Find out about the legal safeguards that protect you when buying off-plan in Spain, and why it is a safe and attractive investment option.
Buying off-plan in Spain

Buy off plan is one of the most popular ways of to buy a new-build property in Spain. Every year, thousands of domestic and international buyers reserve their future homes before construction is complete, attracted by benefits such as better prices, the option to customise certain finishes and access to promotions during the early stages of marketing.

However, it is common for doubts to arise regarding the security of this type of transaction. What happens to the sums paid during construction? What guarantees does the buyer have? What happens if the development is delayed?

The fact is that Spanish legislation provides a robust framework of protection for those who decide to buy off-plan. Furthermore, when the purchase is made with a a property developer with a proven track record, the process is even more secure and transparent.

In this context, companies such as Immosol Group, with decades of experience in developing residential developments on the Costa Blanca, we support our clients throughout the entire purchasing process, offering advice, transparency and all the guarantees required by current legislation.

The legal safeguards that protect buyers when purchasing a property off-plan

Spain has specific regulations designed to protect those who buy a property before it is completed. These are some of the main safeguards in place to protect the buyer.

1. Guarantee or security for the sums paid

One of the most important measures is the obligation to safeguard the deposits paid by the buyer during the construction phase.

The legislation stipulates that these sums must be protected by a bank guarantee or surety insurance. This means that, if the property is not built or is not handed over in accordance with the conditions laid down by law, the buyer may recover the money paid, as provided for in the applicable regulations.

This guarantee provides great peace of mind and is one of the cornerstones of legal certainty when buying off-plan.

2. Special account for development funds

Any sums paid by buyers during the construction phase must be deposited into specific accounts set aside exclusively for the development of the property.

This system makes it possible to monitor where the funds are allocated and ensures that the money provided is used to finance the construction of the homes.

This measure is designed to enhance transparency and protect buyers’ interests.

3. Contract of sale containing detailed information

Before finalising the purchase, the buyer receives a contract which must include clear and comprehensive information about the property and the terms of the sale.

Among other things, the document usually includes:

  • Description of the property.
  • Purchase price.
  • Payment schedule.
  • Estimated delivery date.
  • Specification of works.
  • Information on licences and authorisations.
  • Applicable legal guarantees.

Having this documentation enables the buyer to know exactly what they are purchasing and what commitments the developer has undertaken.

4. Planning permissions and authorisations

All property development projects must be carried out in accordance with current town planning regulations and must have the relevant administrative authorisations.

Before work begins, the developer must obtain the necessary planning permission to carry out the project. Furthermore, once construction is complete, the development must meet all the requirements for handover and occupation.

It is therefore essential to choose reputable developers with a proven track record in the development of new-build homes.

5. Guarantees following handover of the property

Buyer protection does not end with the handover of the keys.

Spanish legislation provides for various guarantees relating to potential construction defects that may arise after the property has been handed over. These guarantees cover different aspects of the construction depending on the nature of the issue and help to ensure the final quality of the property.

Furthermore, new-build developments today tend to incorporate materials, fittings and construction systems that are far superior to those used in homes built several decades ago.

Why buying off-plan in Spain remains a safe and attractive option

Legal guarantees are just one of the benefits offered by this method of purchase. There are numerous reasons why buying off-plan remains a particularly attractive option for those looking for a home in Spain.

As construction progresses and demand rises, prices may increase. For this reason, many buyers see buying off-plan as an opportunity to purchase a new home on more favourable terms.

Customisation options

Depending on the stage of construction, it is common to be able to choose finishes, materials or specific interior layouts, thereby creating a more personalised home right from the start.

More efficient and sustainable homes

New-build properties today meet the standards of energy efficiency increasingly demanding.

Better insulation, efficient heating and cooling systems, renewable energy and state-of-the-art materials enable us to enjoy homes that are more comfortable, sustainable and economical in terms of energy consumption.

There is usually a period of time between booking the property and receiving the keys, which allows you to plan all aspects of the purchase with greater peace of mind.

This leeway makes it easier to arrange financing, sell a previous home or plan a move, thereby reducing the stress associated with an immediate purchase.
