There is a new scam that is really gaining traction, seemingly targeting the charedi community specifically (I'm assuming due to the widespread lack of business knowledge), where they are selling houses that can't be sold for even
$1000, for $50k+.
Yes they are offering houses in Euclid for $50k+ (any Clevelander will actually laugh out loud when they hear that), and
guaranteeing 10% return per year for the first 3 years, plus they are advertising an average of 16% return.
Rav Ahron Chodosh has asked my brother to be mefarsim this scam, and to approach the the Jewish papers to stop the ads, and start running ads warning the public about this scam. In addition, just today, a top law firm in Israel has tentatively agreed to take on the case pro bono, and start sending out C&D letters to anyone running these ads.
I doubt this will stop them, so if you know any Israelis that may be the type to get involved in something like this, please give them a heads up. Their sales pitch is quite convincing. I know a few intelligent people that were convinced.
