If another standard (partial value, Earned value, derivative value standards), the common value is to be taken as the basis of the valuation as the original assessment standard. In contrast to the overall evaluation of the partial value, an isolated evaluation of individual assets takes place in the case of the common value.
The scope of application is essentially limited to the valuation of real estate and, in connection with the dormant wealth tax, to other assets. According to § 9 BewG, it is the price (including value added tax) that would be achieved in trading on the free market when selling the respective asset under normal circumstances. Unusual circumstances and circumstances influencing prices must be taken into account, but not personal circumstances.
The common value thus represents the fictitious individual selling price from the point of view of the seller. If there is no market price, the value can be derived from a large number of sales. The valuation can also be based on general values based on the purchase or purchase price Manufacturing costs orientate or take place through the capitalization of income.
