Standard land value vs. market value: What investors really need to know about real estate
Wer Immobilien nicht zum Wohnen, sondern als Kapitalanlage betrachtet, stößt früher oder später auf zwei Begriffe, die im Alltag oft synonym verwendet werden, rechtlich und wirtschaftlich aber vollkommen unterschiedliche Funktionen erfüllen: den Bodenrichtwert und den Verkehrswert. Für die Ankaufsprüfung, die Finanzierungsstruktur und nicht zuletzt für die steuerliche Behandlung einer Immobilie – etwa wenn bei der Erbschaftssteuer der Verkehrswert als Bemessungsgrundlage herangezogen wird – ist die Unterscheidung keine akademische Feinheit, sondern eine Grundlage für belastbare Investitionsentscheidungen. Gerade weil beide Werte häufig aus denselben amtlichen Quellen stammen oder in Exposés nebeneinander auftauchen, entsteht in der Praxis oft der Eindruck, es handle sich um zwei alternative Schätzungen desselben Sachverhalts. Tatsächlich beantworten sie aber grundsätzlich verschiedene Fragen: Der eine liefert eine standardisierte Referenzgröße für den Boden, der andere den individuellen Preis eines konkreten Objekts zu einem bestimmten Zeitpunkt – eine Größe, die Investoren auch beim Kaufpreisfaktor im Vergleich zur Mietrendite im Blick behalten sollten.
The Land Value: Legal Basis and Calculation Logic
The land value is an average location value for unbuilt land within a defined land value zone. Legally, it is anchored in § 196 BauGB, according to which the expert committees of the municipalities and districts determine land values on a comprehensive basis using the actual purchase prices from the respective price collection. The values are updated annually or at least every two years on a fixed cut-off date and made publicly accessible through the BORIS portals (land value information systems) of the federal states.
The Land Value Plot as a Reference Size
Important for practice: The land value refers not to a real, but to a fictional reference plot with average characteristics, the so-called land value plot. Which plot characteristics may be taken into account and which individual peculiarities are explicitly excluded is regulated by § 16 ImmoWertV. Exactly at this point, the deviation from the market value described later arises: A specific plot can deviate significantly from the reference plot in terms of plot size, state of development, contamination situation, or buildability, without this being reflected in the land value itself.
Regional Dispersion within Individual Land Value Zones
In practice, it is also noticeable that land value zones are sometimes quite large in area and considerable differences in location quality can exist within a zone, for example, between a main traffic artery and a quiet side street in the same district. In such cases, the expert committee calculates an average zone value, which can be significantly too high or too low for a plot at the edge of the zone. For investors, this means that the land value should always be read in the context of the zone boundaries and not as a precise value for a specific address.
The Market Value: The Actual Market Value of a Specific Property
In contrast, the market value (also known as the market price) is defined in § 194 BauGB as the price that could be achieved in the usual business dealings, taking into account the legal circumstances, actual properties, other conditions, and location of the plot, without regard to unusual or personal circumstances at a certain point in time. It therefore always refers to a specific, individual object and not to a statistical reference plot.
An Overview of the Three Valuation Methods
According to the Ordinance on the Valuation of Real Estate, there are three methods available for determining the market value, the choice of which largely depends on the type of property:
- Comparison Method: Derivation from actual purchase prices of comparable properties, primarily used for owner-occupied apartments and unbuilt plots.
- Income Method: Capitalization of the sustainable rental income minus operating costs and land rent, the standard method for rented income-generating properties and commercial real estate.
- Cost Method: Determination by adding the land value and the construction costs of the building minus the depreciation due to age, especially for owner-occupied properties without a meaningful rental market.
For investors, the income method is usually decisive, as it directly incorporates the actual or market rental rate into the valuation and thus reflects the return logic of the investment.
Alongside the three classic methods, there are object-specific special factors that cannot be represented in the land value or in a general market analysis, but must be considered separately in the income or cost method. These include, for example, an existing building right, encumbrances such as a usufruct, heritage protection requirements, or known contamination on the plot. Such peculiarities can significantly shift the market value of an object compared to a comparable, unencumbered plot in the same land value zone, without this being apparent from the official land value.
