Mainz as an investment location for real estate
227,277 registered persons (total) - 224,030 main residences: stable demand base in the state capital
As at 31.12.2024, Mainz had a total of 227,277 registered residents (main and secondary residences), of which 224,030 were main residents; the proportion of foreigners is 46,716, which underlines the urban, international demand base of the state capital. The official city website shows the size and age structure in detail (including 43,258 people aged 25-34, 23,920 aged 18-24), which indicates a broad target group base ranging from students and young professionals to families. External series confirm Mainz as the largest city in Rhineland-Palatinate in the 2024 corridor and place the number of inhabitants in the same range, with minor methodological differences. Neighborhood data show dense, high-demand inner-city locations (e.g. Altstadt with 17,710 inhabitants per 2,414km²; 7,336 inhabitants/km²), which support core profiles in central and public transport-related areas.
Public transport upgrades and new streetcars: Accessibility as a letting and exit lever
Local public transport is operated by Mainzer Mobilität (MVG) with a streetcar and bus network; the central hub is the main station with regional rail connections - a structural advantage for micro-locations close to railroad stations and axes. Stadtwerke is pushing ahead with the expansion under the "M for Future" program: construction is underway on the new Binger Straße streetcar line (scheduled to go into operation in 2026), the inner-city route received a decision in principle on routing in 2025; investments are also underway to connect the Heiligkreuz district, the university hospital and parts of Weisenau/Hechtsheim/Laubenheim-potential value drivers along future corridors. In addition, 22 new streetcars have been ordered (planned commissioning from 2028) to increase capacity, accessibility and energy efficiency - a clear boost to quality and demand for rail-based living. At the same time, the municipal local transport plan is being updated with participation phases for 2025, which should further structure frequencies, routes and junction quality.
City center update (IEK) and ESG levers: plannable framework for repositioning
Mainz is updating the Integrated City Centre Development Concept (IEK): the update, which was launched in 2025, combines existing concepts with new requirements (climate adaptation, digitalization) and prioritizes projects that can be implemented - a reliable basis for access to funding, quality of stay and mixed use in 1A/1B locations. The state supports the strengthening of the city with project funds (2025: around €380,000), which catalyzes private investment in EC activation, open space and climate adaptation measures. Investment model: Core in refurbished, inner-city and public transport-strong stock along existing and planned streetcar corridors for low fluctuation and predictable cash flows; value-add via energy modernization, efficient heat/ PV as well as floor plan and first floor repositioning in prioritized inner-city/corridor locations - secured by the documented population order and the structural mobility upgrade path.
