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 Patrioti 1, Grosotto.

Grosotto, upper Valtellina between Tirano and Bormio

Grosotto lies in the Valtellina, upstream of Tirano, on the main road that climbs the Adda valley towards Bormio and Livigno. The village covers the valley floor and the lower slopes, with an old centre of stone houses and narrow lanes and meadows and woods above. For work and services, the reference points are Tirano and, further away, Sondrio.

Buyers need to factor in the climate: Grosotto is in climate zone F, with long, cold winters, so heating is a real cost. In houses in the old centre the thick walls help, but windows, roof insulation and the boiler make the difference. Newer homes are mostly on the edges of the village. For anyone working in tourism further up the valley the location is handy, and the main road gets busy in summer and on winter weekends.

Istat, the national statistics office, counts 1,630 residents in 2023, broadly stable since 2011 (+0.9%). The average age is 47.4, close to 46.8 for the province of Sondrio, and foreign residents make up 6.4%.

The province of Sondrio has 64 municipalities in seismic zone 3 and 13 in zone 4. Grosotto is in zone 3, with an expected ground acceleration of 0.083 g. For an old stone building, ask whether the roof and floors have been rebuilt and whether the walls are tied to the floors.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report works back to the land parcel. In an Alpine valley the slopes and the alluvial fans of side streams matter a great deal, and the report reads the official landslide and flood maps for the exact spot.
