Monetization of qualitative impact factors

Abstract
For rental properties, the share of value-adding investments in building renovations is of major importance, as these costs may be passed on to the rental. However, the distinction between this and the share of building maintenance covered by the current rent is complex and can be a barrier to such refurbishment projects. Due to the lack of practical instruments, an alternative calculation method “BKP-Triage” was defined together with the clients SFOE & FOH (Federal Office for Housing) and in exchange with partners HEV Schweiz & Tenants' Association. The results of the 20 analyzed examples shows that the value-adding amount of refurbishments is in the range of 34 to 58 percent. The rate tends to be below the rate of cost transfer of 50 to 70 percent according to the VMWG. The developed toolbox provides a decision-making basis to evaluate the value-preserving and the value-adding part.
