South House Building

What South House Building does

Südhausbau is a Munich-based, family-owned residential real estate company founded in 1936, originally spun out of Münchner Bauunternehmung Karl Stöhr as the first private housing construction firm in Bavaria. It serves three primary customer groups — individual property owners and WEG communities requiring management services, residential tenants in its owned and managed portfolio, and end-buyers/investors purchasing newly built units — across Bavaria with additional operations in Berlin and Potsdam. The integrated offering spans WEG-Verwaltung (condominium management), Miethausverwaltung (rental and commercial property management), Sondermietverwaltung (tiered special rental management), Immobilienverkauf (brokerage), Immobilienbewertung (valuation), and Neubau & Projektentwicklung (developer/Bauträger services), with a Passivhaus construction standard and an income-subsidized (EoF) housing program in partnership with the State of Bavaria, Landkreis Ebersberg, and the municipality of Poing.

The technology stack is conventional rather than proprietary: a Casavi-based MyCasaVi customer portal (Android/iOS/desktop) for owner and tenant self-service, Matomo for web analytics, and OpenStreetMap for location display. The business model combines recurring streams (property management fees and rental income from a self-owned portfolio priced 15–20% below comparable market rents) with project-based revenue from developer sales of condominiums, row houses, and entire apartment buildings (typical project sizes 20–40 units). The company operates with an 80%+ equity ratio on its real estate assets, enabling capital-market independence, and is currently navigating a generational ownership transition managed by Geschäftsführer Hubertus Kobe.

Cumulatively, Südhausbau has delivered over 20,000 residential units across 25 Bavarian cities since 1936, housing approximately 55,000 people, and reports operational metrics materially better than industry averages — tenant turnover 20% below market, legal disputes one-third the industry rate, and employee tenure twice the industry benchmark. Distribution is multi-channel: direct sales, MyCasaVi portal, third-party listing on ImmoScout24, the educational 'Südhausbau erklärt' video series, and trade-fair participation (Expo REAL).

Revenue model

1. Property Management Fees: Südhausbau earns recurring management fees for residential (Miethausverwaltung) and commercial property management, as well as WEG management services. Services include bookkeeping, annual service charge statements, economic plans, maintenance coordination, and owner community administration. The company offers flexible management tiers: utility cost statement only, full commercial management, or full-service 'Rundum-Sorglos-Paket' including technical management, tenant selection, and rent optimization.
2. Rental Income from Owned Properties: Südhausbau retains ownership of residential units (built as developer or acquired) and generates recurring rental income. Rents for market-rate apartments are set 15–20% below comparable market rents. Income-subsidized (EoF) apartments offer lower but stable rental income with government co-funding.
3. Property Sales (Bauträger / Developer Sales): Südhausbau acts as a developer (Bauträger) purchasing land, planning, constructing, and selling residential properties (condominiums, row houses, semi-detached houses) to end-buyers. Sales are one-time transactions per unit. Project sizes typically range from 20 to 40 units. The company also conducts global sales of entire apartment buildings to investors.
4. Real Estate Brokerage / Property Sales Agency: Südhausbau provides property sales services for existing properties (not newly developed), charging brokerage fees for the full service of property marketing, buyer matching, and transaction management. This is handled by an in-house Makler team.
5. Real Estate Valuation: Südhausbau offers property valuation services as part of its holistic real estate offering, including Immobilienbewertung for existing properties and development properties.

Broad incumbents

• Vonovia SE: Germany's largest listed residential real estate company with a national portfolio of ~500,000+ apartments. Comparable to Südhausbau as a residential property owner, manager, and developer, but operates at vastly greater scale and is publicly listed.
• Deutsche Wohnen SE: Major German residential property company with a significant Berlin/Munich-area presence. Overlaps with Südhausbau in rental property ownership, WEG-style management, and new-build development, though at much larger institutional scale.
• LEG Immobilien SE: Listed German residential real estate company focused on North Rhine-Westphalia. Comparable business model (rental, management, development) but with a different regional focus and larger institutional footprint.
• TAG Immobilien AG: German residential real estate company with a focus on B-/secondary cities and portfolio acquisitions. Comparable in property management, rental, and value-add development services, with a broader geographic spread.
• PATRIZIA AG: German real estate investment manager with strong residential exposure and pan-European presence. Comparable in property/asset management, valuation, and residential investment services, with a much larger AUM base.
