    Common Mortgage Mistakes to Avoid

    Mistakes That Can Cost You Big

    Even small missteps during the mortgage process can lead to delays, denials, or thousands in extra costs. Here's what to avoid.

    Before Applying

    Mistake #1: Not Checking Your Credit First

    Discover errors or issues before lenders do. Get your free reports from AnnualCreditReport.com at least 3-6 months before applying.

    Mistake #2: Making Major Purchases

    That new car or furniture set can tank your debt-to-income ratio. Wait until after closing for big purchases.

    Mistake #3: Only Talking to One Lender

    Shopping around can save you 0.5% or more on your rate—that's tens of thousands over the life of your loan.

    During the Process

    Mistake #4: Changing Jobs

    Lenders want to see stable employment. If you must change jobs, stay in the same field and don't go from salary to commission.

    Mistake #5: Moving Money Around

    Large deposits or transfers raise red flags. Keep funds in one place and document any necessary moves.

    Mistake #6: Opening New Credit

    Even small credit inquiries can impact your approval. Don't apply for new cards, increase credit limits, or co-sign for anyone.

    Mistake #7: Ignoring the Loan Estimate

    This document shows your expected costs. Review it carefully and question anything that seems off.

    At Closing

    Mistake #8: Not Doing a Final Walk-Through

    Ensure the home is in the agreed condition and any negotiated repairs are complete.

    Mistake #9: Not Reading Before Signing

    Yes, there's a lot of paperwork. But signing something you don't understand can have serious consequences.

    Mistake #10: Forgetting About Reserves

    Don't drain your savings for the down payment. Keep 3-6 months of expenses as an emergency fund.

    After Closing

    Mistake #11: Skipping the First Payment

    Your first payment date might be 30-60 days out, but set up payment immediately to avoid any confusion.

    Mistake #12: Not Filing the Deed

    Ensure your closing attorney or title company properly records the deed with your county.

    Frequently Asked Questions

    What if I already made one of these mistakes?

    Don't panic. Many issues can be resolved with documentation and explanation. Be upfront with your lender about any concerns.

    Can a lender deny me after pre-approval?

    Yes. Pre-approval isn't final approval. Maintain your financial status quo until you have the keys.
