There are many quality courses out there that could help you achieve lasting success. Be wary of courses that have endless “up-sells” with boot camps, personal coaching, and more detailed courses on the same material. Don’t buy hype and seminars. A true real estate course should be a complete guide from start to finish so that you can complete the type of investment you are trying to accomplish without the need for additional information.
Admittedly, we are clearly biased on the subject, but I would have you check out Matthew David’s Short Sale Mastery, Matthew David’s Lease-Option King and Cash Flow Fundamentals. All of them are written in collaboration with real life wealthy real estate investors using the techniques in the real world.
