Nettomietrendite
Nettomietrendite: Nettomietrendite (German for net rental yield) is the share of your total investment (purchase price plus closing costs) that remains as annual rental income after non-recoverable costs are deducted. It is more meaningful than the Bruttomietrendite (gross rental yield) because it accounts for management costs and maintenance reserves.
What is Nettomietrendite (net rental yield)?
Nettomietrendite is German for net rental yield. It is a metric for property investors that shows the real return a rented property earns once ongoing management costs are deducted. Unlike the Bruttomietrendite (gross rental yield), it accounts for both the non-recoverable costs on the income side and the closing costs (Kaufnebenkosten) on the investment side.
The formula is: net rental yield (%) = (annual cold rent − non-recoverable costs) ÷ (purchase price + closing costs) × 100. Non-recoverable costs are all the expenses a landlord may not pass on to the tenant under Section 1 (2) BetrKV: management costs, the maintenance reserve (Instandhaltungsrücklage), and vacancy risk. The annual cold rent (Jahreskaltmiete) is the base rent for a full year, before any utilities.
That makes the net yield a far more realistic measure than the gross yield. It is the standard figure professional investors and German banks use to assess investment property. Across Germany's 50 largest cities, the average gross rental yield was around 4.1% in the second half of 2025. The average net rental yield came in noticeably lower, at roughly 3.0 to 3.5%, because management and maintenance eat meaningfully into the rent.
Calculating the Nettomietrendite: an example
Starting point: condominium in Leipzig, 65 m², purchase price €195,000
| Item | Amount |
|---|---|
| Purchase price | €195,000 |
| Closing costs (Sachsen: 3.5% GrESt + 1.5% notary/land registry + 3.57% agent = 8.57%) | €16,712 |
| Total investment | €211,712 |
| Item | Amount/year |
|---|---|
| Annual cold rent (€9.50/m² × 65 m² × 12 months) | €7,410 |
| − Management costs (WEG property manager, approx. €30/month) | −€360 |
| − Maintenance reserve (€10/m²/year × 65 m²) | −€650 |
| − Vacancy risk (approx. 2% of annual cold rent) | −€148 |
| Net rental income | €6,252 |
Net rental yield = €6,252 ÷ €211,712 × 100 = 2.95%
For comparison, the gross rental yield of the same flat is €7,410 ÷ €195,000 × 100 = 3.80%. The net yield therefore sits 0.85 percentage points below it.
Key facts to keep in mind
- More realistic than the gross yield: The gross rental yield hides every running cost and the costs of buying. The net rental yield reflects the actual earnings position much more accurately.
- Non-recoverable costs vary: For new builds, maintenance reserves often run €5 to €8/m²/year; for older buildings €10 to €15/m²/year. That gap can shift the net yield by 0.3 to 0.5 percentage points.
- Mind the financing rate: Ideally the net rental yield should sit above your financing interest rate. With rates of 3.3 to 3.8% in early 2026, a net yield below that means the investor has to bank on capital appreciation to make the deal pay off over the long term.
- Tax effects are not included: The net rental yield reflects neither income tax on rental income nor tax benefits such as building depreciation (Gebäudeabschreibung, AfA). For a full return analysis you need the after-tax return on equity (Eigenkapitalrendite).
- Regional differences: In major cities (München, Hamburg, Frankfurt) net yields of 2.0 to 2.5% are typical; in mid-sized cities 3.0 to 4.0%; in structurally weaker regions above 4.5%. Higher yields usually come with higher vacancy risk, though.
Legal basis
The line between recoverable and non-recoverable costs is set out in the Betriebskostenverordnung (BetrKV, the Operating Costs Ordinance). Section 1 (2) BetrKV expressly excludes management costs along with maintenance and repair costs from the definition of operating costs. These costs stay with the landlord and so reduce the net rental yield. The right to pass operating costs on to the tenant comes from Section 556 of the Bürgerliches Gesetzbuch (BGB, the German Civil Code) together with the BetrKV. Section 2 BetrKV provides an exhaustive list of which costs are recoverable (17 categories, from property tax (Grundsteuer) to other operating costs).
Frequently asked questions
Nettomietrendite is German for net rental yield. It is the return a rented property generates after non-recoverable running costs, measured against your total investment: the purchase price plus closing costs (Kaufnebenkosten). Because it captures both ongoing costs and the cost of buying, it gives a far more realistic picture than the gross rental yield (Bruttomietrendite), which is why professional investors and banks rely on it. In Germany net rental yields often fall between 2 and 4%.
The Bruttomietrendite (gross rental yield) measures the annual cold rent (Kaltmiete) against the purchase price and ignores all running costs. The Nettomietrendite instead deducts every non-recoverable cost (management, maintenance reserve, vacancy risk) from the annual cold rent and also adds the closing costs (Kaufnebenkosten) to the denominator. In practice this puts the net yield roughly 0.8 to 1.5 percentage points below the gross yield. For a sound investment decision, the Nettomietrendite is the far more reliable figure.
As a rule of thumb, a rented property usually pays off as an investment from about 3.5 to 4% net rental yield. In Germany's seven largest cities (the A-Städte) net yields average 2.0 to 2.5% in 2025/2026, while B and C cities reach a realistic 3.5 to 4.5%. Structurally weaker regions can top 5%, though the vacancy risk is higher there. What matters most is that the net yield sits above your financing interest rate, so the investment produces a positive cash flow.
You deduct all non-recoverable costs, meaning expenses the landlord cannot pass on to the tenant. These include management costs (WEG property-manager fees, account handling), the maintenance reserve (Instandhaltungsrücklage), the cost of vacant months, and non-recoverable repairs and refurbishment. Section 1 (2) of the Betriebskostenverordnung (BetrKV, the Operating Costs Ordinance) expressly excludes these items from operating costs. For a condominium they typically run €1 to €2 per square metre per month.
