El Grau de Castelló Property Prices, Rents & Rental Yields

About El Grau de Castelló

El Grau de Castelló combines a coastal setting with the working-port identity of Castellon’s maritime district, giving it a distinctly local character. Apartments here sit close to the seafront and everyday urban services, making the area relevant to both lifestyle and investment-led searches.

September 2026 brings the clearest signal: rents are easing faster than values, while the broader pricing trend still points upward. The average apartment sale price stands at €170,000, down 3.1% month over month, and the average rent is €900, down 5.3% over the same period. Yet the average price per square metre remains at €1,750, up 0.4% month on month and 21.1% higher than a year ago.

That combination creates a sharper tension for investors. Gross yield is currently 7.66%, which helps explain why the market can still look attractive even as monthly rent softens. At the same time, the year-over-year rise in both sale values and rent suggests the underlying pricing environment remains firm. For buyers evaluating apartments in El Grau de Castelló, September reads as a month of short-term adjustment inside a longer upward trend.
