Income approach

Income Approach - The income approach is a standardized valuation method under the Real Estate Valuation Ordinance (ImmoWertV), in which the market value of a property is derived from the sustainable rental income it can generate. It is primarily used for investment properties such as apartment buildings, commercial properties, and mixed-use properties.

What exactly does the income approach mean?

Along with the cost approach and the sales comparison approach, the income approach is one of the three recognized methods of real estate valuation in Germany. The basic idea is simple: A property is worth as much as it can generate in income. That is why the rental yield is at the center of the calculation-not the physical asset value of the building.

The calculation follows a clearly defined formula. First, the gross income is determined, i.e., the sum of all sustainable annual rental income. Operating costs are then deducted from this gross income-these include administrative costs, maintenance reserves, the risk of rent loss, and non-apportionable operating expenses. The result is the net income of the property.

In the next step, the net income is adjusted for the return on land value. The land value is determined separately using the comparative value method (typically based on standard land values) and multiplied by the property interest rate. The property interest rate is a standard market indicator derived by appraisal committees from actual purchase prices. For multi-family homes in Germany, it typically ranges between 3.0 and 5.0 percent; for commercial properties, it is often higher.

The net income, adjusted for the return on land value, is then capitalized using the multiplier (also known as the present value factor). The multiplier takes into account both the property interest rate and the economic remaining useful life of the building. The longer the remaining useful life and the lower the interest rate, the higher the multiplier. The result of this multiplication is the income value of the building, which, together with the land value, forms the total income value.

The legal basis is provided by Sections 27-34 of the ImmoWertV. Appraisal committees, banks, and experts use the income approach as the standard method when the expected return significantly determines the purchase price.

When is the income approach used?

The income approach is always the right choice when a property serves primarily as an investment. Typical applications include multi-family homes, mixed-use residential and commercial buildings, office buildings, retail spaces, and logistics properties. The method also plays a central role in the valuation of leasehold rights.

For owner-occupied single-family homes or condominiums, however, the income approach is less suitable, as personal utility influences the market price more strongly than the theoretical rental yield. In such cases, appraisers tend to rely on the cost approach or the sales comparison approach.

When financing investment properties, banks regularly require an income approach calculation to determine the mortgage lending value. Tax authorities also use a simplified version of the income approach for the tax valuation of real estate.

Limitations of the Income Approach

Despite its widespread use, the income approach has limitations: It assumes that the sustainable rents can be accurately determined. For properties with special uses (e.g., owner-occupied commercial properties, nursing homes, hotels), determining the rent is more difficult and prone to error. Furthermore, the method is sensitive to the choice of the property interest rate-an incorrect value leads to significant valuation errors. For properties with a very short remaining economic useful life, adjustments and corrections are necessary.

Practical Tip for Property Owners in Nuremberg and Franconia

In the Nuremberg metropolitan region, property interest rates vary considerably depending on location and property type. The City of Nuremberg’s Appraisal Committee regularly publishes current values in its real estate market report-this data serves as the most reliable basis for any income approach valuation. Anyone wishing to have a multi-family home appraised in Nuremberg, Fürth, or Erlangen should ensure that the appraiser uses regional market metrics.

Our network of experts recommends that owners of investment properties have the income approach value reviewed regularly-especially following rent adjustments, major renovations, or changes in the local rental market. This ensures you always maintain an overview of the actual market value of your investment in the region.

Frequently Asked Questions

What is the difference between the income approach and the cost approach?

The income approach derives the property value from the achievable rental income and is suitable for investment properties. The cost approach, on the other hand, calculates the value based on the building’s construction costs minus depreciation plus land value. It is primarily used for owner-occupied properties where no rental income is available as a basis for calculation.

Who determines the real estate interest rate?

The real estate interest rate is determined by local appraisal committees based on an analysis of actual purchase prices (purchase price database). It is published in the real estate market report and reflects the market-standard expected return for specific property types and locations. For Nuremberg and the surrounding counties, the appraisal committee publishes annually updated values.

Can I calculate the income value of my property myself?

A rough estimate is certainly possible using the basic data (annual net rent, operating costs, land value, remaining useful life, property interest rate). However, for legally sound valuations-such as for sales, financing, or tax purposes-we recommend engaging a certified appraiser who can accurately interpret regional market data and fully comply with ImmoWertV requirements.

How often should I have the capital value of my apartment building assessed?

We recommend an update every three to five years, as well as whenever significant changes occur: after major renovations, in the event of significant rent changes, or when a sale, refinancing, or inheritance is pending. The Nuremberg real estate market has developed dynamically in recent years-an outdated income approach valuation can lead to significant misinvestments or lost sales proceeds.

Income Approach in Inheritance and Gift Tax

In addition to determining market value, the tax office uses a simplified form of the income approach for inheritance and gift tax. According to Sections 182-188 of the German Inheritance Tax Act (BewG), the inheritance tax property value for rented properties is determined based on the annual gross income, a flat-rate deduction for management costs, and an official property interest rate. In many cases, this tax value deviates significantly from the actual market value-in tight markets such as Nuremberg, the tax assessment is often well below the actual market value.

Owners and heirs have the right to prove a lower market value to the tax office through an expert appraisal (Section 198 of the German Property Valuation Act). If the actual market value is below the tax-assessed property value-which is rare in practice but conceivable (e.g., for heavily leased investment properties below market rent)-an appraisal should be commissioned to correctly determine the tax base. We recommend that, in cases of inheritance involving significant real estate assets, an expert specializing in real estate valuation be consulted at an early stage and that the tax implications be discussed with a tax advisor.
