How Much House Can I Afford in the Bay Area? (2026)
Every Bay Area buyer starts in the same place: how much house can I actually afford? Answer it first and everything after it — the saved searches, the open houses, the offers — gets easier. Our free BuyAbility check gives you a working number in minutes, but it helps to understand what goes into it.
The four numbers that decide it
- ·Your gross monthly income, before taxes
- ·Your monthly debts — car payments, student loans, credit cards
- ·Your down payment, and how much cash you keep in reserve
- ·Today's interest rate, which sets how far your monthly payment stretches
The rule lenders actually use
Lenders look at your debt-to-income ratio, or DTI: the share of your gross monthly income that goes to debt, including the new mortgage. Many conventional loans want total DTI somewhere in the 36 to 43 percent range, though it varies by loan type and credit.
Your housing payment is more than principal and interest. It is PITI: principal, interest, property taxes, and insurance, plus any HOA dues. In the Bay Area, taxes and insurance move your real budget meaningfully.
The Bay Area twist
High prices mean small changes in rate or down payment swing your buying power a lot. If you are a move-up buyer, the equity from your current home is usually the biggest lever — and how much of it you keep when you sell matters as much as the sale price.

Frequently asked questions
What credit score do I need to buy a home in California?
There is no single cutoff, but many conventional loans look for a score around 620 or higher, and a stronger score earns a lower rate. FHA loans can allow lower scores. Your lender can tell you exactly where you stand.
How much down payment do I need in the Bay Area?
It varies by loan. Conventional loans can start near 3 to 5 percent down, FHA around 3.5 percent, and 20 percent down avoids private mortgage insurance. Given Bay Area prices, even a small percentage is a large dollar figure, so plan your reserves.
Should I get pre-approved before touring homes?
Yes. A pre-approval tells you your real budget and shows sellers you are serious. In a competitive market, many sellers will not consider an offer without one.
