The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.

For example: Via Maniva 1, Collio.

Collio, the head of the Val Trompia below the Maniva pass

At the top of the Val Trompia, where the road climbs to the Maniva pass, the municipality of Collio takes in its main village and several hamlets spread across woods, pastures and steep slopes. This is the highest part of the Mella valley, in the province of Brescia: there is skiing in winter, walkers and holidaymakers come in summer, and many residents commute down to the middle valley and Brescia for work.

The property market reflects this double life. Next to residents' homes there are flats and small villas used as second homes, plus mountain huts and rural buildings higher up. Before buying, ask about running costs, the state of the roof and the heating system, because the climate zone is F, the coldest, and the cold months are long. Roads, snow and sunlight vary a lot between hamlets; the report reads the official landslide maps and stream flood maps for the address.

According to Istat, Italy's national statistics office, 1,994 people lived here at the end of 2023, down 10.5% on 2011. The average age is 48.6, against 45.4 for the province, and 27.1% of residents are over 65. Foreign residents make up 5.8%. Declared incomes are well below the Brescia average.

Collio is in seismic zone 3, like 152 other municipalities in the province, with an expected ground acceleration in the built-up area of 0.122 g. For a mountain hut or stone house, the useful checks are the roof, floors and how the walls are tied together.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report goes from the address to the building's land parcel.
