How Much House Can I Afford in San Jose? A Complete 2025 Guide

Buying a home in San Jose comes with a unique challenge:
prices vary widely by neighborhood, school district, and home condition — and traditional affordability calculators rarely tell the full story.

If you want to understand what you can actually afford in today’s market, you need a clear picture of:

• your income and debt

• how lenders calculate approval

• how interest rates affect payments

• real home prices in San Jose neighborhoods

• what monthly payment you’re comfortable with

• your long-term goals

This guide combines lender rules with real San Jose examples so you can get a precise and realistic sense of your purchasing power.

Step 1: Understand How Lenders Calculate Affordability

Lenders typically use a formula based on:

✔ Debt-to-Income Ratio (DTI)

Most buyers qualify at 43% DTI, but strong borrowers — especially in tech — often get approved at lower DTIs.

✔ Income Type

San Jose buyers often have a mix of:

• Base salary

• RSUs

• Annual bonuses

• Self-employed income

Each is treated differently.

✔ Down Payment

Common down payment tiers:

• 5%

• 10%

• 20%

• 25%+ (common with move-up tech buyers)

✔ Credit Score

Higher scores mean better pricing and lower monthly payments.

If you're unsure where to start, here’s the complete guide to the home buying process.

Step 2: Translate the Math Into Real San Jose Home Prices

Below are realistic examples based on current market trends.

Step 3: What Monthly Payment Should You Aim For?

Lender approval = what you can buy
Payment comfort = what you should buy

This is where most people need guidance.

General rule of thumb:

Your monthly housing payment should be:

👉 No more than 25–30% of your gross monthly income
OR
👉 No more than 35–40% of your take-home income (in higher-cost markets like San Jose)

Your comfort is more important than lender limits.

Step 4: How Interest Rates Affect What You Can Afford

A 1% rate change may adjust your affordability by $120K–$180K in San Jose.

Lower rates = higher competition
Higher rates = lower competition
