Sub-prime jumbo loans experienced the same firey death as regular sub-prime loans. When the financial and real estate markets crashed because of all the exotic mortgage loans and related financial instruments containing these and other high risk loans crashed, the world of mortgages changed forever. Fortunately, there are a very few private sub-prime jumbo loans if you have 15% to put down. There are even sub-prime commercial loans if you have 20% to put down. So gather your down payments needed for jumbo sub-prime mortgages and get going.
