How Much House Can You Afford in San Diego in 2026? (First-Time Buyer Guide)

Buying a home in San Diego is exciting—but one of the biggest questions buyers have is: how much house can I actually afford?

With high home prices and a competitive market, understanding your budget is crucial before you start house hunting. In this guide, we’ll break down exactly how affordability works, what lenders look at, and how you can confidently determine your price range in 2026.

Most lenders follow guidelines where housing costs stay around 28–30% of income and total debt stays under ~43%.

What Determines How Much House You Can Afford?

1. Your Income

Lenders look at your monthly income to determine how much you can handle in mortgage payments. The higher your stable income, the more you may qualify for.

2. Your Debt-to-Income Ratio (DTI)

This is one of the biggest factors.

Most lenders prefer:

• Under 43% DTI

• Lower = better approval odds

This includes:

• Car payments

• Credit cards

• Student loans

3. Your Credit Score

Your credit score impacts:

• Loan approval

• Interest rate

Typical minimums:

• ~620 for conventional loans

• ~580 for FHA loans

Higher score = lower monthly payment

4. Your Down Payment

Your down payment directly affects:

• Monthly payment

• Loan approval

• Interest rate

Examples:

• 3–5% → low entry but higher monthly

• 10–20% → stronger offer + lower payment
