If you've avoided debt your entire life — no credit cards, no auto loans, no student loans — you may have a "thin file" or no FICO score at all. FICO requires at least one account open for 6 months to generate a score.
This isn't necessarily bad financial behavior. But it makes automated underwriting impossible.
FHA loans allow manual underwriting for borrowers with no credit score. A human underwriter reviews your actual payment history instead of a FICO score.
What they'll look at: 12 months of on-time rent payments (landlord letter required), utility payments, cell phone, insurance. You'll need to document these with bank statements and letters.
For manual underwriting, lenders accept "non-traditional credit" — documented proof you pay bills on time. This includes: rent, utilities, phone, auto insurance, subscription services. Each account needs 12 months of history.
VA loans are the most flexible for thin-file borrowers. The VA doesn't set a minimum credit score — lenders do. Some VA lenders will manually underwrite with no FICO score.
Credit unions that keep loans in-house can underwrite however they want. Many will evaluate your overall financial picture rather than just a FICO score. Call local credit unions directly and ask about their thin-file or no-score policies.
If you want to build credit quickly: open a secured credit card ($200-500 deposit), use it for one small purchase monthly, pay in full. After 6 months you'll have a FICO score. After 12-18 months with perfect payment history, you may qualify for conventional financing.
