Castelldefels Property Prices, Rents & Rental Yields

About Castelldefels

Castelldefels combines a Mediterranean coastal setting with easy access to the Barcelona metro area, making it a distinctive city for apartment investment. Its appeal lies in the blend of beachside living, urban connectivity, and a housing market shaped by both local use and broader provincial dynamics.

July 2026 brings a clear market signal: apartment pricing moved higher again, but the income picture stayed steady. The average sale price reached €375,000, while the average price per square metre rose to €4,570, both up 7.1% month over month. That monthly climb suggests renewed pricing momentum even as the average rent held at €1,800.

The tension for investors is straightforward. Gross yield stands at 6.67%, which looks solid in isolation, yet it sits alongside a market where capital values have not fully recovered year over year, with the average sale price down 6.5% and the average price per square metre down 0.8%. In other words, Castelldefels is showing firmer pricing month to month, but not a simple straight-line recovery across the longer comparison.

For apartment investors, that combination matters. July’s figures point to a market where sale values are moving faster than rents, so returns may depend more on entry price discipline than on immediate rental growth. The latest data does not suggest a change in rent momentum, but it does show that ownership costs are being repriced upward in the short term.
