Hello Sarah –
I do not know this answer off the top of my head. My gut says, “no”. Not until she is a legal adult. Then, I would be worried about her not having a credit score. Will you be able to obtain a GUS approval with only one borrower having an eligible credit score. You may be downgraded to a manual underwrite which will have more restrictive DTI requirements at a minimum and may require alternative credit to be built. Call your local RD office. Check with an Underwriter.
