Buying an off-plan property on the Costa Blanca remains one of the most attractive options for those looking for a permanent residence, a holiday home or a real estate investment. Alicante offers a wide range of new developments in locations such as Orihuela Costa, Torrevieja, Guardamar del Segura, Santa Pola, Alicante, Benidorm, Finestrat, Calpe, Jávea, Dénia and Rojales, where new residential projects with excellent specifications and prime locations are launched every year.

However, purchasing a property before construction is completed requires understanding both the advantages and the potential risks, as well as the legal protections available. This guide explains everything you need to know to make an informed decision.

What Does Buying an Off-Plan Property Mean?

Buying off-plan means purchasing a property while it is still in the planning or construction phase. The buyer signs a purchase agreement with the developer and makes staged payments as construction progresses until the property is completed and handed over.

This option allows buyers to secure a brand-new home at an early stage, often at a more competitive price, while also benefiting from the possibility of personalising certain features.

Difference Between an Off-Plan Property and a Completed New-Build Home

The main difference lies in the stage of construction.

With an off-plan property, the home is not yet finished, and completion may take between 12 and 30 months, depending on the development.

A completed new-build property, on the other hand, already has its occupancy licence and can usually be completed and handed over immediately.

Benefits of Buying an Off-Plan Property

Purchasing a property during the early stages of a development offers several advantages for both domestic and international buyers.

Lower Purchase Price at the Time of Reservation

Developers often launch new developments with introductory prices to encourage early sales.

This allows buyers to purchase at a price that is often lower than the property's market value once construction has been completed.

In addition, buyers may benefit from any increase in property values during the construction period.

Opportunity to Personalise the Layout and Finishes

Depending on the stage of construction, many developments allow buyers to choose:

  • Flooring and wall finishes.
  • Interior doors and carpentry colours.
  • Kitchen worktops and cabinetry.
  • Bathroom fittings.
  • Certain layout modifications.

This level of customisation enables buyers to tailor their new home to their personal preferences before moving in.

Capital Growth Before Completion

In high-demand areas such as the Costa Blanca, property values often increase while developments are under construction.

If the project sells well and the market continues to grow, the property's value may already have risen before the keys are handed over.

This makes off-plan purchases particularly attractive for medium-term investors.

Risks of Buying Off-Plan: What You Should Know

Although today's legal protections are much stronger than in the past, buyers should still be aware of certain risks.

Construction Delays and How to Claim Compensation

Construction projects may be delayed due to:

  • Material supply issues.
  • Weather conditions.
  • Administrative procedures.
  • Technical construction challenges.

It is essential to review the purchase contract carefully, paying particular attention to:

  • The estimated completion date.
  • Permitted delay periods.
  • Compensation clauses.
  • Circumstances considered acceptable causes for delay.

If the developer fails to meet the agreed completion date without legal justification, buyers may exercise the rights established in the contract and applicable legislation.

Changes to the Project or Specifications

Occasionally, technical or administrative reasons may require changes to the original project.

However, such changes must respect the essential terms of the contract and cannot significantly reduce the promised quality without proper justification.

For this reason, buyers should keep copies of all brochures, floor plans, specifications and contractual documents.

Developer Insolvency: How Your Payments Are Protected

One of the biggest concerns when buying off-plan is the possibility that the developer may fail to complete the project.

Spanish legislation protects buyers' advance payments through a bank guarantee or a surety insurance policy, provided the legal requirements are met.

These guarantees offer significant financial protection if the development cannot be completed.

Legal Guarantees When Buying Off-Plan Property in Spain

Spain has a robust legal framework designed to protect buyers of properties under construction.

Bank Guarantee and Surety Insurance

Advance payments made during construction must be secured by either:

  • A bank guarantee.
  • A surety insurance policy.

If the property is not completed or is not delivered within the legally established conditions, buyers may be entitled to recover the amounts paid in accordance with Spanish legislation.

These guarantees provide a high level of legal security throughout the purchasing process.

Law 20/2015 on the Regulation of Private Insurance

Law 20/2015 strengthened the protection system for advance payments made when purchasing off-plan properties.

Under this legislation, buyers have legal mechanisms to recover their funds when the conditions established by law apply, provided that payments have been made in accordance with the applicable regulations.

Steps to Buying an Off-Plan Property on the Costa Blanca

Before signing any contract, buyers should carry out several important checks.

Verify the Building Licence and Technical Specifications

It is advisable to request:

  • Building licence.
  • Approved architectural project.
  • Building specifications.
  • Updated floor plans.
  • Construction schedule.
  • Payment schedule.

This documentation provides a clear understanding of exactly what is being purchased.

Have the Contract Reviewed by a Lawyer Before Signing

Having the purchase agreement reviewed by an independent property lawyer is highly recommended, particularly for international buyers.

A legal professional can verify aspects such as:

  • Bank guarantees.
  • Payment schedule.
  • Penalty clauses.
  • Cancellation conditions.
  • Included costs.
  • The developer's contractual obligations.

This small investment can prevent significant legal and financial issues later.
