Buying a house with co-signor after BK. . .

[millerc507]

My husband and I had to close our business in 5/06. We therefore had to assume a large portion of the debt the business had accumulated but we had guaranteed. As a result, we are filing BK. We are filing by the end of August. We moved to a better job market and bought a house in 11/06. The current equity in our house is held in Deed of Trust by my dad who loaned us the 20% down payment. Anyway, we bought too much house and the only job my husband could find was an hour way. He has been commuting since 11/06. The cost-of-living is much less in the town where he currently works. After our case is closed, we would like to sell our house with a current mortgage of $210K + $56K to my dad, and purchase a house closer to his job. We would like to downsize and have a mortgage of around $120K and pay back a portion to my dad, only borrowing $30K from him for the new house. We want to buy a $150K house. He will co-sign for us if necessary and his credit scores are 800+. Will we be able to get a competitive rate with 20-30% down and a highly qualified co-signor. We have been with the same lender for a number of years. Will they take this into consideration?
