Property prices
Buying in Castello d'Argile is well below the Bologna average of €2,143/m². Averaged across 2 OMI micro-zones, which can differ substantially within the same town.
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.
Housing here in excellent condition costs 18% more than ordinary condition — €1,875/m² against €1,588.
That gap is what the market charges for a place you don’t have to work on. It is not what the work would cost you — OMI prices property, not builders.
A detached house here averages €1,560/m², against €1,588 for an apartment.
Compared street for street — houses and flats priced in the same neighbourhood — a house costs 8% more per square metre — the opposite of what the two averages above suggest, because OMI prices houses and flats in different parts of town.
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.
