FHA and authorized user accounts

Why authorized-user accounts come up at all

An authorized user can use someone else's card but is not the one legally obligated to repay. That is why the account is so often added to a young credit file: you borrow a parent's record. FHA does not ignore it. The Handbook asks the opposite question for debt: if the account carries a balance and you can spend on it, is the monthly payment part of what you owe?

The DTI rule

The rule appears identically in the automated (TOTAL) and manual underwriting sections. Accounts for which the borrower is an authorized user must be included in the borrower's debt-to-income ratio, unless the lender can document that the primary account holder has made all required payments on the account for the previous 12 months. If less than three payments have been required on the account in the previous 12 months, the payment amount must be included in the borrower's DTI regardless.

Examples. A card with a $90 minimum payment where the primary holder, a parent, paid every month for 12 months, and the lender has the statements: the $90 can be left out. The same card where the parent was 30 days late once: the $90 is included. A newly opened card with only two payments required in the last 12 months: the $90 is included even if both were on time. The checker above walks through the same three tests.

What "document" means here

The Handbook says the lender must be able to document the primary holder's payment history. The Handbook does not list the exact documents, but it is the primary holder's record that has to be shown, not just the borrower's own report. Ask the primary holder whether they are willing to share statements for the last 12 months before you promise a lender they will.

Authorized-user lines and thin credit files

For borrowers with no traditional credit, manual underwriting requires three credit references, with an option to use unreported recurring debts such as insurance premiums, child care payments, school tuition, rent-to-own and certain others. One of the allowed sources is a documented 12-month history of payment by the borrower on an account for which the borrower is an authorized user. Note the wording: payment by the borrower, not by the primary holder. Being listed on someone else's card is not by itself a credit reference.

The "no discretionary debt" compensating factor

To justify higher qualifying ratios in manual underwriting, one factor is "no discretionary debt": the housing payment must be the only open account with a balance not paid off monthly, the borrower must have established credit lines in their own name open for at least six months, and the borrower must document that those accounts have been paid off in full monthly for six months. The Handbook states that credit lines not in the borrower's name, but where they are an authorized user, do not qualify under this criterion. So being an authorized user cannot supply the six-month history that factor needs.

What to do

If you rely on an authorized-user account, work out the payment that might be counted and run it in the DTI calculator both ways. If you were removed from or added to accounts shortly before applying, expect questions. Also check how your score will be read on the minimum credit score page, and note that student loans follow a separate payment rule.
