Context

Interest rates in valuation

The market value is determined under § 194 BauGB by the price that could be achieved in the ordinary course of business on the valuation date. Decisive are the general value conditions on the valuation date: the totality of circumstances relevant to price formation, such as the general economic situation, capital market conditions and the economic and demographic developments of the area (§ 2 para. 2 ImmoWertV). They enter the valuation procedure through the input data and the market adjustment (§ 7 ImmoWertV).

§ 2 para. 2 ImmoWertV expressly names capital market conditions as part of the general value conditions. Capital market interest rates are, however, not the property yield (Liegenschaftszinssatz): this is derived under § 21 para. 2 ImmoWertV from purchase prices and net income of similar properties and contains market participants' expectations on rents, risks and value development. The relationship is nevertheless close: when financing costs and alternative yields rise, buyers demand higher initial yields, and the property yields derived from new sales cases rise with a delay.

  • If there is a marked interest rate movement between the evaluation period of the property yields and the valuation date, the suitability of the data must be checked and any adjustment justified (§ 9 para. 1 ImmoWertV).
  • In mortgage lending value assessment, capitalisation rates under the BelWertV apply; they are meant to reflect the long-term market development and deliberately do not follow short-term interest rate changes.
  • For valuation under IFRS 13 and for discounted cash flow methods, the federal bond yield is the starting point of the discount rate.

Background: Why mortgage rates rise: key rate, federal bonds and inflation.

Questions and answers

Frequently asked questions

Briefly answered, with source reference.

How high are mortgage rates currently?

The effective interest rate for new housing loans with interest fixation over 10 years was 2026 % in Aug 4.04, and 4.01 % across all fixation periods (Bundesbank MFI interest rate statistics, new business). The statistics are published with a delay of about six weeks; current offers of individual banks differ.

Why do mortgage rates follow the federal bond and not the key rate?

Banks refinance long-term loans mainly through covered bonds (Pfandbriefe), whose yields follow the federal bond of the same maturity. The key rate affects short maturities and only indirectly long ones.

Is the mortgage rate the property yield?

No. The property yield is a market variable derived from purchase prices (§ 21 para. 2 ImmoWertV) and is published by the expert committee. For residential property in sought-after locations it is often below the mortgage rate.

What does an inverted yield curve mean?

Short-term investments yield more than long-term ones. This occurs when the market expects falling key rates.
