Getting pre-approved can feel like you’re in the clear. You’ve submitted your documents, your credit’s been reviewed, and a lender has given you the green light to start house hunting.
But here’s something many buyers don’t realize – your loan isn’t fully approved until the very end of the process.
That means certain financial moves, even ones that seem harmless, can derail your mortgage before closing day.
If you’re under contract or planning to be soon, here are three things that can kill your mortgage approval.
1. Changing Jobs at the Wrong Time
A new job can be exciting. A promotion can feel like a win. But during a mortgage process, employment stability matters.
Lenders verify your employment before closing. If you switch jobs in the middle of the process, especially if you move from salaried to commission-based income, it can create delays or even force the lender to re-evaluate your approval.
This doesn’t mean you can never change jobs. It just means timing matters. If a job change is unavoidable, talk to your lender before making the move so you understand how it may affect your loan.
Stability is your friend during underwriting.
2. Taking on New Debt
This is one of the most common approval killers.
Financing a new car. Opening a new credit card for furniture. Co-signing on a loan for a family member. Even a large increase in credit card balances can shift your debt-to-income ratio enough to cause problems.
Remember, your approval was based on your financial profile at the time you applied. New debt changes that profile.
Even if the monthly payment seems small, lenders must include it in your qualification calculations. Sometimes that small change is enough to push you outside approved limits.
Until your loan has officially closed, it’s best to avoid any new credit activity.
3. Moving Money Around Without Documentation
Large deposits or unexplained transfers can raise red flags.
Lenders are required to source funds used for your down payment and closing costs. If a significant amount of money suddenly appears in your account and there’s no clear paper trail, underwriting will pause until it’s documented.
Gift funds from family are allowed in many cases – but they must be properly documented. Selling an asset is fine – but you need proof.
Keeping your finances steady and transparent during the process prevents unnecessary stress.
A Bonus Reminder – Keep Paying Everything On Time
It sounds obvious, but missed or late payments during the mortgage process can seriously damage your approval.
Lenders often re-check your credit before closing. A new late payment can lower your score or trigger additional review.
From application to closing day, treat your credit like it’s under a microscope – because it is.
The Bottom Line
The mortgage process doesn’t end at pre-approval. It ends at closing.
From the moment you apply until you get the keys, your financial picture needs to remain stable. No big changes. No new debt. No unexplained deposits.
