When Nontraditional Credit Applies
Fannie Mae allows nontraditional credit when you don't have a credit score or have limited traditional credit history. This happens when you haven't used credit cards, auto loans, or other traditional credit products enough to generate a credit score.
Your lender must first check all three major credit bureaus — Experian, Equifax, and TransUnion — to confirm you truly lack traditional credit. The credit report will specifically indicate that a score couldn't be produced due to insufficient credit history.
Say you're a recent college graduate who always paid cash for everything, or an immigrant who just arrived in the U.S. and hasn't established credit yet. If the credit bureaus can't generate a score for you, nontraditional credit becomes an option.
What Qualifies as Nontraditional Credit
Nontraditional credit references include payment histories that aren't reported to credit bureaus but demonstrate your ability to pay bills on time. These include rent payments, utility bills, insurance premiums, cell phone bills, and childcare payments.
Your lender needs to document at least 12 months of payment history for each reference. The payments must be substantial enough to matter — typically at least $50 per month — and must show consistent, on-time payment patterns.
Housing payment history carries special weight. If you can document 12 months of rent payments or previous mortgage payments, you won't need to maintain cash reserves. Without housing payment history, you'll need 12 months of mortgage payments in reserve accounts.
Strict Loan Requirements
Loans using nontraditional credit face tighter restrictions than standard Fannie Mae loans. The property must be a one-unit primary residence — no condos, investment properties, or vacation homes. You must live in the home yourself.
The loan amount cannot exceed baseline conforming limits, which means high-balance loans are off the table. For 2024, this means loan amounts up to $766,550 in most areas, with higher limits in expensive markets but still below the high-balance thresholds.
Your debt-to-income ratio cannot exceed 36%. This includes your new mortgage payment plus all other monthly debt obligations like car payments, student loans, and credit card minimum payments.
Required Documentation
Your lender must document each nontraditional credit reference with written verification from the creditor or service provider. This means getting letters from your landlord, utility companies, insurance providers, and other payees.
Each verification letter must show your payment history for at least 12 months, including payment amounts, due dates, and any late payments. The letters must come directly from the creditor — you cannot provide your own payment records as proof.
Bank statements showing automatic payments can supplement but not replace creditor verification letters. The lender needs to see both the payment going out of your account and confirmation from the creditor that they received it on time.
When Nontraditional Credit Won't Work
You cannot use nontraditional credit if you actually have a credit score but it's too low to qualify. If the credit bureaus can generate a score for you — even a poor one — you must use traditional credit guidelines and work on improving your score.
Previous bankruptcies or foreclosures also disqualify you from nontraditional credit. You must wait through the required waiting periods and re-establish traditional credit with actual credit accounts before applying. See [[B3-5.3-07]] for specific waiting period requirements.
If you have significant derogatory credit events in your past, nontraditional credit cannot bypass those issues. Fannie Mae requires you to rebuild your credit the traditional way after major credit problems.
Desktop Underwriter Considerations
When at least one borrower has some traditional credit accounts — even without a full credit score — Desktop Underwriter (DU) will assess the loan using standard guidelines rather than nontraditional credit rules.
If no borrower has any traditional credit accounts, DU applies special requirements. The property can be up to four units (not just one unit), but all borrowers must occupy the property. DU may require reserves based on its risk assessment.
DU sometimes issues messages allowing third-party asset verification reports to satisfy nontraditional credit requirements. This can streamline the documentation process, but you still need to provide whatever DU specifically requests.
Common Complications
Payment histories from family members don't count as nontraditional credit references. You cannot use payments to parents, siblings, or other relatives to establish creditworthiness, even if you have documentation.
Irregular payment amounts create problems. If your rent varied significantly month to month, or if you frequently paid utilities late, these patterns may not support loan approval even with proper documentation.
International credit histories require special handling. If you have credit history from another country, your lender may need to obtain specialized credit reports or translations, which can complicate the nontraditional credit process.
