Authorized User

How Authorized User Accounts Affect Mortgage Applications

When someone is added as an authorized user on a credit card, the entire history of that account, including the credit limit, balance, payment record, and age, is reported on the authorized user's credit report. If the primary account holder maintains a low balance and perfect payment history, the authorized user benefits from an improved credit profile. Conversely, late payments or high utilization on the primary account negatively affect the authorized user's credit.

Lender Treatment of Authorized User Tradelines

Mortgage lenders handle authorized user accounts with varying levels of scrutiny. Fannie Mae's Desktop Underwriter (DU) includes authorized user tradelines in the credit evaluation unless the underwriter excludes them. Freddie Mac's Loan Product Advisor (LPA) may disregard authorized user accounts that appear to inflate creditworthiness without demonstrating the borrower's own repayment ability.

FHA guidelines permit authorized user tradelines to count toward the minimum tradeline requirements, provided the borrower can demonstrate a pattern of responsible credit use. However, if authorized user accounts are the only tradelines on the report, some lenders require additional documentation or may apply manual underwriting standards.

Strategic Considerations

Adding a borrower as an authorized user on a well-managed account is a legitimate strategy for building credit history, particularly for borrowers with thin files. However, lenders may ask the borrower to document the relationship with the primary account holder. If the authorized user tradeline is the primary driver of credit score improvement, underwriters may re-evaluate qualification without that account to test whether the borrower qualifies independently.
