Buying a home in California is expensive. Really expensive.
But that doesn't mean you can't afford one. You just need to know the math that lenders use — and the real numbers you'll actually qualify for.
I'm Bill McCoy, a California mortgage broker with 15 years of experience (CA DRE #01212512). I've helped hundreds of buyers figure out exactly what they can afford, and I'll show you the same process we use.
The Quick Formula: 3x to 4x Your Income
The simplest rule of thumb? You can typically afford a home that costs 3 to 4 times your gross annual income.
If you make $100,000/year, you're likely looking at homes in the $300,000 to $400,000 range. In California, that might get you a condo in some markets, or a starter home in the Central Valley.
But this is just a starting point. The real calculation is more nuanced.
What Lenders Actually Look At: DTI Ratio
Lenders don't care what you think you can afford. They care about your debt-to-income ratio (DTI).
DTI = (Total Monthly Debt Payments) ÷ (Gross Monthly Income)
Most conforming loans max out at a 43% DTI, though some programs allow up to 50% with strong credit and reserves.
Here's what counts as "debt":
- Your future mortgage payment (principal, interest, taxes, insurance, HOA)
- Car payments
- Student loans
- Credit card minimum payments
- Personal loans
What doesn't count:
- Utilities
- Groceries
- Insurance (except homeowners, which is included in your mortgage payment)
Broker's Tip: If your DTI is above 43%, pay down debt before you shop for a mortgage. Even $200/month in student loan payments can cost you $40,000+ in buying power.

Example 1: $100,000 Income, No Debt
- Gross monthly income: $8,333
- Max DTI (43%): $3,583/month
- Estimated property tax + insurance + HOA: ~$800/month
- Available for P&I payment: $2,783/month
- Home price you qualify for: ~$450,000
Example 2: $150,000 Income, $600/Month Debt
- Gross monthly income: $12,500
- Max DTI (43%): $5,375/month
- Existing debt: $600/month
- Remaining for housing: $4,775/month
- Estimated property tax + insurance + HOA: ~$1,200/month
- Available for P&I: $3,575/month
- Home price you qualify for: ~$575,000
Example 3: $200,000 Income, Clean Credit
- Gross monthly income: $16,667
- Max DTI (43%): $7,167/month
- Estimated property tax + insurance + HOA: ~$1,600/month
- Available for P&I: $5,567/month
- Home price you qualify for: ~$900,000
Notice the pattern? Your existing debt matters a lot.
Down Payment Requirements
You also need cash. Here's what different loan types require:
| Loan Type | Minimum Down Payment | Example on $500K Home |
|---|---|---|
| Conventional | 3% (first-time buyers) | $15,000 |
| FHA | 3.5% | $17,500 |
| VA | 0% | $0 |
| Jumbo | 10-20% | $50,000-$100,000 |
But don't forget closing costs (2-5% of the purchase price). On a $500,000 home, that's another $10,000-$25,000.

California-Specific Challenges
California is one of the most expensive housing markets in the country. Here's what that means for you:
Property Taxes: California caps property tax increases at 2% per year (Prop 13), but your initial tax is based on purchase price. Expect ~1.25% of the home's value annually.
High Home Prices: The median home price in California is over $800,000 in many coastal markets. Even with a six-figure income, you'll need help.
Down Payment Assistance: Programs like CalHFA MyHome and Dream For All can provide 3.5% to 20% assistance. See all California down payment programs

How to Increase Your Buying Power
If the numbers aren't where you want them, here's how to improve:
1. Pay Down High-Interest Debt
Every $100/month in debt you eliminate adds ~$20,000 to your buying power.
2. Increase Your Credit Score
A 680 score might get you 6.75%, while a 760 gets you 6.25%. That 0.5% difference saves you $150/month on a $500,000 loan — or lets you afford $25,000 more house.
See how to improve your credit score before applying
3. Consider a Co-Borrower
A spouse, partner, or family member with income can double (or more) your buying power.
4. Look at Different Loan Types
FHA loans allow higher DTI ratios. VA loans require zero down. Explore your options.
5. Explore Down Payment Assistance
California has multiple programs that provide grants or low-interest loans for your down payment. You don't have to save $100,000 to buy a home.
Broker's Tip: Don't assume you can't afford a home in California. I've helped buyers making $75,000/year purchase $450,000+ homes using CalHFA assistance programs. The math works if you know the programs.
What About Jumbo Loans?
In most California counties, anything above $832,750 is a jumbo loan. High-cost counties (LA, Orange, San Diego, Bay Area) have limits up to $1,249,125.

Jumbo loans typically require:
- 10-20% down payment
- 700+ credit score
- Lower DTI (usually max 43%, sometimes 38%)
- 6-12 months of reserves (cash in the bank)
The Income You Actually Need
Here's a reverse calculation — what income do you need for popular California price points?
For a $500,000 home (10% down):

- Add taxes, insurance, HOA: ~$800
- Total housing payment: ~$3,550/month
- Income needed (at 43% DTI, no other debt): $99,000/year

Don't Guess — Get Pre-Approved
Online calculators are helpful, but they don't know your full financial picture.
A pre-approval tells you exactly what you qualify for because a lender reviews:
- Your credit report
- Your income documentation (W-2s, paystubs, tax returns)
- Your assets (bank statements)
- Your debt obligations
Learn the difference between pre-qualification and pre-approval
Self-Employed? Different Rules Apply
If you're self-employed, lenders typically average your last 2 years of income. If your business had a bad year in 2024, that drags down your 2026 buying power.

FAQ
Q: Can I afford a $600,000 home making $120,000/year?
A: Probably, if you have minimal debt and at least 10% down. Your DTI would be around 40-42%, which is within limits for most loan programs.
Q: Do lenders count bonuses and commissions?
A: Yes, but they typically average the last 2 years. If you made $100K salary + $20K bonus each year, lenders will count $120K.
Q: What if I'm married but only one person has income?
A: You can qualify on one income. The non-working spouse can still be on the title and loan, they just won't add to the qualifying income.
Q: Does child support or alimony count as income?
A: Yes, if you can document it will continue for at least 3 more years.
Q: Can I use a gift for my down payment?
A: Yes. Most loan programs allow down payment gifts from family members. You'll need a gift letter stating it doesn't need to be repaid.
Q: What if I'm buying with a partner who's not my spouse?
A: You can co-borrow. Both incomes count, and both credit scores are considered (lenders use the lower middle score).
Q: How much house can I afford with a VA loan?
A: VA loans have no set loan limit, but lenders will still check your DTI. With zero down required, your buying power is significantly higher than conventional. See our VA loan guide
