Property prices
Buying in Mazzo di Valtellina is well below the Sondrio average of €1,483/m². Averaged across 3 OMI micro-zones, which can differ substantially within the same town.
26.1 years of rent here equal the purchase price — above 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 27% more than ordinary condition — €1,141/m² against €900.
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 €950/m², against €900 for an apartment.
Compared street for street — houses and flats priced in the same neighbourhood — a house costs 6% 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.
