The real estate market in Castellón de la Plana is establishing itself as one of the cornerstones of the local economy. Its potential for expansion and a growing market make it a hot spot for those looking to buy, rent, or renovate properties.
Today, Castellón is undergoing a phase of expansion and transformation that promises to offer attractive returns for real estate investors. Below, we give you three reasons why investing in this area is an interesting idea, to say the least.
One of the key factors driving the property market in Castellón is its economic development. In recent years, the city has seen a notable increase in employment and the creation of new businesses. While the port remains its mainstay, the city has experienced a boom in sectors such as tourism, technology, and services.
This economic growth translates into greater demand for both owner-occupied and rental housing, creating a favorable environment for real estate investors.
Over the last decade, Castellón's infrastructure has improved considerably, boosting its interconnectivity both nationally and internationally. The city is perfectly connected to other major cities such as Valencia and Alicante, thanks to its excellent transport network and international airport.
In addition, urban development projects are underway that promise to increase the value of various areas of the city. These changes create a perfect symbiosis between tourist dynamism and a professional community that chooses Castellón as their place of residence.

Another solid argument for investing in Castellón de la Plana is the existence of urbanization and revitalization projects in peripheral areas. Thanks to these projects, areas that were previously undervalued are now becoming highly sought-after neighborhoods. Projects such as Ciudad del Mar (coastal regeneration) and the expansion of green areas are making it a magnet for investors.
Real estate in Castellón is undergoing a period of sustained expansion, with a gradual increase in demand for both purchases and rentals. Property values have shown steady growth in recent years, ensuring stable appreciation of real estate.
For now, the real estate supply in Castellón is in balance with demand. However, some segments of the market, such as new-build properties, are seeing significant interest thanks to their higher quality and modernity.
On the other hand, the single-family home market remains stable, although demand is more focused on the outskirts of the city. In particular, interest in two- and three-bedroom properties has grown, as these are the most sought-after for both purchase and rent.
Since 2020, the price per square meter in the province has experienced a gradual but steady increase. According to official sources, the average value per square meter of residential property in Castellón in 2024 rose by 5% compared to 2023.
Compared to other cities in the Valencian Community, Castellón remains a relatively affordable option for investors. This makes it an attractive alternative to more expensive options such as Valencia or Alicante, although prices are expected to continue rising in the coming years.

Despite being a quieter area, Gurugú Beach is experiencing an increase in real estate investment, especially in tourist accommodation. Interest in beachfront properties remains high and is expected to continue to rise.
If you are looking to invest in property for the long term, areas undergoing development or revaluation can be an excellent option. These areas have great potential for appreciation in the coming years, making them an attractive option for investors with a long-term vision.
