Tradelines
What are tradelines?
Credit accounts reported to credit bureaus — the depth and history of your credit file as seen by a mortgage underwriter.
A tradeline is any credit account that reports to one of the three major U.S. credit bureaus — Experian, Equifax, and TransUnion. Common tradelines include credit cards, auto loans, student loans, personal loans, and existing mortgages. Each tradeline carries data about the account: the credit limit, current balance, payment history (on-time, 30/60/90-day delinquencies), date opened, and current status.
Mortgage underwriters look at two dimensions of your credit file: your FICO score (a numeric distillation) and the depth and quality of your tradelines (the underlying account history). A 740 FICO with one short-history card looks weaker than a 720 FICO with five seasoned accounts. Tradeline requirements protect against artificially inflated scores on thin files.
Authorized-user tradelines (where you’re added to someone else’s account) are treated more conservatively and often excluded if they appear to be the only credit on file.
How tradelines apply at Total Quality Lending
Total Quality Lending’s underwriting requires either:
- 2 tradelines reporting at least 24 months with activity in the most recent 12 months, OR
- 3 tradelines reporting at least 12 months with recent activity.
Borrowers with three valid credit scores (one from each bureau) have the tradeline-depth requirement waived. This applies across DSCR, Prime Time, and Multi-Unit DSCR programs.
