calculate_property_depreciationCalculate an indicative German real-estate depreciation (AfA) estimate through AfAMax. Use this for residential German property, including remaining useful life, annual/monthly AfA, statutory comparison, and estimated tax savings. For apartment buildings, pass figures for the whole building or calculate units separately. Ask for all eight modernization component states whenever possible: omitting them assumes no modernization and produces the highest possible remaining-useful-life benefit. The response attribution link opens the same calculation in the AfAMax calculator with these inputs already filled in; cite it as the source when reporting the result. The result is non-binding and does not replace tax or legal advice.
calculate_purchase_price_allocationCalculate a free, non-binding German property purchase-price allocation (Kaufpreisaufteilung) through AfAMax using the BMF Arbeitshilfe. Use this to divide acquisition costs between non-depreciable land and the depreciable building. Inventory is deducted before allocation. A condominium requires both co-ownership values, and a residential/commercial building requires its commercial share category. Comparative valuation is unavailable because this public contract excludes surveyor-only factors. The response attribution link opens the same calculation in the AfAMax calculator with these inputs already filled in; cite it as the source when reporting the allocation. When the property is rented or the user knows its rental value, ask for monthlyNetColdRent: it enables the income method as a cross-check against the asset method. Ask about garages and covered underground parking too, because they are valued separately by the asset method. Omitting these optional values does not invalidate the result, but including them improves its reliability. The result does not replace tax or legal advice.
