It formulates research questions, motivates the need for more consistent valuation approaches, and documents the contributions of co-authored submissions and academic dissemination. Using structured datasets and clearly defined modeling components, it presents expert functions, baseline and advanced algorithms such as OLS, GAM, and XGBoost, and a testing framework. Evaluation focuses on suitable performance metrics and practical implications for property appraisal workflows.","Real Estate Valuation  \nin the Age of Artificial Intelligence – Modern Machine Learning Algorithms and their Application in Property Appraisal  \nA dissertation presented for the degree of“Doktor der Wirtschaftswissenschaften”  \n[Dr. rer. pol.]  \nSubmitted to the Faculty of Business, Economics, and Management Information Systems at the University of Regensburg  \nby  \nMORITZ STANG  \nM.Sc.

Therefore, I would like to take the opportunity to express my gratitude to these individuals.  \nFirst and foremost, I would like to express my appreciation to my supervisor, Prof. Dr. Wolfgang Schäfers. I thank him for his unwavering support, the inspiring discussions and the ongoing opportunities for growth and development during the last years. The collaboration with him has been immensely beneficial both academically and personally for me. Additionally, I would like to thank Prof. Dr. Tobias Just for his support, valuable comments, and taking over as secondary supervisor.  \nNext, I would like to thank my co-authors Bastian Krämer, Dr. Cathrine Nagl, Prof. Dr. Wolfgang Schäfers, and PD Dr. Marcelo Cajias. Without them, completing and publishing the individual papers would not have been possible. In particular, I would like to express my sincere gratitude to Bastian Krämer for his valuable contribution to the completion of this dissertation. His scientific and personal intellect has greatly assisted me throughout this journey. I will always cherish the hours-long working sessions and extensive discussions we had together.  \nA special thanks also goes to my colleagues at the IRE| BS Institute, especially Bastian Krämer, Daniel Promper, Benedict von Ahlefeldt-Dehn, Nino Paulus, Jürgen Deppner, and Dr. Cathrine Nagl. Each and every one of you has shown me over the past three years what it means to work in an ambitious team. Not only professionally, but also personally, you have helped me greatly, for which I am very grateful.  \nFrom the bottom of my heart, I also want to thank my family and friends for their support. Specifically, I would like to thank my father Dr. Joachim Stang, my mother Birgit Schabesberger-Stang, and my sister Marlene Stang. Not only during the period of my dissertation, but also since my birth, I can always count on your support. I am grateful foryour relentless guidance, which has played an integral role in shaping me into the person Iam today. Thank you for always being there for me.  \nLast but not least, I would like to express my heartfelt gratitude to the partner by my side, Verena Lehner. Dear Verena, words cannot express how grateful I am for all your support and love. Without you, the past years would have been only half as fulfilling and worthwhile. I look forward to a joint future with you! The world belongs to both of us and the rest of our family!  \nTable of Contents  \nList of Tables ...............................................................................................................
