The companies that buy up the majority of the country’s home loans will now accept a second credit scoring model for mortgages — a change that could help underrepresented borrowers qualify for financing.

Fannie Mae and Freddie Mac, the two government-backed companies that support about 70% of the US mortgage market, will allow lenders to use VantageScore 4.0, a credit scoring alternative to FICO, Bill Pulte, the director of the Federal Housing Finance Agency, wrote in a post on X Tuesday.

The move is designed to end FICO’s near-monopoly on credit scoring in mortgage underwriting, lower closing costs, and expand credit to borrowers whose payment histories aren’t well captured by FICO.

Credit scores are a key factor in determining if a prospective homeowner qualifies for a mortgage, and what interest rate they’ll pay. It usually takes a credit score of at least 620 to qualify for the most common type of loan, known as a conventional mortgage. It takes a significantly higher score, often a 750 or above, to receive the lowest interest rates.

For years, FICO was effectively the only company providing credit scores. To determine creditworthiness, it considers factors including payment history, amounts owed, and how long a borrower has had credit. Without a score and a previous borrowing history, it can be hard to gain access to credit, but it also takes access to credit to build a credit history, a classic chicken-and-egg conundrum.

VantageScore was created by the three major credit bureaus, Experian, Equifax, and TransUnion, in 2006 as an alternative to FICO. Its scores use the same 300 to 850 scale as FICO, and its latest model, VantageScore 4.0, is designed to more closely look at consumers with limited credit histories, in part by allowing rent and utility payments to factor into a credit file.

“My ORDER today (thanks to my boss, POTUS) will allow for Americans to use their RENT to qualify for a mortgage. Credit history will no longer just include credit cards and loans. This is HUGE,” Pulte posted.

Rick Roque, vice president for growth at NFM Lending, said the move should help more members of traditionally underrepresented communities, like Black, Latino, and immigrant borrowers, build credit and ultimately qualify for loans.

“There are probably 30 million or more people that are considered underbanked,” Roque said. “They get relegated to renting, so there’s a whole aspect of equity, wealth, and real estate that isn’t built up.”
