I've been in the lending business for 37 years, and in the last 10 years interest rates have traded within a realatively tight range of 5 - 7.5. I have never, repeat, never seen a mortgage pool offer 15% during this period. If a mortgage fund lends money to "affiliated" borrowers who buy fixers to remodel and sell, it must be explicitly disclosed, and even then an added risk disclosure would be prudent. Were these unsofisticated investors relying on the fund managers for expertise in lending or real estate development? If these properties were such good deals, why would an experienced developer pay over 15% interest plus points? Surely one wouldn't invest in a loan to an inexperienced developer/flipper, right?
