When Do You Need a Property Valuation?
A property valuation is particularly important in five situations: before selling, to establish the right asking price and negotiate with confidence; in divorce proceedings, to legally calculate the matrimonial property equalisation (Zugewinnausgleich); when inheriting property, to correctly handle inheritance tax and estate division; for tax purposes, especially following the German property tax reform of 2025; and in mortgage financing, where banks require a recognised mortgage lending value (Beleihungswert) before approving a loan.
Property Valuation When Selling
Before selling a property, an independent valuation is the most important tool for determining the right asking price. Setting the price too high leaves the property on the market and signals problems to potential buyers; setting it too low gives away capital that may have been tied up for decades.
According to ImmoScout24's market report Q1 2026, properties listed more than 15 percent above the market average remain on the market an average of 68 days longer and ultimately sell at a discount of 10 to 20 percent. A well-founded valuation gives sellers credible arguments in negotiations with agents and buyers, prevents emotionally driven mispricing, and accelerates the sale process. It also forms the basis for a pricing strategy: listing just below a psychological price threshold or offering with a modest negotiation buffer.
Property Valuation in Divorce
In divorce proceedings in Germany, a recognised property valuation is legally necessary to correctly calculate the matrimonial property equalisation (Zugewinnausgleich) under Section 1375 of the German Civil Code (BGB). The market value of jointly owned property must be determined as of the date the divorce petition is served.
If the parties cannot agree, the family court orders an expert appraisal, the costs of which are shared equally between both parties. A report produced by a recognised valuer is binding on the court and cannot be replaced by an online valuation. According to the Federal Statistical Office (Destatis) 2024, approximately 70 percent of the around 130,000 divorces in Germany involved jointly owned property. In addition to the matrimonial equalisation, it must be established whether one party will acquire the property at the assessed value or whether a court-ordered auction (Teilungsversteigerung) is required.
Property Valuation in Inheritance
When a property is inherited, the German tax authority (Finanzamt) initially determines the taxable value using standardised procedures based on the standard land value (Bodenrichtwert). If this assessed value exceeds the actual market value, heirs may commission an independent expert to limit the tax burden to the legally correct amount.
The Inheritance and Gift Tax Act (Erbschaftsteuer- und Schenkungsteuergesetz, ErbStG) explicitly provides in Section 198 that a lower market value may be substituted for the assessed value if evidenced by an expert appraisal. With a tax-free allowance of EUR 400,000 for children and a tax rate of 11 to 30 percent, a EUR 50,000 lower assessed value can reduce the tax burden by EUR 5,500 to EUR 15,000. According to a ruling by the Federal Finance Court (Bundesfinanzhof), the appraisal is effective when produced by a valuer certified under DIN EN ISO/IEC 17024. In joint inheritances (Erbengemeinschaft), the valuation also forms the basis for the estate distribution: any heir who wishes to acquire the property must pay the other heirs their proportionate share of the market value.
Property Valuation for Tax Purposes
Since the German property tax reform, effective in all federal states from 2025, land and buildings have been re-assessed for property tax purposes. Property owners have the right to substitute a proven lower market value if the tax value determined by the Finanzamt exceeds the actual market value.
Beyond property tax, valuations also play a central role in gift tax when properties are transferred during the owner's lifetime. In these cases, the Finanzamt applies the comparative or income method under the Valuation Act (Bewertungsgesetz, BewG). According to an analysis by the German Taxpayers' Association (Deutscher Steuerzahlerbund) 2025, in approximately 25 percent of cases the tax authority's automatically assessed property tax value exceeds the actual market value by more than ten percent, making a formal objection economically worthwhile. An independent expert appraisal is the most reliable evidence in such proceedings.
Property Valuation for Mortgage Financing
Banks and lenders are legally required to determine a mortgage lending value (Beleihungswert) before granting a loan — a value representing the long-term, sustainable worth of the property. This lending value is typically 10 to 30 percent below the current market value.
The lending value assessment is governed by the Mortgage Lending Value Regulation (Beleihungswertermittlungsverordnung, BelWertV) and must be carried out by internal or accredited external valuers. The loan-to-value ratio — the relationship between the loan amount and the lending value — is a key determinant of the interest rate. According to the Deutsche Bundesbank 2025, banks offer their best rates for loan-to-value ratios below 60 percent; above 80 percent, surcharges of 0.3 to 0.8 percentage points apply. Anyone planning a mortgage renewal or wishing to use a partially paid-off property as collateral benefits from an up-to-date valuation that documents the property's increased value and reduces the loan-to-value ratio.
Frequently Asked Questions
Do I need a formal appraisal or is an online valuation sufficient?
For initial orientation — for example to decide whether selling makes financial sense — an algorithm-based online valuation like HalloSara is sufficient. For legally binding purposes such as divorce settlements, inheritance tax, mortgage financing, or court proceedings, a certified expert appraisal is required.
What does a certified expert appraisal cost?
Costs depend on the property value and complexity. For a property worth EUR 300,000, a full appraisal typically costs EUR 900 to EUR 1,500; for EUR 600,000, between EUR 1,400 and EUR 2,500. Short-form reports or valuation statements (without a physical inspection) are available from around EUR 400, but are not always accepted by courts and banks.
How long does a professional property valuation take?
A full market value appraisal typically takes two to four weeks from the initial consultation to delivery of the final report. This includes approximately one week for scheduling and inspection and one to three weeks for preparation. Rush appraisals can be completed in one week, but are usually more expensive.
When will the tax authority not accept an online valuation?
The tax authority (Finanzamt) does not accept online valuations for determining inheritance or gift tax. Only an appraisal by a publicly appointed expert or a valuer certified under DIN EN ISO/IEC 17024 is recognised as evidence of a lower market value. This also applies to objections against assessed property tax values.
Can I estimate the value of my property myself?
As a basis for personal decisions, property owners can estimate value using online tools or by comparing current listings. This is not sufficient for negotiations, legal proceedings, or bank discussions. Independent valuations by certified experts or reliable online services like HalloSara provide a more objective foundation.
