The old rule of needing a 620 credit score to buy a house is fading fast. Starting in 2026, lenders will look beyond just your FICO score, using new models that consider rent, utilities, and how your credit changes over time. This shift means more people, especially first-time buyers and renters, could qualify for mortgages in ways that didn’t exist before. Here’s what you need to know about these important mortgage credit score changes. Learn more about financing options for foreign nationals.
The Evolution of Mortgage Credit Requirements
Farewell to the 620 Minimum Score
The longstanding requirement of a 620 FICO score for conventional loans is becoming obsolete. Companies that provide capital to the mortgage market are expanding their view of credit profiles, which promises to make credit available to many previously underserved borrowers.
Changes to Conforming Loans
The Federal Housing Finance Agency (FHFA), which oversees Freddie Mac and Fannie Mae, has mandated broader credit scoring models. These organizations provide capital for conforming conventional loans, which finance more than half (56.5% in 2024) of home loans in the U.S.
If you’re buying a house valued under $832,750 in 2026 without using a government loan (VA, FHA, or USDA mortgage), your lender will likely use a conforming conventional loan.
Notably, Fannie Mae eliminated its minimum credit score requirement on November 15, 2025. Instead of relying solely on credit scores, risk decisions will now consider various factors such as borrower reserves, debt levels, property characteristics, and loan purpose.
New Credit Scoring Models
Beyond Traditional FICO Scores
Mortgage lenders will soon incorporate VantageScore 4.0 and FICO 10T models, which analyze more than typical credit histories. Both models use “trended data” to gain a more comprehensive view of consumer credit behavior over time, rather than just looking at a specific day’s credit score.
Alternative Data Consideration
A key feature of both new scoring models is the inclusion of alternative credit data. This considers payment histories for rent, utilities, and phone services, which can help establish creditworthiness for those with limited traditional credit history.
Julie May from FICO notes that these new models will “expand access to credit for traditionally underserved groups such as first-time homebuyers, young adults, and renters.”
VantageScore 4.0 is already available to Fannie Mae and Freddie Mac, while FICO 10T will roll out in early 2026.
Reality Check on Credit Requirements
Credit Scores Still Matter
While Fannie Mae and Freddie Mac may not require specific credit scores, the loan approval process remains largely unchanged. As FHFA director William J. Pulte stated, “Our underwriting standards are the same.”
Still, VantageScore estimates that approximately 5 million prospective buyers will benefit from the new credit modeling.
Lender Discretion Continues
Lenders can choose whether to use classic FICO scores or the new creditworthiness models. If you have a thin credit file or no credit score, you’ll want to shop for a lender that accepts alternative credit data. Guild Mortgage and AmeriHome, for example, already accept alternative credit information from mortgage applicants.
Why Credit Scores Remain Important
Even with these changes, credit scores still play a vital role when buying a house:
-
Better credit scores qualify you for lower mortgage rates and reduced lender fees
-
Higher scores attract more lenders to compete for your business
-
Strong credit can allow for smaller down payments
-
Better scores can reduce mortgage insurance costs
What This Means for You
These new credit models represent a significant shift in how lenders evaluate borrowers. As Vishal Garg of Better Mortgage explains, they “reflect how people really earn and spend today” and provide “a much clearer view of a borrower’s true risk.”
For potential homebuyers, especially those with non-traditional credit histories, these changes could open doors that were previously closed. If you’re planning to buy a home in 2026 or beyond, understanding these new evaluation methods can help you prepare better for the mortgage application process.
For foreign investors and first-time buyers alike, these changes represent a more nuanced approach to credit evaluation that better reflects today’s financial realities.
New Mortgage Credit Score Models
The mortgage industry is changing how it looks at your creditworthiness. Gone are the days when a single number from FICO determined your fate. Starting in 2026, lenders will use more sophisticated tools that paint a fuller picture of how you handle money.
Trended and Alternative Data Insights
Trended data tracks how you manage credit over time instead of taking a single snapshot. This means lenders can see if you’re paying down balances or maxing out cards month after month.
The new scoring models look at 24 months of account activity. They notice if you’re making more than minimum payments, which signals good financial habits. They also spot if you’re slowly building up debt, even if you’ve never missed a payment.
Think of it like this: the old system was like judging a movie by its poster. The new system watches the whole film to see how the story develops.
For many people who manage money well but don’t have perfect credit histories, this approach offers a fairer assessment. The models reward positive trends in your financial behavior, not just your past mistakes.
