Castro-Urdiales Property Prices, Rents & Rental Yields

About Castro-Urdiales

Castro-Urdiales blends a sheltered Cantabrian coastline with a compact urban core, harbour views, and the everyday appeal of a seaside city that sits within reach of the wider Bilbao area. For apartments, that combination continues to shape how owners and investors read the market.

July 2026 brings the clearest signal: prices are still climbing, but rental gains are not keeping pace with the full investment cost. The average sale price holds at €285,000, yet it is still up 7.5% year over year, while the average m2 price stands at €3,170, also unchanged month over month and up 8.7% over the year. That points to a market where capital values have already re-rated, even before any new monthly movement appears.

The rental side tells a slightly different story. The average rent has moved to €1,300, rising 8.3% month over month and 8.3% year over year, which keeps income improving but not fast enough to erase the pressure created by higher purchase prices. Against that backdrop, the current yield of 5.69% looks serviceable rather than expansive. For apartment investors in Castro-Urdiales, July’s note is less about a sudden shift and more about a persistent tension: values remain firm, while income is improving, but from a base that has already been pushed higher.
