Calculating return on equity – property as an investment

calculate return on equity propertyproperty investment Dresdenleverage effect propertyrental yield equity

What is the return on equity for property?

The return on equity indicates how many percent return you earn per year on the equity you have put in — not on the total value of the property. Because of the leverage of borrowed capital, since you finance a large part through a loan, the return on equity can be considerably higher than the property's yield on the purchase price.

Property as an investment is rarely paid for with the purchase price — instead it is usually financed to a considerable extent through a loan. It is precisely this leverage that makes the return on equity so revealing: while a property throws off only 4 percent gross rental yield on the purchase price, the return on the equity put in can be a multiple of that. With the calculator below, you can see how much the tenant takes off your hands each month — and how your wealth grows over 20 years.

The leverage effect with property

Someone who buys a property costing 300,000 € and puts in 60,000 € of equity finances the loan of 255,000 € (purchase price plus incidental costs) through the bank. The decisive mechanism: the loan is not repaid out of your own pocket — but out of the rental income.

As long as rental yield > loan interest rate holds, the borrowed capital works for you. The property earns more than it costs — the difference strengthens your equity. This leverage is known as the leverage effect.

In concrete terms that means:

  • You put in 60,000 € (approx. 20 percent of the total price)
  • The property rises in value and the loan is paid down
  • After 20 years your equity (property value minus remaining debt) can be a multiple of the original sum
  • At the same time you have often carried only a fraction of the monthly instalment yourself

"The tenant pays the instalment" — what that really means

This sentence is not a marketing promise but an arithmetical truth — when the rental income is high enough. For a rented flat in Dresden at 900 € net cold rent and a loan instalment of 1,100 €:

  • Tenant carries: 900 € (approx. 82 percent of the instalment)
  • Owner carries: 200 € + running costs (service charge, maintenance)
  • The owner builds equity — through both repayment AND appreciation

The calculator shows exactly this split: the blue bar (the tenant's share) and the orange bar (your share) make visible who actually carries how much of the monthly costs.

Positive cash flow (rent exceeds the instalment plus running costs) is possible, but rare in strained markets such as central Dresden locations. More often the personal contribution is 100–400 € a month — given the long-term wealth-building, an acceptable contribution from the point of view of many investors.

Return on equity vs. direct investment

What if you invested the same 60,000 € directly instead — for example in a broadly diversified ETF with an assumed return of 5–7 percent p.a.? The return on equity of a debt-financed property can exceed this benchmark return, but does not have to:

Factor Property (debt-financed) Direct investment (ETF)
Leverage effect Yes (leverage through a loan) No
Inflation protection High (tangible asset) Moderate
Liquidity Low (tied-up capital) High
Tax treatment Depreciation, income-related expenses 25 % flat-rate withholding tax
Risks Vacancy, interest-rate change, maintenance Price fluctuations

For the typical Dresden investor with an investment horizon of 20+ years and a specific property in a good location, the return on equity is in many cases competitive — provided the financing and rent are carefully calculated.

FAQ

Frequently asked questions

What is the return on equity for property?
The return on equity indicates how many percent return you earn per year on the equity you have put in — not on the total value of the property. Because of the leverage of borrowed capital (you finance a large part through a loan), the return on equity can be considerably higher than the property's yield on the purchase price.
How is the leverage effect calculated for property?
When the rental yield (on the purchase price) is higher than the loan interest rate, the borrowed money works for you: part of the rental income repays the loan, and your equity grows faster than with pure self-financing. This leverage effect makes property an attractive investment even at moderate property yields.
What does it mean that the tenant pays the instalment?
With a well-let investment property, the net cold rent covers a large part of the monthly loan instalment. If the rent is higher than the instalment plus running costs, a positive monthly cash flow even arises. In any case, the tenant indirectly repays a substantial part of the debt — that strengthens your equity without you having to put up the full amount yourself each month.
Why only 1 percent appreciation in the calculator?
The calculator uses a conservative assumption of 1 percent p.a. property appreciation. Historically, value gains in Dresden have been considerably higher in some phases — but a forecast would be unserious. With 1 percent you get a cautious baseline; the actual return can deviate considerably depending on location, the development of the rental market and financing conditions.
When is property worthwhile as an investment in Dresden?
As a rule of thumb: when the net rental yield (annual rent minus running costs, divided by the purchase price including incidental costs) is at least 3.5–4 percent and the financing interest rate is below that, the leverage effect is positive. In Dresden, attractive investment properties in good districts have recently been available with a net rental yield of 3–5 percent.
