Castellón province boasts significant attractions, combining Mediterranean charm with a very dynamic real estate market. It features coastal cities like Peñíscola and Benicàssim, growing residential areas such as Vila-real, and more affordable prices can be found inland. For all these reasons, selling a property in this area can be an excellent opportunity for profit if done correctly, following a good strategy.
In this article, you will find a useful step-by-step guide that will explain how to sell your house in Castellón at the best price, avoiding common mistakes and taking full advantage of all current market trends.

According to data from early 2025, the average price per square meter for properties in Castellón is around 1,317 euros, but this can vary depending on the property's location.
For example, in the coastal area, where there are cities of high tourist value, the value of a property can exceed 2,000 euros per square meter.
In the capital (Castellón de la Plana), we can find stable demand with an average value of 1,378 euros per square meter.
And in inland areas like Vall d’Uixó or Segorbe, we can find much more affordable options, with properties where the value per square meter can even be below 800 euros.
Demand varies depending on the type of property and its intended use. For example, many national and international buyers looking for second homes are attracted to coastal areas. On the other hand, families and young professionals seeking a permanent residence prefer well-connected areas like Almassora and Vila-real. And investors often look for properties in emerging areas with good rental potential.
In the last year, we observed that prices rose by 7.8%, but during 2025, they have already reached a stable point. Furthermore, demand remains stronger in tourist areas, while inland areas offer opportunities for tighter budgets.
It is necessary to have the Property Deed, where it is registered in the Cadastre, along with the energy certificate, which has been mandatory since 2013, the latest IBI (Property Tax) receipt, and, if improvements or modifications have been made to the property, the Renovation Documentation.
Some tax obligations include IRPF (Personal Income Tax), where the capital gain obtained from the sale is declared, the municipal capital gains tax (Plusvalía municipal), which is the tax on the increase in land value, and, if the property is encumbered, any outstanding mortgage must be settled before or during the sale.
Additional expenses to consider include notary and registration fees, which typically range from 1% to 2% of the sale value, and, if applicable, the real estate agent's commission, which is usually 3% to 5% of the sale value.
It's essential to fix any necessary repairs on the property, even minor ones, as they can lead to long-term problems. This includes addressing leaks, cracks, or electrical issues.
It's important to pay close attention to the property's appearance, as its appeal often starts with what buyers see. It's advisable to use neutral paint, perform a deep clean, and ensure proper organization.
Implementing improvements and renovations, such as remodeling the kitchen or bathrooms, can increase the sale value, providing a good return on investment or real estate ROI.
Hiring an expert to take high-quality photos of the property from flattering angles can be a good investment, showcasing its full potential and attracting more buyers.
Having a good energy rating (A, B, or C) can significantly enhance the property's appeal.

If you lack experience in buying and selling properties, it can be a good idea to work with a real estate agency to speed up the sales process and help you avoid mistakes.
You need to research the price of other similar properties, also considering their exact location, as prices can vary by area. For this, you can access portals like idealista or Fotocasa. You can also take advantage of the valuation tools offered by some of these portals.
You need to set a price that aligns with the property's condition. If you've made recent renovations, you can justify a higher-than-average price.
It's important to remember that while a higher price might bring greater profit, if it's excessive, you could end up deterring buyers.

You should keep in mind that during a negotiation, you need to be flexible but firm on your minimum price. You can establish what is known as an earnest money contract (Contrato de arras), which is signed with a 10% deposit of the value to secure the sale. You should always have everything notarized, culminating in the notarization of the deed, for which you must verify that all documents are in order before signing.
If you set a price without prior research and comparison, you run the risk of setting it too low and incurring a loss, or setting it too high and inadvertently scaring off potential buyers.
If your property has any defects or damage, hiding them from buyers can lead to legal problems later on.
Failing to present your property with good photos can deter potential buyers.
If the property is neglected, it will have to be sold at a lower price.
It's always necessary to check the reputation of a real estate agency to ensure you hire a good and reliable service.
We can use online valuation tools, such as the one offered by idealista, compare current prices of other properties with similar characteristics in the same area, or hire a professional appraiser.
