Report an inheritance to the tax office within three months to avoid penalties, and have its often overestimated value reviewed with a counter-appraisal.

A certified expert is essential for a legally sound assessment; online tools provide only an initial, imprecise guide.

The property value largely depends on location, energy efficiency, and renovation needs – factors often overlooked in a blanket estimate.

The valuation of an inherited property is an urgent and complex task for most heirs. Within only three months of becoming aware of the inheritance, you must report the value to the tax office, which forms the basis for inheritance tax. An inaccurate estimation can quickly lead to a tax demand that is 10-20% too high, as the tax office often sets blanket values. This article guides you through the necessary steps to have your inherited house valued quickly and easily, avoid financial disadvantages, and create a solid foundation for decision-making regarding sale, rental, or personal use.

  • Fristen beachten: Report the inheritance to the relevant tax office within three months to avoid surcharges.

  • Bewertungsmethode wählen: Depending on the type of property, the comparative value, asset value, or income value method may be applied.

  • Finanzamts-Bewertung prüfen: The tax office's standard valuation often exceeds the real market value; a counter-opinion can reduce the tax burden by up to 20%.

  • Experten-Hilfe nutzen: While online tools provide initial guidance, only certified appraisers deliver court-valid market values starting at approximately 2,800 euros.

  • Dokumente vorbereiten: Keep important documents like land registry extracts, building plans, and energy certificates ready for prompt valuation.

Following an inheritance, the tax office gives you a strict deadline of three months to report the estate. This report is crucial as it forms the basis for the calculation of inheritance tax. The tax office often uses standardised, general methods for assessment without conducting an on-site inspection. This approach can overvalue your property by 10% to 20%, directly increasing your tax burden. If you sell the house within a year, the achieved sale price can be presented to the tax office as a more realistic value. A well-founded market value appraisal for the tax office is therefore not a cost factor but an investment that can save thousands of pounds. Understanding these connections is the first step in strategically managing the assessment process.

Die Immobilienwertermittlungsverordnung (ImmoWertV) specifies three recognised methods in Germany. For owner-occupied single-family houses and condominiums, the comparative value method is usually applied, where sale prices of similar properties in the neighbourhood serve as a reference. For rented properties such as multi-family houses, the income value method is used, which calculates the value based on achievable rental income. The cost value method is employed for properties with few comparable objects; it adds up the building's construction costs and the land value. Choosing the correct method is crucial for a realistic value and fair taxation. An incorrect approach can lead to deviations of over 15%. The different property valuation methods lead to varying results, making expert analysis essential.

To quickly and easily assess an inherited house, there are several options with varying accuracy. Free online tools use public average data and provide an initial rough estimate in less than 30 minutes. This is useful for initial orientation but neglects individual factors such as refurbishment needs or specific location characteristics. Estate agents often offer free valuations, though these are typically aimed at quick sales and may not always be objective. For a legally compliant valuation recognised by courts and tax authorities, an appraisal by a certified expert is indispensable. The costs for this start at around 500 euros for a short appraisal and can rise to over 2,800 euros for a comprehensive market value report. Our digital valuation tool ImmoGPT combines the speed of an online tool with the accuracy of expert algorithms, providing you with a quick, data-driven analysis. This way, you can understand the advantages and disadvantages of each option and make the right choice for your situation.

A prompt assessment largely depends on the completeness of your documents. An appraiser needs at least 5 to 7 key documents to accurately determine the value. These include:

  1. Current land register excerpt: Provides information on ownership and encumbrances (e.g., right of way).

  2. Extract from the cadastral map: Shows the exact location and boundaries of the property.

  3. Building plans and floor plans: Document the calculation of living and usable areas (scale 1:100).

  4. Energy Performance Certificate: Mandatory since 2008; a poor energy efficiency rating can reduce the value by up to 30%.

  5. Evidence of modernisations: Invoices from the past 10-15 years demonstrate value-enhancing measures.

  6. Living and usable area calculation: The exact square footage is a crucial value factor.

Good preparation can speed up the process by up to two weeks. A comprehensive checklist helps you to remember everything and avoid delays. With complete papers, the next step, the actual analysis, can begin efficiently.

The final market value is influenced by dozens of factors. The location (macro and micro) is the most important value driver, accounting for around 40%. However, the condition of the building fabric is also crucial. A high need for renovation, especially for properties in energy efficiency class E or lower, can reduce the value by more than 20%. More than 40% of properties in Germany have significant renovation needs. On the other hand, a modern interior, good energy condition (classes A, B), and contemporary layout can increase the value. Legal aspects such as a registered right of residence or usufruct can reduce the value by 20-50%, which can positively affect inheritance tax. Whether you sell or rent your house, a thorough analysis of these points is essential for realistic pricing.

FAQ

How can I quickly and easily have an inherited house appraised?

For a quick initial assessment, you can use an online valuation tool like Auctoa ImmoGPT. For a legally sound valuation that is recognized by the tax office, you should hire a certified real estate expert and provide them with all necessary documents (land register extract, building plans, etc.).



Why is the tax office's valuation often higher than the market value?

The tax office uses standardized mass procedures and general data (e.g., land reference values) without an individual inspection of the property. Factors such as an undiscovered need for renovation, an unfavorable room layout, or noise pollution are not taken into account, which can lead to a systematically higher valuation.



Which documents are essential for the valuation of an inherited property?

The key documents are a current land register extract, an extract from the land map (site plan), building drawings (floor plans, sections, elevations), the calculation of living space, and the energy certificate. Evidence of recent modernisations is also very helpful.



Is capital gains tax always due when selling an inherited house?

No. Capital gains tax does not apply if the deceased acquired the property more than ten years ago or if they lived there themselves in the year of inheritance and the two previous years. These periods are transferred to the heir.



What if the community of heirs cannot agree on a value?

In this case, appointing a neutral, certified real estate expert is the best solution. Their market value report provides an objective and comprehensible basis for all parties, helping to avoid disputes and ensuring a fair payout to co-heirs.



How does the need for renovations affect the value of the inherited house?

A significant need for renovations, especially in energy-related areas (heating, insulation, windows), can considerably reduce the market value. Depending on the extent of the necessary work, the reduction in value can be 20-30% or more, as the buyer must consider these costs when determining their offer.
