You’ve found the house. It has the perfect kitchen island, the backyard is big enough for a golden retriever, and it’s in a school district that actually looks good on paper. You’re ready to sign, but then your mortgage officer calls with news that feels like a gut punch: your credit score isn’t quite where it needs to be. Suddenly, that "dream home" feels a lot more like a "maybe someday" home.
At Maya Team Inc., we see this happen all the time. The frustrating part? Most of the time, the "bad credit" isn't because you're irresponsible: it's because of small, silly mistakes that are surprisingly easy to fix once you know they exist.
If you're planning to buy a home in the next 6 to 12 months, your credit score is your most valuable asset. It determines whether you get approved and, more importantly, how much interest you'll pay over the next 30 years. Let’s dive into the seven most common credit mistakes and how you can flip the script before you head to the closing table.
1. The "Life Happens" Late Payment
The Mistake: You forgot about that $15 utility bill or a small credit card payment while you were on vacation. It was only 30 days late, so it’s no big deal, right?
The Reality: Wrong. Your payment history accounts for a whopping 35% of your FICO score. A single 30-day late payment can knock 50 to 100 points off a high credit score instantly. Lenders view late payments as a red flag that you might struggle with a mortgage.
The Fix:
- Go Automatic: Set every single bill to at least the "minimum payment" auto-pay. You can always pay more manually, but this ensures you never miss a deadline.
- The Goodwill Letter: If you have a long history of on-time payments, call the creditor and ask for a "goodwill adjustment" to remove the late mark. It doesn’t always work, but it’s worth the 10-minute phone call.

2. Maxing Out Your Cards (Even if You Pay Them Off)
The Mistake: You use your credit card for everything to earn points, and you pay it off in full every month. However, your balance is often near the limit when the statement closes.
The Reality: Credit Utilization makes up 30% of your score. If you have a $5,000 limit and your balance is $4,500 when the bank reports to the credit bureau, your utilization is 90%. Even if you pay it off two days later, the "snapshot" taken by the credit bureau shows you are over-extended.
The Fix:
- The 30% Rule: Keep your balances below 30% of your limit at all times. For the best scores, aim for under 10%.
- Pay Early: Find out your "statement closing date" (not the due date) and pay your balance down before that day. This ensures a low balance is reported to the bureaus.
3. Closing Old Credit Card Accounts
The Mistake: You finally paid off that old card from college and decided to close the account to "simplify" your life.
The Reality: This is one of the most common mistakes first-time buyers make. Length of credit history is 15% of your score. When you close an old account, you shorten your average credit age and reduce your total available credit, which can unintentionally spike your utilization ratio.
The Fix:
- Keep It Open: If there is no annual fee, leave the card open. Put a small recurring subscription (like Netflix) on it and set it to auto-pay.
- Hide the Plastic: If you’re tempted to spend, literally hide the card or put it in a bowl of water in the freezer. Just don't close the account!

4. Applying for Every "Retail Discount" in Sight
The Mistake: You’re at the checkout at a big-box store, and the cashier offers 20% off if you open a store card. You figure, "Why not save $40?"
The Reality: Every time you apply for credit, a "hard inquiry" hit happens. While one inquiry might only drop your score by a few points, multiple inquiries in a short period tell lenders you are desperate for credit. This is a major "no-no" when you're in the middle of a mortgage application.
The Fix:
- The "Buying Ban": If you are within six months of buying a home, stop applying for anything: no new cars, no furniture financing, and definitely no retail cards.
- Rate Shopping Exception: When shopping for a mortgage, all inquiries within a 14-to-45-day window are usually treated as a single inquiry. So, shop for your lender all at once!
5. Ignoring Errors on Your Credit Report
The Mistake: Assuming the credit bureaus have everything right.
The Reality: Statistics show that roughly 1 in 4 credit reports contains a serious error that could affect a lending decision. This could be a debt that isn't yours, an incorrect balance, or a "late payment" that you actually paid on time.
The Fix:
- Check for Free: Go to AnnualCreditReport.com and pull your reports from all three bureaus (Equifax, Experian, and TransUnion).
- Dispute Everything Wrong: If you find an error, dispute it online immediately. The bureaus have 30 days to investigate. Removing one "false" late payment can skyrocket your score overnight.

6. Only Making Minimum Payments
The Mistake: You’re paying your bills on time, but only the minimum amount requested.
The Reality: While this protects your "Payment History," it destroys your Debt-to-Income (DTI) ratio. Lenders look at how much of your monthly income goes toward debt. If your DTI is too high, you won't qualify for programs like CalHFA or FHA loans, even with a decent credit score.
The Fix:
- The Snowball Method: Focus on paying off the smallest balance first to gain momentum, then move to the next.
- DTI Focus: Talk to your Maya Team Inc. advisor about where your DTI needs to be. Sometimes, paying off a $500 credit card is more effective for your mortgage approval than saving an extra $500 for your down payment.
7. Co-signing for Friends or Family
The Mistake: Your cousin needs a car, and you co-sign the loan to help them out. They promise to make all the payments.
The Reality: As far as a mortgage lender is concerned, that is your debt. If your cousin misses a payment, your credit gets hit. Even if they pay on time, that monthly payment is factored into your DTI, potentially lowering the amount of house you can afford.
The Fix:
- Just Say No: Until you have the keys to your own home and the mortgage is finalized, do not co-sign for anyone. It’s not being mean; it’s being smart about your financial future.

What if my credit still isn't "Perfect"?
Here is the good news: You don’t need a 800 score to buy a home.
Programs like FHA loans allow for scores as low as 580 (and sometimes lower with a higher down payment). If you’re a first-time buyer in California, the CalHFA MyHome Assistance program can help with your down payment, but it does have specific credit score requirements (usually around 640-660 depending on the loan type).
We also work with products like Fannie Mae’s non-traditional credit options, which look at things like your history of paying rent and utilities on time if you don't have a deep credit file.

Your Pre-Purchase Checklist
Before you start browsing Zillow, do these three things:
- Get a professional credit review. Don't just rely on the "free" apps; they often use different scoring models than mortgage lenders.
- Organize your documents. Have your last two years of tax returns and 30 days of pay stubs ready.
- Talk to an expert. A quick consultation can save you thousands of dollars in interest.
