🎯 TL;DR — Quick Answer
Fannie Mae now averages the credit scores of all co-borrowers on a conventional loan application, rather than using the lowest score. This significant policy change can make it easier for couples and partners with different credit profiles to qualify for a mortgage.

Understanding the Shift in Credit Requirements
📌 From Tim — In Practice
In practice, this is a game-changer for many couples I work with. Previously, a single lower score could derail an entire application, forcing us to explore other, sometimes more costly, loan options. Now, we can use the average score, which often results in a stronger file and may lead to better loan terms. It opens the door for many deserving borrowers who were previously shut out.
If you have been sitting on the sidelines because one partner’s credit score isn’t quite where it needs to be, the mortgage landscape just shifted in your favor. For years, the conventional loan process was tethered to a rigid rule that often penalized couples and co-borrowers. If one person had a stellar score and the other had a lower one, some lenders were forced to use the lower of the two to determine eligibility.
Fannie Mae has introduced a significant change to how credit scores are calculated for multi-borrower applications. This shift effectively lowers the barrier for entry for thousands of families and real estate investors. By focusing on a more balanced view of a household’s creditworthiness, the path to homeownership has become wider and more accessible than it has been in decades.
This update isn’t just about making it easier to get a “yes” from an underwriter; it is about recognizing the financial reality of modern households. Whether you are looking to purchase your first home or you are an investor looking to expand your portfolio, understanding these new nuances is essential for securing the best possible terms on your next mortgage.
How the “Average Median” Score Changes the Game
To understand why this is such a big deal, you first have to understand how things used to work. Traditionally, if you and a co-borrower applied for a loan, some lenders would pull three scores for each person. They would take the middle score for both, and then use the lowest of those two middle scores to qualify the loan.
This meant that if you had a 780 credit score and your spouse had a 640, the entire loan was priced and judged based on that 640. This often led to higher interest costs, higher private mortgage insurance (PMI) premiums, or even an outright denial. It essentially ignored the financial strength of the stronger borrower.
Under the updated guidelines, Fannie Mae allows for the use of an “average median” score. Instead of defaulting to the weakest link, the system can now take the average of the two median scores. In the 780 and 640 scenario, your qualifying score could potentially be viewed as a 710. This jump can move you into an entirely different pricing tier, potentially saving you thousands over the life of the loan.
Improving Your Qualifying Power
This change is particularly beneficial for borrowers who may have a “thin” credit file or those who have suffered a temporary financial setback. By averaging the scores, your overall profile becomes more representative of your actual ability to repay the debt. It acknowledges that the person with the higher score is just as responsible for the mortgage as the person with the lower score.
For investors, this is a massive win. If you are partnering with someone to buy a rental property, you no longer have to worry that their slightly lower score will tank your ability to get a conventional loan. You may qualify for lower down payment options or better terms than were previously available under the old “lowest-common-denominator” rules.
It is important to note that while this averaging helps with eligibility and pricing, some lenders still have a “floor” or a minimum threshold that at least one borrower must meet. Typically, a score of at least 620 is still the baseline for conventional financing, but the way you reach that threshold is now much more flexible.
The Move Toward Modern Credit Models
The mortgage industry is also in the middle of a broader transition toward more sophisticated credit scoring models. For decades, the “Classic FICO” was the only game in town. Now, government agencies like Fannie Mae and Freddie Mac are moving toward FICO 10T and VantageScore 4.0.
Why does this matter to you? These newer models use “trended data.” Traditional scores only look at a snapshot in time—what you owe right now. Trended data looks at your behavior over the last 24 months. It sees if you are someone who pays off your credit cards every month or if you are someone who only pays the minimum and carries a growing balance.
If you are a responsible borrower who pays down debt consistently, these new models may actually give you a higher score than the old ones. This modernization, combined with the averaging of scores for co-borrowers, represents a total overhaul in how your financial health is evaluated. It is designed to be more inclusive and more accurate.
What This Means for Debt-to-Income Ratios
When your qualifying credit score improves due to averaging, it can also have a ripple effect on your Debt-to-Income (DTI) ratio. Higher credit scores often allow for slightly more flexibility in how much total debt you can carry relative to your income. This can be the difference between qualifying for the home you want and having to settle for something smaller.
If you are wondering how your current financial situation stacks up, you might be asking: Can I use the equity in my house to buy another home? With these new credit rules, using your existing equity to expand your real estate footprint has become a more viable strategy for many homeowners who previously felt stuck due to credit constraints.

