Why live in Castellón?

Excellent quality of life

In Castellón, you'll find a pleasant Mediterranean climate, with over 300 days of sunshine a year and mild temperatures. Additionally, Castellón offers diverse natural landscapes, such as the pristine beaches of El Gurugú, the mountains of Desierto de las Palmas, and urban parks like Ribalta. In this area, you can live peacefully without sacrificing amenities, as it's a provincial capital with a small-town feel but equipped with all essential services like hospitals, universities, and an efficient transport system.

Competitive prices

In this area, you can still find good prices. According to data from the College of Registrars, the average price per square meter in Castellón ranges from 1500 to 2000 euros, which is 30% lower than in areas like Valencia or Alicante. Since demand has not yet driven up prices in Castellón, as it has in other tourist areas, it stands out as an excellent investment opportunity this year.

Strategic connections

It's worth noting that Castellón is just a 30-minute AVE train ride from Valencia, and its airport, only 20 km away, offers growing international flights.

Key factors to consider

1. ‍Realistic budget: You shouldn't just consider the apartment's price; you also need to add taxes (such as ITP 10% or VAT 10% if new), notary fees (0.5 to 1% of the sale price), and the appraisal, which can cost between 300 and 500 euros. For example, for an apartment priced at 150,000 euros, it's a good idea to budget for total expenses of at least 165,000 euros.
   ‍
2. Location based on your lifestyle: If you have a family-oriented lifestyle, areas like Parque Lledó, which have schools and green spaces, might be ideal for you. If you're a young professional or an investor, you're likely more interested in a property in the historic center or near Jaume I University, areas with high rental demand. And if you love the sea, in Grao de Castellón in El Serradal, you can find renovated apartments with sea views.
   
3. Property condition and community: You should check the energy efficiency certificate and avoid properties with G or F ratings, as these can make renovations more expensive. You should also request the minutes from the last community meeting to find out if there are any outstanding debts, and it's very important to consider the apartment's orientation. A south or southeast orientation can provide maximum natural light.

A new apartment requires less maintenance but also involves a 10% VAT. You can find them, for example, in Castellón Norte.

Second-hand

A second-hand apartment can have more character. They come with a 10% ITP, but it might be negotiable. Still, they might need renovations. It's recommended to look for buildings from the 90s or 2000s that have a good structure.

Penthouses and duplexes

These types of apartments are trending: you can find penthouses with terraces, which have appreciated by more than 15% in 5 years, in areas like Serra d’en Galceran.

‍

How to choose the ideal apartment?

• Visits: It is absolutely necessary to visit the apartment in person. It's recommended to go at least 3 times: in the morning, in the afternoon, and on weekends, to assess the noise levels and the surrounding environment. You should also check if the faucets and lights work properly, inspect for dampness, and inquire about electricity, gas, and water consumption.
• Smart negotiation: It's advisable to use tactics such as offering 10% less than the advertised price (as many sellers often anticipate this). If the deal is with a bank (in the case of a foreclosed property), up to a 15% discount may be accepted.

Key tips before buying or renting

Financing: mortgages in 2026

Both fixed-rate and variable-rate mortgages are available. In a high-interest rate environment, hybrid mortgages (fixed for more than 5 years plus a variable rate) are an interesting option. To compare, you can use specialized tools like HelpMyCash or iAhorro.

Aid and subsidies

It's a good idea to inquire about state payment assistance and subsidy programs that individuals can access. For example, the state housing plan offers up to 10,800 euros for people under 35, while in the Valencian Community, you can get a 50% bonus on property tax (IBI) for energy-efficient renovations.

Compare

It's recommended to compare at least 5 properties with similar characteristics in the same area. This can enable better negotiation, which currently can help secure 8% to 12% off the initial price, especially for homes that have been on the market for more than 3 months.