Expansion of Credit Profiles
The new credit models don’t just look at different timeframes – they look at different types of payments altogether. This means your on-time rent payments can finally help your mortgage application.
FICO 10T and VantageScore 4.0 consider payments that never showed up in traditional credit reports. Did you pay your cell phone bill on time for years? That counts now. Have you been a model tenant who never misses rent? That matters too.
This change helps millions who pay bills responsibly but have thin credit files. Young adults, immigrants, and people who prefer cash can now build credit history through everyday payments.
For example, a teacher who pays rent on time but has few credit cards might now qualify for a mortgage when they couldn’t before. A recent graduate with student loans but little other credit history can show financial responsibility through utility payments.
This expansion means your full financial life – not just your credit card usage – shapes your mortgage options.
Impact on Homebuyers
The credit score changes will reshape who can buy homes and at what terms. These shifts may open doors for millions previously locked out of the housing market due to outdated credit evaluation methods.
Changes in Minimum Credit Score Requirements
Fannie Mae has already eliminated its fixed minimum credit score requirement. This doesn’t mean they’ll approve everyone, but it does mean they’ll look at your full financial picture rather than rejecting you based on a single number.
The mortgage world is moving from strict cutoff points to more flexible, personalized assessment. Your debt-to-income ratio, payment history, and cash reserves now carry more weight in decisions.
This shift helps people whose scores don’t reflect their true risk level. Maybe you had a medical emergency that hurt your credit temporarily. Or perhaps you’re self-employed with solid income but complex credit needs. The new approach considers these situations.
For some buyers, this means qualifying for a conventional loan instead of an FHA loan, which can save thousands in mortgage insurance costs. For others, it means qualifying at all when they previously couldn’t.
Remember though – while Fannie Mae and Freddie Mac are changing their requirements, individual lenders may still set their own minimum scores.
Implications for First-Time Buyers
First-time homebuyers stand to gain the most from these credit scoring changes. Many young adults and working families have been responsible with money but haven’t built traditional credit profiles that impress lenders.
The new models recognize that paying rent on time for years shows you’ll likely pay a mortgage on time too. This helps renters make the jump to ownership without years of credit card use first.
Consider this: about 45 million Americans have thin credit files or no scores at all. Many are financially stable but haven’t used traditional credit products. The new models could help millions of these potential buyers.
First-time buyers also benefit from more accurate risk assessment. When lenders can better predict who will repay loans, they can offer better rates to more people. This means some buyers might qualify for loans with smaller down payments or better terms than before.
For diverse communities historically underserved by mortgage lenders, these changes could help close the homeownership gap that has persisted for generations.
Navigating the Mortgage Market
With credit scoring systems changing, smart homebuyers need new strategies to find the best mortgage deals. Your approach to lenders and credit management matters more than ever.
Choosing the Right Lender
Not all mortgage lenders will embrace these new credit models at the same pace. Some will stick with traditional FICO scores while others will fully adopt the new systems.
Call lenders directly and ask which credit models they use for mortgage decisions. Ask specifically if they accept alternative data like rent payments or utility bills. This simple question can save you from applying with lenders who won’t value your full payment history.
Local banks and credit unions often take a more personal approach to lending. They might be more willing to consider your complete financial picture beyond just credit scores. Similarly, mortgage brokers who work with multiple lenders can help match you with those using newer credit models.
Online lenders sometimes lead in adopting new technologies, including updated credit scoring. Companies focused on first-time buyers may be particularly quick to use models that benefit their target customers.
Remember that getting quotes from multiple lenders is even more important in this changing landscape. Different lenders might evaluate the same financial profile very differently.
Maintaining a Strong Credit Profile
While credit scoring is changing, good financial habits remain crucial. The fundamentals of building a strong profile are more important than ever.
Pay all bills on time – not just credit cards but also rent, utilities, and phone bills. Since more of these payments will show up in credit evaluations, consistent on-time payment matters across all accounts.
Keep credit card balances low relative to your limits. The new models still care about how much of your available credit you use. Try to keep utilization below 30% of your limits.
Don’t open many new accounts right before applying for a mortgage. While the new models better understand rate shopping, multiple new credit lines still raise questions about your stability.
Check your credit reports regularly to ensure accuracy. With more data feeding into decisions, there are more opportunities for errors. Get free reports from annualcreditreport.com and dispute any mistakes.
Finally, build savings alongside credit. The new evaluation methods look at your overall financial stability, including reserves for emergencies and down payments. A strong savings history complements good credit behavior.
