The topic briefly and concisely
The valuation in Germany is based on three standardised methods (comparative value, intrinsic value, and income value methods) according to the ImmoWertV, to ensure objective and comparable results.
The location (both macro and micro) is the crucial value factor and can cause price differences of over 300%, even before considering the property's condition and features.
For legally binding occasions such as inheritance or divorce, a market value appraisal according to Section 194 of the Building Code (BauGB) is essential, as online valuations only provide a rough guide and are not admissible in court.
The value of a property is not a fixed amount, but the result of a complex analysis. Many owners risk financial disadvantages because they rely on outdated data or their gut feeling. A professional property valuation protects you from misjudgments. It provides an objective, data-based foundation for sales negotiations, inheritance disputes, or planning your finances. We explain the three legally standardized methods and the seven most important value drivers so you can make well-informed decisions.
The 3 Pillars of Real Estate Valuation according to ImmoWertV
The Immobilienwertermittlungsverordnung (ImmoWertV) establishes three standardised methods for valuation in Germany to ensure high comparability. Each method is suitable for different types of property and valuation occasions. Choosing the correct method is the first step towards a reliable result and is determined by certified appraisers.
The ImmoWertV 2021 has consolidated previous guidelines and, since 1 January 2022, provides more uniform principles nationwide. This significantly increases transparency for property owners. Combining two methods can, in some cases, enhance the accuracy of the result by up to 15%. A well-founded market value appraisal is therefore essential for legally sound valuations.
Familiarity with these methods helps you better understand appraisals and ask the right questions. Below, each method is examined in detail.
Comparative valuation method: The market sets the tone
The comparative value method determines the value of a property by directly comparing it with recently sold, similar objects. The committees of experts in the municipalities collect these purchase prices and provide them for reference. This method is primarily applied to owner-occupied single-family houses and condominiums in areas with sufficient transaction data.
An expert adjusts the average price with premiums and deductions based on the specific characteristics of your property. These include, among others:
Location quality (e.g., micro-location premium of 5-10%)
Year of construction and condition (modernisations can increase the value by over 20%)
Features such as a balcony or garden
Energy condition according to GEG
The strength of this method lies in its high market proximity, as it is based on actual prices achieved. An online valuation often uses an automated form of this method, but can inadequately capture individual characteristics. Therefore, for an accurate valuation, an expert analysis that goes beyond pure database queries is essential.
Real Value Method: What the Substance Really Costs
In the cost approach, the central question is: What would it cost to construct the property anew today? It is typically applied to owner-occupied properties for which there are few comparable objects, such as architect-designed houses or industrial buildings. The real value comprises the land value and the construction costs of the buildings.
The calculation is carried out in three steps:
Determining the land value using the standard land value.
Calculating the standard construction costs for the building (NHK 2010).
Adjusting for depreciation due to age and other factors influencing value.
The preliminary real value is then adjusted to the current market situation using a cost multiplier to determine the market value. This multiplier is determined by local expert committees and can range from 0.8 to 1.5, depending on the region. A professional valuation report ensures that all components are correctly assessed.
Income valuation method: When the yield counts
The income approach is the method of choice for yield properties such as apartment buildings or commercial properties. It is based on the future expected income from renting and leasing. The focus here is clearly on the economic potential of the property for an investor.
The key calculation figures are the annual net income (gross annual income minus operating costs) and the property interest rate. The property interest rate reflects the regional market risk and is often between 2.5% and 3.5% in prime cities. A deviation of just 0.5 percentage points can already change the income value by over 10%.
The income value results from the capitalisation of the net income and the addition of the land value. The correct assessment of the achievable sustainable rent is the most critical factor here. A professional appraisal analyses rental contracts and compares them with the local rental index to make a realistic forecast.
Top 7 factors that significantly influence property value
Regardless of the valuation method, seven key factors determine the value of your property. Location is the most important lever and can result in price differences of over 300% between different neighbourhoods. However, the condition of the building's structure is also crucial; an energy-efficient renovation can increase the value by up to 25%.
Other important factors include:
Land: Size, layout, and buildability are decisive. The standard land value provides an initial guide here.
Building: Year of construction, living area, and the quality of the building's structure.
Features: A fitted kitchen, flooring, or a modern bathroom can increase the value by 5-10%.
Legal conditions: Encumbrances in the land register, such as a right of way, can reduce the value by more than 15%.
Energy condition: The energy certificate is mandatory and strongly influences demand.
A thorough analysis of these points is the first step towards a valid valuation. The complexity of these factors shows why a superficial online assessment often falls short.
The Location: Why the Site Dominates the Price
The old real-estate mantra 'Location, Location, Location' hasn't lost any of its validity. Experts differentiate between macro and micro locations. The macro location (city, region) defines the general price level, influenced by economic strength and demographics. For instance, properties in metropolitan areas like Munich are, on average, twice as expensive as those in rural areas.
The micro location (immediate neighbourhood) decides the final attractiveness. Good public transport connections can increase the value by 10%, while noise pollution can decrease it by up to 20%. Even within a single street, values can differ by more than 15%. Therefore, the assessment of land quality is a key component of any analysis.
Future developments such as planned infrastructure projects can further increase a location's potential. A digital tool like the Auctoa ImmoGPT can help you understand these complex relationships and recognise the potential of your property.

Free online calculators offer a quick initial orientation and generally use a simplified comparative value method. They are useful for an initial assessment, but their accuracy is limited, as individual characteristics often remain unconsidered. The deviation from the real market value can easily be 20% here.
A short appraisal by an expert costs from around 500 euros and provides a more in-depth analysis for a planned sale. For legal disputes (inheritance, divorce) or for submission to court, however, a comprehensive market value appraisal according to § 194 BauGB is mandatory. The costs for this range between 0.5% and 1.5% of the property value.
Investing in a qualified appraisal protects against costly mistakes. It not only provides a value but also a detailed justification that can secure you an advantage of up to 10% in negotiations. A detailed valuation report is the most secure basis for your decision.
Conclusion: Data beats gut feeling in value assessment
What is the difference between market value and fair market value?
These terms are often used synonymously. The fair market value is the legal term from the Building Code (§ 194 BauGB) and refers to the price that could be achieved in normal business transactions at a certain point in time. It is the result of a formal valuation.
How long does a property appraisal take?
The duration depends on the scope. A short appraisal can be completed within a few days. A comprehensive fair market value appraisal usually requires two to four weeks from commissioning to completion due to the detailed examination and documentation.
Can I determine the value of my property myself?
You can make an initial estimate by using real estate portals for comparable properties. However, laypeople lack access to official purchase price collections and the expertise to apply standardized procedures and market adjustments for a reliable and recognized valuation.
What documents are required for a valuation?
For a professional valuation, a current land register extract (no older than 3 months), building plans (floor plans, section drawings), a calculation of living space, the energy certificate, and for condominiums the declaration of division as well as the latest minutes of the owners' meetings are required.
When is a court-proof appraisal necessary?
A court-proof fair market value appraisal is required whenever the value must be definitively established in a legal procedure. This is typically the case for divorces, inheritance settlements, gifts (for the tax office), or in foreclosure proceedings.
Does a renovation always positively affect the value?
Generally yes, but not every investment pays off 1:1. Energy-efficient renovations and modernization of the bathroom and kitchen have the greatest positive effect. Luxury renovations that do not appeal to the broad masses do not always lead to a proportional increase in value.
