The topic briefly and concisely
The property valuation in Germany is based on the BauGB and the ImmoWertV, which prescribe three recognised methods: the comparative, income, and cost approaches.
Important factors influencing property value include location, condition, features, and the current market situation; these can influence the value by over 30%.
In the event of inheritance, a qualified market value appraisal can reduce the tax burden by up to 50% and prevent disputes among heirs.
The value of a property is not just a matter of subjective feeling; it's the result of a complex analysis. Especially in emotional situations such as an inheritance or important sales decisions, an objective valuation is indispensable. Incorrect assessments can quickly lead to losses in the five-figure range. This article explains the legal foundations, the recognised valuation methods, and the main influencing factors. Learn how to understand the backgrounds of the valuation and use them to achieve your goals, gaining financial security and making informed decisions with up to 100% certainty.
Legal Guidelines: Mastering the Foundation of Every Property Valuation
Are you aware of the legal foundations that substantially determine the value of your property? The Federal Building Code (BauGB), particularly § 194, defines the market value as the price that could be achieved in the ordinary course of business. The Property Valuation Ordinance (ImmoWertV) specifies these requirements and regulates the applicable valuation methods. Since the amendment in 2022, previous guidelines are now binding regulations, increasing transparency by at least 25%. These regulations ensure that valuations are carried out in a comprehensible and uniform manner throughout Germany. An understanding of these legal frameworks is the first step towards a solid valuation. Compliance with these standards is mandatory for expert reports submitted to authorities such as the tax office. Without this foundation, you risk a valuation that deviates by up to 30%, potentially to your disadvantage.
Focus on Evaluation Methods: Safely Applying the 3 Recognized Techniques
In Germany, three main approaches are standardised for determining the market value. The comparison method analyses actual sale prices of similar properties and is often used for residential real estate, ensuring a market proximity of over 90%. The income-based approach is central for yield properties, such as apartment buildings, and is based on the future expected returns, with the interest rate playing a key role. The cost approach determines the costs of new construction and is applied to owner-occupied properties or when no comparable data is available; here, construction costs of, for example, €1,800/m², are a basis for calculation. The correct choice and application of the appropriate valuation method is crucial for a realistic outcome. A wrong method can skew the value by 10-15%. The ImmoWertV provides clear guidelines on which method to use in which situation, ensuring that the determined value reflects the specific characteristics of your property.
The selection of the right method depends on several criteria:
Comparison method: Ideal when there is a sufficient number (at least 5-10) of current sales cases of comparable properties.
Income-based approach: Indispensable for rented properties, where rental income of, for example, €12,000 a year determines the value.
Cost approach: Sensible for specialised properties or when fewer than 3 comparables are available.
Combination: Often, two methods are combined to increase the plausibility of the result by 100%.
This methodological variety enables precise adaptation to every type of property and valuation situation.
Value Drivers and Detractors: Know and Utilize the Top 5 Influencing Factors
The value of your property is determined by a multitude of factors. Location is often the most important aspect; good connectivity can increase the value by up to 20%. The condition and age of the property also play a major role; modernisations can increase the value by 15-25%. The fittings, from the type of heating to the quality of flooring, also influence the price – a high-quality kitchen can mean 5% more in value. The current market situation, i.e., supply and demand, can cause regional price differences of over 30%. Let's not forget legal conditions such as registered charges or listed building status, which can reduce the value by 10% or more. A thorough understanding of these factors for property valuation is essential. An energy-efficient renovation, for example, can not only maintain the value but also increase it by up to 25%. Knowing these details helps you to realistically assess the value of your property.
Special Case Inheritance: Avoid Pitfalls and Optimise Taxes with Savings of up to 50%
Especially in the case of inheritance, a precise property valuation is invaluable. The tax office often sets the value arbitrarily, which can lead to inheritance tax being up to 50% too high. A qualified market value appraisal, prepared according to § 194 BauGB, can help alleviate this and significantly reduce your tax burden. An impartial appraisal serves as a solid foundation for negotiations with the tax office and among co-heirs. It provides clarity about the actual market value and prevents disputes that often incur costs of several thousand euros. The cost of such an appraisal, starting at around 1,500 euros, is usually money well spent. For heirs, it is crucial to know the valuation steps precisely. A certified appraiser takes all relevant aspects into account and provides a value that holds up in court. This is particularly important if a community of heirs wishes to divide or sell a property fairly.
The following points are particularly important in the event of inheritance:
Deadlines: Observe the deadlines for submitting the inheritance tax declaration, often just a few months.
Choice of appraiser: Rely on certified experts (e.g., according to DIN ISO 17024), whose appraisals are recognized by the tax office.
Documents: Provide all relevant documents (land register extract, building plans, etc.) for a prompt evaluation – this can shorten the processing time by up to 2 weeks.
Procedure: Depending on the type of property (e.g., rented or owner-occupied), the appropriate valuation method is applied, which determines the value 10-20% more accurately.
Tax optimization: A lower, but correct value can reduce the tax burden by thousands of euros.
An active approach protects your assets and ensures family harmony.

FAQ
What are the reasons behind the evaluation?
The background of the valuation encompasses the legal regulations (BauGB, ImmoWertV), the recognised valuation methods (comparison, income, cost approaches), and the various factors (location, condition, market) that determine the market value of a property.
How long is a property appraisal valid for?
A property appraisal has no fixed expiry date. Since market conditions and the condition of the property can change, it is recommended to update it every 2-3 years, especially if you intend to sell or if there are significant market changes.
What does a market value appraisal cost?
The costs for a market value appraisal vary depending on the type of property, scope, and effort involved. For a detached house, you can expect costs starting from around 1,500 euros, which corresponds to approximately 0.5% to 1% of the property's value.
Can I appraise my property myself?
An initial assessment is possible, for example, via online tools or comparison portals. However, for a legally sound, detailed evaluation that is recognised by banks or tax authorities, an appraisal by a qualified expert with at least 5 years of experience is necessary.
What is the best evaluation method?
There is no ‘best’ method; the choice depends on the type of property and the purpose of the valuation. The comparative method is often suitable for flats, the income method for rental properties, and the cost method for special properties. Often, two methods are combined for higher accuracy of up to 100%.
