Among the eleven provinces of Lombardy, the Province of Sondrio stands out for a residential property market trend characterised by stability and limited fluctuations. The analysis of the official data for the three years 2023, 2024 and 2025 expressed in Normalised Number of Transactions (NTN) shows how the Valtellina area records the smallest percentage change in the whole region, remaining at substantially constant sales levels.

After a 2023 closed at 2,686.70 sales and a 2024 marked by a slight decline to 2,675.26 NTN (-0.43%), 2025 showed a modest recovery, reaching 2,709.43 NTN (+1.28% on the previous year). The overall balance for the three years thus shows a marginal increase of +0.85%, confirming Sondrio as the most stationary area in the Lombardy landscape.

Key data for the three years in the Province of Sondrio

Unlike the lowland provinces or the Milan metropolitan area, where double-digit accelerations were recorded, the Valtellina market responds to specific dynamics linked to the geography of the territory, the weight of the tourist component and a stable demographic structure.

Analysis of floor areas: the strong weight of small sizes

The structure of sales in the Province of Sondrio reveals a distinctive feature compared with the rest of Lombardy: a particularly high share of small homes (up to 50 sqm), driven by the presence of second homes and holiday properties in the mountain resorts.

Up to 50 sqm (Studios and small one-bedroom flats): They represent as much as 18.58% of the provincial total (503.28 NTN in 2025). This is almost double the regional average (10.21%), driven by transactions in ski and holiday resorts.
From 50 to 85 sqm (Large one-bedroom and compact two-bedroom flats): The most traded band with 1,003.54 sales (37.04% of the provincial market).
From 85 to 115 sqm (Two-bedroom and three-bedroom flats): They account for 603.58 NTN (22.28% of the total), the prevailing choice of the population living in the valley floors.
Over 115 sqm (Medium-large and large floor areas): Together, the 115–145 sqm and over 145 sqm bands cover 22.11% of sales (599.03 NTN in total).
