🚫 What Not to Do Before Mortgage Approval
❌ Critical Mistakes That Can Kill Your Approval
These actions can derail your mortgage approval, even after you've been pre-approved:
💳 Opening New Credit Accounts
New credit cards, auto loans, or personal loans change your credit score and debt-to-income ratio. Even store credit cards for furniture can cause problems.
💰 Making Large Purchases
Avoid buying cars, furniture, or other big-ticket items. Lenders verify your financial status just before closing and large purchases can change your qualification.
💸 Large Cash Deposits
Deposits over $500 require documentation. Unexplained deposits raise red flags about income source and can delay or deny approval.
💼 Changing Jobs
Job changes require re-verification of employment and income. If you must change jobs, notify your lender immediately and provide documentation.
🏦 Moving Money Between Accounts
Large transfers between accounts require explanations. Keep money stable in the accounts you've already documented.
📋 Ignoring Lender Requests
Respond to lender requests within 24-48 hours. Delays in providing requested documentation can cause your approval to expire.
