Once you’re under contract, your finances need to stay exactly as they were when you were approved. Even small changes can delay or completely kill a deal.

Here are the most common mistakes.

1. DO NOT change jobs or become self-employed.

   • Even if your income is higher. Even if it seems like a better move. Lenders need consistency until after closing.

2. DO NOT buy a car, truck or van unless you plan to live in it.

   • If it requires a payment or financing, it changes your debt and can change your approval.

3. DO NOT use your credit card needlessly or fall behind or payments.

   • This includes store cards, new credit cards, or “just checking your options.”

4. DO NOT use your credit cards more than usual

   • Higher balances can change your credit score and your loan terms.

5. DO NOT spend the money you have saved for closing

   • Even if you plan to replace it. The lender will check again.

6. DO NOT move large amounts of money between accounts

   • Lenders need to be able to clearly track where your money came from.

7. DO NOT make large deposits without talking to your lender first

   • If it is not payroll, it will need to be documented.

8. DO NOT change bank accounts

   • This creates more paperwork and more chances for delays.

9. DO NOT co-sign for anyone.

   • Even if you are “not really responsible for the payment.” On paper, you are.

10. DO NOT buy anything until after you close

    • If it can wait a week, it should wait.

The simple rule

If it affects your money, your credit, or your job, do not touch it without talking to your lender first.

And if you’re not sure, ask. It is always easier to prevent a problem than fix one right before closing.
