How long does the off-plan purchase process take from reservation to completion?
The typical off-plan purchase timeline is 18–36 months from reservation to key handover. Boutique developments can complete in 12–18 months; large coastal developments typically take 24–36 months. The target completion date is set by the developer and stated in your purchase contract.

- 2Construction phase: 12–30 months depending on development scale
- 3Pre-completion snagging inspection: 4–8 weeks before handover
- 4Notary signing and key handover: 1–3 days after snagging sign-off
- 5Land Registry registration: 2–6 weeks after notary
- 6Most contracts include a longstop date — typically 6–12 months beyond the target completion
Key Takeaways
- Payment schedule typically splits across reservation, exchange (10%), staged payments (20–30%), and balance at completion (60–70%)
- All stage payments during construction must be covered by a bank guarantee
- Lock in your completion funds exchange rate early — currency risk over 2+ years is significant on large purchases
When you buy off-plan in Spain, you are purchasing a property that does not yet exist in its final form. From the moment you pay your reservation deposit to receiving your keys, a typical timeline is 18 to 36 months. This timeline is determined by the construction programme and is stated in your purchase contract with a target date and a longstop date.
Stage 1: Reservation (Week 1)
You select a specific unit and pay a reservation fee — typically €6,000–€10,000 — to remove the property from sale while legal due diligence is conducted. This is usually refundable if your solicitor finds a legal issue, but non-refundable if you simply change your mind after contracts are issued. Always clarify refund terms in writing before transferring funds.
Stage 2: Private Purchase Contract (Weeks 4–8)
Your solicitor reviews all developer documentation — title, planning permits, architect's certificate, bank guarantee arrangements, and community rules. You sign a Private Purchase Contract (Contrato de Compraventa or Contrato de Arras) and pay the first major tranche — typically 10% of the purchase price minus the reservation fee already paid. This is the binding commitment.
Stage 3: Construction Stage Payments (Months 2–30)
Depending on the development structure, the developer may request additional payments as construction milestones are met — typically 10–30% of the total price across key phases. Every payment must be covered by a bank guarantee (Aval Bancario). This guarantee is your legal entitlement to a full refund if the developer fails to complete.
Stage 4: Snagging Inspection (4–8 Weeks Before Completion)
Before completion, your solicitor or an independent snagging inspector conducts a thorough inspection of the finished property. Any defects are documented in a lista de reparos and the developer is obligated to rectify material issues before handover, or address minor ones under the 10-year structural warranty (seguro decenal).
Stage 5: Notary Signing and Key Handover (Completion Day)
On completion day, all parties sign the Escritura de Compraventa — the final title deed — before a Notary. The balance payment (typically 60–70% of the purchase price) is paid on this day along with all taxes and fees. You receive the keys. The property is subsequently registered at the Land Registry within 2–6 weeks.

Common Mistakes to Avoid
A UK buyer reserves a 2-bed apartment in Estepona in January 2024 for €380,000. Timeline: reservation January 2024, contracts signed March 2024 (€38,000 payment), construction stage payment September 2024 (€19,000), completion Q1 2026 (balance €285,500 + taxes/fees ~€50,000). Total liquid funds needed: approximately €335,500.
A bank guarantee (aval bancario) is a legal commitment from a Spanish bank to refund a buyer's stage payments if the developer fails to complete the property within the agreed timeframe or becomes insolvent. It is a mandatory legal requirement for all off-plan property purchases in Spain under Ley 57/1968 (updated 2015). Bank guarantees should be obtained for each stage payment individually.
