How Do I Qualify for a Mortgage?

Understanding Credit Score Requirements, Income, Employment History, Debt-to-Income Ratio, and Key Documentation

Buying a home is one of the biggest financial milestones most people reach, but qualifying for a mortgage can feel overwhelming if you don’t understand what lenders look for. While different loan programs have their own rules, most lenders evaluate applicants using a core set of financial criteria: credit score, income stability, employment history, debt-to-income ratio, assets, and supporting documentation.

This guide breaks down each factor in detail so you know exactly what to expect and how to prepare.

1. Credit Score Requirements

Your credit score is one of the first—and most influential—items a lender reviews. It helps them judge how likely you are to repay your loan based on past borrowing behavior.

Typical Credit Score Minimums

Mortgage minimums vary by loan type:

• Conventional Loans:
  Typically require a 620+ credit score. Higher scores may qualify for better interest rates and lower private mortgage insurance (PMI) costs.

• FHA Loans:
  Backed by the Federal Housing Administration, FHA loans allow lower scores:

  • 580+ to qualify for a 3.5% down payment

  • 500–579 may qualify but require at least 10% down

• VA Loans (for eligible military borrowers):
  The VA does not set a minimum score, but most lenders look for 580–620+.

• USDA Loans (for rural, moderate-income borrowers):
  Typically require 640+ to use the automated approval system.

How Credit Scores Affect Approval and Rates

• Higher scores reduce borrowing costs and improve loan approval chances.

• Lower scores can lead to higher interest rates or require more documentation.

• Major negative marks—recent bankruptcies, foreclosures, or delinquencies—may require waiting periods before you can qualify again.

How to Improve Your Score Before Applying

• Pay down credit card balances

• Make on-time payments consistently

• Avoid opening new credit accounts close to your mortgage application

• Check your credit reports for errors and dispute inaccuracies

2. Income Requirements: How Much You Need to Earn

Lenders want to know your income is sufficient and reliable enough to cover monthly mortgage payments along with other financial obligations.

Types of Acceptable Income

Lenders typically count income that is stable, predictable, and likely to continue for at least three years. Examples include:

• Salary or hourly wages

• Overtime, bonuses, and commissions (with a two-year history)

• Self-employment income (two years of tax returns)

• Social Security income

• Disability benefits

• Pension or retirement distributions

• Alimony or child support (optional to disclose)

• Rental income

Income Consistency

Even if you earn enough money, lenders prefer consistency. Frequent job changes or fluctuating income may require additional documentation.

3. Employment History

Your employment background helps lenders evaluate financial stability and predict future earnings.

General Expectations

• Most lenders want to see two years of steady employment in the same field.

• Changing jobs is usually okay if you're staying in the same industry or moving to a higher-paying role.

• Gaps in employment may require an explanation, but they don’t automatically disqualify you.

Self-Employed Borrowers

If you're self-employed, lenders typically want:

• Two years of business and personal tax returns

• Profit and loss statements

• Business bank statements

Your income is often calculated as an average of the last 24 months, not current earnings alone.

4. Debt-to-Income Ratio (DTI)

Your DTI ratio measures how much of your monthly income goes toward debt payments. It’s one of the most important qualifying factors because it reflects your ability to handle new debt.

How DTI Is Calculated

There are two types:

1. Front-End DTI:
   Housing expenses only (mortgage, taxes, insurance)

2. Back-End DTI:
   All monthly debt obligations, including:

   • Credit card minimum payments

   • Car loans

   • Student loans

   • Personal loans

   • Existing housing payments

   • Court-ordered payments like child support

Formula:

Total Monthly Debt Payments / Gross Monthly Income × 100

Typical DTI Limits by Loan Type

• Conventional: Usually 43%–50% max

• FHA: Up to 57% with strong compensating factors

• VA: No fixed maximum, but lenders prefer 41%–50%

• USDA: Typically 41%–45%

Lower DTIs lead to better loan terms, but high DTIs can still be approved with strong credit or substantial savings.

