8 Ways to Blow Up Your Financing When Buying a Home

Congratulations! Your offer has been accepted, and you’re officially under contract. You may be excited to start packing boxes and planning your move, but if you’re obtaining a mortgage, the process isn’t over yet. Many buyers make mistakes during the loan approval process that can jeopardize their financing and put their home purchase at risk. Understanding these pitfalls is crucial to making it to the closing table without surprises.

In this guide, we’ll go over 8 ways homebuyers commonly blow up their financing and provide actionable tips on how to avoid these mistakes.

1. Job Changes

Lenders place a high priority on your employment and income history when evaluating your mortgage application. A change in your job status—such as switching jobs, reducing hours, or quitting altogether—can significantly affect your loan eligibility.

Why it matters:

• Mortgage lenders assess stability and consistent income to ensure you can repay the loan.

• A sudden change can trigger additional scrutiny or even disqualify you from your pre-approved loan.

Tip: Avoid changing jobs or reducing work hours until after your mortgage closes. If a change is unavoidable, communicate immediately with your lender. They may guide you on potential solutions to maintain your approval.

2. Big Expenses

It’s tempting to purchase furniture, appliances, or home decor before you move in, especially once your dream home is secured. However, large purchases during the loan approval process can negatively impact your debt-to-income ratio and creditworthiness.

Why it matters:

• Mortgage lenders continually reassess your finances during underwriting.

• Using your down payment funds or accumulating debt can lead to a loan denial.

Tip: Hold off on major purchases until after closing. Even if you intend to replenish funds before the move, lenders may still see the changes as a risk.

3. Additional Credit Checks

Your lender will pull your credit report to evaluate your financial health, but multiple inquiries from other lenders or financial institutions can hurt your credit score.

Why it matters:

• Multiple inquiries suggest to lenders that you are taking on new debt or are financially stretched.

• A lower credit score can impact your mortgage interest rate or loan eligibility.

Tip: Avoid applying for new credit cards, auto loans, or personal loans during the mortgage process. Only your mortgage lender should check your credit.

4. Increasing Credit Card Charges

It’s normal to use credit cards for everyday purchases, but increasing your balances during the mortgage approval process can signal risk to lenders.

Why it matters:

• Higher balances increase your debt-to-income ratio.

• This can reduce your qualifying mortgage amount or lead to a loan denial.

Tip: Pay down existing balances and avoid using credit for non-essential expenses until your mortgage closes.

5. Moving Money in Savings Accounts

Your savings account balance is a critical factor in mortgage underwriting. Lenders look at your financial reserves and require a documented “paper trail” for all funds.

Why it matters:

• Large withdrawals or transfers can raise questions about the source of your funds.

• Even planned deposits that aren’t documented can complicate the process.

Tip: Keep savings intact until after closing. If you must use funds, notify your lender and follow their guidance to avoid delays.

6. Large Deposits

Unexpected or large deposits into your bank account can also raise red flags. Lenders need to verify that your money comes from a legitimate source and that your financial profile hasn’t changed.

Why it matters:

• Undocumented deposits can trigger additional documentation requests or loan re-evaluation.

• This can delay closing or even result in denial.

Tip: If a deposit is unavoidable, speak with your lender first. They can advise you on how to properly document the funds.

7. Late Bill Payments

Even minor missed payments can have an impact during the mortgage process. Late payments may be reported immediately, affecting your credit score and the lender’s risk assessment.

Why it matters:

• On-time payments demonstrate financial responsibility and stability.

• Late payments can signal potential risk to your lender.

Tip: Set up automatic payments or reminders to ensure all bills are paid on time. This includes utilities, credit cards, and loans.

---

8. Switching Banks

Changing your bank accounts during the loan approval process can create unnecessary complications. Lenders may need additional verification for new accounts, which can slow down or jeopardize the loan.

Why it matters:

• Any disruption in your financial accounts may require extra documentation.

• The lender may question the source of your funds or financial stability.

Tip: Avoid opening or moving accounts until after closing. If it’s unavoidable, inform your lender ahead of time and get guidance on how to proceed safely.
