Real estate investments are becoming ever more influenced by supervisory regulation. The financial risks associated with properties must be assessed and monitored.

RIWIS data is based on continuous and objective market observation and thus offers the ideal foundation to support the processes of monitoring, risk minimisation, audit compliance and also transparency. Supervisory requirements can be properly met and the application of regulations such as Basel III, MaRisk, KWG 20, BelWertV, SolvV, Solvency II, ImmoWertV, ErbStRG, or WertR2006 is fully supported.

Asset Check

The Asset Check enables a fast, well-founded and independent audit of the economic efficiency. The digital quick analysis tool is suitable for various types of commercial real estate – nationwide.


Usage-specific benchmarks help Asset Check users to accelerate their response and decision-making phases.

The tool provides a complete digital object and market data based benchmarking and thus a quick pre-valuation of real estate during the phases purchase, hold and sale. The user receives information on income and costs and thus for the first time all important investment information from a single source.

The Asset Check was created in cooperation with Drees & Sommer. In each Asset Check, the property-specific data is compared with real estate market data from RIWIS as well as with Drees & Sommer construction technology benchmarks.

Target Group

Inventory holders, investors, real estate consultants, project developers and asset managers.

How it works – the actual Asset Check

The Asset Check provides information about the exact location of the property, general market information as well as income and cost situations.
For example, the Asset Check determines the possible rental margins of the location based on the location and asset type. If the revenues of the respective use and any vacancies have been stated, the information such as income or rent losses is calculated on the dimensions of the respective asset. Operating and maintenance costs are determined on the basis of object properties such as age or standard of completion and can thus already be compared with earnings at this early stage.

All Asset Checks work interactively and prepare the relevant results in a meaningful way. All registered and created objects are only available to the registered user.