How to Improve Your DTI

• Pay off or reduce balances on revolving debt

• Avoid taking on new loans before applying

• Increase income (overtime, new job, side income)

• Refinance high-interest debts

5. Assets and Down Payment Requirements

Lenders also look at your available assets because they confirm you have enough money not only for the down payment but also for closing costs and financial reserves.

Common Down Payment Guidelines

• Conventional:
  As low as 3% for first-time buyers
  5%–20% for most others

• FHA:
  3.5% with a credit score of 580+

• VA & USDA:
  0% down for eligible borrowers

Reserves (Cash Left After Closing)

Some loans require 1–6 months of mortgage payments in reserve, especially jumbo loans or borrowers with lower credit.

Acceptable Funds for Down Payment

• Savings and checking accounts

• Retirement accounts

• Gift funds from family (with a formal gift letter)

• Sale of personal property (with documentation)

Untraceable cash deposits are usually not allowed.

6. Property Requirements

The home itself must also qualify. Lenders ensure the property is sound and worth the purchase price.

Typical Requirements

• Appraisal confirming the home’s market value

• Home meets safety and habitability standards

• Title search confirming no legal issues with ownership

Government-backed loans (FHA, VA, USDA) have stricter property condition standards.

7. Other Documentation Lenders Require

When you apply for a mortgage, you’ll need to provide a detailed set of paperwork. Being prepared can speed up the approval process significantly.

Common Documents Include:

• Identification: Driver’s license or passport

• Proof of income:

  • Recent pay stubs

  • W-2 statements (last 2 years)

  • Tax returns (especially if self-employed)

• Bank statements:
  Usually the last two months for all accounts

• Asset documentation:
  Statements for retirement accounts, investments, CDs

• Employment verification:
  Lenders often contact your employer

• Credit report authorization

• Signed purchase agreement (when you make an offer)

If you’re self-employed, expect additional paperwork.

8. Special Factors That May Help or Hurt Your Approval

Beyond the basics, lenders consider several additional factors.

Strengthening Factors (“Compensating Factors”)

• High credit score

• Large down payment

• Significant savings

• Long employment history

• Low DTI

• Strong residual income (especially for VA loans)

Risk Factors

• High DTI

• Limited or unstable employment history

• Recent bankruptcies or foreclosures

• Insufficient savings

• Low credit score

• Frequent credit inquiries or new accounts

Even with risk factors, many loan programs offer flexible options—especially for first-time buyers or those with modest incomes.

9. Pre-Approval vs. Pre-Qualification

Pre-Qualification

• Quick estimate of what you might afford

• Usually doesn’t require verifying documentation

• Useful early in the home-shopping process

Pre-Approval

• Requires full financial review and verification

• Provides a specific loan amount you’re likely to receive

• Strengthens your offer when making bids on a home

Most real estate agents recommend getting pre-approved before home shopping.

10. Steps to Improve Your Mortgage Approval Chances

If your finances aren’t where they need to be—or you simply want the best possible loan terms—consider these strategies:

1. Improve your credit score by paying down balances and avoiding new debt.

2. Lower your DTI by reducing existing debt or increasing income.

3. Save for a larger down payment to reduce borrowing risk.

4. Maintain stable employment and avoid job changes close to applying.

5. Organize your financial documents ahead of time.

6. Avoid large, unexplained deposits before applying.

7. Shop around with multiple lenders to compare rates and requirements.

Conclusion

Qualifying for a mortgage involves meeting a combination of requirements—credit score, income, employment history, DTI ratio, and documentation—but none of these factors alone determines approval. Lenders look at the full picture of your financial health.

Understanding these criteria helps you prepare effectively, identify areas to strengthen, and approach the mortgage process with confidence. Whether you're a first-time buyer or planning an upgrade, meeting these standards puts you on the path to securing a loan that fits your budget and long-term goals.
