Buying a new build off plan on the South Costa Blanca is a very different process from buying a finished resale. You are committing to a home that does not exist yet, paying in stages while it is built, and trusting the developer to deliver on time and to spec. For expat families relocating from the UK, Scandinavia, Germany, the Netherlands or Russia, the off plan route in Torrevieja, Orihuela Costa, Villamartin, La Zenia and Pilar de la Horadada is hugely popular, because it secures a modern, energy efficient home with a pool. This guide walks through how the process works in 2026 and where families get caught out.

What Off Plan Actually Means Here

Off-plan means you sign a private purchase contract with the developer for a home that is still under construction, or not yet started, and pay in installments tied to building milestones.

• You reserve a specific plot or unit at a launch price, often before competitors see it
• You usually choose finishes, kitchen layout and sometimes the position within the development
• New builds on the South Costa Blanca are built to the current Codigo Tecnico de la Edificacion, so insulation, glazing and energy efficiency are far ahead of older resales
• The trade off is time, a typical off plan in this area completes 12 to 24 months after reservation

The Payment Stages You Will Actually Pay

Off plan is paid in tranches, not in one lump at the end. The exact split varies by developer, but the South Costa Blanca pattern is consistent.

• Reservation deposit to take the unit off the market, often 3,000 to 10,000 euros
• Private purchase contract within a few weeks, typically bringing you up to around 20 to 40 percent of the price plus IVA
• Interim stage payments during construction, linked to milestones such as foundations, structure and roof
• Final balance at the notary on completion, when the property is finished and the deed is signed
• IVA on a new build is 10 percent, and AJD stamp duty on the new build deed dropped to 1.4 percent in the Comunitat Valenciana from 1 June 2026

Bank Guarantees Are Not Optional

This is the single most important protection in an off plan purchase, and the one expat families most often fail to check. Spanish law requires the developer to guarantee every euro you pay before completion.

• Under the building law framework, every stage payment must be secured by a bank guarantee or insurance policy in your name
• If the developer fails to deliver or goes insolvent, you reclaim your staged payments plus legal interest
• Stage payments are paid into a dedicated, ring fenced account, not the developer's general account
• Ask for the individual guarantee certificate for each payment, in your name, before you transfer anything

No guarantee, no payment. If a developer cannot produce one, that is a stop sign, not a negotiating point. The wider framework sits within the Ley de la Vivienda de la Comunitat Valenciana and national building legislation.

The Licence of First Occupation

A new build is not legally habitable until it has its occupation licence. On the South Costa Blanca this is the licencia de primera ocupacion, or in many cases now a declaracion responsable de primera ocupacion lodged with the ayuntamiento.

• It confirms the finished building matches the approved project and the original works licence
• You need it to legally connect mains water and electricity in your own name
• Without it, you cannot get permanent utility contracts, only temporary builder supply
• Do not complete at the notary on the strength of a promise that the licence is coming, get confirmation it is in hand

Due Diligence Before You Reserve

Off plan due diligence is about the developer and the land as much as the home itself.

• Check the developer's track record, how many completed schemes they have delivered locally in Orihuela Costa, Villamartin or Pilar de la Horadada
• Confirm the land has the building licence already granted, not merely applied for
• Pull the nota simple from the land registry to verify ownership and any charges, sourced via Registradores de Espana
• Read the private contract for the completion date, the penalty if the developer is late, and exactly what finishes are included
• If the development has a comunidad de propietarios in formation, ask for the AGM minutes once one exists, since the actas are the buyer side document that show what has been agreed

Snagging and Handover

When the developer says the home is ready, you do not simply collect keys. You inspect first.

• Carry out a snagging inspection before signing the deed, listing every defect from tiling to taps to paintwork
• Many families bring an independent snagging surveyor, well worth the modest fee on a 300,000 euro purchase
• New builds carry statutory warranties, including cover for structural defects for ten years
• Keep the contractor on the hook for snag fixes, it is far easier to resolve them before final payment than after

Completion and Registration

Completion happens at the notary, where you pay the final balance and sign the escritura. The job is not finished there.

• Your lawyer pays the IVA and AJD and lodges the deed at the Registro de la Propiedad
• Registration in your name is what makes you the legal owner on the public record, not just the notary signing
• A brand new build will not yet have a valor catastral assigned, so your first IBI bill follows once the cadastre catches up
• Set up your permanent water and electricity contracts once the occupation licence is confirmed

Common Mistakes

• Paying a stage instalment before the matching bank guarantee certificate is in your name
• Assuming the glossy show home finish is what your unit gets, rather than checking the contract specification line by line
• Completing before the licence of first occupation is genuinely issued, then being stuck on temporary builder utilities
• Skipping the snagging inspection and signing the deed with defects unrecorded
• Budgeting only the headline price and forgetting the 10 percent IVA plus AJD and lawyer fees on a new build
• Treating the developer's in house lawyer as your lawyer, they act for the developer, you need your own independent representation

A Practical Sequence

• Get your NIE and a Spanish bank account in place early, before you reserve
• Appoint your own independent lawyer, not the developer's, to review the contract and hold the guarantees
• Check the developer's local delivery record and confirm the building licence is granted
• Sign the private contract only once each stage payment is covered by a bank guarantee in your name
• Track construction milestones and pay each tranche against its guarantee, never ahead of it
• Snag the property, confirm the occupation licence, then complete at the notary and register the deed
