That’s like saying we shouldn’t attack drug dealers as a group, the very line of work is bad for society, in nearly every case I’ve seen with a wholesaler they have paid less to a homebuyer, than that homebuyer could have gotten on the market, it’s why investors, myself included like them, but it by definition is a disreputable line of work, if it’s legal and still want to do it, go ahead but don’t think your gonna get a good star for making money in a line of business that exploits old people.