Manual Underwriting Requirements
All loans using nontraditional credit must be manually underwritten — no exceptions. This means a human underwriter reviews your entire file rather than relying on automated approval systems.
Manual underwriting takes longer than automated processing, typically adding 1-2 weeks to your loan timeline. The underwriter will scrutinize every aspect of your financial profile more carefully than in automated underwriting.
Non-occupant co-borrowers are allowed but must meet additional requirements outlined in [[B2-2-04]]. Having a co-borrower with traditional credit can strengthen your application but doesn't eliminate the nontraditional credit documentation requirements.

Overview
If one or more borrowers do not have a credit score or have a limited traditional credit history, the lender must establish an acceptable nontraditional credit history. The lender must first check all three major credit repositories to verify the borrower’s credit history.
The credit report will indicate if a credit score could not be produced due to insufficient credit. Lenders must ensure that the credit report accurately reflects the borrower’s information, such as the name, Social Security number, and current residence of the borrower to confirm that the lack of traditional credit was not erroneously reported because incorrect information was used to order the credit report.
Manual Underwriting
If one or more borrowers on the loan does not have a credit score and is relying on nontraditional credit to qualify, the following requirements apply:
The property must be a one-unit, principal residence.
Non-occupant co-borrowers are permitted, provided the requirements described in B2-2-04, Guarantors, Co-Signers, or Non-Occupant Borrowers on the Subject Transaction, are met in addition to the eligibility requirements described herein.
The transaction must be a purchase or limited cash-out refinance.
The loan amount must meet the baseline loan limits—high-balance mortgage loans are not eligible.
The maximum debt-to-income ratio is 36%.
There is no minimum reserve requirement if at least one borrower can document a housing payment history as one nontraditional credit reference. Otherwise, a minimum of 12 months reserves is required. See B3-5.4-02, Number and Types of Nontraditional Credit References, for additional information.
A nontraditional credit history must be documented for each borrower without a credit score. See B3-5.4-03, Documentation and Assessment of a Nontraditional Credit History, for additional information.
Unacceptable Uses
The establishment of a nontraditional credit history is not acceptable for the following scenarios:
The lender is able to obtain a credit score for the borrower despite the borrower’s limited use of credit.
The borrower has a sufficient amount of credit to obtain a credit score and the representative credit score is less than the minimum required.
Note: An exception is permitted for certain HomeReady loans for borrowers with low credit scores. See
B5-6-02, HomeReady Mortgage Underwriting Methods and Requirements, for additional information.
The borrower’s traditional credit history indicates significant derogatory references, such as a prior bankruptcy or foreclosure. In these cases, the borrower must have re-established credit in accordance with B3-5.3-07, Significant Derogatory Credit Events — Waiting Periods and Re-establishing Credit, including the establishment of traditional credit and a credit score.
DU Loan Casefiles
When at least one borrower has a minimum of one credit account or installment account reported on their credit report, DU will assess the risk using the borrower's reported credit and the loan will be subject to standard eligibility guidelines.
When no borrower has at least one credit account or installment account reported on their credit report, DU will apply the following requirements:
The property must be a one- to four-unit, principal residence, and all borrowers must occupy the property.
The transaction must be a purchase or limited cash-out refinance.
Reserves may be required as determined by DU.
In both cases, no verification of nontraditional credit references is required for any borrower when DU conducts a cash flow assessment and issues a message that the third-party asset verification report may be used to satisfy the requirements. Otherwise, a nontraditional credit history must be documented for each borrower as instructed by DU. See B3-5.4-03, Documentation and Assessment of a Nontraditional Credit History, for additional information.
If a loan casefile does not receive an Approve/Eligible recommendation, it may receive a more favorable recommendation if a 12-month asset verification report is obtained (see B3-2-03, Risk Factors Evaluated by DU). In some cases the loan may still be eligible for manual underwriting. The lender must determine whether the loan meets the requirements for a manually underwritten loan that includes a borrower without a credit score.