Opportunities for Real Estate Investors
Investors are often the most sensitive to credit score fluctuations because they frequently carry multiple mortgages. In the past, as an investor’s credit score dipped slightly due to high credit utilization or multiple inquiries, their ability to acquire new properties would diminish. The new Fannie Mae approach provides a much-needed cushion.
When you are purchasing a 2-4 unit property, the requirements are generally stricter than for a single-family home. However, by averaging scores with a partner or a co-investor, you may qualify for conventional financing on these multi-unit properties with more favorable terms. This allows you to keep more capital in your pocket for renovations or future acquisitions.
Furthermore, because conventional loans typically offer the lowest rates and the most flexible terms compared to specialized investment products, staying within the Fannie Mae framework is usually the goal. These updates make staying “in-the-box” for conventional financing much easier for the average investor.
Leveraging Rental Income
One of the best parts about conventional loans for investors is the ability to use projected rental income to help qualify. When you combine this with a higher “average” credit score, your borrowing power increases significantly. You are no longer just relying on your W-2 income and your solo credit score; you are leveraging the full strength of your partnership and the property itself.
If you are looking to scale your portfolio, you might want to consider how your current assets can play a role. You might ask yourself, How do mortgage rate buydowns actually work? Combining a higher averaged credit score with a temporary or permanent rate buydown can make a property cash-flow much better in the early years of ownership.
Conventional Loans vs. Government-Backed Options
With these new, lower barriers for conventional loans, many borrowers who previously would have been “steered” toward FHA loans may now find that a conventional loan is the better choice. FHA loans are great for their low down payment requirements, but they come with permanent mortgage insurance that can be costly over time.
Conventional loans, on the other hand, allow you to cancel your private mortgage insurance (PMI) once you reach 20% equity in the home. Because the new Fannie Mae rules might give you a higher qualifying score through averaging, your PMI rates will likely be lower than they would have been under the old rules. This makes the monthly payment on a conventional loan much more competitive with FHA options.
For many, the goal is to get into a conventional loan as quickly as possible. These loans generally have fewer “hoops” to jump through regarding property condition and offer more flexibility for different property types, including condos and planned unit developments (PUDs).
Navigating Complex Property Types
Sometimes, the hurdle isn’t your credit score, but the property itself. For example, if you are looking at a condo that doesn’t meet standard requirements, you might ask: What is a non-warrantable condo and can I get a mortgage on one? While Fannie Mae has specific rules for condos, having a stronger averaged credit score can give you more options if you need to pivot to different loan programs or seek exceptions.
The key takeaway is that the “minimum” score is no longer a single point of failure. It is now a component of a broader, more holistic view of your financial life. This flexibility is a direct response to the need for more housing inventory and more qualified buyers in the marketplace.
Preparation Tips for Your Next Application
Even with more flexible rules, you should still take steps to ensure your credit profile is as strong as possible before you apply. Since the “average” of the median scores is now the standard, both you and your co-borrower should focus on small improvements that can move the needle.
- Pay down revolving balances: Keeping your credit card utilization below 30% is typically the fastest way to see a score increase.
- Don’t open new accounts: Avoid opening new credit cards or taking out auto loans in the months leading up to a mortgage application.
- Check for errors: Ensure there are no mistakes on your credit reports from the three major bureaus. Even a small error can drag down a median score.
- Stay consistent: Ensure all payments are made on time, as even one late payment can have a significant impact on your FICO score.
By focusing on these areas, you can maximize the benefit of Fannie Mae’s new averaging policy. If you can push your individual median score up by just 20 points, and your partner does the same, your averaged qualifying score could jump into a whole new category of savings.
Remember that every lender has their own specific overlays and requirements. While Fannie Mae sets the general guidelines, some lenders may have additional rules. Working with a mortgage expert who understands the nuances of these conventional updates is the best way to ensure you are getting the most out of the current lending environment.
Conclusion: A New Era for Home Financing
The decision by Fannie Mae to modernize credit score requirements is a clear signal that the mortgage industry is evolving. By moving away from the “lowest median score” rule and embracing an averaged approach, they are opening doors for homebuyers and investors who were previously unfairly penalized.
This change acknowledges that a mortgage is often a shared responsibility. It allows the strengths of one borrower to help bolster the profile of another, creating a more equitable path to financing. In a market where every basis point and every dollar matters, this update is a welcome relief for those looking to secure the lowest rates and most flexible terms available.
Whether you are planning to buy your first home, upgrade to a larger space, or add another rental property to your portfolio, the current conventional loan guidelines are designed to help you succeed. By understanding how your credit is viewed and how these scores are calculated, you can move forward with the confidence that you are getting the best deal possible for your unique situation.
