Castelsardo Property Prices, Rents & Rental Yields

About Castelsardo

Castelsardo, perched above the Gulf of Asinara in northern Sardinia, blends a historic hilltop core with coastal views and a compact urban fabric. For apartment investors, that mix keeps the town firmly tied to both local life and seasonal interest.

August 2026 brings the clearest signal in Castelsardo’s apartment market: values are still moving higher, while the income side has not kept pace. The average sale price now stands at €139,000, after rising 8.6% year on year, and the average square-meter price has climbed to €2,320, up 15.8% over the same period. By contrast, the average rent price is holding at €1,000, unchanged month on month despite a 33.3% increase year on year.

That gap matters because it leaves investors balancing appreciation against a yield that remains measurable but not immune to pressure. The current gross yield is 8.41%, which suggests the market still supports income, yet the faster rise in purchase pricing than in rents points to tighter economics than a year ago. With no month-over-month movement in sale, rent, or per-square-meter pricing, August reads as a pause in monthly momentum rather than a reversal. For apartment buyers, Castelsardo currently looks less like a discount story and more like a market where higher asset values are testing rental growth.
