Start from your situation. Every appraisal is prepared by certified experts – ordered online, at a fixed price.
Remaining useful life is how long a building can still be used economically. For a rental property, a certified appraisal can document a shorter period than the standard assumption. That may provide a basis for a higher annual AfA rate.
Landlords who believe their rental building may have a shorter useful life because of its age, condition or renovation history.

FAQ
Find answers to the most common questions about AfAMax, useful life appraisals, and using depreciation for tax purposes.
An appraisal is often worthwhile if you own a rented property and the actual remaining useful life is materially shorter than the standardized useful life. It is particularly relevant for buildings that are roughly 30+ years old and have neither undergone a full core refurbishment within the last 25 years nor a comprehensive modernization within the last 15 years. You can check your case upfront using our free preliminary assessment.
In principle, yes—provided the report is technically sound, plausible, and transparent. Following the German Federal Fiscal Court ruling of 28/07/2021 (case IX R 25/19), a shorter actual useful life can be applied when supported by an appropriate proof. Please note that laws, administrative practice, and case law can change over time; seek tax advice if needed.
Your appraisal is prepared by experts who are approved across Europe and certified in accordance with DIN EN ISO/IEC 17024. This is an important quality indicator and supports the report’s credibility and traceability.
As standard you receive your appraisal within 3–5 business days once we have all the information we need. The Express option is faster. If an on-site inspection is included, the appointment depends on local availability; missing documentation or follow-up questions can extend the timeline further.
Many tax offices expect an on-site inspection for remaining useful life evidence—or at least consider it a strong quality indicator. We recommend ordering the inspection upfront, as it helps document condition more robustly and often reduces follow-up questions.
In many cases, the appraisal fee can be deducted—typically as income-related expenses for rental income or as business expenses for business-use properties—because it relates to determining and optimizing depreciation. The exact treatment depends on your situation; consult your tax advisor if in doubt.
Where the contract contains an allocation, the tax office will accept it provided it is economically defensible and not merely nominal. In practice many contracts contain no allocation at all, and figures that depart sharply from the norm are regularly corrected. An allocation derived from the workbook gives you a defensible basis.
Both can determine the property’s market value using the recognised valuation methods under the ImmoWertV. The main difference is the scope of investigation and documentation. A Full Market Value Appraisal records the data, assumptions, methodology and supporting evidence in greater depth for situations where the result may be formally examined or contested. A Value Appraisal provides a professionally determined and explained market value in a shorter report for private decisions, planning and negotiations.
You can object to a tax notice within one month of its delivery (section 355 AO). The objection can be lodged first to meet the deadline and substantiated later. Send us your case as early as possible.

About AfAMax
AfAMax was created from real-world experience with a clear goal: to deliver tax-compliant, transparent and reliable valuation reports for property owners.
AfAMax is a brand of Rundum Immo UG and was developed jointly by real estate professionals and software experts. Our objective is to provide property owners with a clear and well-documented basis for tax depreciation – without unnecessary complexity. We work with certified expert appraisers (DIN EN ISO/IEC 17024) and combine professional depth with a structured, digital process. The result is valuation reports that are practical, audit-ready and suitable for tax purposes.
Managing Director · Real estate practice
Jannik Himmelsbach, Managing Director of Rundum Immo UG and Trivium Projektentwicklung GmbH, contributes many years of hands-on real estate experience. After completing a technical apprenticeship and making his own investments in residential property, he obtained IHK certifications as a real estate agent and property manager. He went on to found and successfully operate a property management company. Working closely with investors, existing buildings and renovation projects has given him a deep understanding of how buildings age, how refurbishments impact value, and where standardised assumptions fail to reflect reality – this is exactly where AfAMax adds value.
Managing Director · Product & technology
Manfred Mayer-Rieger, Managing Director of pragtex GmbH and Rundum Immo UG, is a software developer by passion with long-standing involvement in real estate and ownership of older residential properties. Driven by personal experience, he set out to make complex tax-related topics transparent, understandable and user-friendly. At AfAMax, he is responsible for the digital process design, user experience and technical quality – ensuring that property owners quickly understand their situation and can make well-founded decisions.
Client advisory & sales
Maya Diehl is studying dentistry and, alongside her studies, developed a particular interest in the real estate sector. Through close collaboration with property owners and appraisers as well as supporting remaining useful life reports, she gained comprehensive insights into the tax-related and economic potential of real estate. At AfAMax, she is responsible for client advisory, sales and social media.
Statutory auditor · Report quality
Björn von Olnhausen is a statutory auditor who advises family businesses and their shareholders. His areas of focus include statutory audits, business valuations and due diligence reviews – assignments that require precise judgment and careful documentation. At AfAMax, he applies this experience to supporting remaining useful life cases. He helps prepare documents and valuation inputs in a clear, traceable way and develop well-founded responses to technical queries from the tax office. His auditing perspective thus strengthens the remaining useful life case beyond the preparation of the appraisal report.
