HELP!!! which course to choose?

Hi, I wonder if anyone can help me. I am very interested in getting into real estate investment, rehabbing in particular. There are so many courses out there and they all look like they too good to be true. Have any of you bought one and had any success? Iv been looking at Thomas Kish and have seen many people on here looking for information on him but cant find any responses? Has anyone out there actually bought his programme and has it worked for you. Very interested to know…
