Property prices
Buying in Saint-Denis is well below the Valle d'Aosta/Vallée d'Aoste average of €1,740/m². Based on a single OMI micro-zone, so it describes the town as one market.
36.6 years of rent here equal the purchase price — well 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.
