California loan guide

Self-Employed Mortgages in California

Self-employed borrowers can use the same agency loans as anyone else: Fannie Mae counts you as self-employed at 25% or more business ownership, generally reads two years of tax returns, and averages the income they show after a cash-flow analysis. When returns understate your income, bank statement and profit-and-loss programs price that flexibility as non-QM loans.

Who it fits, and who should look elsewhere

Fits the agency path: two years of returns showing stable or rising income, or one year of returns on a five-year-old business you have owned at least a quarter of for five years. Fits the non-QM path: strong deposits or a clean profit-and-loss statement, with returns that write your income down to a fraction of the deposits.

Look elsewhere, for now: your income fell sharply last year and the trend is still falling — an agency underwriter reads the trend, not just the average, and a declining file can be declined at any average. You started the business a few months ago with no prior work in the field: neither path has a history to read.

Requirements

Program rules (Fannie Mae)

Before approving the loan, the lender must weigh five factors: the stability of your income; the location and nature of the business; the demand for what it sells; the financial strength of the business; and its ability to keep generating and distributing enough income for you to make the payments.
Income is documented with signed personal federal returns for two years, plus business returns in most cases, or with IRS transcripts covering the same period.
Business returns can be waived when two years of personal returns are provided, you are paying the down payment, closing costs and reserves from personal funds, the business is at least five years old, and your personal returns show rising self-employment income.
The lender completes a written cash-flow analysis (Form 1084 or an equivalent tool) and keeps it in the file. Income reported by a partnership or S corporation is not assumed to be cash in your pocket: the analysis tests what the business can actually distribute while staying viable.
If you use business assets for the down payment, closing costs or reserves, the lender must run a business cash-flow analysis showing the withdrawal will not damage the business.
A co-borrower's self-employment income that is not used to qualify does not have to be documented — but any business debt you are personally obligated on still counts in your debt-to-income ratio.

Lender overlays and non-QM alternatives

Bank statement programs: 12 or 24 months of deposits instead of returns, with an expense factor on business accounts. Every figure is the lender's own.
Profit-and-loss programs: a CPA or licensed preparer prepares a P&L and the lender qualifies from it, sometimes with a few months of statements in support. Useful when deposits are a poor proxy for income.
Individual agency lenders may add their own floors for credit, reserves or time in business on top of the rules above.

Real costs

The agency path costs the least when it works: standard pricing, standard fees, and the full range of down payment options for the loan type.
The non-QM premium is the price of documenting income differently, paid monthly for as long as the loan lasts or again in closing costs when you refinance out of it.
Professional fees: a CPA letter or a preparer-built P&L costs money before the loan does; on a bank statement file, the letter that supports a lower expense factor is often the highest-value document in the package.
Time: two years of personal and business returns, transcripts and a cash-flow analysis take longer to underwrite than a pay stub. Start the document pull before the home search, not after an offer is accepted.

California specifics

California changes the size of the problem, not the rules. At California prices, a modest gap between deposited income and taxable income becomes a six-figure gap in buying power, and many files land above the conforming limit, where lenders read documentation more strictly, not less. Run your own income both ways — returns first, deposits second — at the price you actually intend to pay, before choosing a program.

Worked example: a California contractor, three ways

A general contractor files as a sole proprietor. Schedule C net profit: $84,000 two years ago, $96,000 last year.

Agency path, returns as filed: two-year average = ($84,000 + $96,000) ÷ 2 = $90,000 a year = $7,500 a month. The trend is rising, which supports using the average.
Agency path with Form 1084 add-backs: the returns as filed are not the final number. On Fannie Mae's Cash Flow Analysis (Form 1084), the lender starts from Schedule C net profit and adds back the non-cash deductions — depreciation (Schedule C, line 13), depletion (line 12) and amortization/casualty loss (Schedule C, Part V) — because they reduced taxable profit without reducing cash. A nonrecurring other loss is likewise excluded from the analysis: the lender adjusts cash flow by that amount rather than letting a one-time event cut a forward-looking income figure. Suppose this contractor claimed depreciation of $12,000 two years ago and $14,500 last year, plus amortization of $1,200 in each year, and no depletion (a contractor normally has none to claim — the depletion line applies where the business actually claims it). Two years ago: $84,000 + $12,000 + $1,200 = $97,200. Last year: $96,000 + $14,500 + $1,200 = $111,700. Adjusted two-year average = ($97,200 + $111,700) ÷ 2 = $104,450 a year = $8,704 a month — $1,204 a month more than the $7,500 the unadjusted returns show. Not everything moves in the borrower's favor: Form 1084 subtracts the nondeductible portion of travel and meals expenses, so run the worksheet in both directions before assuming add-backs only help.
Bank statement path: business deposits of $240,000 over 12 months at the common 50% default expense factor give $240,000 × 50% = $120,000 a year = $10,000 a month — $2,500 a month more than the returns show.
Bank statement path with a documented expense ratio: at a 20% factor, $240,000 × 80% = $192,000 a year = $16,000 a month.

