Real Estate

3.0From consulting to valuation

We are your reliable partner for true-to-market, well-founded analyses, appraisals, and evaluations of real estate. As qualified and certified appraisers, we advise you on properties of all asset classes – developed or undeveloped land, residential, commercial, or special real estate – providing clarity and transparency in decision-making.

3.1Our range of services

Individual valuation for all types of property

Residential real estate from condominiums to residential complexes // Commercial real estate from offices to shopping centers and logistics facilities // Operator real estate from hotels to care facilities // Educational facilities such as kindergartens, day care centers, and schools // Special real estate such as hospitals, sports facilities, or amusement parks

Market and mortgage lending value appraisals

We prepare market and mortgage lending value appraisals for all types of real estate based on recognized and standardized procedures.

Market value appraisals

We prepare all market value appraisals independently, free of directives, conscientiously, individually, and unbiased to the best of our knowledge and belief.


Real estate portfolio valuations are called for on a variety of occasions. These include, for example, portfolio transactions when selling real estate or shares of the real estate portfolio, financing, accounting, or securitization.

Remaining useful life appraisals

We determine the actual remaining useful life of your property, which serves as the basis for the tax depreciation for wear and tear of the building. Particularly in the case of older, unrenovated buildings, the effective remaining useful life is often significantly lower than the standard set by the legislator. With the appraisal prepared by us as certified experts in accordance with DIN EN ISO/IEC 17024, you receive a document recognized by the tax authorities that shows the actual remaining useful life and thus makes tax benefits realizable.

Value indications

A value indication is a written estimate of a property’s value based on information provided by the client and a site inspection.

Value audits and value updates

In the credit process, further tasks such as value audits and value updates arise in addition to the preparation of value appraisals. We provide you with nationwide support based on our high level of expertise.

Construction Status Reports

A construction progress report is a report on the status of work in the construction of a building. It presents the percentage of completion of the shell, finishes, and exterior, as well as any complaints and the value of the construction completed to date.

Economic analyses of the real estate sector

We make market data transparent and provide a well-founded basis for decision-making by conducting analyses of the situation in the construction industry and studies of the German real estate market.

Site, property, and object analyses

We conduct a detailed site and property analysis to assess the infrastructure of the site and the properties.

Portfolio structuring

Investment strategies must be continuously adjusted to the changing conditions of the time. Portfolio structuring is an investment strategy in which investments in a portfolio are distributed to achieve the highest possible profit while minimizing risk.

Valuation of all asset classes

Asset classes is a term used in the real estate industry to distinguish between the construction, use, and quality of different properties. These include so-called superordinate asset classes such as residential real estate, commercial real estate, and special real estate, subdivided into several subclasses.
