Holiday Home or Permanent Move? Choosing the Right Property in Castellón

Many buyers from the United Kingdom start by browsing listings in Castellón before they've settled a more basic question: is this a place to live, or a place to escape to? The two answers point towards different streets, different sizes of property, and different legal steps. A flat that suits six weeks of summer holidays rarely suits a full-time household, and a family home bought for relocation can sit underused if plans change to occasional visits instead.

This isn't a minor detail to sort out later. It affects whether you need year-round services nearby, how much tax paperwork you'll face annually, and whether a tourist rental licence matters to you at all. Working through it early, with realistic timeframes, saves time and disappointment once you're comparing properties in Castellón.

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.

They help you judge, realistically, whether Castellón (province) suits what you have in mind, whether living there, holidaying or renting it out.

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.

For nationalities the census groups together rather than listing them individually, such as Germans, Italians, Dutch, Belgians or Scandinavians, we turn to the detailed INE register for Castellón province.

INE's experimental statistic, based on listings from the main holiday-rental platforms, counted 6,990 holiday-let homes in Castellón (province) in 05/2026 (37,362 bed places), about 11 per 1,000 residents. That is a moderate presence, and tourist letting still requires a regional licence.

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. The figures that follow reflect conditions in or around Castellón de la Plana, the provincial capital; elsewhere in the province, particularly inland, at altitude or on other islands, the climate can vary considerably. 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. Annual sunshine here runs to around 2,755 hours. 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.

Someone planning to relocate full-time to Castellón will usually prioritise proximity to schools, healthcare, public transport and everyday shops, even if that means a less scenic plot. Someone buying purely for holidays tends to prioritise the view, the beach or the golf course, and can tolerate a longer drive to the supermarket because they're rarely there outside peak season.

Neither choice is right or wrong, but conflating them leads to compromises nobody asked for: a holiday flat bought in a quiet residential street with no summer atmosphere, or a permanent family home chosen mainly for its pool and sea view, far from the services daily life requires.

A permanent move means registering as a resident, arranging a Spanish tax number (NIE) and, in most cases, a local bank account before completion. As the United Kingdom is no longer an EU member state, British citizens can stay in Spain for up to 90 days in any 180-day period without a visa; anyone planning to live there longer needs to apply for the appropriate visa or residence permit well in advance, since this takes time to arrange.

Day-to-day practicalities also weigh more heavily: internet reliability, public transport, proximity to a hospital, and whether the property suits ageing in place if that's part of the plan. A lawyer, while optional, is usual for foreign buyers precisely because these checks go beyond the property itself.

If Castellón will mostly see you for a few weeks a year, the property brief shifts towards low maintenance, strong rental potential if you plan to let it out, and proximity to the things that make a holiday feel like one. Community fees and municipal property tax (IBI) still apply every year regardless of how often you visit, so an empty property is never a cost-free one.

If you intend to let it to tourists while you're away, check the regional licence requirements early: many areas and buildings restrict or regulate short-term rentals, and this can rule out properties that otherwise look ideal on paper.

Whether Castellón becomes your home or your holiday retreat, the purchase itself carries transfer tax (ITP) set by the region for resale homes, or 10% VAT plus stamp duty for new builds, alongside notary, land registry and gestoría fees. Spain and the United Kingdom have a double taxation agreement in place, but a local adviser should confirm exactly how income or gains must be reported on both sides.

If you ever sell as a non-resident, the buyer withholds 3% of the price on account of your Spanish tax, and a municipal capital-gains tax (plusvalía) on the land value also applies. Since the United Kingdom uses pounds rather than euros, it's also worth factoring exchange-rate movements into any transfer of funds, both at purchase and later on.

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.
