The topic briefly and concisely
The ImmoWertV is the central German regulation for property valuations and has integrated all relevant guidelines since 2022.
Publicly appointed and sworn experts (regulated by SVO) are essential for legally sound reports.
European Valuation Standards (EVS 2025) and EU Directives (EPBD, CSRD) are increasingly influencing valuation criteria, particularly sustainability.
The valuation of a property is a complex process that involves much more than just estimating the market value. Particularly in German-speaking areas and within the EU, there is a dense network of appraisal regulations designed to ensure transparency, comparability, and legal certainty. Whether for sale, inheritance, or financing, compliance with these regulations is crucial for property owners and professional investors. This article guides you through the most important German and European regulations, explains the various valuation methods, and shows you how to achieve an objective, data-driven property valuation. Discover how to avoid pitfalls and determine the true value of your property.
The Immobilienwertermittlungsverordnung (ImmoWertV) as a foundation
The Immobilienwertermittlungsverordnung, abbreviated as ImmoWertV, forms the central legal basis for the valuation of real estate in Germany. It defines mandatory procedures and principles to transparently determine the market value (traffic value) of land and buildings. Since 1 July 2010, it has ensured a uniform valuation practice.
With the amendment that came into force on 1 January 2022, former separate valuation guidelines (such as the Bodenrichtwertrichtlinie or Ertragswertrichtlinie) were fully integrated. This led to a significant streamlining and unification of appraisal regulations. The ImmoWertV prescribes three main procedures: the comparative value, income, and cost value methods. These standardised procedures are particularly important for appraisals submitted to courts or tax authorities and require high legal reliability. Compliance ensures the comparability of real estate values and is mandatory for at least 95% of legally binding appraisals. Precise application of these regulations is therefore essential for a certified valuation.
Role and Responsibilities of Experts according to the Expert Regulations (SVO)
For the preparation of real estate appraisals, especially when they require high legal binding, publicly appointed and sworn (ö.b.u.v.) experts are often indispensable. Their appointment and activity are regulated by the Expert Regulations (SVO). According to § 2 paragraph 1 SVO, only qualified persons may create appraisals relevant to legal disputes.
The SVO imposes high demands on the personal and professional suitability as well as on the independence and impartiality of the experts. An appraisal by an ö.b.u.v. expert enjoys special credibility with courts and authorities. Certification often follows the DIN EN ISO/IEC 17024 standard, which sets competency requirements for professionals. According to § 9 paragraph 3 SVO, experts must complete their assignments carefully, taking into account the current state of science and technology, and their results must be understandably justified. This ensures the quality and reliability of the appraisals, which is crucial for quality standards in appraisals. The costs for a sworn expert can amount to approximately 160 euros per hour.
European Standards: The European Valuation Standards (EVS)
Beyond national regulations, European standards are gaining significance. The European Valuation Standards (EVS), published by TEGoVA (The European Group of Valuers' Associations), have provided a consistent framework for real estate valuation in Europe since the 1980s. The tenth edition, EVS 2025, comes into effect on 1 January 2025.
This update responds to market developments and the increasing integration with EU law. Important innovations in EVS 2025 include:
Energy Efficiency: The new EVS 6 addresses market value determination in the context of EU-wide renovation obligations.
Capital Requirements: A new capital requirement regulation introduces a 'real estate value' based on 'prudent-conservative valuation criteria,' relevant for mortgage securities.
Sustainability: A revised section demonstrates the impact of the European Green Deal on valuation.
Agricultural Real Estate: This topic is revisited after 20 years, taking into account climate change and technology.
The EVS 2025 are an important tool for internationally operating investors and valuers and promote transparency across borders. Compliance with these valuation standards is often essential for cross-border transactions.
Influence of EU directives on assessment regulations
Alongside the EVS, various EU directives significantly shape the report requirements and valuation approaches. The EU has set clear goals for a more energy-efficient and climate-neutral building stock by 2050. This has direct effects on the property values.
The key directives include:
EPBD (Energy Performance of Buildings Directive): It enforces stricter energy requirements, including renovation obligations for the least efficient 16% of buildings by 2030/2033 and the ZEB standard (Zero Emission Buildings) for new constructions from 2030.
