I am recently married and live in my husbands home and we are trying to sell my home. It has been on the market for over a year and we just have had no luck selling it. My husbands name is NOT on the loan so if I have to foreclose on it will that effect his credit?

I'm not a proffessional but from what I know of His name would have to be on the mortgage. Because I'm going through a foreclosuer and my husband is on the house so it will effect both of our credit.
