Bridge loans backed by collateral in solid, often family-owned, small companies. The companies grow so fast that they need multiple sources of funding, including from banks and outside investors, and the extra income generated by the loan far exceeds the 15% annual interest rate. There is almost no risk because the collateral, e.g., houses, cattle, etc., exceeds the value of the loan. Typically in the 8%-10% range, but you can find them up to 15% or more.
