Hey @Account Closed,
I have read a couple of books that I really enjoyed. "Commercial Mortgages 101" by Michael Reinhard, "Long-Distance Real Estate Investing" by Daivd Greene, and "The Millionaire Real Estate Investor" by Gary Keller.
"Millionaire Real Estate Investor": reads as some what of a self-help book (in a good way) with detailed steps of how to build a criteria, what to look for. It also has a collection of models, strategies, and testimonials from other investors.
"Long-Distance Real Estate Investing": A very detailed book with precise steps to take towards making a RE investment, albeit out-of-state. Majority of the information provided in this book may be applied to local RE investments as well.
"Commercial Mortgages 101": Provides a different perspective from what lenders look for. Gives great breakdowns of various metrics to look at to make a much more safe and sound investment. The book's target audience is certainly mortgage brokers and or RE investors who are looking a larger commercial properties. However, I think it is a must read.
