7 Ways to Improve Your Credit Score Before Applying for a Mortgage (Including What's New in 2026)

Your credit score is one of the most important factors in your mortgage approval — and it just got more complex in 2026. Here are 7 strategies to strengthen your score, plus what the new FICO 10T and BNPL rules mean for Georgia buyers. (6 min. read)

If you're thinking about buying a home in the next 6-12 months, your credit score is one of the most important things you can be working on right now. It doesn't just determine whether you qualify — it directly affects your interest rate, which affects your monthly payment for the entire life of the loan.

Even a 20-point improvement in your credit score can potentially save you tens of thousands of dollars over a 30-year mortgage. That's a return on effort most people don't realize is available to them.

When to Start Prepping Your Credit

Let's be honest for a minute — most people don't want to look at their credit history. It's uncomfortable. Given the choice between a credit review and a trip to the dentist, the dentist usually wins.

We get it. Credit feels personal. Nobody wants to sit down and confront every past mistake, missed payment, or account they forgot about. It's easier to avoid it and hope for the best when it's time to buy a home.

Here's the thing though: waiting doesn't fix credit. And unlike a cavity, credit doesn't cause pain right up until the moment it matters most — and then it costs you thousands.

The good news is you don't have to figure it out alone. And there's a lot you can do in just one week that puts you in a completely different position. We layout your winning step-by-step strategy  below. 👇

First: Here's What Every Georgia Borrower Should Know

Before we get to the strategies, let's cover what's actually new in 2026— because the rules have changed and most consumers haven't caught up yet.

FICO 10T and VantageScore 4.0 are being adopted for mortgage lending. In April 2026, HUD and the FHFA announced plans to modernize credit scoring for federally-backed mortgages. FHA loans will move to FICO 10T and VantageScore 4.0, while Fannie Mae and Freddie Mac have already begun using VantageScore 4.0. This is one of the biggest changes in mortgage credit scoring in years.

These new models consider your credit behavior over time — not just a snapshot. FICO 10T specifically looks at your credit patterns over the past two years, not just where your score sits today. That means consistent habits matter more than quick fixes. If you've been steadily paying down debt and using credit responsibly, these models reward that behavior.

Buy Now Pay Later (BNPL) data is now being included. Starting in fall 2025, FICO launched FICO Score 10 BNPL and FICO Score 10T BNPL — the first scores to include BNPL data. Services like Affirm, Klarna, and Afterpay are now visible on credit reports. This can help borrowers who use BNPL responsibly and hurt those who don't.

Now let's get into what you can actually do about it.  

7 Ways to Improve Your Credit Score 

Before Applying for a Mortgage


1. Check Your Credit Report for Errors First

Before spending time trying to raise your score, make sure the score you have is accurate.

Studies have consistently shown that a significant percentage of credit reports contain errors — outdated accounts, incorrect balances, accounts that don't belong to you, or negative items that should have been removed. Any of those can be dragging your score down unfairly.

Correcting a single error can sometimes move your score 20-50 points overnight. This is the highest-return, lowest-effort step you can take.


2. Pay Down Credit Card Balances — But Don't Close the Accounts

Your credit utilization ratio — how much of your available credit you're using — is one of the biggest factors in your score. Most experts recommend keeping utilization under 30%, and ideally under 10% for the strongest scores.

Here's a common mistake we see: borrowers pay off a credit card and then close the account. That reduces their total available credit, which actually increases their utilization ratio on remaining balances and can hurt their score.

A pro tip most people don't know: paying your credit card mid-cycle — before the statement closes — can lower the balance reported to the bureaus, boosting your score even without changing your spending habits.


3. Don't Open New Credit Lines Right Before Applying

Every new credit application creates a hard inquiry on your credit report, which can temporarily lower your score. New accounts also lower the average age of your credit — another scoring factor. If you must open new credit, do it early in your prep timeline — not right before applying.


4. Understand How Buy-Now-Pay-Later (BNPL) Affects Your Score

This is one of the biggest changes for 2026. Buy Now Pay Later services like Affirm, Klarna, and Afterpay used to be invisible on credit reports. That's no longer the case. With FICO's new BNPL scoring models rolling out, your BNPL activity is now being factored into your credit picture.

    Before applying for a mortgage, consider:

    • Paying off any active BNPL balances
    • Avoiding new BNPL purchases in the 6 months before applying

    5. Ask About Alternative Credit Data if You Have a Thin File

    If you're a first-time buyer with limited traditional credit history — for example, you've always paid rent on time but never had a credit card — you may benefit from newer scoring models that consider alternative data.

    VantageScore 4.0 can now factor in:

    • Rent payment history
    • Utility payments
    • Telecom (phone) payments

    We would be happy to talk about whether an alternative credit data program makes sense for your situation.


    6. Keep Your Oldest Accounts Open

    The length of your credit history matters. Older accounts contribute positively to your score — even if you don't use them regularly. Some borrowers close old accounts thinking it "simplifies" their finances. In credit scoring terms, they've just handed themselves a lower score.

    The rule of thumb:

    • Don't close your oldest credit card, even if you don't use it
    • If a card has an annual fee you don't want to pay, ask the issuer to downgrade you to a no-fee version rather than closing the account
    • If you have to close an account, close a newer one — not an older one

    7. Pay All Bills On Time — Every Time

    This one sounds obvious, but it's the most important factor of all. Payment history is roughly 35% of your FICO score — more than any other single factor. However if you've had late payments in the past, know that their impact decreases over time. Consistent on-time payments going forward rebuilds your score.

    You don't need 6 months to see progress. Here's what you can do in the next 7 days to meaningfully improve your credit picture:

    Your '1 Week' Strategy - That Moves the Needle 

    Day 1-2: Pull your free reports from all three bureaus

    Mark or highlight errors on your credit reports, such as— outdated accounts, incorrect balances, or accounts that don't belong to you. Remember, most people find this part very uncomfortable and typically surprised by erroneous information


    Go to annualcreditreport.com and download all three reports (Experian, Transunion, Equifax). Each credit report usually has differing information i.e. the information on your Experian report might be a little different than what's reported on your Transunion report.

    Day 3: Get a professional credit review + your credit score

    You can pull your own FICO score from apps like Credit Karma or your bank — but here's the catch: those consumer scores are often different from the FICO scores mortgage lenders actually use. To know your real mortgage-qualifying score, you need a mortgage professional to pull it.


     At Stone Oak Mortgage, we do this at no cost and no obligation. We look at your full credit picture and tell you honestly what to focus on, what to leave alone, and what quick wins are available for your specific situation.

    Day 4-5: Target the highest-impact credit account first 

    We will help you identify which single account, if paid down or corrected, would move your score the most. Sometimes it's a maxed-out credit card. Sometimes it's a collection that can be negotiated. Sometimes it's simply disputing an error. This targeted approach is far more effective than trying to fix everything at once or guessing.

    Day 6-7: Take action on that account 

    Make the payment. File the dispute. Call the collector. Whatever the specific action is — take it now, not next month.

     The BEST 1st STEP is knowing where you actually stand — and that starts with a conversation.
