The valuation of such properties poses a particular challenge and should therefore remain the job for experts with specialist knowledge of agriculture and forestry. A whole number of special laws (lex specialis) apply to areas used for agriculture and forestry. Knowledge of these laws and the relevant case law is an indispensable requirement for the appraiser.

The allocation of a certain pecuniary value for the individual assets (such as land value, building value, the value of outdoor facilities, inventory value) is only part of the matter, but how we deal with the results as experts is the essential factor of our work. Not only are the particular features of each individual property to be valuated but also its environment must be considered in many respects and the results presented in a coherent and comprehensible manner.

Both agriculture and forestry are subject to a constant process of change. As an example of this, we should mention the increasingly important adaptation of forests and agricultural crops to climate change, which constitutes a significant risk factor for each individual farm. This process also has to find its way into property valuation as a dynamic system in individual cases.
