Understanding the Shift to New Credit Score Models

For years, getting a mortgage has relied on a snapshot view of your credit. Lenders looked at your score on a specific day, focusing on factors like your current debt and payment history. But big changes are coming. The Federal Housing Finance Agency (FHFA) has approved the use of two new credit scoring models for mortgages backed by Fannie Mae and Freddie Mac: FICO 10T and VantageScore 4.0. These models don't just look at a snapshot; they watch a movie of your financial behavior, introducing a concept called 'trended data' that could fundamentally change your path to homeownership.

What is 'Trended Data' and Why It Matters for Mortgages

Trended data is the most significant change in the new scoring models. Instead of just seeing that you paid your credit card bill, lenders will now see how much you paid. They will analyze up to 24 months of your payment history to identify patterns in your behavior.

This matters because it distinguishes between two types of borrowers:

Under old models, a person with a $5,000 balance who paid the $100 minimum on time was viewed similarly to a person with a $5,000 balance who paid it off completely, as long as their credit utilization ratio was acceptable on the day the report was pulled.

With trended data, the distinction is clear. Lenders can see the person paying in full is actively managing and eliminating debt, which is a powerful indicator of lower risk. The person making minimum payments, while still paying on time, is seen as carrying more risk because their debt isn't decreasing.

Example:

Under FICO 10T and VantageScore 4.0, Borrower B will be viewed much more favorably and will likely have a higher score, even if both borrowers have the same on-time payment history and initial credit utilization.

Will Your Credit Score Go Up or Down in 2025?

There is no single answer; the impact of the new models is entirely based on your personal financial habits.

The goal of these new models is to provide a more predictive picture of borrower risk. Those who demonstrate responsible debt management and reduction will be rewarded.

How Rental Payment History Will Be Included

For the first time in conventional mortgage lending, your history of paying rent can now be a positive factor in your credit score. VantageScore 4.0, in particular, is designed to incorporate rental payment data, a move intended to help 'credit invisible' consumers or those with thin credit files build a score sufficient for a mortgage.

This is not automatic. For your rental history to be included, your landlord or property management company must report your payments to the credit bureaus. This is often done through third-party rent-reporting services. If you have a strong history of on-time rental payments, it's worth investigating if your landlord uses such a service or would be willing to. This can provide a significant boost by demonstrating a consistent ability to make a large, recurring monthly payment, which is a core behavior mortgage lenders want to see. The data, information, or policy mentioned here may vary over time.

A New Look at Credit Card Balances

Trended data revolutionizes how lenders view your credit card debt. The old focus was primarily on the credit utilization ratio, which is your total balance divided by your total credit limit. The common advice was to keep this ratio below 30%.

While utilization still matters, the new models place heavy emphasis on the payment trend. A borrower with a 40% utilization ratio who is aggressively paying down their balance could be scored higher than a borrower with a 25% utilization ratio whose balance has been stagnant for a year. The key takeaway is that demonstrating a commitment to becoming debt-free is now a quantifiable metric in your credit score. Lenders want to see a downward trajectory in your balances, proving you are a low-risk borrower who manages credit responsibly.

Outdated Credit Rules of Thumb

Some long-standing credit advice is becoming less relevant with the rollout of FICO 10T and VantageScore 4.0. Here are a few 'rules' that are now officially outdated:

How to Optimize Your Credit for the New Scoring Models

Getting your credit profile ready for these changes doesn't require a complete overhaul, just a strategic shift in focus.

Person reviewing their credit report and financial documents

Here are actionable steps to take:

  1. Pay More Than the Minimum: On every single debt account, aim to pay more than the minimum due. This creates a positive payment trend that the new models will reward.
  2. Focus on Principal Reduction: Shift your mindset from 'making a payment' to 'reducing the balance'. Create a plan to systematically pay down your highest-interest debts first.
  3. Become a Transactor: If possible, start paying your credit card balances in full each month. This is the strongest positive signal you can send under the new models.
  4. Ask About Rent Reporting: Talk to your landlord about reporting your on-time rent payments to the credit bureaus. This can add a powerful new data point to your file.
  5. Review Your Trends: Pull your credit reports and look at them through the eyes of a lender. Do your balances show a downward trend over the last 12-24 months? If not, start making changes now.

When Will Mortgage Lenders Adopt These New Scores?

The FHFA has directed Fannie Mae and Freddie Mac to begin the process of implementation. However, this is a massive technological and procedural shift for the entire mortgage industry. In response to industry feedback, the FHFA has delayed the original implementation timeline. While a new mandatory use date has not yet been set, the transition is not expected to occur before 2025. The data, information, or policy mentioned here may vary over time. This gives you a crucial window of time to adjust your financial habits and optimize your credit profile to align with what the new models value most.

With these credit scoring changes on the horizon, understanding your financial standing is more important than ever. If you're ready to take the next step towards homeownership and see how you can qualify under the new models, apply now to get a clear picture of your options.
