How to Document a Bank Statement Mortgage as a Home Builder or Contractor

The Quick Read: Start with twelve months of clean statements, decide which account carries your income, and pull every non-income deposit out of the stream before a lender does it for you. The underwriter averages what is left and applies an expense factor if the account is a business account. Most of the work is sorting deposits and proving the business is real.

• Twelve months of consecutive statements, business or personal, is the typical documentation window.
• Business accounts take a lender-set expense factor. A third-party accountant’s ratio can support a better one, where the program allows it.
• Owner transfers, loan proceeds, refunds and customer deposits for work not yet started are the usual flags.
• Primary-residence purchase and rate-term loans reach up to 90% LTV through select lenders. Owner-occupied cash-out tops out at 80%.
• Credit, reserves, other debts and the property are reviewed on every file. Qualification is subject to lender guidelines.

Builders and contractors are the borrowers this product was made for. Write-offs, job-based cash flow and draws that swing month to month make traditional personal-income documentation a poor picture of what comes in. Bank statements show it. They also show everything else, which is where files get into trouble.

What a Bank Statement Mortgage Is

A bank statement mortgage qualifies the borrower on documented income under the applicable program, subject to lender guidelines. Instead of traditional personal-income documentation, the lender reads your deposits. It is a documented loan. The evidence just changes.

Across Lendmire’s wholesale network, the typical file runs on twelve months of statements. Loan sizes run roughly $125,000 to $3,500,000, and reserves commonly sit around six months of the housing payment. Asset-depletion is an alternative for borrowers with large liquid balances, reaching about 80% LTV on a primary residence.

One point decides which rules apply: occupancy. A loan on your primary residence or second home is a consumer mortgage, and TRID disclosures apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. The two are different files. Keep them separate in your head and in your paperwork.

Key Terms Defined

Qualifying deposits: Deposits that count as business or personal income after transfers, refunds and loan proceeds are removed.

Expense factor: The percentage of business-account deposits a lender treats as operating cost rather than income. The lender sets it.

Pass-through money: Funds that come in from an owner or client and go straight out to subs and suppliers. It is not your earnings.

Non-QM: Mortgage programs that sit outside standard agency guidelines and set their own documentation rules.

Seasoning: The ownership period required before cash-out on a recent purchase.

Why Contractor Income Needs a Different Read

Contractor deposits are noisy. A general contractor collects a draw from an owner, then pays framers, electricians and the lumber yard from the same account. Gross deposits can look far larger than real earnings.

Underwriters know this. The pattern most likely to trigger a lower qualifying figure is large pass-through volume with no explanation. Trades with heavy material and labor costs tend to draw higher expense factors than service businesses.

That is not a reason to avoid the product. It is a reason to document the account so the lender can see what is revenue and what is a pass-through.

Which Account Carries the Income?

Personal statements are generally counted on net eligible deposits, without an expense factor. Business statements start from gross revenue, and the lender applies a factor. Whether mixed accounts are allowed varies by lender. Most programs in the network limit or bar them. A few will take them with extra sorting.

If you have a choice, one clean account beats two messy ones. Route income into it and move money out by transfer. Do that before the statement window opens, not during it.

The Documentation Checklist

Grouped by what the lender is trying to confirm.

Income evidence

• Twelve consecutive months of statements, every page, including blank pages.
• A third-party accountant’s expense ratio or letter, if you want to support a lower factor.
• 1099s or a third-party P&L, if the program accepts them as support.

Business proof

• A business license or trade license.
• Entity documents if you operate through an LLC or corporation, subject to lender program eligibility.
• A letter from a CPA or tax preparer confirming the business and your ownership.
• A history in the trade. Roughly two years is a common expectation. Newer businesses are often harder, not automatically out.

Assets and funds

• Statements for down payment and reserves accounts.
• Sourcing for any large deposit into those accounts.

Personal and transaction

• ID and credit authorization.
• Purchase contract, or current mortgage and insurance details on a refinance.
• Other debts. Bank statement qualifying changes the income number. It does not remove debt-to-income review.

A self-prepared P&L is the usual weak spot. On owner-occupied loans, the lender must rely on reasonably reliable third-party records, which the CFPB’s small-entity compliance guide says can include bank statements and generally excludes borrower say-so. A P&L you wrote yourself rarely carries weight. Use a third party.

How the Underwriter Reads Your Deposits

The steps are mechanical. Here is the sequence.

