Every property has its price. We determine its value.


Premises, houses, or flats. Retail industry, offices, or hotels. We assess the value of any kind of properties. On the one hand, we render expert opinions as a secure and objective appraisal of the current market value that can also be used for legal purposes. On the other hand, we determine mortgage lending values as a loan collateral for credit institutions. Common reasons for the preparations of an expert opinion are purchases and sales of properties, inheritances, divorces, or when required by the tax office. If desired, we also validate the plausibility of existing valuation reports. In case you do not necessarily need a comprehensive opinion of experts for your property, we also offer value indications.


As independent, experienced surveyors we provide our business and private customers with professional advice regarding their properties. For each individual concern we develop a suitable solution approach. When realising a so-called SWOT analysis, we prepare all decision-relevant data and facts to point out the strengths, weaknesses, chances, and risks of the property concerned. From these concrete advantages and disadvantages, we can derive strategic options for action, allowing you to take an informed decision. A SWOT analysis can be realised internally, relating to the property itself, or externally, e.g. with reference to the developments of the property’s immediate environment or relating to the real-estate market.
