If you own a rental apartment inside a WEG (Wohnungseigentümergemeinschaft), you’re already familiar with the WEG-Verwaltung, which covers common property. But the management of your individual unit, including finding tenants, collecting rent, and handling repairs inside the apartment, is a separate service called Sondereigentumsverwaltung (SEV), sometimes referred to as Mietverwaltung for individual WEG units.
Over the past five years, SEV fees have risen significantly. Here’s what happened, why, and what it means for your bottom line.
What Sondereigentumsverwaltung actually covers
SEV is the management of everything inside your unit that falls outside the WEG’s responsibility. A typical SEV contract includes:
- Tenant search and selection including advertising, viewings, and credit checks
- Lease drafting and signing (Mietvertrag)
- Rent collection and monitoring (Mietinkasso, Mahnwesen)
- Nebenkostenabrechnung for your unit (operating cost statement)
- Coordinating repairs inside the apartment, excluding common areas handled by the WEG-Verwalter
- Tenant communication covering complaints, requests, and move-in/move-out
- Deposit management (Kaution)
- Handover protocols (Übergabeprotokoll)
What’s not included, and billed separately as Sonderleistungen, typically involves:
- Tenant changeover (Mieterwechsel), including new lease, advertising, and viewings
- Court proceedings or eviction coordination
- Major renovation supervision inside the unit
- Insurance claim handling (Schadenabwicklung)
The line between standard and extra services varies by contract. Always check the Leistungskatalog before signing.
How SEV fees have developed: 2021–2026
SEV fees have climbed steadily, but the pace accelerated sharply from 2023 onward.
The numbers
| Year | Avg. SEV fee (with WEG) | Avg. SEV fee (without WEG) | Notes |
|---|---|---|---|
| 2021 | ~20–22 €/unit/month | ~26–28 €/unit/month | Post-WEG-Reform baseline |
| 2022 | ~21–23 €/unit/month | ~27–30 €/unit/month | Moderate increases |
| 2023 | ~23–25 €/unit/month | ~30–33 €/unit/month | Inflation catch-up begins |
| 2024 | ~25–28 €/unit/month | ~33–37 €/unit/month | Sharp jump, 10–16% annual increases |
| 2025/26 | ~27–30 €/unit/month | ~35–40 €/unit/month | New contracts pricing in higher baseline |
Fees shown are netto. All amounts are approximate national averages for medium-sized properties (10–50 units). Sources: CRES Verwalterentgeltstudie 2024/2025, VDIV Branchenbarometer, Hausverwalter-Vermittlung.de.
Average netto per unit/month (medium-sized properties)
The key distinction: with simultaneous WEG management (the same Verwalter handles your unit and the WEG) is significantly cheaper than engaging a separate SEV-Verwalter. When the WEG-Verwalter also handles your SEV, they already know the building, the house rules, and the service providers, so overhead is lower.
If you need a standalone SEV because your WEG-Verwalter doesn’t offer it or you want someone else, expect to pay 30–50% more per unit.
Small properties pay more
The per-unit economics of SEV punish small portfolios:
- 1–3 units: 35–50 €/unit/month, or minimum flat fees of 80–120 €/month
- 4–10 units: 28–35 €/unit/month
- 10+ units: 22–28 €/unit/month
Many Verwalter now set minimum monthly fees regardless of unit count. A single apartment that cost 22 €/month to manage in 2021 may now carry a 35–40 € minimum, an effective increase of 60–80%.
Regional differences
SEV fees vary by region, though the gap has narrowed:
- South Germany (Bayern, Baden-Württemberg): highest at ~36 €/unit/month
- North Germany: ~34 €/unit/month
- East Germany (Sachsen, Brandenburg, Thüringen): lowest at ~27–28 €/unit/month
- Major cities (Munich, Frankfurt, Hamburg): 15–25% premium over surrounding areas
Berlin sits in between. Historically at an East German price level, it is rapidly converging with West German rates as demand outstrips supply.
What’s driving the increases
1. The Verwalter shortage
Germany has gone from approximately 24,000 Hausverwaltungen to fewer than 22,000 in just a few years. Nearly 25% of open positions at management firms remain unfilled. Many small, owner-operated firms are closing as their founders retire without successors.
The result is a seller’s market. Verwalter can choose their clients, raise prices, and drop unprofitable properties. Small WEGs and single-unit owners are hit hardest, as they’re the first to be “selectively terminated” (selektive Kündigung).
