New builds on the Costa Blanca: keys to buying off-plan

Buying off-plan gives access to new product with a staged payment calendar and room for customisation, but demands verifying guarantees.

The bank guarantee, non-negotiable

By law (Law 20/2015), every amount paid on account must be guaranteed by a bank or insurer. Demand the individualised guarantee for each payment: if the developer fails to deliver, you recover 100% plus interest.

Typical milestones

• Reservation: €6,000–20,000
• Private contract: 10-20%
• During construction: 10-20% at certifications
• Deed: the rest, usually with a mortgage

Real customisation

Until the structure closes you can usually modify layouts; finishes, until 8-10 months before delivery. Every change in writing and priced.
