Mortgage Pre-Approval Checklist for California Buyers

I’m Michael DiVita — DRE #01372066 | NMLS #241655, DiVita Home Finance (DRE #01818285 | NMLS #323700), Tiburon, CA. I’ve been in California mortgage lending since 2000 and founded DiVita Home Finance in 2007. I’m known as a creative mortgage broker: when a bank says no, I find the lender and the loan structure that can say yes. Call (800) 239-1103.

In California, the home search really starts with financing. Sellers expect a pre-approval letter with every offer, and in competitive pockets like Marin, San Francisco, and the Peninsula, the strength of that letter can decide which offer wins. This guide covers the difference between pre-qualification, pre-approval, and a fully underwritten approval; the complete document checklist for W-2 and self-employed buyers; how credit checks work; and what to avoid once you’re approved.

Pre-Qualification vs. Pre-Approval vs. Fully Underwritten Approval

A fully underwritten approval (also called a TBD or credit approval) means an underwriter has already reviewed your income, assets, and credit before you’ve picked a property. What’s left is property-specific: appraisal, title, insurance, and the purchase contract. It can let you write shorter contingency periods with more confidence and helps the listing agent trust your financing. It isn’t a guarantee — your finances still have to stay the same through closing.

Step by Step: How to Get Pre-Approved

1. Check your credit. Know your scores and fix report errors before you apply.
2. Gather your documents (checklist below). A complete package is the biggest factor in speed.
3. Choose your lender or broker. A bank offers its own programs; a broker compares programs and pricing across many wholesale lenders.
4. Apply. The lender pulls credit, reviews documents, and runs your file through automated underwriting.
5. Get your letter — and, for competitive situations, ask about a fully underwritten approval.
6. Keep it current. Credit reports and income and asset documents age out; most lenders need updates after a few months (conventional loans generally require documents no more than about four months old at closing).

Document Checklist: W-2 Employees

Income

• Most recent pay stubs covering about 30 days, from all employers
• W-2s for the last two years
• Federal tax returns for the last two years if you have bonus, commission, rental, self-employment, or other non-wage income (lenders may ask for them regardless)
• Bonus, overtime, or commission income: documentation of history — usually two years, sometimes less with a strong trend
• Social Security, pension, or disability income: award letters and proof of receipt
• Recent job change: offer letter and first pay stub

Assets

• Bank statements for the most recent two months — all pages, all accounts
• Most recent investment and retirement statements
• Gift funds: signed gift letter and proof of the transfer
• Selling your current home: listing agreement, then the signed purchase contract and settlement statement

Identity and other items

• Government-issued photo ID and your Social Security number (or ITIN for ITIN programs)
• Divorce decree and settlement agreement; child support or alimony orders
• Bankruptcy discharge papers, if applicable
• Non-U.S. citizens: green card or visa and work authorization, as applicable
• VA borrowers: Certificate of Eligibility (the lender can often pull it) and DD-214 if needed

Document Checklist: Self-Employed Borrowers

Self-employed files take more paperwork because the lender has to calculate income from your returns. For conventional loans, lenders generally want two years of self-employment history; Fannie Mae can accept a shorter history of at least 12 months when you worked in the same line of work before, and some files qualify with one year of returns. Expect to provide:

• Personal tax returns (Form 1040) for the last two years — all pages and schedules (C, E, F, and K-1s)
• Business returns for the last two years if you own a partnership (1065) or corporation (1120-S or 1120). Sole proprietors report on Schedule C and have no separate business return.
• Year-to-date profit and loss statement, when required — often requested when the application is well into the year
• Business bank statements — two months for most programs; 12–24 months for bank statement loans
• Evidence the business is active, such as a business license or CPA letter

Lenders typically average two years of income and look closely at declines. If your tax returns understate your real cash flow because of legitimate write-offs, bank statement, 1099-only, P&L, or asset-based non-QM programs may qualify you where a bank says no.

Filed an extension?

If your most recent return is on extension and not yet filed, many programs can use your prior two filed years along with a copy of the extension, IRS transcripts, and a year-to-date P&L. Rules vary by program and time of year, and an extension combined with declining income can be a problem, so talk to me before you file or apply.

Large Deposits and “Seasoned” Funds

Underwriters review every bank statement. On a purchase, a single non-payroll deposit greater than half of your monthly qualifying income generally has to be explained and documented. Cash deposits are hard to document and often can’t be used. Avoid moving money between accounts unnecessarily during the process; each transfer can create a paper-trail request. See large bank deposits flagged by a lender.

Does Pre-Approval Hurt Your Credit?

A mortgage credit check is a hard inquiry and may lower scores slightly for a while. Scoring models treat multiple mortgage inquiries within a short shopping window as one inquiry — 45 days in newer FICO versions, but as little as 14 days in older versions that mortgage lenders often use. Do your lender comparison within about two weeks to be safe.

Making Your Offer Stronger Without Overpaying

• Fully underwritten approval so the listing agent can confirm your financing is solid.
• Letter tailored to the offer — the exact price and loan amount, not your maximum.
• Shorter, realistic contingency periods. The standard California Association of REALTORS® purchase agreement sets default contingency periods; with an underwritten file you can often shorten the loan contingency safely. Only waive the appraisal contingency if you can cover a realistic gap in cash.
• Flexible closing date that fits the seller’s plans.
• Escalation clauses can work, but some listing agents prefer clean offers — ask your agent.
• Learn from lost offers. Ask your agent to get feedback from the listing agent: price, financing, terms, or timing.

After You’re Pre-Approved: What Not to Do

• Don’t open new credit, finance a car, or run up card balances.
• Don’t change jobs or pay structure without talking to me first — see changing jobs during the mortgage process.
• Don’t make large undocumented deposits or move down payment funds around.
• Don’t co-sign anyone else’s loan.
• Do respond quickly to requests — once you’re in contract, every day counts. See the California mortgage approval timeline.

Frequently Asked Questions

What’s the difference between pre-qualification and pre-approval?

Pre-qualification is an informal estimate based on what you tell the lender, with no document review and often no credit check. Pre-approval is based on your actual documents and a credit report run through automated underwriting. A fully underwritten approval goes further: an underwriter has conditionally approved your file before you find a home. California sellers expect at least a pre-approval.

How long does pre-approval take?

With a complete document package, a standard pre-approval usually takes about one to three business days. A fully underwritten approval takes longer — often several business days — depending on how complex your income is.

How long is a pre-approval letter good for?

It depends on the lender, but credit reports and income and asset documents age out after a few months. Conventional loans generally require documents no more than about four months old at closing. If your search runs long, your lender will update pay stubs, bank statements, and possibly credit.

Does getting pre-approved hurt my credit?

The credit check is a hard inquiry and can lower scores slightly for a while. Multiple mortgage inquiries within a short window count as one — 45 days in newer FICO versions but as little as 14 days in older versions — so compare lenders within about two weeks.

Can I get pre-approved if I’m self-employed?

Yes. Conventional loans usually use two years of tax returns, though Fannie Mae can accept at least 12 months of self-employment with prior experience in the same field. If your returns understate your income, bank statement and other non-QM programs may qualify you.

What is a fully underwritten (TBD) approval?

It’s a pre-approval in which an underwriter has already reviewed and conditionally approved your income, assets, and credit before you have a property. The remaining conditions are mostly property-related, such as the appraisal, title, and insurance, which makes your offer more credible to sellers.

What if I filed a tax extension?

Many programs can work with your prior two filed years plus the extension, IRS transcripts, and a year-to-date profit and loss statement. Rules differ by program and time of year, so talk to your loan officer before applying.
