The province of Castellón has many attractions, combining Mediterranean charm with a very dynamic real estate market. It features coastal towns such as Peñíscola and Benicàssim, as well as growing residential areas like Villa-Real, and more affordable prices can be found inland. For all these reasons, selling a home in this area can be an excellent opportunity for profit if done correctly, following a sound strategy.
In this article, you'll find a helpful step-by-step guide that explains how to sell your home in Castellón for the best price, avoiding common mistakes and taking full advantage of current market trends.

According to data from early 2025, the average price per square meter for properties in Castellón is approximately 1,317 euros, but this can vary depending on the area where the property is located.
For example, in the coastal area, where there are cities with high tourist appeal, the value of a property can exceed 2,000 euros per square meter.
In the capital (Castellón de la Plana), we see stable demand with an average price of 1,378 euros per square meter.
And in inland areas such as Vall d’Uixó or Sergobe, we can find much more affordable options, with properties where the price per square meter can even be below 800 euros.
Demand varies depending on the type of property and its intended use. For example, many domestic and international buyers looking for second homes are drawn to coastal areas. On the other hand, families and young professionals seeking a permanent home tend to prefer well-connected areas such as Almassora and Vila-Real. And investors typically look for properties in up-and-coming areas with strong rental potential.
Over the past year, we have seen prices rise by 7.8%, but by 2025, they have already stabilized. Furthermore, demand remains stronger in tourist areas, while inland areas offer opportunities for those on a tighter budget.
You must provide the title deed (if the property is registered in the Land Registry), the energy performance certificate (which has been mandatory since 2013), the most recent property tax (IBI) bill, and, if any improvements or modifications have been made to the property, the renovation documentation.
Some of the tax obligations include income tax, under which the capital gain from the sale must be reported; municipal capital gains tax, which is the tax on the increase in land value; and, if the property is mortgaged, the outstanding mortgage must be paid off before or during the sale.
Some additional costs to keep in mind include notary and registration fees, which typically amount to between 1% and 2% of the sale price, and, if applicable, the real estate agent’s commission, which amounts to between 3% and 5% of the sale price.
It is important to address any necessary repairs on the property, including minor ones that could lead to problems down the road. This includes fixing leaks, cracks, or electrical issues.
We should pay close attention to the property’s appearance, as first impressions are key; for this reason, it’s a good idea to use a neutral paint color, give the place a thorough cleaning, and make sure everything is tidy.
Making improvements and renovations, such as remodeling the kitchen or bathrooms, can increase the property's resale value, providing a good return on investment ( ROI).
It can be a good investment to hire a professional to take high-quality photos of the property from flattering angles that showcase its full potential, thereby attracting more buyers.
Having a good energy rating (A, B, or C) can greatly enhance a property's appeal.

If you don't have experience buying and selling properties, it might be a good idea to work with a real estate agent who can speed up the selling process and help you avoid mistakes.
It’s important to research the prices of other similar properties, taking their exact location into account as well, since prices can vary by area. To do this, you can visit websites like Idealista or Fotocasa. You can also take advantage of the valuation tools that some of these websites offer.
It is necessary to set a price that reflects the condition of the home. If we have recently made renovations, we can justify a price higher than the average.
We must remember that, while a higher price may yield greater profits, if it is too high, we may end up driving buyers away.

Keep in mind that during negotiations, you should be flexible but firm on your minimum price. You’ll need to draw up what’s known as a deposit agreement, which involves paying a deposit of 10% of the property’s value to secure the sale. And 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 we set a price without first doing some research and comparing prices, we run the risk of setting a price that’s too low and selling at a loss, or setting a price that’s too high and unintentionally scaring off potential buyers.
If our property has any defects or damage, hiding them from buyers could lead to legal problems later on.
Failing to showcase our property with good photos can scare off potential buyers.
If the property is in poor condition, it will have to be sold at a lower price.
It’s always important to check a real estate agency’s reputation to ensure you’re hiring a good, reliable service.
We can use online valuation tools, such as the one offered by Idealista, compare current prices of other properties with similar features in the same area, or hire a professional appraiser.
According to statistics, 32% of homes can be sold within a period ranging from 3 months to a year. Meanwhile, homes with attractive prices and locations—approximately 22% of properties—can be sold in less than a month.
Yes, it is possible, provided that the inheritance tax has been paid before the sale.
Bathroom and kitchen renovations, as well as improvements in insulation and energy efficiency—such as installing double-pane windows—are appealing to most buyers.
During the warmer months of spring and summer, demand is usually higher, especially in coastal areas.
