An appraisal or a valuation?

If you want to know the value of a real estate object or a development, you will have to determine the value of this. Is a project easily lettable, or are additional investments required for a good business case. As an investor of real estate you need a well-founded understanding of the potential value of a new investment and the required financial resources for now and in the future. This can be done by means of a taxation or a valuation. An appraisal report is a comprehensive report in which, in addition to the values, the public and private law aspects and the structural condition of the collateral are highlighted. A taxtation is therefore often done with existing real estate. A valuation is a calculation of the value based on assumptions at an early stage of the process, you do this by working out different scenarios with, for example, further exploitation in current site requirements, small or full transformations, extensions or even demolition-new construction. You have come to the right place for the reports at IGG.
