Tax regimes

Qualifying is about the town. Whether it applies to you depends on criteria no map can check — where you were tax-resident before, and where your income comes from.

Buying in Serdiana is well below the Cagliari average of €1,604/m². Based on a single OMI micro-zone, so it describes the town as one market.
22.1 years of rent here equal the purchase price, close to the national median of 22.2 years.
A ratio between two OMI prices, not a return on investment. It leaves out purchase taxes, IMU, maintenance, financing and the months a place sits empty — all of which push the real figure up. Useful for the question it does answer: whether this town looks expensive to buy relative to what renting in it costs.