The decision rule is arithmetic, not preference: if $7,500 a month of qualifying income as filed — or $8,704 a month after the Form 1084 add-backs above — carries the home you want, take the agency loan and its lower cost. If it does not, the non-QM premium is buying the difference between that agency figure and $10,000–$16,000 a month of counted income.

Which returns the lender reads, by entity

Self-employment income is documented with signed personal federal returns, plus business returns in most cases (Fannie Mae Selling Guide B3-3.5-01). Which business return — and which schedule carries your share of the income into the Form 1084 analysis — depends on how the business is organized:

Entity	Returns and schedules the lender reads
Sole proprietor	Personal Form 1040 with Schedule C (Profit or Loss from Business). There is no separate business return; Form 1084 analyzes Schedule C directly, including its depreciation, depletion and amortization add-backs.
S corporation	Personal Form 1040, plus the business Form 1120S and your Schedule K-1 (Form 1120S), which states your share of the corporation's income; any W-2 wages the corporation pays you also appear on the personal return. Form 1084 has a dedicated 1120S section.
Partnership	Personal Form 1040, plus the business Form 1065 and your Schedule K-1 (Form 1065), which states your share of partnership income and any guaranteed payments. Form 1084 has a dedicated 1065 section.
C corporation	Personal Form 1040 (which shows any W-2 wages and dividends the corporation pays you), plus the business Form 1120. Form 1084 counts corporate earnings only when the borrower owns 100% of the corporation.

For a partnership or S corporation, the K-1 share is not assumed to be cash in your pocket: the lender tests whether the income was actually distributed, or whether the business has the liquidity to distribute it while staying viable.

How the process runs

Income review before house hunting. The lender runs the cash-flow analysis on your returns and, if needed, the deposit math on your statements, so you shop with a number that survives underwriting.
Application and disclosures. On a home you will live in, you receive a Loan Estimate after applying and a Closing Disclosure at least three business days before signing. A refinance of your main home carries a three-business-day right to cancel after signing; a purchase does not.
Verification. Expect IRS transcripts, proof the business is operating, and questions on any year that fell.
Closing and funding follow the disclosure and rescission timelines for the loan type.

Mistakes and downsides, with numbers

Writing off everything in the year before you buy. On a two-year average, $12,000 of extra deductions taken in one year alone costs $500 a month of qualifying income ($12,000 ÷ 2 years = $6,000 a year = $500 a month); $12,000 deducted in both years costs $1,000 a month. Either way, plan the timing with your tax preparer a year or two ahead, not at filing time.
Averaging away a decline. Returns of $120,000 then $70,000 average $95,000, but the underwriter reads a business losing altitude; the file can fail on stability even though the average looks adequate.
Pulling the down payment out of the business without a paper trail. Business assets used for the purchase trigger a second cash-flow test on whether the business survives the withdrawal.
Skipping the agency test. Borrowers who assume their returns fail, and never run the Form 1084 analysis, pay non-QM prices for years on a loan they could have had at agency pricing.

Questions people ask

Am I self-employed if I only own part of a business?

At 25% or more ownership, yes, under Fannie Mae's definition — whatever your job title says. Below that line, your income from the business is treated under other income rules.

How many years of tax returns do I need?

Generally two years of personal returns, plus business returns unless the waiver conditions are met. One year can be enough when the business has existed five years and you have held 25% or more of it for five consecutive years.

Can I qualify with less than two years of self-employment?

Sometimes. Your signed returns must show a full 12 months of income from the current business, and you must document prior income at the same or greater level in a field providing the same products or services, or in a role with similar responsibilities.

What if my income went down last year?

Expect hard questions, and possibly a decline, on the agency path: stability and trend are formal underwriting factors. A bank statement program reading recent deposits may see a different picture if the business has recovered.

Do I need business tax returns as well as personal ones?

Usually, yes. They can be waived when you have two years of personal returns, pay all transaction funds personally, have been in the same business at least five years, and your personal returns show rising income.

What down payment and credit score do I need if I am self-employed?

Self-employment changes how your income is documented, not the program's down-payment or credit framework. On the agency (conventional) path for a home you will live in, the framework is the standard one: as little as 3% down on an eligible one-unit principal-residence purchase — the 97% loan-to-value options, including first-time buyer paths — and a 620 credit score as the program floor to plan around (the lowest score shown in the Fannie Mae Eligibility Matrix). Desktop Underwriter weighs the whole file rather than the score alone, and individual lenders may add overlays above the floor. Non-QM bank statement and profit-and-loss programs set their own down-payment and credit figures as lender overlays.

Can I use money in the business for my down payment?

Yes, if the lender's cash-flow analysis shows the business can spare it. Expect to provide recent business statements or a balance sheet to support that judgment.
