What is off-plan purchasing?

Off-plan purchasing is a modality that consists of acquiring a home or commercial premises before it is built, making the decision based on the characteristics observed in the blueprints, models, and design promises. In this way, the buyer signs a contract with the developer and makes staggered payments during the construction period.

The main characteristics of off-plan purchasing are the possibility of obtaining a lower price, which is usually more economical than buying a completed home, and the possibility of customizing the construction by choosing finishes, materials, or the layout in early stages. The delivery period is generally between 1 to 3 years, depending on each project, and financing includes options such as some banks offering off-plan mortgages with special conditions.

Advantages 

More economical price

Real estate developers usually offer discounts of between 10% and 20% compared to the final sale price. For example, an apartment valued at 300,000 euros when completed can cost as little as 240,000 euros in its initial phase for off-plan purchase.

Customization possibility

For example, you can choose the flooring, sanitaryware, kitchen, and other types of finishes without the need to pay an additional cost (in most cases).

Appreciation before delivery

If the market in the sector rises, the buyer can benefit from immediate capital gains. For example, if the value increases by 5% annually, in just 2 years the home could be worth between 10% and 15% more.

Staggered payments

Payment is not made all at once, with the total amount upfront, but rather in installments linked to the progress of the work.

Tax benefits

In some autonomous communities, you can access reductions in ITP or VAT for the purchase of new construction.

Difference compared to buying completed properties

When buying a completed home, the price is the current market price, whereas with an off-plan purchase, you can buy for up to 20% less. In the initial stages of an off-plan purchase, you can access greater customization, but with a completed home, options are limited only to possible subsequent renovations.

On the other hand, the risk of an off-plan purchase is slightly higher, as it involves potential delays or non-compliance, whereas with a completed home, you buy what you see. For financing, it's necessary to find an off-plan mortgage (which is disbursed in stages) and not all banks offer them, while with a completed home, you can access a traditional mortgage.

Finally, a completed home can be purchased immediately, while with an off-plan purchase, the delivery period can be approximately 1 to 3 years.

When is it advisable to buy off-plan?

Buying off-plan is advisable if you're looking for initial savings, making it ideal for those who can wait and want to pay a little less. It's also a good option for investors if the area is expected to appreciate in value before delivery, and it's also perfect for those who desire personalization, allowing them to choose certain details from the outset without requiring costly renovations.

However, it's not a recommended option for those who need a home urgently, as delays are often common.

How to Invest: Step-by-Step 

Research the developer

You should check their history, whether they have delivered projects on time in the past or if they have complaints, as well as consult registries such as the Register of Developers at the College of Registrars.

Apply for financing (if necessary)

Some banks offer off-plan mortgages with phased disbursements. For example, BBVA and Caixabank have specific products for this type of purchase.

Sign a contract with guarantees
