How to Get Pre-Approved for a Mortgage in California

Pre-approval is the first real step in buying a home. Without it, you're just browsing — and in a market like Southern California, browsing doesn't get you anywhere. Sellers won't look at your offer. Your agent can't negotiate for you with any credibility. And you don't actually know what you can afford until a lender has looked at your whole financial picture and put it in writing.

Getting pre-approved doesn't have to be stressful. It's a straightforward process when you know what to expect and what to prepare. Here's exactly what you need to know.

What Lenders Look At

A lender is trying to answer one question: can this person reliably make their mortgage payment? To figure that out, they look at four main things.

Credit score. This affects whether you qualify at all and what interest rate you get. FHA loans accept scores as low as 580. Conventional loans typically require 620 or higher. But the difference between a 680 and a 740 can mean a meaningfully lower rate — which translates to hundreds of dollars a month over the life of the loan. If your score has room to improve, it may be worth taking a few months to work on it before applying.

Income and employment history. Lenders want to see two years of stable employment in the same field. That doesn't mean you have to be at the same company for two years — job changes within the same industry are usually fine. What they're looking for is consistency. Self-employed? You'll need two years of tax returns showing your net income, and lenders will use an average of those two years, not your current earnings.

Debt-to-income ratio (DTI). This is your total monthly debt payments divided by your gross monthly income. Lenders generally want to see a DTI at or below 43–50% depending on the loan type. Car payment, student loans, credit cards, minimum payments — all of it counts. Paying down high balances before you apply can significantly improve what you qualify for.

Assets and savings. Lenders want to verify you have the funds for your down payment and closing costs — and that the money has been sitting in your account, not just arrived. Large cash deposits without a paper trail can cause issues. If family is gifting you money for a down payment, there are specific gift letter requirements your lender will walk you through.

Documents You'll Need to Gather

Getting these together before you sit down with a lender will speed up the process significantly. Most lenders can work digitally, so scanned or PDF versions are fine.

• Last two years of W-2s (or federal tax returns if self-employed)
• Most recent 30 days of pay stubs
• Last two months of bank statements — all accounts, all pages
• Government-issued photo ID (driver's license or passport)
• Social Security number (for the credit pull)
• Any additional income documentation — rental income, alimony, Social Security, pension
• If you own other properties, mortgage statements and tax returns showing rental income

Pre-Qualified vs. Pre-Approved — Know the Difference

Pre-qualification is a quick estimate based on what you tell the lender verbally or through a short form. No documents verified. No credit pull. It takes five minutes and means almost nothing when you're competing for a home.

Pre-approval is the real thing. The lender reviews your actual documents, pulls your credit, and issues a letter stating they're committed to lending you a specific amount, subject to final underwriting and the property qualifying. Sellers and their agents know the difference — and they'll ask to see it before considering your offer seriously.

How Long It Takes and How Long It Lasts

With a responsive lender and all your documents ready, pre-approval typically takes one to three business days. Some lenders can turn it around in 24 hours. The process moves at the speed of how quickly you submit your documents.

A pre-approval letter is typically valid for 90 days. After that, the lender will need to re-pull your credit and verify your income again. If your home search takes longer than three months — which is common — expect to renew it. It's not a big deal, just something to plan for.

What About the Credit Pull?

Pre-approval requires a hard credit inquiry, which temporarily drops your score by a few points. This is normal and expected. Here's the good news: if you're comparing lenders and get your credit pulled multiple times within a 14–30 day window, the credit bureaus typically count all those pulls as a single inquiry. So you can shop a couple of lenders without wrecking your score — just do it within a concentrated window of time.

Choosing the Right Lender

You have options: local mortgage brokers, community banks, credit unions, or big national banks. There's no universally right answer, but for buyers in Southern California — especially those using FHA or VA financing — working with a local lender who knows this market is usually an advantage.

A local lender picks up the phone. They know the escrow companies, the timelines, and the quirks of SoCal real estate. In a competitive offer situation, a seller's agent who recognizes and trusts the lender on your pre-approval letter can actually make a difference in whether your offer gets accepted.
