Complexities of Property Valuation Highlighted by BLUMENAUER Immobilien

BLUMENAUER Immobilien, a German real estate firm with decades of experience, has issued a press release emphasizing the complexity of property valuation. The company argues that the market value of a property is not a simple calculation, despite the advancements in digitalization and artificial intelligence (AI) that have transformed real estate valuation.

According to the release, online portals and professional software can provide quick estimates of property values. However, these tools can create a false sense of accuracy. Numbers with two decimal places may suggest precision, but the market value of a property is inherently approximate. Even AI, which can analyze large datasets, cannot guarantee absolute accuracy if the input data is incomplete or outdated.

The release highlights that factors such as lot size, living area, year of construction, amenities, comparable prices, and construction costs are crucial but not definitive. Standard land values, which are used to categorize properties, can also be misleading. Properties within the same standard land value zone can have vastly different characteristics, such as views, sunlight, noise, privacy, and layout. For instance, a property with a garden and terrace may border a heavily trafficked main road, while a similar property just a few meters away offers a quieter setting.

Moreover, the release points out that individuality plays a significant role in property valuation. People's preferences and emotional connections to a property can greatly influence its market value. For example, a large yard may be a deal-breaker for one buyer and the reason another decides to purchase. Similarly, proximity to a school may be advantageous for one family and a disadvantage for another. These factors, which cannot be fully captured in tables or algorithms, are crucial in determining a property's true value.

The press release also notes that sellers' circumstances, such as the timing of the sale, asking price, willingness to negotiate, and personal circumstances, can significantly impact the transaction. Therefore, a valuation report should not be the sole criterion for selling a property. Instead, it should be used as a valuable guide alongside on-site assessments and the experience of seeing how prospective buyers react to the specific property.

BLUMENAUER Immobilien stresses the importance of expert appraisals, especially in legal proceedings, inheritance disputes, divorces, tax matters, and financing. However, the company warns against equating an appraised value with a guaranteed achievable sales price. A discrepancy between an appraisal and a later sales price does not necessarily indicate a mistake by the appraiser. Similarly, a formally correct appraisal does not guarantee that the stated value can be realized in the market.

The release concludes by emphasizing that while data, appraisals, and AI can provide valuable insights, they do not replace the experience of seeing how prospective buyers react to a specific property. In the end, a property is purchased by a person, not by software. The future of real estate valuation lies in recognizing the unique nature of properties and people, rather than assuming that technology can fully calculate a property's value.

The release was published on openPR on July 28, 2026, in Neu-Anspach, Germany. It mentions the official donation of a nearly complete collection of Otto mail-order catalogs from 1952 to 2019 by real estate expert Harald Blumenauer, which the Hessenpark Open-Air Museum received as a significant new addition to its collections. The release also notes that the average household size was 4.6 people in 1871, the structure of households has changed fundamentally, with more than one in five households consisting of a single person today.
