Official data, Italian Revenue Agency
The analysis of the official data on residential sales (Normalised Number of Transactions - NTN) highlights a central and increasingly important role for the Milan Hinterland (comprising the municipalities of the province other than the provincial capital). In 2025 the metropolitan area outside the city passed the symbolic threshold of 45,000 sales, reaching 45,422.82 NTN.
This result marks an expansion of +7.82% on 2024 (42,127.97 NTN) and an overall increase of +8.08% on 2023 (42,028.64 NTN). The Milan hinterland thus confirms its role as the main lung of the provincial residential market, absorbing 64.34% of all transactions in the province of Milan.
Evolution of sales in the Hinterland (2023 - 2025)
While in 2024 the city of Milan had recorded a temporary contraction of -3.40% due to the tightening of mortgage rates, the Milan hinterland showed extraordinary resilience, remaining positive in 2024 too (+0.24%) and accelerating strongly in 2025.

Analysis of territorial dynamics in the Hinterland
The quantitative data reveal some clear structural trends in the market of the metropolitan area:
- Dominance of family floor areas (>85 sqm): More than half of the purchases made in the Hinterland (52.29%, equal to 23,753.14 NTN) concern homes above 85 sqm, compared with only 35.03% recorded in the municipality of Milan.
- Limited micro-sizes: Small apartments up to 50 sqm account for only 8.57% of sales in the Hinterland, against 22.71% in the city, confirming that the outer area mainly meets stable, primary housing needs.
- Decentralisation and spread: The large hubs of the first and second ring (including Sesto San Giovanni, Legnano, Cologno Monzese, Rho and the municipalities of North and South Milan) concentrate an impressive volume of sales, ensuring a polycentric network spread across the entire provincial territory.
Summary and reading notes
The Milan Hinterland is confirmed as the quantitative hub of residential growth in Lombardy over 2023-2025. With 45,422.82 sales in 2025 and a share of 64.34% of the provincial total, the outer area records the prevailing share of transactions by families looking for large sizes and detached homes or homes above 85 sqm.
