Castellon province Property Prices, Rents & Rental Yields

About Castellon province

Castellon province stretches from Spain’s Mediterranean coast into a mountainous interior, bringing seaside municipalities and inland landscapes into the same regional picture. That geographic range matters when reading apartment figures for the province: an average describes the area as a whole, not every town or setting.

In October 2026, the clearest signal for apartments is that sale prices have risen faster than rents over the year. The average sale price is up 11.9% year on year, while the average rent is up 6.7%. That gap is the central tension for an investor: higher property values can increase the value of an existing holding, but they also raise the price of entry faster than rents have moved. The province-wide average sale price stands at €179,000.

The reported yield is 5.57%, best read as a regional reference rather than a return promised by any individual apartment. Set beside the different pace of sale and rent increases, it puts purchase-price discipline in focus. A province-wide yield cannot replace checking the asking price and plausible rental income for a specific property.

For investors, the practical takeaway is to assess capital growth and income separately. The yearly sale-price rise is notable, but slower rent growth leaves little basis for assuming that a higher purchase price will be matched by a proportionate increase in rental receipts. Province-wide averages offer context, not an apartment-level forecast.
