Tax regimes
Sant'Antioco qualifies for the 7% pensioner regime. Comfortably below the 30,000-resident ceiling.
Qualifying is about the town. Whether it applies to you depends on criteria no map can check — where you were tax-resident before, and where your income comes from.
How the 7% pensioner regime works, and every qualifying comune →Property prices
Buying in Sant'Antioco is well above the Sulcis Iglesiente average of €955/m². Averaged across 2 OMI micro-zones, which can differ substantially within the same town.
23.7 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 €1,800/m², against €1,313 for an apartment.
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.
Seismic zone
Sant'Antioco is in seismic zone 4. Of the four zones, zone 1 is the highest hazard and zone 4 the lowest. The Department of Civil Protection describes zone 4 as the lowest-hazard zone, where a strong earthquake is very unlikely.
This is the legal classification the Region gave the comune, used for planning and for control of building works. It is not a forecast, and it says nothing about the building you are looking at: since the 2018 building code the design load of a new building comes from site-specific hazard, not from the zone. Have any specific property checked by a qualified engineer.
Not to be confused with the “seismic” routes of the 7% pensioner regime. Those turn on whether the comune was in the 2009 L’Aquila or 2016–17 central-Italy earthquake areas, not on its zone, and being in zone 1 does not make anyone eligible for that regime, or for any tax treatment.
