If it’s such a sure thing, why aren’t you out there doing that instead of sitting in a studio recording a video? And furthermore, why would you want to attract competition to the market from which you derive such a fortune? You’d think you’d be killing anyone who figured it out on their own just to keep the secret all to yourself.
Years ago I kept getting (maybe twice a week) a letter from a fortune teller, who, for a small donation, would tell me what the winning lottery numbers were going to be on any given day, what my lucky number was, etc, etc. so I could get rich fast. Normally, I would throw the stuff in the trash but this one time, I wrote back that if he/she knew what the lottery numbers were going to be on a given day, why didn’t he/she just play the lottery and quit asking me for money! Never heard from he/she again.
To be fair, isn’t it possible that a person could conceivably become a millionaire in the residential market, and then want to share what he learned with others? IF all things are equal (including the state of the market and the economy), the successful flipper/instructor would by then have amassed enough captial to move into the riskier and higher-cost apartment/hotel redevelopment market, and holding classes for beginners could help pay the bills for that leap.
Not all businessmen are shysters. But almost everyone who wants a get-rich-quick approach to life without being willing to work hard is going to fall prey to the dishonest ones.
