How do I improve my chances of getting approved for a mortgage?

The most effective ways to improve mortgage approval odds are raising your credit score, lowering your debt-to-income ratio, saving a larger down payment, and maintaining stable employment history for at least 2 years before applying.

Mortgage lenders evaluate four primary factors: credit score, debt-to-income ratio (DTI), down payment, and employment/income stability. Improving any one of these moves the needle; improving all four maximizes your rate and approval odds. The CFPB's mortgage approval guide is the most comprehensive free resource for understanding what lenders actually look at.

1. Raise your credit score

Credit score is the single variable with the most impact on both approval odds and rate. Going from 680 to 740 can mean 0.5–1% lower rate; going from 620 to 760 can mean 1.5–2%. The fastest legal ways to raise your score before applying: pay down credit card balances below 30% of credit limit (utilization has fast-moving impact); dispute any errors on your credit report; do not open new credit accounts in the 6–12 months before applying; and make 100% on-time payments. The CFPB's free credit guide covers all the levers.

2. Lower your debt-to-income ratio

DTI is total monthly debt ÷ gross monthly income. Most conventional lenders want total DTI under 43–45%. The fastest ways to lower DTI: pay off small consumer debts (a car with 6 months left, a credit card balance); avoid taking on new debt before applying; and increase income through a raise, documented side income, or part-time work before applying. Don't close paid-off credit cards — closing them can raise utilization and hurt your credit score.

3. Save a larger down payment

A larger down payment reduces your loan-to-value ratio (LTV), which directly reduces lender risk. At 20%+ down, you avoid PMI entirely. At 10–19% down, you qualify for lower PMI rates. At 3–5% down, you need strong credit and DTI to compensate for the higher LTV. Every additional 5% you can put down makes the file cleaner — start saving early and use a high-yield savings account to grow the fund.

4. Protect your employment history

Lenders want 2 years of employment history at the same employer or in the same field. Job changes within the same industry are usually fine if income is stable or increasing. Switching industries, going self-employed, or switching from a salaried to a commission-based role can complicate approval. If any of these apply, delay the application by 12–24 months if possible, or be prepared to document income thoroughly.

What to avoid in the months before applying

• Don't make large, unexplained cash deposits — lenders trace down payment funds for sourcing.
• Don't open new credit accounts or take on new debt (auto loan, personal loan, new credit card).
• Don't co-sign a loan for someone else — it appears on your credit and increases DTI.
• Don't quit your job — even a better job offer should ideally be held until after closing.
• Don't make large purchases on credit (furniture, appliances) before closing.

• The CFPB defines debt-to-income ratio as total monthly debt payments divided by gross monthly income. A DTI above 43% is considered a threshold for 'qualified mortgages' under CFPB rules. — CFPB — Debt-to-Income Ratio
• Paying down revolving credit card balances is one of the fastest ways to improve your credit score — utilization (balance ÷ limit) is recalculated every billing cycle. — CFPB — How to Improve Your Credit

Key takeaways

• Raise credit score: pay down card balances below 30% utilization, dispute errors, pay on time.
• Lower DTI: pay off small debts before applying; avoid new debt in the 6 months before applying.
• Save more down payment: reduces LTV, eliminates PMI at 20%, and compensates for weaker credit.
• Protect employment history: 2 stable years in the same field is the standard; job switches can complicate the file.
• Avoid new debt, large purchases, job changes, or unexplained cash deposits in the 3–6 months before applying.
