How the Bank Valuation Works for Property in Castellón

When you find a property in Castellón and agree a price with the seller, that is only one side of the equation. The bank you approach for a Spanish mortgage will insist on its own valuation, known as the tasación, carried out by a valuation company registered with the Bank of Spain and instructed directly by the lender, not by you or the estate agent. Its job is to estimate what the property is actually worth using comparable sales, location, condition, size and legal status, independently of what buyer and seller have negotiated.

For buyers coming from the United Kingdom, this step often causes confusion, because in Spain the valuation is not a formality: it is the figure the bank uses to decide how much it is willing to lend. If the tasación comes in below the agreed price, the mortgage is calculated on the lower figure, and the buyer needs to cover the difference from savings. If it comes in above, the bank does not usually increase the loan beyond the purchase price itself.

Castellón province lies along the northern Costa del Azahar, offering a coastline with towns such as Peñíscola alongside inland mountainous areas. It tends to appeal to buyers seeking a quieter, less developed coastal environment compared to areas further south, including those interested in traditional Spanish towns and countryside.

The region is generally accessed via Valencia or Castellón airports, with more limited direct international flight options than larger hubs. Property types include coastal apartments, traditional village houses, and rural fincas, with activity increasing during the summer tourist season.

Before you commit to the numbers of a mortgage, it helps to know the place: dated figures on population, asking prices, transport links and climate in Castellón (province), each with its source. Together they give a grounded sense of Castellón (province) to weigh against your budget.

Castellón province, taken as a whole rather than just its capital, counted 627,620 registered residents on 1 January 2025 in the INE census. The number reflects the full territory, large and small municipalities alike, that makes up the province. The province of Castellón registers 118,810 residents of foreign nationality, about 19 out of every 100 people. That share is notable yet far from dominant, and it varies widely between towns within the province.

According to INE, only 1,423 British nationals were registered across the province of Castellón as of 1 January 2025. That low figure reflects the padrón's focus on year-round residents, excluding owners who use a property there only part-time. The table below lists the largest foreign nationalities registered in Castellón (province) on 1 January 2025, among those INE publishes for every municipality.

Beyond the main nationalities listed above, the INE also registers smaller groups, Germans, Italians, Dutch, Belgians or Scandinavians among them, across Castellón province. This breakdown reflects 1 January 2022, the last edition counting every nationality individually, a different year from the table above.

Our price bank includes 3,955 homes for sale throughout the province of Castellón, with a median of €1,740/m² and a median ticket of €179,000. Both are lower than the €3,135/m² median of the 130 towns we track across Spain, which puts the province on the more affordable side of the range. Among current adverts, the central half cluster between €1,230 and €2,370 per square metre; some properties are listed well below this band, others well above it.

In Castellón (province), the regional transfer tax rate of 9 % applied to the median asking price of €179,000 gives a tax bill of about €16,100, plus roughly €2,100 for notary, registry and gestoría charges. That puts the total near €18,300, money the mortgage will not cover. These are asking prices taken from adverts active on 2026-11-01, not confirmed sale prices. What a buyer actually pays is negotiated, and depends on the condition, exact location and orientation of each home.

Below is a comparison of the towns we follow in Castellón, covering inhabitants, foreign residents per 100 inhabitants and median asking prices per square metre across the province.

According to INE's experimental estimate from holiday-rental platform listings, Castellón (province) had 6,990 tourist dwellings in 05/2026, offering 37,362 bed places and close to 11 per 1,000 residents. The presence is moderate overall, but a regional licence remains necessary for tourist letting.

Castellón has a single commercial airport, Aeropuerto de Castellón (CDT); depending on where exactly in the province your property is located, an airport in a neighbouring province may actually sit closer to your door. These weather readings come from Castellón de la Plana, the capital of the province, so inland areas, higher ground or other islands within the same province can show noticeably different conditions. With January averaging 10.6 °C and overnight lows around 5.8 °C, against an August mean of 25.6 °C and highs near 30.3 °C, winters are mild rather than warm. Checking the heating in any home is a sensible step. With about 467 mm of rain a year on roughly 46 days, rain is neither scarce nor abundant here. On average, 2,755 hours of sunshine are recorded each year. These figures are the official climate normals (1981-2010) from AEMET, Spain's state weather agency, at its Castelló - Almassora station, about 4 km away; conditions at the exact property can differ slightly, especially inland or at altitude.

In the twelve months to 07/2026, 14,098 homes changed hands in the province of Castellón, INE figures show. Such activity tends to bring more reference prices and a larger selection for anyone searching. The figures above cover the whole province of Castellón, but they vary widely from town to town and from property to property.

The transfer tax on a resale home is set by each Spanish region. In Castellón the general rate is 9 %, and on top of it come notary, land registry and gestoría (roughly one more percent). On a new build you pay 10 % VAT plus stamp duty instead of the transfer tax. This money is not lent by the bank.

The valuation in Castellón is normally requested once the bank has pre-approved your file and before the mortgage offer is finalised. A qualified valuer visits the property, or in some cases works from documentation and photographs for straightforward cases, and produces a report considering the state of the building, its surface area, location within Castellón, recent comparable sales and any legal or planning issues affecting the title.

Because the valuer works for the bank, not for you, the report is designed to protect the lender's exposure rather than to reflect what you personally feel the property is worth. This is standard practice across Spanish banks and is not something specific to non-resident buyers, though as a non-resident you should expect the bank to request the same supporting documents on income and existing debts regardless of where the property sits.

The exact share of the price a Spanish bank will finance depends on the bank, your country and your personal profile, and non-residents are usually asked for a larger deposit than residents. When the tasación in Castellón is lower than the agreed price, that deposit requirement effectively grows, because the loan is anchored to the lower of the two figures. This is one of the reasons we recommend having some financial flexibility built into your budget before you commit to a purchase in Castellón.

It is also worth remembering that purchase costs sit on top of the price and the loan: transfer tax on resale homes (or VAT and stamp duty on new builds), notary, land registry, gestoría fees and the valuation itself all need to be funded separately, and none of these are covered by the mortgage.

Because you are buying from outside Spain, timing matters. Coordinating a valuer's visit to a property in Castellón while you are based in the United Kingdom can add a few days to the process, so it helps to have your file, including recent payslips, your last Self Assessment return, several months of bank statements and details of any existing loans, ready and translated in advance. A sworn translation is sometimes required, and some banks also ask for documents to be apostilled.

Currency is another practical point: since the United Kingdom uses the pound rather than the euro, the amount you need to transfer to Spain for the deposit shortfall, if the valuation comes in low, can shift with exchange rates between the moment you budget for it and the moment you actually pay. Building in a margin avoids last-minute surprises before completion at the notary.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
