How S-Corp and LLC Owners Are Averaged on a Bank Statement Mortgage

The Quick Read: A bank statement mortgage turns a year of business or personal deposits into one monthly income figure. The lender totals the eligible deposits, divides by the months, applies an expense factor on business accounts, and credits you only with your ownership share. Your W-2 salary is not the starting point. The deposits are.

• Deposits drive the number. The lender reads cash flow into your account, not the profit or salary on your tax return.
• Account type changes the math. Business statements get an expense factor. Personal statements usually skip that step.
• Ownership share caps the credit. A 60% owner is credited with 60% of the calculated income, and the lender will want proof of that stake.
• Clean deposits win. Transfers, refunds, and loan proceeds get stripped out before anything is averaged.
• Every program sets its own method. Expense factors, lookback windows, and account rules differ by lender, and every file is underwritten individually.

What “Averaged” Actually Means

Averaging is simple. Your income is rarely the same each month. Some months are big and some are thin. A lender wants one steady number, so it adds up a stretch of eligible deposits and divides by the number of months.

That is why a bank statement mortgage helps owners whose traditional personal-income documentation looks small. Deductions and depreciation shrink taxable income. They don’t shrink the cash that lands in your account. Under this route, the loan is reviewed on documented income under the applicable program, subject to lender guidelines.

These loans are non-QM, meaning non-qualified mortgage. They sit outside the standard box that most conventional loans must fit. Experian’s consumer guide to bank statement loans describes them this way. It also notes that lenders still evaluate whether you can repay. Fewer papers does not mean no scrutiny. Across the select wholesale lenders Lendmire works with, the review of the deposits is often more detailed than a tax-return review.

The Step-by-Step Math

Here is how most programs run the sequence. The details move from lender to lender, but the order is familiar.

1. Choose the account type. Business statements show gross revenue, so an expense factor applies. Personal statements are treated as closer to net income, so the expense step is usually skipped. A lender may still ask for a few months of business statements to see where the personal deposits came from.

2. Pick the lookback. Twelve months is the common window. Some programs allow 24 months, which smooths the average over a longer stretch.

3. Strip out deposits that aren’t revenue. Transfers between your own accounts, refunds, loan proceeds, owner contributions, and one-time asset sales come out first.

4. Total and divide. Add what remains and divide by the number of months. One big month and one weak month blend together.

5. Apply your ownership share. Own 60%? You get credit for 60% of the result.

6. Apply the expense factor. Most programs use a default flat factor on business accounts. Some allow a lower factor when a CPA or licensed tax preparer certifies your actual expenses. Others use a narrative or third-party analysis. Wholesale lenders disagree on the numbers, so treat any factor you read online as one program’s choice, not a rule.

7. The result is monthly qualifying income. It then goes into your debt-to-income ratio, which compares monthly debts to monthly income.

Does the Order Matter?

Not for the final number. Multiplying by the expense factor and by your ownership share gives the same answer in either order. The order matters for the paper trail. The lender needs the deposits cleaned first, and it needs your ownership proven before it credits you with a share.

Three Owners, Same Math

Here is the arithmetic with placeholder figures. The 40% expense factor is chosen only to show the steps. It is not a program figure. Deposits are indexed to 100 so no dollar amounts are needed.

• Owner A, single-member LLC, 100% owner, business account: 100 in average gross deposits, less a placeholder 40% factor, leaves 60. At 100% ownership, the credited income index is 60.
• Owner B, 60% member of a multi-member LLC, business account: 100 in average gross deposits, less the same factor, leaves 60. At a 60% stake, the credited index is 36.
• Owner C, S-corp owner using a personal account: 100 in average eligible deposits, with the expense step usually skipped. The credited index is closer to 100, because the lender treats those deposits as closer to net. Expect questions about how the deposits got there.

Owner C’s number looks best, but that route has its own conditions. Lenders look closely at what is feeding a personal account. Personal deposits that are really business revenue may be treated as a business account anyway.

How Each Entity Type Gets Read

The tax label on your entity changes what the lender asks for. It changes the proof of ownership more than the arithmetic.

(Programs vary on exact documents, so treat this table as the typical pattern, not a checklist.)

The S-Corp Salary Question

An S-corp owner is both an employee and a shareholder. The IRS expects an S-corp to pay a shareholder-employee reasonable pay before it makes non-wage distributions. Your W-2 therefore shows only part of what the business produces. The rest of your profit flows through as distributions and K-1 income.

A tax-return mortgage leans on that salary and the K-1. A bank statement mortgage looks at the deposits. A modest W-2 does not by itself cap your qualifying income.

The mismatch can still draw questions, though. The IRS has described a case where a shareholder took a low salary and large distributions, and the court treated part of those distributions as wages. An underwriter may not care about the tax angle. But a very low salary beside very large deposits makes a reviewer slow down.

