer’s representative and have your abogado verify them:
- Is the licencia de obras already granted, or is it pending? If pending: what is the expected timeline and what happens to your reservation if it is refused?
- What individual bank guarantee or insurance policy (aval or seguro de caución) covers each of my stage payments, and when will I receive the documentation?
- What is the fixed completion date, and what delay remedy do I have if the developer overruns?
- What stage-payment schedule applies, and on what specific construction milestones are payments triggered?
- Does the final headline price include IVA and AJD, or are these charged on top?
- Who is the Seguro Decenal underwriter, and what is the policy number?
- What are the developer’s conditions for assignment (cesión del contrato), and what fee do they charge?
- Can I instruct an independent architect or surveyor to inspect the property before I sign the escritura?
- What community fees are estimated for the completed development, and are there any known derrama (special assessments) planned?
- What is the developer’s track record on the Costa del Sol? How many projects have they delivered, on time, in the last five years?
Your Spanish property lawyer should be able to obtain answers to questions 2, 3, 6 and 7 directly from the draft contract before you are asked to sign anything.
Is off-plan worth it for British buyers in 2026?
The case for off-plan is real. Buyers who reserved Costa del Sol apartments at 2021 prices and completed in 2024-2025 saw substantial capital growth before they had even moved in. A €350,000 reservation price in an area that subsequently re-priced at €420,000 by completion represents a meaningful uplift on the stage-payment cash deployed.
But the risks are not trivial: construction delays, currency moves across a 3-year payment window, and the complexity of securing a mortgage at completion all require more planning than a straightforward resale purchase. Weigh both sides carefully. The new-build vs resale ROI guide runs the numbers on each scenario, including the tax difference (11.2% for new-build vs 7% ITP for resale) and the effect on net return.
If you are at the stage of evaluating a specific Costa del Sol development, get in touch and tell us which one. We can check the developer’s completion record, verify the guarantee documentation, and tell you whether the asking price matches current comparables in the area. That conversation costs nothing.
