California loan guide

Bank Statement Loans in California

A bank statement loan qualifies a self-employed borrower on 12 or 24 months of bank deposits instead of tax returns: the lender averages the deposits that count, reduces them by an expense factor for business accounts, and treats the result as monthly income. It is a non-QM loan — each lender writes its own guidelines, and the lender must still judge that you can repay.

Who it fits, and who should look elsewhere

Fits: your business deposits are strong and steady, but legal write-offs leave your tax returns showing a fraction of what you take in; you have at least a year, and usually two years, of self-employment; and you can document where the deposits come from.

Look elsewhere: your tax returns already support the loan — a conventional loan following Fannie Mae's self-employment rules costs less, and a bank statement loan's pricing premium buys you nothing. Your deposits are shrinking, full of transfers between your own accounts, or padded with loan proceeds and one-off windfalls: those deposits are stripped out, and the income left may be lower than your return shows. You have been self-employed for only a few months: most programs want a year or more of history behind the statements.

Requirements

The one federal rule that applies

Bank statement loans sit outside the Qualified Mortgage definition, so no agency guideline governs them. Federal law still requires the lender to make a reasonable, good-faith determination that you can repay, using income and debts it has checked. "No tax returns" never means "no income check" — the statements are the income check.

Typical lender overlays

Statements: 12 or 24 consecutive months, every page, from personal accounts, business accounts, or both. Gaps and missing pages stop the file.
Deposit screening: transfers between your own accounts, loan proceeds, gift money and other non-income deposits are excluded. Large or unusual deposits need a documented source. Cash deposits draw the hardest questions.
Expense factor: business deposits are reduced by an expense factor because the money still has to run the business. The default is commonly 50%. A letter from a CPA, tax preparer or, at some lenders, the borrower, documenting a lower actual expense ratio can move the factor — and the income — substantially.
Ownership: if you own part of the business, your qualifying share is typically scaled to your ownership percentage.
Reserves: commonly three to six months of payments after closing, rising with loan size.
Account health: a pattern of overdrafts or returned items reads as a struggling business, whatever the deposit total says.

Real costs

Pricing premium: non-QM pricing sits above agency pricing for the same borrower profile. The premium is the product; compare it against waiting until your returns support an agency loan.
Manual underwriting time: a human rebuilds your income from hundreds of deposits. Files move slower than a W-2 file, and conditions multiply when deposits need explaining.
Larger down payments at weaker credit: in current programs the step from stronger to weaker credit commonly moves the requirement from 10% down to 20% — on an $850,000 purchase, that is the difference between $85,000 and $170,000.
The exit cost: many borrowers treat the loan as a bridge and refinance into an agency loan once two years of returns support it, paying a second set of closing costs to escape the premium.

California specifics

California's prices push bank statement files into jumbo territory, where documentation gets heavier, not lighter. The deposit math that qualifies a borrower in the Central Valley at a $500,000 price must produce roughly double the income for a $1,000,000 coastal purchase, at the same expense factor. Run the arithmetic at the price you actually intend to pay, in the county you intend to pay it, before falling for a program's maximum loan amount.

Worked example: one borrower, four income answers

A consultant's business account shows $240,000 of qualifying deposits over 12 months, after transfers and a loan deposit are stripped out.

12-month business statements, 50% factor: $240,000 × 50% = $120,000 a year = $10,000 a month of qualifying income.
Same deposits, CPA letter supports a 20% factor: $240,000 × 80% = $192,000 a year = $16,000 a month. One letter, $6,000 a month more income — $72,000 a year.
24-month program: the prior year deposited $192,000, so the two-year total is $432,000. At 50%: $432,000 × 50% ÷ 24 = $9,000 a month. The longer window costs this growing business $1,000 a month against the 12-month figure.
Tax return: after write-offs, the return shows $78,000 — $6,500 a month. That is the number an agency lender starts from, before any add-backs.

Same business, same money: $6,500, $9,000, $10,000 or $16,000 a month depending on the path. At a lender's debt-to-income limit, that spread decides the price of home you can buy — which is why the expense factor, not the deposit total, is the number to negotiate over.

How the process runs

Statements review first. A competent lender runs the deposit math — screening, averaging, expense factor — before an application is taken, so the qualifying income is known early.
Application and disclosures. On a home you will live in, this is a consumer mortgage: you receive a Loan Estimate after applying and a Closing Disclosure at least three business days before signing, and a refinance of your main home carries a three-business-day right to cancel after signing.
Underwriting. Expect conditions on large deposits, business licensing or registration where it applies, and proof the business is still operating.
Closing. Funds move after any rescission period on a refinance; a purchase closes on the contract timeline.

Mistakes and downsides, with numbers

Applying before cleaning up the accounts. Every transfer between your own accounts must be paper-trailed. A $30,000 transfer counted as a deposit inflates the average by $2,500 a month — and collapses the file when underwriting removes it.
Accepting the default expense factor. At $240,000 of deposits, the difference between a 50% factor and a documented 20% factor is $72,000 a year of qualifying income.
Picking 12 months because it is faster. For a seasonal business, the window decides the answer: a strong 12 months can beat 24, and a weak recent year can sink a file that 24 months would have carried.
Paying non-QM prices when your returns already work. If the tax-return path qualifies you, the bank statement premium — paid every month for years, or again at a refinance — buys nothing.

Questions people ask

Do I need to show tax returns at all?

On a bank statement program, no — the statements replace the returns as the income record. The lender will still check the business exists and is operating, and may ask for a business license or a preparer's letter.

How is my income calculated?

Qualifying deposits are totaled, divided by the number of months, and reduced by the expense factor on business accounts. Personal accounts carry little or no factor at some lenders.

What is an expense factor?

The share of deposits the lender assumes went to running the business. It is commonly 50% by default on business accounts and can be lower when a letter documents your actual expense ratio.

Can I combine personal and business statements?

Many programs allow it, provided transfers between the accounts are counted once, not twice. Each account's role must be clear.

How much down payment will I need?

Commonly 10% with stronger credit and 20% with weaker credit in current programs, with larger loans and lower scores pushing the requirement up.

Is a bank statement loan a QM loan?

No. It is a non-QM loan, which means no agency guideline governs it and the lender sets its own terms — but federal law still requires a reasonable, good-faith judgment that you can repay.
