I believe you are referring to the income limits and the max home values. I am certain that there is some addtional documentation but IF you do qualify it seems to be the way to go.
In the student loan industry lenders waive fees and offer incentives. Do you know if lenders compete by waiving fees in these programs. By this I mean there is typically a 1.5% origination fee for the CHAFA loan. Will lenders waive this fee in the interests of competition.
