Since the launch of Real Estate Principles: A Value Approach, significant and lasting changes have come upon the world of real estate. This is very true in real estate finance and capital sources where most of the traditional lenders have been transformed or displaced, giving way to a radically different set of players in mortgage finance. There has been change with profound and far-reaching implications in a world where it is understandable that property values can go down as well as up. This realization will color every aspect of real estate investment, finance and transactions for the foreseeable future.