2. WEG Reform 2020 ripple effects
The Wohnungseigentumsmodernisierungsgesetz expanded the WEG-Verwalter’s responsibilities and introduced a mandatory certification requirement since December 2023. While this primarily affects WEG management, it spills over into SEV:
- Verwalter who handle both WEG and SEV spread their increased overhead across all services
- The certification requirement drove some smaller operators out of the market entirely
- 20 hours/year of mandatory continuing education adds cost
3. Inflation and labor costs
Staff salaries in property management have risen 15–25% since 2021 as firms compete for qualified Immobilienkaufleute. Office rents, software licenses, and external service providers (craftsmen, cleaning, gardening) have all followed the general inflation trend.
4. CO2-Kostenaufteilungsgesetz (since January 2023)
The CO2 cost sharing law introduced a 10-step model that allocates carbon costs between landlord and tenant based on the building’s energy efficiency. For SEV-Verwalter, this means:
- Determining the energy classification of the building
- Calculating the landlord’s CO2 cost share
- Adjusting the Nebenkostenabrechnung accordingly
- Additional documentation and tenant communication
This is pure additional work that didn’t exist before 2023.
5. Digitalization costs
Modern owners expect online portals, digital document access, and real-time financial reporting. The software platforms that deliver this (Casavi, ETG24, Facilioo, etc.) cost Verwalter over 1,000 €/month in licensing fees, costs that are passed through in higher management fees.
6. Heizungsgesetz (GEG) complexity
The updated Gebäudeenergiegesetz creates additional coordination requirements: heat pump assessments, hydraulischer Abgleich documentation, and energy-related renovation planning. Even for SEV, the Verwalter must understand how building-level energy decisions affect individual units and communicate with tenants accordingly.
Is SEV still worth it?
The math depends on your situation.
When SEV makes sense
- You live far from the property. Coordinating repairs and tenant issues remotely is painful.
- You have multiple units. Economies of scale kick in above 5–10 units.
- You don’t want to deal with tenants. Communication, Mahnung, and conflict resolution take real time.
- Your WEG-Verwalter offers SEV. Bundled pricing makes it significantly cheaper.
- Legal complexity. Nebenkostenabrechnung errors alone can cost more than a year of SEV fees.
When self-management makes more sense
- 1–3 units. SEV minimum fees erode a significant chunk of your net yield.
- You live nearby. You can handle viewings, key handovers, and minor repairs yourself.
- You’re comfortable with Mietrecht. Lease drafting, Nebenkostenabrechnung, deposit handling.
- You use management software. Tools like Vermietler, Vermietet.de, or objego handle the administrative burden at a fraction of SEV costs.
The breakeven calculation
For a single apartment renting at 800 € Kaltmiete:
| SEV | Self-managed (with software) | |
|---|---|---|
| Monthly cost | 35–40 € | 0–5 € |
| Annual cost | 420–480 € | 0–60 € |
| As % of annual rent | 4.4–5.0% | 0–0.6% |
| Yield impact (on 200K property) | -0.21 to -0.24% | negligible |
For a single unit, SEV consumes roughly a full month’s rent per year. That’s the equivalent of a 1-month vacancy, except it happens every year.
What to watch for in SEV contracts
If you do engage an SEV-Verwalter, pay attention to:
- Leistungskatalog. What’s included vs. what’s a Sonderleistung? Vague clauses like “weitere Leistungen werden gesondert berechnet” are a red flag.
- Mieterwechsel costs. Tenant changeover is the most expensive Sonderleistung, often 1–2 months’ rent. Clarify this upfront.
- Indexklauseln. Automatic fee increases tied to inflation indices can compound quickly.
- Contract term. Typical is 2–3 years with 3–6 months’ notice. Avoid long lock-ins with untested Verwalter.
- Nebenkostenabrechnung. Confirm this is included in the base fee. Some Verwalter charge it as extra.
- Minimum fees. If you have a single unit, ask explicitly about minimums.
The outlook
SEV fees will continue to rise. The structural drivers (Verwalter shortage, regulatory complexity, labor costs) are not reversing. The VDIV projects further fee increases of 8–12% for 2026.
For landlords with small portfolios, the trend points clearly toward digital self-management. The gap between what SEV costs and what software costs has widened to the point where the financial case for professional management only holds above a certain portfolio size, or when the owner simply doesn’t want to be involved.
The question is no longer whether you can manage your own rental unit. With modern tools, almost anyone can. The question is whether you want to, and whether the 400–500 €/year per unit is worth the convenience.
