Alternative Credit Data
Alternative credit data refers to information used to evaluate creditworthiness that doesn't come from the three major credit bureaus. Common sources include bank account transaction history, rent payment records, utility payment history, and reports from specialty subprime bureaus like Clarity Services, FactorTrust, and DataX. Subprime lenders rely heavily on alternative data because traditional credit scores often don't capture enough information about borrowers with thin or damaged files.
Alternative credit data is what makes subprime lending possible at scale. Traditional FICO scoring requires at least six months of credit history with at least one tradeline, and it weights credit card and installment behavior heavily. For someone with a thin file, a recent bankruptcy, or a credit history that’s mostly negative, the FICO score doesn’t actually predict default risk well. Alternative data fills the gap.
What lenders actually look at
When you connect your bank account during a loan application (typically through Plaid, MX, or Finicity), the lender pulls 60-90 days of transaction history. They’re looking at:
- Income deposits: frequency, amount, employer name
- Spending patterns: does your behavior match your stated income?
- Overdraft frequency: how often do you go negative?
- Existing loan payments: what other lenders are you paying?
- Average balance: do you maintain a buffer?
This data often predicts default better than credit score alone for subprime borrowers. Someone with a 540 FICO and a stable bank account is a much better lending risk than someone with a 540 FICO and three overdrafts in the last month.
The specialty bureaus
Several companies specifically track subprime lending activity:
- Clarity Services (owned by Experian)
- FactorTrust (owned by TransUnion)
- DataX (owned by Equifax)
- MicroBilt
- CoreLogic Teletrack
These bureaus collect data from non-bank lenders that don’t report to the major bureaus. If you’ve taken payday loans, online installment loans, or other subprime products, your activity is probably tracked by one or more of these even if it doesn’t show on your traditional credit report.
This is why “no credit check” loans aren’t really no-credit-check: most are pulling alternative bureau data instead.
