Yes it is possible... you really need to look at USDA though.
USDA is 100% w/ NO MORTGAGE INSURANCE at all.
click on the left "Single Family Housing-Property Eligibility"
You can put in an address and see if it is eligilbe or go to the county/city you are looking in.
I have more information on my site as well.
I put people in this program all day long, even those that can put 20% down. It is excellent!
According the FHA mortgage brokers that I use, obtaining an FHA loan is possible after 2 years from BK-7 discharge date. I think you must have re-established good credit history and have paid other bills on time. Best to go straight to the source though and talk to a reputable mortgage broker who does FHA loans.
