It is not only FHA and VA. I have a realtor friend who Refi'd in Oct 07, I would not do her loan because she needed stated and I knew what kind of money she made. I would have had to put down she made $8,000 per month for DTI. Loan amount was $345K.
She found someone from Hawaii to do a pay option Arm at start rate of I think 1.95% Stated/Stated
Loan was immediatly sold to Country Wide, she has never made a payment and has still not been foreclosed on.
