Oliver Everling and Raphael Slowik (Editor): Practical Guide to Ratings of Real Estate Portfolios, Immobilien Manager Verlag, Cologne, http://www.immobilienmanager.de/, bound edition, 1st edition 2009, 456 pages, ISBN 978-3-89984-197-8.
The book is in the German-speaking world and probably also internationally the first book for the rating of real estate portfolios. Since real estate is increasingly being actively managed by companies, (regional) corporations and foundations as an own asset class, it depends on the valuation and assessment standards that affect both the individual property / project and the portfolio as a whole.
The approaches that have been developed to this end, despite the growing interest of investors, who have to form judgments under more and more direct and indirect variants of the real estate investment, have so far been little known. The book shows the most important procedures and systems of the rating and aims in particular at the business management and legal design possibilities of real estate transactions for the optimization of real estate portfolios. The book sets standards in relation to the relevant questions and starting points.
