The influence of immovable resources on the achievement of corporate goals, is increasingly recognized by corporates. As a result, improving the efficiency of real estate management is becoming more and more important. Due to the major leverage regarding costs and benefits, in particular the procurement of new real estate is very important. For this purpose are two variants available. Firstly the corporates are solely responsible for the investment or secondly buy the investment performance on the market via an investor model. In addition to these two variants, the PPP concept has been succesfully established in recent years. However, this partnership model has not been transferred to the procurement of corporate real estate till yet. This paper analyzes on the one hand the structural and procedural characteristics of the three procurement variants. On the other hand, are those criteria presented which are relevant from the perspective of the corporates to increase efficiency in the procurement of real estate. In the empirical part of the paper are three case studies of the procurement variants in terms of meeting the efficiency criteria compared. This comparison is based on data which were generated in the scientific monitoring of a pilot project. In this pilot project the PPP concept is transferred to private real estate users for the first time. The determination of the efficiency differences is carried out by using the TOPSIS technique. This technique makes it possible to measure the relative efficiency of the different variants among themselves, without having a fixed standard of comparison. To increase the efficiency of the transmission the PPP concept to corporate real estate, concrete recommendations are developed from the findings of the efficiency analysis.
