I have to agree with most of the mortgage lenders answer.
Your husband is no longer considered a first time home buyer since he is on the Deed (Title) on the property and owns with you that piece of property together. The mortgage in this case will not be considered since this mortgage only regulates who pays for the debt.

I do not pretend to know all lender's definitions, however...just the one's I work with and the FHLB, FHA, Fannie and Freddie definitions.
