How Much Home Can I Afford in California?

The most useful number to know before you shop for a home is not the price you wish you could afford, but the price a lender will actually approve and you can comfortably carry. In California, where prices are high, getting that number right matters more than almost anywhere else. It comes down to a few factors you can estimate yourself, and then confirm with a lender through pre-approval.

Debt-to-income is the core

Lenders decide how much you can borrow largely through your debt-to-income ratio, or DTI. This compares your total monthly debt payments, including the new mortgage, to your gross monthly income before taxes. Most programs want your DTI at or below somewhere in the range of 43 to 50 percent, though the exact limit depends on the loan type and your overall profile.

Here is the practical version. Take your gross monthly income and multiply by your target DTI to get the total monthly debt the lender will allow. Subtract your existing monthly debts, like car loans, student loans, and minimum credit card payments. What is left is the budget for your full housing payment.

Your payment is more than principal and interest

That housing payment has to cover more than just the loan. It includes principal and interest, but also property taxes, homeowners insurance, and any HOA dues, often abbreviated together as PITI plus HOA. In California, property taxes run roughly 1.1 to 1.25 percent of the purchase price per year, and insurance varies by area and risk. All of it has to fit inside the budget you calculated from your DTI.

Once you know how much of your monthly budget is available for principal and interest, the interest rate and loan term determine how large a loan that supports. A lower rate, or a larger down payment, increases the price you can reach. Our affordability calculator runs this whole chain when you enter your own income, debts, rate, and down payment, including any assistance.

The down payment lever

Your down payment does two things: it reduces the loan you need, and it can eliminate mortgage insurance once you reach 20 percent on a conventional loan. But you do not need 20 percent to buy. Many California buyers put down 3 to 3.5 percent and use assistance programs to help cover even that. A smaller down payment means a larger loan and a higher payment, so it is a tradeoff, but it is often the difference between buying now and waiting years to save.

If down payment is your obstacle, our guide to down payment assistance shows what help exists. The assistance can raise your effective buying power without raising your monthly payment.

Why pre-approval matters

An affordability estimate tells you roughly where you stand. Pre-approval makes it real. A lender reviews your income, credit, and debts and issues a letter stating what they will actually lend, which sharpens your budget and, just as important, makes your offers credible to sellers. In a competitive market, a seller is far more likely to take an offer backed by a solid pre-approval than one without.