1. Total the statements. The underwriter pulls every deposit across the twelve months.

2. Strip non-income deposits. Transfers between your own accounts, loan proceeds, refunds, LLC capital contributions and one-time windfalls come out.

3. Average the remainder. Eligible deposits are totaled and divided by the number of months.

4. Apply the expense factor. On business accounts only. The lender sets it from business type and documentation. A lower factor generally needs support, like an accountant’s letter.

5. Adjust for ownership. On multi-owner firms, qualifying income follows the borrower’s ownership percentage.

6. Check the trend. Stable or rising deposits help. A declining trend can pull the figure down.

7. Review the full file. Credit, reserves, other debts and the property. On owner-occupied loans, the lender’s duty to make a reasonable repayment determination, set out in the CFPB’s ability-to-repay rule, still applies. The rule does not fix a debt-to-income cap, so tolerance varies by program.

Deposit Audit: What Counts and What Gets Flagged

The deposits that cost contractors the most are the ones they never labeled. A short note beside each large or unusual deposit saves a conditions round later.

Worked Example: Reported Profit Versus Deposits

This is a modeled comparison, not a quote and not a market figure.

Picture a builder whose tax return shows modest profit after heavy write-offs. Twelve months of business statements show strong gross deposits. After the underwriter removes transfers and one loan draw and applies the lender’s expense factor, qualifying income lands well above the return’s figure. That gap is the reason the product exists.

Now add an accountant-prepared expense ratio showing real costs below the lender’s default factor. Where the program accepts it, the factor can improve and so can qualifying income. On owner-occupied cash-out, the network uses a fixed expense ratio, or a different ratio when an accountant prepares it, and leverage goes up to 80% LTV on a primary residence or second home. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Run it the other way too. If most deposits are pass-through draws, the factor and the exclusions can shrink the number sharply. The builder in that situation often does better with separate project accounts, or with the CPA letter.

Explaining the File

Underwriters read explanations. Short ones work best.

• Large deposit letter: Date, amount, payer, project, and the invoice or contract that backs it.
• Pass-through letter: State that owner draws fund subs and suppliers, list the account that pays them, and attach a recent job summary.
• Business narrative: Years in the trade, entity type, ownership share, current jobs and pipeline, in a few plain lines.
• Accountant’s letter: It should confirm the business, your ownership percentage and, where the program allows, the expense ratio. No CPA yet? A third-party tax preparer can often fill the role. Ask the lender which credentials it accepts.

Preparation Timeline

Work backward from the day the statement window opens.

Ninety days out: Pick the primary account. Stop mixing personal and business money. Pay down revolving balances that drag on debt-to-income.

Sixty days out: Route all job income through the chosen account. Move owner draws out by transfer only. Request the accountant’s letter.

Thirty days out: Pull every statement and read them as an underwriter would. Mark each deposit that is not plain revenue. Write the explanation letters. Gather business license, entity documents and asset statements.

Before you submit, confirm every page is present, every NSF or overdraft has an explanation, and large deposits into reserve accounts are sourced.

Where the Rule Breaks

Newer businesses. Under about two years in the trade is often an obstacle. It depends on the lender and on compensating strength in credit and reserves.

Seasonal gaps. A slow winter lowers the average. Twelve months captures the full cycle, which can help builders in seasonal regions.

Blended income. A paycheck deposited into the same account has to come out of the deposit stream so it is not counted twice.

Partial ownership. Qualifying income follows your share. Have the ownership percentage documented in writing.

NSF and overdraft activity. Repeated events draw questions and can cost leverage.

Credit events. Waiting periods after a bankruptcy or foreclosure vary by program.

Choosing the Right Product

Bank statement loans qualify your income. DSCR loans qualify the property’s rent. A builder buying a primary residence uses the first. A builder buying a rental often does better on the second, because contractor income is lumpy and heavily written off, and DSCR looks at the property alone.

On cash-out, the numbers differ. Owner-occupied cash-out on a primary residence or second home reaches up to 80% LTV. Investment-property cash-out on bank statement documentation tops out around 75% LTV. Investment purchase leverage on this documentation varies by lender, so investors weighing a rental purchase should compare it against the DSCR side. Lendmire’s piece P&L Loan vs Bank Statement Loan for a Contractor or Home Builder covers the alternatives in more detail.

Construction financing is a separate loan. Statements support the permanent mortgage. A builder who is building their own home usually sequences construction financing first and the permanent loan after, and the permanent loan then is reviewed on documented deposits.

Term length follows each lender’s program sheet. Do not assume extended or interest-only terms on a bank statement file.
