How Alternative Credit Scoring Is Narrowing America’s ‘Credit Invisible’ Gap.

Alternative credit scoring, which scores a borrower on rent, utility and bank account data alongside a traditional credit file, is reaching a wider group of US lenders this year. The Federal Housing Finance Agency opened VantageScore 4.0, one of two mortgage credit score models built to read that data, to every approved Fannie Mae and Freddie Mac lender on 9 September 2026.

That expansion ended a limited rollout that began on 22 April 2026, when the Enterprises first accepted VantageScore 4.0 scores from a smaller group of approved lenders. The other model FHFA validated for this purpose, FICO 10T, remains unavailable for loan deliveries. FHFA says on its credit score policy page that it will give lenders separate notice once that model is ready, with no date yet set. Lenders can still use the long-standing Classic FICO score, which FHFA has not scheduled for retirement.

What ‘credit invisible’ means now

The case for alternative data usually opens with a number: 26 million Americans with no credit history at all, a figure that has circulated since a 2015 Consumer Financial Protection Bureau report. The Bureau corrected that estimate in June 2025. A data and methodology fix cut the 2010 credit invisible share from 11 percent of adults to 5.8 percent, or about 13.5 million consumers, and the Bureau’s updated estimate for 2020 put the figure lower still, at 2.7 percent of adults.

The Federal Reserve’s October 2025 Consumer and Community Context bulletin puts the correction in current terms. Of 258.3 million US adults, about 7 million have no credit record at all and a further 25 million have a thin file too sparse to produce a reliable score, a combined unscoreable population of roughly 32 million. That is smaller than the 45 million once implied by adding the original CFPB estimate to its companion unscored-records figure.

How the new models read rent, utility and cash flow data

FICO 10T and VantageScore 4.0 differ from the long-running Classic FICO score mainly in what they count. Classic FICO scores a consumer against their existing credit accounts alone. Both newer models add trended data, meaning several years of account balances and payment patterns rather than a single snapshot, and both can draw in rent, telecom and utility payments where a landlord or biller reports them to a credit bureau. FHFA validated both models for use by Fannie Mae and Freddie Mac in October 2022, after the two Enterprises tested each against existing loan files for accuracy, reliability and integrity.

The guidance behind cash flow underwriting

Feeding bank account or cash flow data into an underwriting model rests on different legal ground to a bureau score. No federal rule requires it. The Federal Reserve, the CFPB, the FDIC, the OCC and the National Credit Union Administration issued a joint statement in December 2019 encouraging lenders to use alternative data responsibly, provided the approach still complies with the Equal Credit Opportunity Act and the Fair Credit Reporting Act. A lender using cash flow data still owes a declined applicant the same adverse action notice a bureau-based decision would require.

What the Esusu rental data study found

Rent is the alternative data point regulators and consumer groups have pushed hardest to add. VantageScore and the rent-reporting platform Esusu published a study in November 2025 covering more than 600,000 renters who had shared verified, on-time payment histories. Adding that history to VantageScore 4.0 improved the model’s ability to predict future defaults by up to 11 percent, the companies found, and let close to 4 million renters reach a score of 620 or above, the threshold most mortgages sold to Fannie Mae or Freddie Mac require. Only around 13 percent of US renters currently have on-time rent reported to a bureau at all; unpaid rent reaches a bureau far more often, through collections agencies.

California, Colorado and New York passed rent-reporting laws in 2025 requiring some landlords to furnish payment data to a bureau, and several more states are weighing similar bills. The consumers most likely to benefit overlap with a group Fintechly has covered as banks face a widening youth finance gap: renters and first-time borrowers with a stable income and a bank account, but no credit card or loan old enough to produce a score.

What this means for lenders outside the mortgage pipeline

For lenders and credit-decisioning vendors outside the Fannie Mae and Freddie Mac pipeline, the FHFA rollout works as a proof point rather than a mandate. Auto lenders and credit card issuers already run their own alternative-data models and are not bound by either Enterprise’s selling guide. What the mortgage rollout demonstrates to them is that two independently validated models, built on different data, can run in production at scale without a drop in the predictive accuracy FHFA required before approving either one in 2022.

The practical effect still lags the policy change. A lender can choose VantageScore 4.0 or Classic FICO for a given loan, but not mix models between two borrowers on the same loan, and FICO 10T remains unavailable for delivery to the Enterprises altogether. A fuller list of active US lending and credit-decisioning providers working with this kind of data is on Fintechly’s lending sector directory.

Will my mortgage lender automatically use VantageScore 4.0 instead of my FICO score?

No. FHFA’s September 2026 expansion lets any approved Fannie Mae or Freddie Mac lender choose VantageScore 4.0, but adoption is optional and decided lender by lender. A lender must use the same model for every borrower on one loan, so a joint application cannot mix a VantageScore 4.0 result for one applicant with a Classic FICO result for the other.

Does paying rent on time automatically improve a credit score?

Not unless a landlord, property manager or rent-reporting platform actively sends that payment history to a credit bureau. The Esusu and VantageScore study published in November 2025 found only around 13 percent of renters currently have on-time payments reported this way, while unpaid rent reaches a bureau far more often through collections.

Does cash flow underwriting require a different consumer disclosure than a credit score decision?

Lenders using cash flow data still owe a declined or downgraded applicant the same adverse action notice required under the Equal Credit Opportunity Act and the Fair Credit Reporting Act. The 2019 interagency statement on alternative data frames this as an existing disclosure obligation, not a new one created specifically for cash flow data.

Why is FICO 10T still unavailable if FHFA approved it in 2022?

FHFA validated FICO 10T alongside VantageScore 4.0 in October 2022, but the Enterprises have moved VantageScore 4.0 through the rollout first. FHFA’s own guidance says it will set a separate timeline for FICO 10T loan deliveries; as of early October 2026, no date has been announced.