Land Value vs. Market Value: The Central Differences in Comparison
| Criterion | Land Value | Market Value |
|---|---|---|
| Legal basis | § 196 BauGB | § 194 BauGB |
| Reference object | Fictitious land value reference plot | Concrete, individual plot/building |
| Determined by | Valuation committee (official) | Appraiser, expert, market participant |
| Update | Annually up to every 2 years, reference date | Event-based, precise in time |
| Considers development | No, pure land value | Yes, including building value and yield situation |
| Typical use | Plausibility check, land tax, need value | Purchase price check, financing, sale, accounting |
| Example calculation (200 sqm plot) | Land value 450 EUR/sqm = 90,000 EUR pure land value | Market value of renovated multi-family house approx. 640,000 EUR (income approach) |
The calculation example in the last line is intentionally meant as a calculation example: It shows how much the pure land value and the actual market value achievable for a developed, rented property can differ once building substance, rental income, and modernization level are included in the evaluation.
Why the difference is strategically relevant for investors
For investors, the clear separation of both figures is specifically beneficial: Land value and market value answer different questions in the investment process and are therefore relevant at different points in the evaluation – from the first market check to the bank’s financing approval.
Land value as an early indicator and plausibility check
For the first assessment of a market or district, the land value is a useful, freely accessible tool: If the land value of a zone increases significantly more over several updating cycles than the citywide average, this indicates a beginning increase in the surrounding area, even before this is fully reflected in the offer prices. For placing such location developments in the overall German market context, the Federal Statistical Office with the House Price Index regularly provides official comparative data on nationwide price developments, against which local land value movements can be assessed. However, a sole conclusion from the land value to the achievable purchase price of a specific object is not permissible, as individual value factors are missing.
Pitfalls with yield objects
With rented multi-family houses and commercial units, the market value regularly deviates most strongly from the pure land value, because rental contract structure, remaining lease terms, indexing clauses, and the backlog of building maintenance directly influence the income approach. Two objects on the same building block with the same land value can therefore show a deviation of 30 percent or more in market value, depending on whether existing rents are significantly below or close to the local comparable rent. This risk becomes particularly clear when vacancy and rent defaults significantly reduce the income of an object, because then the market value decreases independently of the unchanged land value of the area. Another factor, often underestimated in practice, is the property interest rate, with which the valuation committees discount the capitalized income: Even slight deviations in the assumed interest rate can lead to noticeable differences in the calculated income value for long-term existing properties, which is why investors should always critically examine the initial parameters used in an appraisal.
Land value and loan value in real estate financing
The land value also plays a role on the financing side, although indirectly: Banks usually determine their own, conservatively calculated loan value for granting credit, which incorporates structural and conjunctural risks according to the loan value assessment regulation and therefore regularly lies below the market value. The land value serves here as one of several plausibility factors, but it does not replace the internal bank appraisal or the loan value assessment. Anyone who wants to calculate in advance how much credit is realistically financable based on their own budget should use this more conservative loan value and not the more optimistic market value as the calculation basis. For the financing structure of an investment, this means: Those who calculate solely based on the land value usually overestimate the loanable portion of the purchase price.
Tax implications: Land tax and need value
For the upcoming basic tax reform applicable from 2025 and for the need-based valuation of inheritance and gift taxes, tax authorities in many cases rely on land price indices as a simplified, standardized basis for assessment. This means for investors: The tax valuation of a property can deviate significantly from the actual market value achievable on the market. Where the typified tax valuation is above the realistic market value, an individual market value assessment opens the possibility of providing so-called proof of lower valuation to the tax office.
Checklist for Purchase Verification
For the practical due diligence of a real estate investment, the insights into land price indices and market value can be summarized in a few checks, in addition to a general risk checklist for capital investments:
- Retrieve the land price index of the zone via the responsible BORIS portal and check the zone boundaries for differences in location quality.
- Compare the historical development of the land price index over several reference dates to assess market dynamics.
- For rented properties, verify the income value method, particularly remaining lease terms and the assumed property interest rate.
- Do not equate the bank’s loan value with the market value, but calculate them separately.
- For larger investments, obtain an independent market value assessment, especially if tax-based need values deviate significantly from the estimated market value.
Conclusion: Two Indicators, Two Different Functions
The land price index is an official, standardized tool for the comprehensive valuation of land and property and is suitable for market assessments, early indicators, and typified tax procedures. The market value, on the other hand, reflects the actual, individual market value of a specific property and is therefore the key figure for purchase, financing, and exit decisions. For a reliable investment decision, capital investors should know both values, but never exchange them: The land price index provides the context, the market value provides the price.
