Quick Answer: In San Diego in 2025, most buyers can afford a home priced at roughly 3–5x their gross annual income when using conventional financing with a standard down payment. On a $100,000 household income, that’s a purchase price in the $300,000–$500,000 range though programs like VA loans, FHA, and down payment assistance can stretch that further. The best way to know your exact number is a free pre-approval with a local lender.
San Diego is one of the most desirable places to live in the United States and one of the most expensive. With median home prices well above $800,000 in many neighborhoods, figuring out what you can actually afford is the first and most important step in the homebuying process.
The good news: affording a home in San Diego is more achievable than the headlines suggest. Here’s how to think through the numbers.
The Basic Formula: What Lenders Look At
Mortgage lenders use a metric called the debt-to-income ratio (DTI) to determine how much you can borrow your monthly debt obligations as a percentage of your gross monthly income.
As a general guideline:
- Front-end DTI (housing costs only): should be 28% or less of gross monthly income
- Back-end DTI (all debts including housing): should be 43% or less, though many programs allow up to 50%
Example: If your household earns $10,000/month gross, a lender typically wants your mortgage payment (including taxes and insurance) to be no more than $2,800/month and your total monthly debts including the mortgage to stay under $4,300–$5,000.
What Does That Buy You in San Diego in 2025?
Using current average interest rates and typical property tax rates for San Diego County, here’s a rough guide to purchase price by income:
Household Income | Max Monthly Payment* | Estimated Purchase Price | Down Payment Needed |
$80,000/yr | ~$1,870/mo | ~$320,000 | ~$16,000 (5%) |
$120,000/yr | ~$2,800/mo | ~$480,000 | ~$24,000 (5%) |
$160,000/yr | ~$3,730/mo | ~$640,000 | ~$32,000 (5%) |
$200,000/yr | ~$4,670/mo | ~$800,000 | ~$40,000 (5%) |
$250,000/yr | ~$5,830/mo | ~$1,000,000+ | ~$50,000+ (5%) |

Factors That Affect How Much You Qualify For
Credit Score
Your credit score directly impacts the interest rate you receive. A difference of even 50 points can change your rate by 0.25–0.75%, which meaningfully affects your monthly payment and maximum purchase price.
Down Payment
A larger down payment reduces your loan amount, lowers your monthly payment, and may eliminate PMI on conventional loans. But it doesn’t have to be 20% many loan programs accept 3–5% down, and VA loans require zero.
Existing Debt
Student loans, car payments, and credit card minimums all count against your DTI. Paying down debt before applying can meaningfully increase your buying power.
Loan Program
Different loan programs have different rules. VA loans (for eligible military) and FHA loans often allow higher DTIs and lower down payments than conventional loans, stretching your purchasing power further.
San Diego Down Payment Assistance Programs
Many buyers don’t realize how many down payment assistance programs are available in San Diego County. These include:
- CalHFA MyHome Assistance Program deferred-payment junior loan for down payment and closing costs
- San Diego Housing Commission (SDHC) programs for income-qualified buyers in the City of San Diego
- CalHFA Dream For All — shared appreciation loan for first-time buyers
- National Homebuyers Fund (NHF) — grants up to 5% of the loan amount
