Before approving your loan, lenders primarily check your monthly debt compared to your gross income, followed by your credit score, steady job history, and down payment funds. Lenders want proof that you can pay them back on time. If your debt takes up too much of your income, they will reject your application even with a clean credit file.
What lenders check first
Pull your free credit files from Equifax, Experian, and TransUnion to verify that your record shows no late payments or errors.
Calculate your debt-to-income ratio by dividing your total monthly debt payments by your gross pre-tax income, keeping it at or below 43 percent.
Collect your last 30 consecutive days of paystubs and your last two full years of W-2 tax forms to prove steady earnings.
Gather two consecutive months of complete bank statements to prove your down payment funds didn't come from an undisclosed personal loan.
Keep your existing job and hold off on applying for new credit cards until after your loan closes.
Why lenders focus on debt ratios
Banks make money from interest, but they lose money when you default. A lender looks at your debt-to-income (DTI) ratio because income alone doesn't show what you have left at the end of the month. A high earner with massive student loans, auto leases, and credit card balances poses a bigger default risk than a modest earner with zero revolving balances.
The primary limit for many conventional mortgages is set by the Consumer Financial Protection Bureau debt-to-income rule, which establishes 43 percent as a standard ceiling for a Qualified Mortgage. Beyond this number, data shows borrowers struggle to make payments when unexpected expenses strike.
Lenders also review your credit history to see your payment habits. They check for collections, late notices, and public records. If you show a pattern of missed payments within the last 24 months, underwriters view you as risky. Your job stability provides the final layer of safety: lenders want to see at least two continuous years in the same field. This guide isn't for borrowers seeking hard-money loans or unsecured payday advances, which rely on asset equity or immediate paychecks rather than standard underwriting files.
When the answer is different
Different lending programs rely on different underwriting limits depending on the risk they take.
Situation | What changes | What to do instead |
|---|---|---|
Self-employed borrower | W-2 forms unavailable | Provide two years of full tax returns |
Applying for FHA loan | Lower credit score allowed | Accept mandatory mortgage insurance premiums |
High student loan debt | DTI calculation jumps | Switch to an income-driven repayment plan |
Recent job change | Income history resets | Show an offer letter in the same field |
Large cash gift used | Down payment origin unverified | Provide a signed donor gift letter |
Variable commission income | Base salary uncertain | Average earnings over past 24 months |
How to do it properly
Pull your credit reports from all three major bureaus to confirm your score meets the minimum required for your specific loan type.
Calculate your front-end and back-end debt-to-income ratios using your gross monthly income, verifying the total debt stays at or under 43 percent.
Save your recent federal tax returns and W-2
Download 60 days of complete bank statements, including all numbered pages, to verify you have enough cash to cover the closing costs.
Identify every single deposit over 50 percent of your monthly income on those statements, gathering written receipts or gift letters to explain them.
Submit your complete loan package to the underwriter without opening any new credit lines, keeping your balances static until the final closing.
The mistakes that ruin it
Financing a car or furniture before closing lowers your credit score and pushes your debt ratio over the legal limit.
Moving unverified cash into your bank account triggers money-laundering flags and forces underwriters to freeze your loan file.
Quitting your job or switching to an independent contractor role resets your employment clock and voids your conditional approval.
Missing a single credit card payment during underwriting adds a recent delinquency to your file, causing automatic loan denial.
Frequently asked questions
Can you get approved with bad credit?
Yes, you can secure an FHA-backed mortgage with a credit score down to 580 while putting down 3.5 percent. However, a lower score means higher interest rates and mandatory insurance costs. You trade a lower barrier to entry for higher lifetime payments.
Why do lenders ask for two months of bank statements?
Lenders ask for two months of statements to source your funds and confirm your down payment doesn't come from borrowed money. They look for regular payroll deposits and check that you haven't received large, unexplained cash transfers from outside accounts.
How long does loan underwriting usually take?
Underwriting usually takes two to three weeks for a standard home purchase, though complex files with self-employment income can take over 30 days. You can speed up the process by sending requested tax documents and bank statements within 24 hours of your loan officer's request.
Is it safe to change jobs while applying?
No, it isn't safe to change jobs while your loan is processing, especially if you move from a salary to commission or contract work. If you must switch, stay in the exact same field and get a fully executed offer letter confirming your new guaranteed base salary.
What happens if you get a large cash gift?
Your lender requires a signed gift letter from the donor stating that the money is an absolute gift and not a loan. You must also show a paper trail displaying the funds leaving the donor's bank account and entering your own.
Does closing old credit cards hurt your approval?
Yes, closing old credit cards hurts your application by reducing your total available credit and shortening your average credit age. This action spikes your credit utilization ratio overnight, which often drops your score right before your lender pulls their final credit report.
Take a close look at your bank statements tonight and see what you can trim. Even paying down a small credit card balance or holding off on big buys can make a huge difference. You'll feel much more confident when you finally sit down with a loan officer.
