Grognardo, in the Visone valley near Acqui Terme

Grognardo covers a stretch of the small valley of the Visone stream, in the hills near Acqui Terme. The town hall stands just over two hundred metres above sea level, but the land climbs towards higher, wooded ground, with scattered houses and small clusters of buildings along the country roads. Acqui is where people go for the big weekly shop, secondary schools, doctors and the train.

Buyers here usually want space and quiet, and most of what comes on the market is rural buildings and village houses that need work. The first thing to establish is where the property sits: down on the valley floor near the stream, or up on the slope, where the gradient, winter access and the state of retaining walls all matter. The report checks the official landslide and flood maps for the address and measures how far the nearest services are.

Figures from Istat, Italy's national statistics office, show a village that has shrunk: 231 residents in 2023 against 296 at the 2011 census, a fall of 22.0%. The estimated average age is 57.7, compared with 48.9 across the province of Alessandria, and over-65s make up 40.3%. Foreign residents account for 10.8%, and declared incomes are below the provincial average.

Grognardo is in seismic zone 3 on the national scale used by the Civil Protection Department, like 127 of the 187 municipalities in the province, with an expected ground acceleration of about 0.058 g in the built-up area. With an old farmhouse or village house, have a surveyor look at the roof and at how the walls and floors are tied together. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, so the report can trace the address back to its land parcel.
