Real(e)value uses WebGIS in real estate appraisal
“ WIGeoWeb is browser-based like our core product and meets the flexibility requirements we need to connect our IT solutions and optimize our process workflow.”
Jürgen Luhn, Managing Director Real(e)value
Real(e)value extends its proven real estate appraisal system with a spatial representation tool.
With their LIEBE system, the real estate appraisal service provider has been offering a high-performance product for years. By spatially analyzing the data with WIGeoWeb, relationships are now recognizable at a glance and the appraisal becomes even more accurate and valid.
Imagine that you have a house, apartment or land for sale and need a reliable estimate of the market value of your property. Would not it be practical if you could simply enter the key data on the location, size, age and condition of the object into an online tool and immediately received a sound and objective appraisal?
Real(e)value developed just such a tool and it has been successfully used throughout Austria since 2008. The companys target group includes banks, insurance companies, real estate agents and public authorities, in other words users who appraise real estate professionally. Since Real(e)value was founded, WIGeoGIS has been supporting them with software and data.
Purchase Price Benchmarking
The tool, which has the sweet-sounding name “LIEBE”, for Liegenschaftsbewertung, (LOVE - property valuation), achieves an accuracy of single digit percentage deviations from the future purchase price. This is made possible by the use of high-quality data and powerful mathematical models, that are scientifically recognized and are constantly reviewed by the Vienna University of Technology. The appraisals are based on the extensive in-house data sets collected by Real(e)value in previous appraisals, supplemented by available geo and sociodemographic data from third-party providers on population, purchasing power, topography, etc. One of the strengths of the tool is that the appraisal is not based on real estate broker offers, but on actual realized purchase prices.
Comprehensive support for experts
In order to provide real estate experts comprehensive support in the individual process steps of their appraisal, Real(e)value has created an entire set of tools to supplement the core product. For example, a walk-through app facilitates on-site inspections. The individual tools are technically integrated and connected in a user-friendly manner through suitable interfaces.
Quantum Leap through Spatial Representation
The most recent tool in this kit is a browser-based visualization tool that finds comparison objects in the surrounding area and presents them graphically on a map. The tool was realized with WIGeoWeb, the flexible WebGIS software from WIGeoGIS.
Jürgen Luhn, Managing Director of Real(e)value, explains a classic use case: “An appraiser has used the LIEBE tool to appraise the value of a five-year-old, 90 m2 condominium. With WIGeoWeb the appraiser can now view apartments of comparable size and age that were sold in the vicinity of the object.The exact catchment area can be drawn as a polygon on the map using the mouse.”
The apartments found, together with their corresponding values and key figures, are displayed directly on a map in the browser. A report is generated and an average is calculated. If it diverges significantly from the previously determined market value, the appraiser is required to correct it based on their experience and competence.“The expert can focus on their core competence, namely the review and confirmation or correction of the suggested value. Until now, we could only export the data as a list or table, which is too abstract in practice. Only with the help of spatial representation can we quickly draw the right conclusions”, said Luhn. For example, if an object is located very close to the apartment, but it is in a completely different district, this can be seen at a glance on the map.“That object would distort the purchase price and can be removed by the appraiser from the estimate. With the WIGeoWeb analysis, the expert can ensure the accuracy of their appraisal based on the LIEBE tool.”

“The system learns with each appraisal and thanks to the spatial combination of the data it provides analyses in a form unlike any other database in the world until now”, says Norbert Hackner-Jaklin, Key Account Manager at WIGeoGIS. “It clearly shows how with the help of WIGeoWeb we can make complex, unstructured data readable. We are not making a WebGIS for the real estate industry, as that would not be effective. Our software draws its strength and individuality from the respective customer data and can be applied across every industry.”
Easy to Use
The tool was rolled out in the first half of 2018. CEO Jürgen Luhn is satisfied with the progress of the project: “We have come to know WIGeoGIS over the past ten years as a reliable and competent partner. The combination of data provider and service provider is optimal for us. WIGeoWeb is browser-based like our LIEBE tool and meets exactly the flexibility requirements we need to connect our IT solutions with each other and to optimize our process workflow. We were also won over by the easy to use interface which is perfect for our wide circle of users.”