CSRD (Corporate Sustainability Reporting Directive): Large companies, including those in the real estate sector, must comprehensively report on sustainability aspects from the financial year 2024. This affects firms with specific revenue or employee thresholds.
EU Taxonomy: This classification system defines when an economic activity is considered "ecologically sustainable". This significantly influences financing and ESG ratings of real estate projects.
RED III (Renewable Energy Directive III): By 2030, at least 42.5% of energy consumption should come from renewable sources, which imposes requirements on new buildings.
These EU directives make sustainability aspects a central value factor. Non-compliance can lead to devaluations or even "stranded assets". It is therefore advisable for every property owner and investor to proactively consider these legal developments. For an initial assessment of how these factors might impact your property, a conversation with our ImmoGPT chat could be helpful.
The preparation of a compliant report
A property appraisal must not only be correct in content but also meet formal requirements to be recognised. The Chambers of Industry and Commerce (IHKs) provide recommendations based on the Expert Regulations (SVO), particularly § 9 para. 3 SVO. An appraisal should therefore be systematically structured, clearly organised, and logically justified.
In practice, a four-stage structure has proven effective:
Part 1: Cover page, general information, and assignment (including order content, evidence questions in court appraisals).
Part 2: Documentation of data (description of the object, documents used, on-site visit).
Part 3: Expert response to the question (evaluation, conclusions, application of assessment methods).
Part 4: Summary, signature, and official seal (for publicly appointed and sworn experts).
It is important to clearly separate the documentation of the data found from the expert assessment. All questions asked in the order must be answered without exceeding the scope of the order (overstepping the tenor). The conclusions must be comprehensible for a layperson without any gaps. Adhering to this structure is a key aspect to avoiding common mistakes.
Challenges and Solutions in Practice
The application of appraisal regulations presents challenges for property owners and even for professionals. The complexity of the frameworks and the constant adaptation to new market conditions and EU regulations require continuous training. One of the major challenges is the objectivity of the evaluation, as even with standardised procedures, there are opportunities for interpretation.
Choosing the right expert is crucial. While estate agents can often provide an initial market assessment, for legally binding or complex evaluations, it is advisable to hire a certified, ideally publicly appointed and sworn expert. The costs for a full appraisal can range from 1,000 to 2,500 euros, or up to 1.5% of the property's value.

FAQ
What appraisal regulations must I consider when selling real estate?
While a formal appraisal according to ImmoWertV is not always mandatory when selling, a realistic valuation is crucial. The procedures of ImmoWertV (comparison, income, and asset value methods) provide a solid foundation. An appraisal can strengthen the negotiating position and is recommended for complex properties or in case of disagreement.
Do I always need an appraisal according to appraisal regulations for inheritance tax?
The tax office often determines the value on a flat-rate basis. If this deviates significantly from the actual value, an appraisal by a publicly appointed expert according to ImmoWertV can help prove a lower, correct value and possibly save on inheritance tax.
What is the difference between ImmoWertV and EVS?
The ImmoWertV is a German regulation that prescribes legally binding procedures for real estate valuation in Germany. The EVS are European valuation standards that provide a uniform framework for valuations in Europe and are more of a guideline, but are gaining international significance.
How do I find a qualified expert who knows the appraisal regulations?
Pay attention to certifications (e.g., according to DIN EN ISO/IEC 17024) and public appointments by chambers of industry and commerce or chambers of architects. These experts are demonstrably qualified and obligated to comply with the SVO and ImmoWertV. Auctoa can help you find the right expert or obtain an initial AI-supported evaluation.
Do sustainability aspects play a role in current assessment regulations?
Yes, very much so. Both the EVS 2025 and EU directives such as the EPBD and EU Taxonomy place significant emphasis on energy efficiency and sustainability. These factors are increasingly considered in assessments and can substantially impact property values.
Are there alternatives to a formal appraisal?
Yes, for initial guidance or private purposes, there are online valuation tools or brief assessments from agents available. However, these are not legally binding. For official purposes (court, tax office), an appraisal according to ImmoWertV from a qualified expert is usually indispensable. The Auctoa ImmoGPT chat can provide you with an initial, data-based assessment.
