Short Answer: Most credit score mistakes involve missing payments, high credit card balances (over thirty percent utilization), and applying for new debt right before a mortgage. To fix them, you must pull your reports from all three bureaus, dispute errors, bring past-due accounts current, and stop opening new credit lines at least six months before you plan to buy a home.


Buying your first home is one of the most exciting milestones in life, but it can also be one of the most stressful if your credit score isn’t where it needs to be. At Maya Team Inc., we’ve helped thousands of families navigate the complex world of real estate and mortgage loans. We know that a few points on your credit score can be the difference between a "yes" and a "no," or between a high interest rate and a monthly payment that fits comfortably in your budget.

Your credit score is essentially your financial reputation. Lenders use it to predict how likely you are to pay back a loan. If you’re making these common mistakes, you might be unintentionally sabotaging your path to homeownership.

Here are the seven biggest mistakes we see, and more importantly, how you can fix them starting today.

1. Not Checking Your Credit Report Regularly

Many people assume their credit is fine because they pay their bills on time. However, a federal study found that about one in four consumers had errors on their reports that could negatively affect their scores. If you don't look at your reports from Equifax, Experian, and TransUnion, you won't know if there are fraudulent accounts or misreported late payments dragging you down.

How to fix it:

  • Visit AnnualCreditReport.com to get your free reports.
  • Review every line for accuracy.
  • If you find an error, dispute it immediately with the credit bureau. This process can take thirty to sixty days, so do this well before you start house hunting.

2. Making Late Payments (Even Just One!)

Payment history is the single largest factor in your FICO® Score, accounting for thirty-five percent of the total. Even a single thirty-day late payment can cause a significant drop in your score. For a mortgage lender, a recent late payment is a major red flag that suggests you might struggle with a new mortgage payment.

How to fix it:

  • Set up autopay for at least the minimum amount due on all your accounts.
  • If you missed a payment recently, bring the account current immediately. The "age" of the late payment matters: the further in the past it is, the less it hurts.
  • Contact the creditor and ask for a "goodwill adjustment" if you have a long history of on-time payments.

3. Maxing Out Your Credit Cards

You might think that as long as you pay the minimum, a high balance is fine. In reality, your credit utilization ratio: the amount of credit you’re using compared to your limits: is the second most important factor in your score. If you have a credit card with a limit of one thousand dollars and you carry a balance of nine hundred dollars, your utilization is ninety percent. Lenders prefer to see this under thirty percent.

How to fix it:

  • Aim to keep balances below thirty percent of the limit on every single card.
  • If you have extra cash, pay down the cards with the highest utilization first.
  • Avoid using your cards for large purchases while you are in the mortgage process.

4. Applying for New Credit Before Buying a Home

Every time you apply for a credit card, auto loan, or personal loan, the lender performs a "hard inquiry." This can shave several points off your score. More importantly, it changes your Debt-to-Income (DTI) ratio. If you buy a new car with a five hundred dollar monthly payment right before applying for a mortgage, you might no longer qualify for the home loan amount you wanted.

How to fix it:

  • Put a "freeze" on new spending. Do not open any new accounts for at least six months before your mortgage application.
  • Wait until after you have the keys to your new home before buying furniture or a car on credit.

5. Closing Old Credit Card Accounts

It seems logical: if you don’t use a card, you should close it. However, closing an old account can actually lower your score. It reduces the average age of your credit history and decreases your total available credit, which instantly increases your utilization ratio.

How to fix it:

  • Keep your oldest accounts open, even if you don't use them frequently.
  • Use the card once every few months for a small purchase (like a ten dollar lunch) and pay it off immediately to keep the account active.

6. Having a "Thin" Credit File

Some people avoid credit altogether because they don't want to be in debt. While staying debt-free is a great goal, mortgage lenders need to see a track record of responsible borrowing. If you have no credit history, you have no credit score, which makes it very difficult for traditional lenders to approve you for a mortgage.

How to fix it:

  • If you have no credit, consider a secured credit card where you provide a deposit of, for example, five hundred dollars, and that becomes your limit.
  • Ensure the card issuer reports to all three major bureaus.
  • Become an authorized user on a family member's account if they have a long history of perfect payments.

7. Ignoring Your Debt-to-Income Ratio

While your credit score tells a lender if you will pay, your Debt-to-Income (DTI) ratio tells them if you can pay. If you have a high credit score but your monthly debt obligations (car loans, student loans, credit card minimums) take up too much of your gross monthly income, you won't qualify for the loan.

How to fix it:

  • Calculate your DTI by adding up all your monthly debt payments and dividing by your gross monthly income.
  • Lenders generally want to see a total DTI (including your new mortgage) below forty-three to fifty percent, depending on the loan program.
  • Focus on paying off small balance debts to "free up" monthly cash flow.

What You Should Do Right Now: A Checklist

If you are planning to buy your first home in the next six to twelve months, follow this simple checklist to get your credit mortgage-ready:

  • Pull your reports: Check for errors at AnnualCreditReport.com.
  • Clean up errors: Dispute anything that isn't yours.
  • Lower utilization: Get every card below thirty percent of its limit.
  • No new debt: Stop applying for cards or loans.
  • Stay current: Never miss a payment date.
  • Gather your docs: Have two years of tax returns and W2s ready.
