Applying for a mortgage puts your financial life under a microscope. Even innocent-looking decisions—like buying new furniture or moving money between accounts—can trigger red flags for lenders. This guide highlights the top 10 mistakes homebuyers make during the mortgage process and provides expert tips from Brad and Karen Mattonen on how to keep your loan approval on track.”
Let’s connect and talk about the latest insights in the industry!

One often overlooked mistake in today’s market is failing to stay in constant communication with your agent and lender before making any financial shift. In California, lending requirements for 2026 have become even more stringent regarding ‘large gift deposits’ and side-income verification. If you are receiving help from family for your down payment, the paper trail must be perfect. At HomesInSDCounty, we provide our clients with a pre-closing ‘financial lockdown’ checklist. This ensures that your Debt-to-Income (DTI) ratio remains exactly where it was when you were pre-approved. Remember: the mortgage process isn’t over when you sign the contract—it’s over when the loan is funded and the deed is recorded.

  • Can I change jobs while my mortgage is in process? It is best to avoid changing jobs or industries until after your loan has closed. Lenders look for income stability, and a sudden change can force them to restart your approval process or deny the loan entirely.
  • Is it okay to make large purchases like furniture or a car before closing? No. Large purchases increase your debt-to-income (DTI) ratio and can cause a dip in your credit score, both of which may disqualify you from the mortgage you were originally approved for.
  • Why does my lender care about large deposits in my bank account? Lenders must document the source of all funds to prevent money laundering and ensure the money isn’t from an undisclosed loan. Always consult your mortgage advisor before moving large sums of money.
