Your financial decisions in the weeks before and during a mortgage application carry more weight than most buyers expect. A few smart habits — and avoiding a handful of common mistakes — can mean the difference between a smooth closing and an unexpected delay.
What to Keep Doing
Start with pre-approval. Getting pre-approved before you shop gives you a realistic budget and signals to sellers that you're a serious buyer. It also surfaces any credit or income questions early, while there's still time to address them.
Stay consistent with your income and employment. Lenders want to see stability. If you're considering a job change, try to hold off until after your loan closes. Self-employed? Keep your documentation organized — tax returns, profit-and-loss statements, and bank records will likely all be requested.
Pay your bills on time. Your payment history is one of the most influential pieces of your credit profile. Keep up with every account — not just credit cards, but utilities, subscriptions, and any personal loans.
Build your paperwork file early. You'll need recent pay stubs, W-2s, bank statements, and tax returns. Having these ready speeds up the process and reduces back-and-forth.
What to Avoid
Large purchases on credit. Buying furniture, a car, or electronics before closing can raise your debt-to-income ratio and jeopardize your approval — even after you've received a conditional commitment.
Opening or closing credit accounts. New credit inquiries can temporarily lower your score. Closing old accounts can shorten your credit history. Both may raise flags during underwriting.
Co-signing for someone else. Even if you never make a payment, co-signing adds to your debt obligations. Lenders count it against your ability to carry a mortgage.
Unexplained financial moves. Large transfers between accounts or sudden deposits can slow down underwriting while lenders verify the source. Keep your banking activity routine and document any gifts or unusual transactions.
Why This Matters
Mortgage underwriting looks at a snapshot of your financial life — and it's a snapshot that can change right up until closing day. Lenders sometimes run a final credit check before funding, so consistency matters throughout the entire process.
If you're unsure about a specific decision — a new job, a large purchase, a financial gift from family — ask your mortgage advisor first. It takes a minute and can save a lot of headaches.