The LLC Taxed as an S-Corp

This hybrid trips people up. The LLC is the legal entity. The S-corp is how it is taxed. For income purposes, expect the lender to follow how the business files. Hand over the operating agreement and the K-1, and be ready to explain the structure.

Business vs. Personal Statements

Which account should you use? It depends on where your money actually lands.

Commingling means personal and business money mix in one account. Lenders may treat that account as a business account and apply the expense factor. It is a common surprise. If you pay yourself from business revenue and spend from the same account, clean that up before you apply.

Some programs allow several accounts in the average. Others want the entire average from one account. Deposits should also look plausible for your type of business. A landscaping company with large, round, irregular deposits invites questions.

Deposits That Don’t Count

Before you apply, scan your statements for these. They will likely be removed:

• Transfers between your own accounts
• Refunds and reimbursements
• Loan proceeds or draws
• Owner capital contributions
• One-time sales of equipment, vehicles, or property

Pulling these out of the average lowers the number. But it is better to see that yourself before an underwriter does.

How This Differs From a DSCR Loan

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Bank statement income qualifies you. They answer different questions.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The CFPB’s text on business-purpose credit treats credit to buy or maintain non-owner-occupied rental property as business purpose. That is why a DSCR file on a rental generally doesn’t ask for your personal income, while an owner-occupied file does and follows consumer mortgage disclosure rules.

So where does statement averaging fit for an investor? Mostly in three places:

• A primary-residence purchase or refinance
• A second home
• A file where the lender asks for borrower income anyway

If your goal is only to buy rentals, read Lendmire’s HELOC vs bank statement cash-out vs DSCR for an S-corp or LLC owner. The complete DSCR loans guide covers the property-income side in full.

What Leverage Looks Like

Leverage depends heavily on what the property is used for. Select lenders in Lendmire’s wholesale network typically offer:

• Primary-residence purchase or rate-term refinance: up to 90% LTV on stronger files. LTV, or loan-to-value, is the loan as a share of the property’s value.
• Owner-occupied cash-out (primary or second home): up to 80% LTV, with a fixed expense ratio. An accountant-prepared ratio can improve the setup.
• Asset-depletion alternative on a primary residence: up to about 80% LTV. This is reviewed against liquid assets instead of deposits.
• Investment-property cash-out: tops out around 75% LTV.
• Investment-property purchase on bank statements: varies by lender, so it is better compared against the DSCR side.

Loan sizes generally run from $125,000 to $3,500,000, with reserves commonly around six months of the housing payment. Stronger credit and lower leverage usually widen the options. Terms follow each lender’s program sheet. All of this is subject to lender guidelines, and none of it is a commitment to lend.

Where the General Rule Breaks

• Low pay, big deposits. Your W-2 doesn’t cap the income. A big gap still draws questions, and a short explanation letter helps.
• Partners and minority owners. A 25% owner gets credit for 25%. Your partner’s share is never counted as yours, and some programs set a minimum ownership percentage.
• Multiple businesses. Some programs combine deposits across entities. Others review each separately. Ask before you pick a program.
• Lumpy or seasonal deposits. Averaging smooths them. A recent dip is harder to hide, though, and a longer window can help or hurt depending on trend.
• Property held in an LLC. Statement-based income programs have title rules. Loans to LLC-titled entities are available only subject to program terms, so confirm how the property will be vested before you commit.
• Personal-purpose cash-out on a rental. If you take cash out of a rental to pay personal bills, the file may stop looking purely business-purpose. Say what the money is for.

Here is the honest broker view. The biggest swing factor is the expense method. A certified expense ratio from a CPA can move qualifying income noticeably compared with a default factor. If your business has low overhead, getting a CPA letter before you apply is often the highest-value step. If your overhead is genuinely high, it may not help.

Key Terms Defined

Non-QM: A mortgage outside the standard qualified-mortgage box, often using alternative income documents like bank statements.

Expense factor: The share of business deposits a lender treats as operating costs rather than income.

Ownership percentage: Your share of the business, which sets how much of its income counts for you.

Commingling: Mixing personal and business money in one account.

Lookback: The number of months of statements used for the average, commonly 12 or 24.

DSCR: Debt service coverage ratio, the property’s rent measured against its monthly debt, used to qualify rentals instead of personal income.

Asset depletion: Qualifying from liquid assets by spreading them over a set period into monthly income.

What the Decision Looks Like

Run a quick test. Pull 12 months of statements. Strip out the non-revenue deposits. Check which account holds the revenue. Apply your ownership share. Ask your CPA what a certified expense ratio would look like.

If the result clears your target on the business account, you may not need to change anything. If it only works on a certified ratio, get that letter first. If the property is a rental, run it as a DSCR file and skip your personal income altogether.

Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

A last clarification, because it spreads easily: some people say a 50/50 salary and distribution split is the IRS-approved safe harbor. The Tax Adviser lists that as a myth, since pay should reflect your duties. Statement programs don’t need a magic ratio. They need clean deposits and a story that holds together.
