Late-night TV is replete with real estate infomercial gurus, all plying their courses or seminars. The most well-known currently is the Armando Montelongo scam - well-known because Mr. Montelongo is the former star of A&E's "Flip This House.
I refer to it as a scam because it fits the definition of the word. First, he entices you to attend a "free" seminar that is designed to teach you just enough to get you fired up - enough so you will shell out $1500 for the second, 3 day seminar. And that seminar is designed to convince you to jump on board for his $40,000 bus tour, in order to protect your $1500 investment.
Most of the "gurus", even the Carlton Sheets scam use some version of this tactic. But there are legitimate real estate investing courses. For example, "The Simple Man's Guide to Real Estate" offered on a non-profit basis by IntelliBiz is a low cost alternative that is also the most comprehensive and effective choice. It even includes free mentoring by an actual investor. It's worth checking out.
Unlike all the other real estate courses, "The Simple Man's Guide to Real Estate" is affordable to all (under $100 complete), and has an A+ rating with the Better Business Bureau. It teaches all 22 methods of investing in real estate, including many different methods of "flipping".
They also offer membership in their new V.I.P. Club which includes many other great benefits, including phone consultations with the author, Bill Vaughn, and a guarantee of closing on at least (4) properties your very first year.
To date, IntelliBiz has served over 150,000 members, and has a success rate that puts all other real estate investing courses
