Use the 28/36 rule, understand lender math, and see real affordability estimates by income level — so you can shop with confidence.
Key Takeaway
In California, you can typically afford a home priced at 3–5× your annual income. A household earning $100,000/year can afford approximately $400,000–$500,000 using the 28/36 DTI rule at current rates. Your actual budget depends on your down payment, credit score, existing debts, and the loan program you choose.
Most lenders use the 28/36 rule as a starting point to determine how much you can borrow.
Your total monthly housing costs should not exceed 28% of your gross monthly income. Housing costs include:
Example:If your gross monthly income is $8,333 ($100K/year), your max housing payment is $8,333 × 0.28 = $2,333/month.
Your total monthly debt payments — housing plus all other debts — should not exceed 36% of your gross monthly income. Other debts include:
Example:At $100K/year, your max total debt payments are $8,333 × 0.36 = $3,000/month. If you have $500/month in car and student loans, your max housing payment drops to $2,500.

Lenders look beyond your income. Here are the key factors that determine your borrowing power.
Your credit score directly affects your interest rate and loan eligibility. A score of 740+ typically qualifies you for the best conventional rates. Scores between 620–739 still qualify but at higher rates. FHA loans accept scores as low as 580 (or 500 with 10% down). A higher score means a lower rate, which means you can afford more home for the same monthly payment.
DTI is the percentage of your gross monthly income that goes to debt payments. Conventional loans typically cap total DTI at 43–45%. FHA loans may allow up to 50% with compensating factors. Lower DTI means more room for a mortgage payment and a higher purchase price.
A larger down payment reduces the loan amount you need, lowers your monthly payment, and may eliminate mortgage insurance. Putting 20% down on a conventional loan avoids PMI entirely. With less than 20% down, PMI adds $50–$200+ per month depending on loan size and credit score.
Lenders want to see that you have savings beyond your down payment and closing costs. Typically, 2–6 months of mortgage payments in reserve strengthens your application. For jumbo loans, 6–12 months of reserves may be required. Strong reserves can also be a compensating factor that helps offset a higher DTI ratio.
California has unique costs and regulations that impact how much home you can afford.
Thanks to Proposition 13, California property tax rates are capped at roughly 1% of the assessed value at purchase, plus local bonds and assessments. This typically totals about 1.1% annually. On a $500,000 home, that's approximately $5,500/year or $458/month added to your housing costs.
California homeowners insurance typically costs $1,200 to $2,500 per year, though costs have been rising — especially in wildfire-prone areas where premiums can exceed $5,000. Lenders require insurance as part of your PITI payment, and higher premiums reduce your borrowing power.
Many California condos and planned communities require HOA dues ranging from $200 to $600+ per month. Lenders include HOA fees in your front-end ratio calculation, which directly reduces the mortgage payment you can qualify for. Always factor HOA costs into your budget.
Newer developments in California often have Mello-Roos Community Facilities District taxes to fund local infrastructure. These special assessments can add $2,000 to $8,000+ per year on top of regular property taxes. Mello-Roos is included in your housing cost calculation by lenders.
Practical steps you can take to qualify for a higher purchase price.
Even a 40-point increase can save you 0.25–0.5% on your interest rate. On a $400,000 loan, that's $60–$120 less per month — or $20,000–$40,000 more in buying power. Pay down credit card balances, dispute errors, and avoid opening new accounts before applying.

A larger down payment means a smaller loan, a lower monthly payment, and possibly no PMI. Going from 5% down to 20% down on a $500,000 home reduces your loan from $475,000 to $400,000 — saving roughly $475/month in principal, interest, and mortgage insurance.
California's CalHFA offers several DPA programs that can provide 3–10% of the purchase price toward your down payment and closing costs. The Forgivable Equity Builder Loan, for example, offers up to 10% as a forgivable second mortgage. These programs can dramatically increase what you can afford.
California first-time buyer grants →Adding a spouse, partner, or family member as a co-borrower combines your incomes for qualification purposes. Two incomes of $60,000 each qualify for significantly more than one income of $60,000. The co-borrower's debts are also factored in, so choose a co-borrower with low debt obligations for maximum benefit.
