The OMI values of the Italian Revenue Agency, area by area: a yardstick for comparison, not an appraisal of a single property.
In Zagarolo the value of a home ranges from €750 to €1,700/m² in the OMI zones (zone OMI) for the first half of 2026. To get a sense of the town, one figure is enough: half of the zones have a minimum below €900/m², and half have one above.
The town has four zones with values. The most expensive is D1, Colle Barco-Palombara-Colle Gentile-Colle Villa, a peripheral area, at €1,150-€1,700/m². If you are looking at an auction in zone E6, Valle Martella, the sale reference is between €750 and €1,100/m².
In 2025, the 3+2 agreed-rent lease (contratto 3+2) stood at about €6.4/m² per month (109 contracts), the 4+4 open-market lease (contratto 4+4) at about €5.9 (56 contracts), and the transitional lease at about €4.0 (19). If you are evaluating a rent, compare it with these figures, taking the zone into account.
According to the MEF, declared incomes for 2024 show an average income of €22,142 across 11,638 taxpayers. Property sales, on the other hand, concern the rest of the Province of Rome, excluding the capital: over the last four quarters there were 20,092, and in the 2nd quarter of 2026 there were 5,401, with a mortgage used in 51% of cases.
Before forming an opinion, compare the auction price with the zone in which the property is located.

The OMI values of the Italian Revenue Agency are ranges for an area, a property type and a period. They do not value a single flat and do not replace a professional appraisal. A fair comparison also needs condition, floor, exposure and documentation.
On the auction pages, the “below the area value” discount shows how far the minimum offer per square metre is below the minimum of the area range. A lower value does not equal an expected gain.
