The topic briefly and concisely
In Germany, the comparative value, cost value, and income value methods are the three legally recognized methods for real estate valuation, as regulated in the ImmoWertV.
The choice of the right valuation methodology depends on the type of property (e.g., owner-occupied, rented) and the reason for the valuation (e.g., sale, inheritance).
A professional assessment by experts or AI-powered tools can prevent financial misjudgements and helps to determine the optimal value.
Determining the correct property value is often complex and dependent on many factors. In Germany, three main methods are legally established: the comparative value, the cost value, and the income value methods. Each of these valuation methods has specific areas of application and considers different aspects of the property, from location to income potential. A solid understanding of these methods is essential in order to obtain a realistic assessment and avoid costly mistakes. This article highlights the individual methods and their practical application, so you can better understand the value of your property and make informed decisions.
Fundamentals of Property Valuation: Why a Solid Methodology is Crucial
A property valuation may be necessary for a variety of reasons, such as a sale, an inheritance, or as collateral for a loan. The determined value forms the basis for financial decisions and negotiations. In Germany, the procedures for property valuation are regulated by the Immobilienwertermittlungsverordnung (ImmoWertV) and the Baugesetzbuch (BauGB). These legal provisions ensure that valuations are understandable and comparable. Choosing the right valuation methodology is already the first step towards a successful transaction or asset assessment. An inaccurate valuation can lead to financial disadvantages of up to 15%. Therefore, knowledge of the different approaches is equally important for owners and investors. The following will detail the three central methods.
The comparative value method: Market proximity through direct price comparisons
The comparative value method determines the value of a property by comparing it with recently sold, similar properties. This method is considered particularly market-oriented and is often used for owner-occupied residential properties such as single-family homes and condominiums, as well as undeveloped land. Key factors include similarities in location, size, features, condition, and year of construction of the comparison properties. The data basis comes from the purchase price collections of local expert committees, which record all notarised real estate sales. An adequate number of at least 3 to 5 comparison properties is necessary for a valid assessment. If there are not enough direct comparison cases, indirect comparisons or standard land values can also be used. This procedure reflects the current market situation as it is based on actual achieved prices. For a precise valuation, the quality of the comparative data is crucial. The challenge lies in finding suitable properties and properly accounting for deviations with adjustments of up to 30-35%.
The asset-based approach: Focus on intrinsic value
The cost approach method is applied when there are no sufficient comparable properties available or in cases of owner-occupied properties where income generation is not the primary focus. Typical use cases include single-family and two-family homes or special properties such as industrial buildings. In this valuation methodology, the land value and the value of the buildings (building substance value) are determined separately and then added together. The land value is usually derived from the standard land value. The construction costs of the building, reduced by the depreciation due to age, determine the building substance value. The normal construction costs (NHK 2010 or later) serve as the basis for calculating the construction costs. A market adjustment factor considers the current market conditions. The procedure is highly standardised and regulated in §§ 35-39 ImmoWertV. It provides a value that reflects the pure replacement costs. Typically, the determination of the intrinsic value is carried out in five steps.
The steps to determine the intrinsic value are:
Calculation of land value: plot area multiplied by the standard land value per m².
Calculation of building construction costs: normal construction costs per m² multiplied by the gross floor area.
Calculation of building substance value: building construction costs minus depreciation due to age.
Calculation of preliminary intrinsic value: building substance value plus land value.
Determination of the final intrinsic value: preliminary intrinsic value multiplied by the market adjustment factor.
Although it reflects the substance well, the market relevance can sometimes be lower than with the comparable value method. Therefore, it is often used in combination with other methods for plausibility testing.
The Income Approach: Yield Potential as a Measure of Value
The income approach is the preferred valuation method for income-generating properties, such as real estate assets intended for generating revenue. This includes rented multi-family houses, office buildings, or commercial properties. Central to this approach is the sustainable net income achievable from the property. This income is capitalised to determine the value of the structural facilities. The land value is determined separately, usually through the comparative value method, and added to the capitalised value of the structural facilities. A central factor is the property interest rate, which reflects the investment risk and is determined by the expert committees. The calculation steps include the determination of the annual net income (gross annual income minus non-recoverable operating costs), land value interest, and capitalisation of the building net income over the remaining useful life. The legal basis can be found in §§ 17-20 of the ImmoWertV. This method is complex but provides investors with a crucial metric on the profitability of an asset. A professional appraisal is often essential here.
Key components of the income approach are:
Determination of the land value (often through standard land values).
Calculation of the gross annual income (typical rental income).
Deduction of operating expenses (administration, maintenance, vacancy risk) results in the annual net income.
Calculation of land value interest (land value multiplied by the property interest rate).
Deduction of land value interest from the annual net income results in the building net income.
Capitalisation of the building net income with a multiplier (dependent on remaining useful life and property interest rate) results in the capitalised value of the structural facilities.
Addition of land value and capitalised value of the structural facilities results in the preliminary capitalised value.
Consideration of other value-influencing factors (e.g., building damage).
The accuracy greatly depends on the realistic assessment of future income and the property interest rate.
The choice of the right evaluation methodology and the role of experts
The selection of the appropriate valuation methodology depends on the type of property and the purpose of the valuation. For owner-occupied single-family homes, the cost value method or, if sufficient data is available, the comparable value method is often the first choice. For condominiums, the comparable value method dominates. For investment properties, the income value method is essential. Often, appraisers apply two methods in parallel for plausibility and greater accuracy. The real estate valuation ordinance (ImmoWertV) forms the legal framework for all three mentioned methods. Given the complexity and financial implications, it is often advisable to consult a qualified expert or a digital valuation tool like Auctoa ImmoGPT. Experts can correctly assess the specific characteristics of a property and ensure an objective valuation according to quality standards. A well-founded valuation protects against poor decisions and provides a solid basis for negotiations, often saving costs of several thousand euros.
Conclusion: Sound evaluation methodology as the key to success
The correct application of the appropriate valuation methodology is crucial for a realistic assessment of your property's value. Whether it is the comparison value method, the intrinsic value method, or the income value method – each method has its validity and specific application fields defined in the ImmoWertV. Knowing these methods enables you to better assess valuation offers and make informed decisions. A professional valuation by experts or AI-supported tools like those from Auctoa can help you achieve the optimal value and minimize risks. This is especially important in complex situations such as inheritances or investment decisions, where six-figure sums are often at stake. Take advantage of data-driven valuation options to successfully manage your real estate matters.
