The topic briefly and concisely
Property valuation in Germany is based on the BauGB and the ImmoWertV, which define the market value and valuation procedures.
Three primary methods are used: the comparative value, income value, and asset value methods, depending on the type of property and the reason for the valuation.
A professional assessment by experts or AI tools is crucial due to the complexity and data requirements for a market-relevant evaluation.
Determining the correct value of a property is equally crucial for owners, heirs, and investors. Whether for a sale, an inheritance matter, or an investment decision – a transparent and comprehensible valuation guide is essential. This article explores the legal foundations, introduces the common valuation methods, and explains why a professional valuation by experts like Auctoa helps you avoid costly mistakes and make data-driven decisions. With our ImmoGPT chat, you also receive an initial assessment.
The Foundation: Legal Principles of Property Valuation
Property valuation in Germany is not an estimation process, but is based on solid legal guidelines. The Building Code (BauGB) defines the fair market value (§ 194 Market Value) as the price that could be obtained in the ordinary course of business at a specific point in time. This definition is the central pillar for every professional property valuation. The Ordinance on Property Valuation (ImmoWertV) specifies these guidelines and came into force in its updated form on 1 January 2022. It consolidates previous guidelines and provides detailed regulations on the applicable methods and the necessary data. This ensures a nationwide uniform, market-oriented, and legally secure valuation of properties. Understanding these fundamentals is the first step in any valuation guide. The complexity of these regulations highlights the necessity of expert advice to avoid financial disadvantages.
The three pillars of valuation: An overview of the methods
A comprehensive assessment guide must explain the three standardised valuation methods in detail. The ImmoWertV outlines the comparative value method, the income value method, and the intrinsic value method. The choice of the appropriate method depends on the type of property and the reason for valuation. For owner-occupied properties and plots of land, the comparative value method is often the method of choice. For investment properties, such as rented multi-family houses or commercial real estate, the income value method takes precedence. The intrinsic value method is often used for owner-occupied single and two-family houses or special properties without sufficient comparative data. A qualified appraiser will often apply at least two methods to achieve a reliable result. This methodological diversity ensures a market-appropriate valuation.
The Comparative Value Method: What the Market Really Pays
The comparative value method (§ 15 ImmoWertV) is considered particularly market-oriented because it is based on actual purchase prices of similar properties. The value of your property is derived directly from market activity here. Appraisal committees collect and anonymise property purchase contracts for this purpose. The following aspects are used for a precise evaluation:
Location, size, and shape of the plot
Type, year of construction, features, and condition of the building
Energy characteristics and level of modernisation
Legal conditions such as registered burdens
If there aren’t enough direct comparable properties available, the indirect comparative value method is applied, which relies on average values and conversion coefficients. This method is particularly suitable for standard properties such as condominiums or terraced houses in areas with many transactions. A professional valuation in individual steps is crucial here. The challenge lies in finding a sufficient number of genuinely comparable properties, which often only experts with access to comprehensive databases can achieve.
The Income Approach: Focus on Return Potential
When it comes to rented or leased properties, the Income Capitalisation Approach (§§ 17-20 ImmoWertV) is the key for determining value. The focus here is on the sustainably achievable net income, which is the rental income minus the non-recoverable operating costs. The calculation is carried out in several steps:
Determination of land value (often through standard land value).
Calculation of the annual gross income (market rent).
Deduction of operating costs (administration, maintenance, risk of rental loss) results in net income.
Calculation of land value interest amount (land value x property interest rate).
The building net income (net income minus land value interest) is capitalised over the remaining useful life.
Adding land value and capitalised building net income results in the preliminary income value.
The property interest rate, which reflects the typical market return of comparable properties, plays a central role. This section of the valuation guideline demonstrates: The Income Capitalisation Approach is complex and requires comprehensive market knowledge to develop realistic valuation strategies. Auctoa’s ImmoGPT can assist you in getting an initial assessment of your property's income potential.
The tangible asset method: Evaluating substance and production costs
The capitalised value method (§§ 21-23 ImmoWertV) focuses on the substance of a property. It is often used for owner-occupied properties for which there are scarcely any comparable prices or rental income, such as single-family homes in rural areas or specialised properties. The basic idea is: What would it cost to construct the property anew today? The calculation includes the following components:
Land value: Determined based on guideline land values.
Building capitalised value: Based on standard construction costs (NHK 2010), adjusted for construction price indices.
Depreciation: Considers the age and remaining useful life of the building.
Value of outdoor facilities (e.g. garages, paths).
The preliminary capitalised value (sum of land value and building capitalised value including outdoor facilities) is then adjusted to the current market situation using a capitalised value factor (market adjustment factor). This factor is determined by expert committees and reflects the ratio of purchase prices to the calculated capitalised values. A detailed quality standard for appraisals is essential in this context. The complexity lies in the correct application of the NHK and the realistic assessment of depreciation.
Assessment Guide in Practice: Why a Professional Evaluation is Indispensable
An informed valuation guide highlights the complexity of real estate valuation. Errors in determining value can lead to significant financial losses, whether through a sale price that is too low or a tax burden that is too high. Private property owners and even experienced investors often reach their limits when it comes to obtaining current market data, correctly applying the procedures, or considering all factors affecting value. The Real Estate Valuation Ordinance (ImmoWertV) and the Building Code (BauGB) provide the framework, but their interpretation and application require expertise. A professional appraiser or an AI-supported valuation tool such as the one offered by Auctoa draws on current data and applies the procedures in conformity with models. This ensures an objective and market-appropriate valuation. Use helpful tools for precise valuation determination.

Conclusion: With the right evaluation guide to the fair value
What is the difference between traffic value and market value?
In Germany, the terms traffic value and market value are used synonymously.

What documents are needed for a property valuation?
Typically, a current land registry excerpt, building plans (floor plans, sections), a living space calculation, energy certificate, proof of modernization, and for rented properties, rental contracts and a breakdown of additional costs are required for a property valuation.
How long is a property value appraisal valid?
A property value appraisal always refers to a specific valuation date. As market conditions can change, an appraisal loses its relevance over time. For legal or tax purposes, a current appraisal (not older than 6-12 months) is often required.
How much does a professional property valuation cost?
The cost of a professional property valuation varies depending on the type and scope of the appraisal, the complexity of the property, and the region. A simple brief appraisal can cost a few hundred euros, while a detailed traffic value appraisal for legal purposes can cost 1,500 euros or more.
Can I evaluate my property myself?
You can make an initial assessment, but for a reliable and market-oriented evaluation that is also recognized by third parties (e.g., banks, tax office), it generally requires a qualified appraiser or a professional valuation tool like those provided by Auctoa due to the complexity of the procedures and the necessary market data.
What role does the standard land value play in a valuation guideline?
The standard land value is an important component of a valuation guideline. It is an average value for the land in a specific location and is determined by expert committees. It is incorporated into all three main valuation methods (comparison, income, and material value methods) for determining the land value.
