Castellon province Property Prices, Rents & Rental Yields

About Castellon province

Castellon province combines Mediterranean coastline, inland mountain scenery, and a long-established apartment market shaped by both city living and holiday use. Its varied geography gives the area a broad appeal within Spain’s eastern corridor.

July 2026 points to a market where values are still advancing. The average apartment sale price has reached €175,000, while the average price per square metre stands at €1,840, both up 0.6% on the month and 16.7% higher than a year ago. That pace suggests the market is continuing to reprice rather than simply pause after earlier gains.

Against that backdrop, rental growth looks steadier. The average rent is €850, unchanged from June but 9.0% above July 2025. That contrast matters for investors because the yield sits at 6.1%, indicating that income is keeping pace, but not fully offsetting the stronger rise in purchase prices. In other words, Castellon province is entering the second half of 2026 with apartment pricing still firm and returns needing careful underwriting rather than assuming last year’s entry points still apply.
