Qualifying for a mortgage loan hinges on two critical factors: your credit score and your income. Lenders use these metrics to assess whether you’ll reliably repay borrowed money. Understanding exactly what lenders want—and how to improve your position before applying—gives you a real advantage when pursuing homeownership.
Understanding Credit Score Requirements
Your credit score is a three-digit number that tells lenders how responsibly you’ve managed credit in the past. It’s built on five main factors: payment history (35%), credit utilization (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%).
Most conventional mortgage lenders require a minimum credit score of 620, but this is the bare minimum. Here’s what different score ranges typically mean:
- 620-669: Possible to qualify, but expect higher interest rates and stricter requirements
- 670-739: Good credit; you’ll qualify for competitive rates
- 740+: Excellent credit; you’ll access the best available rates
FHA loans (backed by the Federal Housing Administration) are more flexible, sometimes accepting scores as low as 580, though 620+ still gets you better terms. VA loans and USDA loans have similarly accessible credit requirements for eligible borrowers.
If your credit score is below 620, take time before applying to build it up. Pay all bills on time, reduce credit card balances (aim for under 30% utilization), and avoid opening new accounts right before applying for a mortgage.
Income Requirements and Documentation
Lenders need to verify you have stable income that’s sufficient to cover your mortgage payment plus other obligations. The key metric is your debt-to-income ratio (DTI), which compares your monthly debt payments to your gross monthly income.
Most conventional lenders cap DTI at 43%, meaning your total monthly debts can’t exceed 43% of your gross income. Some lenders go as high as 50% DTI for well-qualified borrowers. For example, if you earn $6,000 gross monthly, a 43% DTI allows up to $2,580 in monthly debt payments, including your new mortgage.
To calculate DTI, add up all monthly debt payments:
- Current mortgage or rent
- Car loans and leases
- Student loans
- Credit card minimum payments
- Personal loans
- Child support or alimony
Lenders verify income through multiple documents:
- W-2 employees: Two years of recent pay stubs, W-2s, and tax returns
- Self-employed: Two years of business tax returns and personal tax returns
- Commission income: Two-year average, verified through tax returns
- Bonus income: Two-year history; sometimes requires employment letter confirming continuation
- Rental income: Lease agreements, tax returns, and bank statements showing deposits
Lenders typically require tax returns because they show your actual income rather than just what you claim on pay stubs. If you’re recently self-employed, you may face stricter scrutiny or need to wait until you have two full years of returns.
The Complete Qualification Picture
Credit score and income are foundational, but lenders evaluate several additional factors to make their decision.
Down Payment: The size of your down payment affects qualification. A 20% down payment is considered standard and eliminates mortgage insurance requirements. However, you can qualify with as little as 3% down on conventional loans or just 3.5% on FHA loans. Smaller down payments mean higher risk in the lender’s eyes, so they may require better credit or income documentation.
Employment History: Lenders want to see stable employment. A two-year history in the same field is standard. Job changes within your industry are usually fine; lenders worry more about unexplained gaps or frequent job-hopping that suggests instability.
Savings and Assets: Your reserves matter. After accounting for down payment and closing costs, do you have savings left over? Lenders view this as a safety net. You might need to show 2-6 months of mortgage payments in reserves, depending on the loan program and your circumstances.
Bankruptcy and Foreclosure History: These don’t disqualify you forever. Conventional loans typically require seven years since a discharge or dismissal. FHA loans sometimes allow qualification after three years with strong compensating factors. Recent late payments hurt more than older ones.
The best approach is to enter the mortgage application process in the strongest possible position. Before you apply, review your credit report for errors, pay down high credit card balances, ensure your income documentation is organized, and avoid major purchases or new debt that would raise your DTI.

Frequently Asked Questions
What credit score do I really need to get a mortgage?
Technically, 620 is the minimum for conventional loans, but you’ll get significantly better interest rates at 740+. The difference between a 620 score and a 760 score could cost you tens of thousands in additional interest over 30 years. If you’re under 670, focus on improving your score before applying. Each 50-point improvement typically saves you about 0.5% in interest rate.
Can I get approved if I’m self-employed?
Yes, but it requires more documentation. Self-employed borrowers need two complete years of business and personal tax returns. Lenders average your income over two years, which can be challenging if your business is growing rapidly. They may average lower if your recent income is higher. Keep detailed records and consult with a lender early to understand their specific requirements.
How much does debt-to-income ratio actually matter?
It matters a lot. This single ratio determines whether you qualify at all, and it’s one of the few metrics completely within your control pre-application. If your DTI is above 43%, you have two paths: increase income or decrease debt. Paying down credit cards or eliminating a car loan before applying can make the difference between approval and denial.
