The Altomilanese and Magenta-Abbiatense: the Strength of the Outer Areas of the Hinterland (2023–2025)
Official data, Italian Revenue Agency
In the complex property geography of the province of Milan, the second and third metropolitan rings — represented emblematically by the hubs of the Altomilanese, the Magentino and the Abbiatense — are a fundamental residential lung for the whole Lombardy region. At an average distance of 20 to 35 kilometres from the city, these outer areas showed over 2023–2025 a significant ability to attract families and workers looking for large floor areas, green spaces and purchase prices more affordable than those of the first urban ring.
Through the official data of the Real Estate Market Observatory (OMI) of the Italian Revenue Agency, the descriptive analysis of sales (Normalised Number of Transactions - NTN) shows how the recovery of the property market in 2025 also reached the secondary and peripheral hubs of west and south-west Milan.
1. The Hubs of the West and West-South-West: Volumes and Three-Year Trends (2023–2025)
The geographic area stretching from Parabiago along the Sempione axis to Magenta and Abbiategrasso on the Naviglio Grande is one of the most established residential macro-routes in Lombardy. Over 2023–2025 the three main centres of the area recorded volumes close to 500 sales a year each:
- Magenta (OMI Code E801): After a dip in 2024 (342.56 NTN, a decline of -21.33%), Magenta recorded a lively restart in 2025, reaching 493.57 sales, a jump of +44.08% year on year and a balance of +13.34% on 2023 (435.46 NTN).
- Abbiategrasso (OMI Code A010): The historic reference point of the Abbiatense maintains marked structural stability with 489.17 NTN in 2025. The municipality absorbed the slight contraction of 2024 (461.16 NTN, +6.07% in 2025), closing the three years roughly even (-1.75% on 2023).
- Parabiago (OMI Code G324): Located along the Altomilanese railway axis, Parabiago shows uninterrupted growth over the three years: from 416.75 NTN in 2023 to 457.44 NTN in 2024 (+9.76%), reaching 485.87 NTN in 2025 (+6.21% on 2024), a cumulative increase of +16.59% over three years.
Among the second-tier centres of the same route:
- Corbetta (OMI Code C986): Stands at 308.67 NTN in 2025, showing a slight three-year adjustment (from 354.28 NTN in 2023).
- Bareggio (OMI Code A652): Reaches 270.12 NTN in 2025 (+24.87% on 2024 and +6.62% on the 253.35 NTN of 2023).
- Cerro Maggiore (OMI Code C537): Reaches 297.86 NTN in 2025 (+24.06% on 2024 and +8.86% on 2023).
- Arluno (OMI Code A413): Reaches 234.07 NTN in 2025 (+18.92% on 2024 and +16.04% on 2023).
2. Distribution by Floor Area: the Value of Large Spaces
Unlike the city of Milan — where sizes below 50 sqm make up almost a quarter of purchases (22.71%) — in the outer areas of the Altomilanese and Magentino-Abbiatense demand is almost entirely focused on family homes (two-bedroom and three-bedroom flats and detached homes).
Analysing the detail of 2025 sales:
- 50–85 sqm size (Large one-bedroom and compact two-bedroom flats): The queen band in the outer areas too, with shares between 35% and 46%. In Abbiategrasso it covers 46.28% of sales (226.41 NTN), in Bareggio 39.35% (106.29 NTN), in Magenta 36.56% (180.47 NTN) and in Parabiago 35.17% (170.88 NTN).
- 85–115 sqm size (Large two-bedroom and three-bedroom flats): Values well above the city average (20.08%). In Magenta it accounts for 34.24% (169.00 NTN), in Bareggio 34.18% (92.33 NTN), in Corbetta 32.78% (101.17 NTN) and in Parabiago 29.09% (141.34 NTN).
- Large floor areas over 115 sqm: In the municipalities of the Altomilanese and Magentino, homes above 115 sqm show shares between 20% and 27% of the local total (against 14.95% in Milan city). In Parabiago homes over 115 sqm make up 26.69% of the market (130.65 NTN, of which 70.64 NTN over 145 sqm), in Corbetta 26.73% (82.50 NTN) and in Magenta 22.92% (113.10 NTN).
- Micro-apartments (<50 sqm): Play a marginal role, with shares systematically below 10%: 9.06% in Parabiago (44.00 NTN), 7.36% in Abbiategrasso (36.00 NTN), 6.28% in Magenta (31.00 NTN) and 4.37% in Corbetta (13.50 NTN).
3. Comparative Pictures: Outer Areas vs Milan and the First Ring
The descriptive analysis highlights a complementary model of territorial development within the metropolitan province:
| Property indicator (Year 2025) | Milan city | Hinterland overall | Outer hubs (Magenta / Abbiategrasso / Parabiago) |
|---|---|---|---|
| Micro-size share (<50 sqm) | 22.71% | 8.57% | 6.28% – 9.06% |
| One/two-bedroom share (50–85 sqm) | 42.26% | 39.14% | 35.17% – 46.28% |
| Large two-bedroom share (85–115 sqm) | 20.08% | 30.02% | 26.76% – 34.24% |
| Large size share (>115 sqm) | 14.95% | 22.27% | 19.60% – 26.69% |

While the city concentrates investment demand and micro-housing for students and young workers, the Altomilanese and Magentino-Abbiatense absorb long-term settled demand, offering a more favourable floor area/price ratio and a structural supply of larger homes.

5. Summary and Outlook for the Outer Areas
The 2023–2025 analysis confirms that the strength of the outer areas of the Milan Hinterland lies in their functional specificity:
- Metropolitan balancing hubs: Municipalities such as Magenta, Abbiategrasso and Parabiago capture the flows leaving the city, ensuring a constant and resilient market absorption capacity.
- Prevalence of settled living: The clear prevalence of sizes between 50 and 115 sqm (over 70% of total sales), together with the resilience of floor areas above 115 sqm, testifies to the primary role of the Altomilanese and Magentino-Abbiatense as reference residential areas for the average Lombardy family.
- Railways as backbones: The centres with direct rail links to Milan (S5 line for Parabiago, S9 line for Abbiategrasso, Milan-Novara line for Magenta) show the fastest recovery performance in 2025.
