Published on May 2, 2026 and written by Cyril Jarnias

Portugal is attracting more and more foreign real estate investors, drawn by its exceptional quality of life and still affordable prices. Among investment strategies, renovating an older property proves particularly interesting. Indeed, renovating a property in Portugal can significantly increase its value, while allowing you to create a unique and personalized living space. Whether you have a primary residence, secondary home, or rental project, discover how to successfully carry out your renovation and maximize your investment.

A Booming Portuguese Real Estate Market

Before embarking on a renovation project, it is essential to understand the dynamics of the Portuguese real estate market. In recent years, the country has experienced a true real estate boom, particularly in major cities like Lisbon and Porto.

Prices have seen a significant increase but remain attractive compared to other European destinations. According to recent data from Idealista, one of the leading real estate portals in Portugal, the average price per square meter in Lisbon is around €5,000, while it hovers around €3,500 in Porto. These figures naturally vary depending on the neighborhood and property type.

Despite a slight slowdown observed in 2024, due notably to stricter conditions for granting golden visas, the Portuguese market remains dynamic. Experts predict a stabilization of prices in 2025, with moderate increases of 1 to 3% in the most sought-after areas.

In this context, renovating an older property appears to be a particularly relevant strategy. It allows you to acquire a property at a more affordable price and then significantly increase its value through targeted work.

Key Steps for a Successful Renovation in Portugal

Renovating a property in Portugal requires a methodical approach and a good understanding of local specifics. Here are the main steps to follow to successfully carry out your project:

1. Thorough Property Assessment

Before any purchase, it is crucial to have a complete diagnostic of the property carried out by qualified professionals. This step will help identify priority work and estimate its cost. Pay particular attention to the condition of the structure, roof, and electrical and plumbing installations.

2. Obtaining Necessary Permits

In Portugal, most renovation work requires obtaining a permit from the town hall (Câmara Municipal). Processing times can vary from a few weeks to several months depending on the project’s scope and the municipality involved. It is highly recommended to hire a local architect to assist you with these administrative procedures.

3. Selecting Contractors and Companies

The choice of professionals who will carry out the work is crucial to the success of your project. Prioritize local companies with solid experience in renovating older properties. Do not hesitate to ask for references and visit ongoing construction sites to get an idea of the quality of their work.

4. Planning and Monitoring the Construction Site

Once work begins, regular monitoring is essential to ensure deadlines are met and quality is maintained. If you cannot be present on site, consider hiring a project manager or local site supervisor.

5. Finishing and Decorating

The final step is to personalize your renovated property. This is an opportunity to highlight elements of traditional Portuguese architecture while adding a touch of modernity. The choice of materials and colors is crucial for creating an authentic and warm atmosphere.

Financing Your Project: Options and Strategies

Financing is a crucial aspect of any renovation project. In Portugal, several options are available to foreign investors:

Portuguese Mortgage Loans

Portuguese banks offer mortgage loans to non-residents, including for renovation projects. Interest rates are generally competitive, ranging between 3% and 5% depending on the profile. However, lending conditions may be stricter for foreigners, including:

• A minimum down payment of 30% to 40% of the total amount
• A maximum repayment term of 30 years
• The requirement to take out life insurance with a Portuguese insurer

Financing from Your Home Country

Depending on your situation, it may be advantageous to take out a loan in your country of residence. This option often allows for more favorable conditions, particularly in terms of interest rates and repayment terms. However, be sure to account for currency exchange and international transfer fees.

Self-Financing

If you have the necessary funds, self-financing remains the simplest and most economical solution. It allows you to avoid bank fees and gain flexibility in managing your project.

Regardless of the option chosen, it is crucial to establish a detailed budget that accounts for all costs related to the renovation:

• Property purchase
• Notary fees and taxes (approximately 7% to 8% of the purchase price)
• Cost of work (on average between €500 and €1,500 per m² depending on the scope of the renovation)
• Professional fees (architect, project manager, etc.)
• Contingencies (plan for a margin of 10% to 15% of the total budget)

Materials and Techniques: Between Tradition and Modernity

The choice of materials is a key element in the success of a renovation in Portugal. It is about finding the right balance between respecting traditional architecture and integrating modern solutions for comfort and energy efficiency.

Traditional Materials to Prioritize

Portugal has a rich architectural heritage, with emblematic materials that should be preserved or reintroduced during a renovation:

• Limestone, very common in Portuguese architecture, especially for door and window frames
• Azulejos, the colorful ceramic tiles that adorn many facades and interiors
• Pine or oak wood, used for frames, floors, and joinery
• Lime, traditionally used for interior and exterior plasters

Modern Solutions for Energy Efficiency

Alongside the use of traditional materials, it is important to integrate modern solutions to improve the building’s energy performance:

• Enhanced thermal insulation (roof, walls, floors)
• Double or triple glazing for windows
• Energy-efficient heating and cooling systems (heat pumps, solar panels)
• Mechanical ventilation system (MVHR) for better indoor air quality

The goal is to create a comfortable and energy-efficient home while preserving the charm and authenticity of the old building.

Focus on Specific Renovation Techniques

Certain renovation techniques are particularly well-suited to the Portuguese context:

• Restoration of exposed stone facades, very common in historic centers
• Refurbishment of roofs with canal tiles, typical of Mediterranean architecture
• Renovation of terracotta or hydraulic mosaic floors, characteristic of older homes
• Integration of rainwater harvesting systems, a traditional practice brought up to date

Maximizing the Value of Your Renovated Property: Keys to Success

Once your property is renovated, several options are available to make the most of it:

Resale

If your goal is to realize a capital gain in the short or medium term, resale can be an interesting option. The Portuguese real estate market remains dynamic, particularly for quality properties in sought-after areas. A well-executed renovation can allow you to achieve a significant margin, potentially up to 30% or 40% of your initial investment.

Short-Term Rentals

Portugal is a top tourist destination, offering excellent opportunities for short-term rentals. A tastefully renovated property, combining old-world charm with modern comfort, can generate attractive rental income, especially in major cities or coastal areas. However, be sure to research local regulations regarding short-term rentals, which are becoming stricter in some areas.

Long-Term Rentals

For a more stable long-term investment, year-round rental is an option to consider. The Portuguese rental market is expanding rapidly, driven by growing demand from expatriates and local young professionals. A renovated and well-located property can provide you with regular income while benefiting from potential capital appreciation.

Personal Use

Finally, if your project is to use the property for yourself, whether as a primary or secondary residence, a successful renovation will allow you to enjoy an exceptional living environment, combining old-world charm with modern comfort. It is also an opportunity to create a unique space, perfectly tailored to your tastes and lifestyle.

Renovating a property in Portugal represents a unique opportunity to create an exceptional property while making a potentially very profitable investment. With a methodical approach, a well-managed budget, and the right choice of local partners, your renovation project has every chance of turning into a true real estate success story.

Remember that every project is unique and deserves special attention. Do not hesitate to surround yourself with experienced professionals to guide you throughout your real estate adventure in Portugal.
