The property value market adjustment factor represents the average ratio (or a mediating function) from purchase prices and corresponding to them, pursuant to the provisions of the ImmoWertV determined (provisional) property values . This is quasi by multiple "counter reviews" of selling objects using property value model of ImmoWertV derived .

The provisional material value of a built-up property is the sum of the land value, the building value and the value of the outdoor facilities. This is a computationally determined value based primarily on considerations of substance value. The real value method only experiences the necessary market reference through the use of the real value market adjustment factor derived from the property type.

Today, many expert committees across Germany derive real value market adjustment factors for different types of property in uniform and differentiated models as part of the purchase price collection, such as the property interest rate using the discounted earnings method. Only by using these factors is it possible to use the real value method of ImmoWertV to determine real estate values ​​in line with the market.

The real value method is basically based on the intrinsic value of the built-up property, which is derived from the substance. However, this does not mean that a third party is also willing to pay a corresponding price for it. In this respect, the real asset market adjustment factor represents an economic demand curve in the survey area of ​​the respective expert committee, which depicts the average buyer behavior for a certain property size. Experience has shown that there are corresponding discounts for relatively high material values, and surcharges for properties with low material values. In addition, reference should be made to the restrictions on the type of property to be valued using the material value method, as set out in the article on real value . As with the property interest rate, a sufficient number of comparative cases in the survey area is necessary for a reliable derivation.
