Property prices
Buying in Castel Gandolfo is below the Roma average of €2,497/m². Averaged across 3 OMI micro-zones, which can differ substantially within the same town.
21.9 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.
A detached house here averages €2,175/m², against €2,008 for an apartment.
Compared street for street — houses and flats priced in the same neighbourhood — a house costs 8% more per square metre.
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 metre, but in 450 comuni it costs less — worth checking rather than assuming.
