Property prices

To buy

€738 /m²

To rent

€4.03 /m²/month

Buying in Castel Giorgio is well below the Terni average of €999/m². Averaged across 2 OMI micro-zones, which can differ substantially within the same town.

Buy or rent

15.3 years of rent here equal the purchase price — well below 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.

House or apartment

A detached house here averages €788/m², against €738 for an apartment.

Compared street for street — houses and flats priced in the same neighborhood — a house costs 7% more per square meter.

OMI prices “Ville e Villini” separately from the apartments every other figure on this page describes. Nationally a house costs about 14% more per square meter, but in 450 comuni it costs less — worth checking rather than assuming.
