Iv'e read a lot of commercial real estate books on my way to my career as a broker associate in this field. Usually the information is so dry and based on “old school” information and methodology. These are proven methodologies of evaluating investment properties that he and his contemporaries developed over decades of experience but it’s incredibly relevant to anyone from investors, brokers, lenders, and even students.
This is a book I’ll be referencing daily on my desk as I work with clients- both buyers and sellers.
I’ll be purchasing more copies for colleagues and new investors. If they adhere to the Big Six Formula they will increase their net worth exponentially, no matter the role they have in income producing properties.
