Does Your Car Payment Hurt Your Mortgage Approval?

Your monthly car payment could be quietly reducing how much home you can afford. Here's how auto debt impacts your mortgage borrowing power in California.

You might be surprised to learn that your car payment is one of the biggest factors quietly working against your mortgage approval. This is something I see come up regularly with first-time buyers, and it's worth understanding before you start house hunting.

Lenders look at your debt-to-income ratio (DTI) — essentially, how much of your monthly income is already committed to existing debt payments. Your car loan counts toward that number. In high-cost California markets, even a modest car payment of $400–$600 per month can reduce your home buying power by tens of thousands of dollars.

For example, if your lender caps your total monthly debt at 43% of your gross income, every dollar going toward your car is a dollar that can't go toward a mortgage payment. That translates directly into a lower maximum loan amount.

So what can you do? If you're planning to buy in the next 6–12 months, consider paying down or paying off your auto loan first. Even reducing the balance can help. Also, avoid taking on any new debt — no new car loans, no new credit cards — while you're in the mortgage process.
