For example: Via dei Pini 1, Valentano.
Valentano, Tuscia above Lake Bolsena
On the western side of Lake Bolsena, at over 500 metres, Valentano looks down on the water. It is a village in the Tuscia, the area around Viterbo, built around the Rocca Farnese castle, which now houses the local museum of prehistory, and surrounded by fields, olive groves and pasture on volcanic soil. Viterbo is about three quarters of an hour by car, the lake a few minutes.
The market is typical of Tuscia villages: stone houses in the old centre, often on several levels and in need of restoration, and newer homes with gardens on the edge of the village. In the countryside there are farmhouses and agricultural land; for these, access roads, water and distance to services matter, and the report measures that from the address.
There are 2,789 residents (2023), down 3.7% since 2011. The average age is 49.1 against 47.5 for the province of Viterbo, people over 65 make up 29.0% and households have 1.98 members on average, so many people live alone or as a couple. Foreign residents make up 7.4%, and declared incomes are a little below the provincial average.
Valentano is in seismic zone 2, like 39 other municipalities in the province, with an expected ground acceleration of 0.140 g. In the tufa and stone houses of the centre, ask whether roofs and floors have been worked on, and under which permits.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report gets down to the parcel. The climate is zone E in the Italian classification: the altitude makes winters colder than you might expect in Lazio.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.140 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
For anyone buying in Valentano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
