Must Have Book for Investors or Sponsors/GPs wanting to Invest in Multifamily Properties!
Format: Paperback
If you understand the math and numbers associated with investing in real estate, this book will help you underwrite any multifamily property. Not only does Robert's book discuss how to gather the information needed for underwriting, he goes into detail on how sponsors can manipulate the numbers. This is a great book for knowledge on the pros and cons of varied partnership structures and how each can create an alignment of interest between limited partners (LPs) and general partners (GPs). Overall, this is a great easy read book.

Basic knowledge of underwriting is necessary to understand.
Format: Paperback
This is a great guide for underwriting multifamily deals for someone with some basic to moderate knowledge of underwriting. I am a new student to this field and have to stop and google some of the acronyms. For a future version, I think adding an extra page for the acronyms used, definition and equation would be helpful. I think that the font could be larger and darker. Adding mathematical formulas in the book would provide visualization as well. Rob can also provide a sample OM for the reader to use with his underwriting model and compare to his completed one. Again, I am a newbie so my review may change as I gain knowledge in this area. I enjoyed listening to Rob on Youtube/Podcast and hope to learn more from him.

great read for underwriters of multifamily deals
Format: Kindle
Rob lays out a succinct and thorough summary of his underwriting process, questions industry standards while sharing his opinions, and discusses risk management and analyses for deals during the underwriting process. Highly recommend for newer and more seasoned underwriters and investors to build or sharpen multifamily underwriting fundamentals and details. He also shares his model as the example.
