When investing in real estate in Spain, it is essential to determine whether you prefer to buy a new property—either off-plan or already completed—or a resale property, whether recently built or in need of renovation. Each option comes with specific advantages and disadvantages, both in terms of taxation and in relation to profitability and property value. Understanding these differences is crucial to building a profitable and secure investment strategy.

 

1. Investing in a New Property

 

There are two scenarios: buying off-plan, before or during construction, and buying a completed property that is already built and ready for use.

 

 

Buying Off-Plan

 

Advantages

Buying off-plan offers several benefits. First, the purchase price is often lower than the final market value, allowing you to generate capital appreciation upon delivery. Payments are made in instalments based on construction progress, which facilitates cash-flow management. Additionally, you can personalize the property by choosing materials, finishes, interior layout, and certain smart-home features. Finally, modern construction standards guarantee low energy consumption and limited maintenance costs.

Disadvantages

However, buying off-plan also comes with constraints. There is a waiting period before the property can be occupied or rented, which limits initial cash-flow. The investor relies on the developer’s reliability, and delays or modifications may occur.

 

 

Buying a Newly Completed Property

 

Advantages

Purchasing a completed new property provides immediate availability. The property can be rented or occupied as soon as it is acquired. You can assess the actual build quality, location, and finishes. As with off-plan properties, these homes meet modern standards and offer low energy consumption. Their appeal on the premium market also facilitates resale and ensures predictable capital appreciation.

Disadvantages

The purchase price is generally higher than for off-plan properties. Customization is limited since the property is already delivered. Initial cash-flow is positive but proportional to the higher cost of the asset.

 

 

Taxation

  • VAT (IVA): 10%

  • Stamp Duty (AJD): 0.5% to 1.5% depending on the region – Costa Blanca: 1.5%

Costa Blanca example – new property at €1,000,000 → Total tax: €115,000

 

 

2. Investing in a Resale Property (recent or to renovate)

 

 

Advantages

Resale properties can generate rental income immediately and can be occupied or sold as soon as they are acquired. They offer full visibility of the asset, making it possible to evaluate build quality, surroundings, and natural light. Investors can negotiate the price and create additional value through renovation work.

Disadvantages

These properties may require renovation, involving additional costs and more complex management. Energy performance is often lower than that of new buildings. Cash-flow is immediate but depends on the property’s condition and the renovations carried out.

 

 

Taxation

 

The ITP (Impuesto sobre Transmisiones Patrimoniales) varies between 6% and 10% in Spain depending on the region.
For the Valencian Community / Costa Blanca: 10%

Costa Blanca example – property at €1,000,000 → Total tax: €100,000

 

 

Our Recommendations Based on Your Investment Objective

 

 

The choice between off-plan, newly completed, or resale depends on your wealth strategy, investment horizon, and risk tolerance.

  • Off-plan: ideal for generating secure capital appreciation and benefiting from full customization.

  • Newly completed: allows immediate cash-flow and guarantees modern construction standards, but at a higher cost.

  • Resale: offers quick cash-flow and the possibility of increasing value through renovations.

 

Location and Resale Potential

 

In Spain—and especially on the Northern Costa Blanca—new properties offering a modern and high-quality living environment attract an international clientele and ensure strong long-term investment security. Renovated resale properties can also sell very well if the location is good and the renovation work is high quality and aligned with market expectations.
