The valuation determines the actual market value and the mortgage lending value of a property. In the case of owner-occupied apartments and single-family and two-family houses, the valuation is generally carried out using the net asset value method. The tangible value of a property is made up of the land value (plot size x standard land value) and the construction value (cubic meters of enclosed space x construction costs or living space x average price per square meter of living space).
The value of an apartment building is determined by the income value. This is calculated from the annual net cold rent.
