Actually you'll get a much better rate if you can do a SIVA (stated income/verified assets)
Couple other points for this program:
You'll need a continuous 2 year history of employment in the same industry if w2 or poof of being self employed for 2 years.
Negative cash flow may come up with a couple of the lenders that your consultant looks. It would be best to try avoiding a lender that has that restriction.
It requires that you have 6 months of the expected mortgage payment (including taxes/insurance) in liquid assets like checking, savings, 401k, stock, etc Those funds need to have been in your account for at least 2 months.
There's several other things to look out for.
