When you co-sign a loan, the entire monthly payment is added to your debt-to-income (DTI) ratio, which can significantly reduce your borrowing power and affect your mortgage approval.
You can often have this co-signed debt excluded from your DTI calculation by providing specific documentation to your lender.
The primary requirement is to show 12 consecutive months of on-time payments made directly by the primary borrower. This proof must come from their complete bank statements or canceled checks.
Be aware that a single late payment made by the primary borrower within the last year will reset the 12-month clock, forcing you to wait longer to apply.
The most definitive way to resolve the issue is to be formally removed from the loan, either through a co-signer release clause or by the primary borrower refinancing the debt in their name only.
