How Much a Bank Statement Mortgage Lends a Self-Employed Contractor

The Quick Read: The loan amount comes from your average monthly deposits, trimmed by an expense factor and your ownership share, then tested against your debts, the property payment, your credit, and a leverage cap that depends on how you will occupy the home. No single number applies to every contractor, because each lender sets its own expense factor and its own limits. Lendmire arranges these loans through select lenders in its wholesale network, and every file is underwritten individually.

• Qualifying income comes from deposits, not from the net profit on your tax return.
• The expense factor is the biggest lever, and an accountant-prepared ratio can change it.
• On a primary residence, purchase and rate-term leverage reaches up to 90% LTV through select lenders.
• Cash-out caps are lower: up to 80% on a primary residence, up to 75% on a second home or an investment property.
• Loan sizes run roughly $125,000 to $3,500,000, with reserves commonly around six months of the housing payment.

What Is a Bank Statement Mortgage, and Why Do Contractors Use It?

A bank statement mortgage swaps tax-return income for deposit history. The lender reads 12 months of business or personal statements, averages the eligible deposits, and builds qualifying income from that average. It is reviewed on documented income under the applicable program, subject to lender guidelines.

Contractors use it because write-offs cut the income on a tax return. Truck costs, tools, depreciation, and subcontractor payments all lower net profit. A conventional lender sees that lower number. A deposit-based lender sees the cash that actually moved through the account, then adjusts for the cost of earning it.

This is still full underwriting. Credit, reserves, debts, and the property all get reviewed. It is not a judgment on your credit.

Tax treatment varies by borrower and situation; consult a qualified tax professional.

Key Terms Defined

Expense factor: The share of business deposits the lender treats as the cost of doing business, so only the remainder counts as income.

Eligible deposits: Deposits that look like real business or personal earnings after transfers, refunds, loan proceeds, and one-time items are removed.

Ownership share: The portion of the business you own, which limits how much of the income counts for you.

Debt-to-income ratio (DTI): Your monthly debts, including the new housing payment, divided by your qualifying monthly income.

LTV (loan-to-value): The loan amount as a percentage of the property’s value or price.

Reserves: Liquid funds left after closing, commonly around six months of the housing payment on these programs.

DSCR: A ratio that compares a rental property’s income to its monthly obligation, so the property is tested rather than the borrower’s personal income.

How Do Deposits Become Qualifying Income?

Deposits become income through a short sequence: pick the account, scrub the deposits, apply the expense factor, prorate by ownership, then test the result. Each step can move the final loan amount.

1. Choose the account. Use business or personal statements, whichever shows how you actually run your money. The program guideline decides how each is treated.

2. Collect every page. Lenders want all pages of consecutive statements for every account used.

3. Scrub the deposits. Transfers between your own accounts, loan proceeds, refunds, gifts, and one-time items come out.

4. Apply the expense factor. Business-account deposits are cut by a factor, because revenue is not profit. Personal-account deposits are generally counted closer to face value.

5. Prorate by ownership. If you own part of the company, only your share counts.

6. Average over the window. The adjusted total is divided by the number of months in the statement period.

7. Test the result. The resulting income is checked against debts, credit, reserves, and the property.

The formula in words: eligible deposits, minus the expense factor on business accounts, times your ownership share, divided by the months in the window. The factor varies by lender and business type, so the same statements can produce different incomes at two lenders. Across the wholesale network, the strictest overlays want closer documentation, while others accept an accountant’s letter in place of a fixed factor.

Here is how the pieces fit, using index points instead of dollars. Say your average monthly deposits are 100 points. After scrubbing transfers and one-time items, 92 points remain. Qualifying income on a business account is then 92 times one minus the factor. If a different lender’s factor is 10 percentage points lower, qualifying income rises by about 9 points, roughly a tenth of your deposits, from identical statements. That swing flows straight through to the loan size.

Federal ability-to-repay rules require lenders to verify income from third-party records. The CFPB’s ability-to-repay and qualified mortgage compliance guide lists bank account statements among acceptable records. A bank statement loan therefore sits outside the qualified mortgage box without being a stated-income loan.

The Three Gates: Income, Leverage, and Program Range

Three limits cap the loan: your income and debts, the leverage cap for the property type, and the program’s loan-size range. For most contractors, income and DTI bind first on a purchase, while the leverage cap binds first on a cash-out.

Gate one is income and debts. Qualifying income, multiplied by the lender’s DTI limit and reduced by your existing debts, leaves a monthly housing budget. That budget supports a maximum loan. Paying off a truck loan or a card balance frees more of that budget than most borrowers expect.

Gate two is leverage. The LTV cap sets the maximum loan against the price or value. Even with strong income, you cannot borrow above the cap. A bigger down payment helps only if income is not the tighter limit.

Gate three is program range. Loan amounts on these programs run roughly $125,000 to $3,500,000. Below the floor, other products fit better. Above the ceiling, a jumbo or portfolio structure is needed.

Reserves sit alongside the three gates. Lenders commonly look for around six months of the housing payment in liquid funds. A contractor with lumpy income who holds thin reserves can be declined even when the income math works.

What Leverage Caps Apply to Each Occupancy Type?

Leverage depends on the transaction and on occupancy. Each cap below is a typical ceiling through select lenders in Lendmire’s network, subject to lender guidelines, credit, and loan size.

Stronger files earn the top of each range. Credit score and loan size both pull the cap down, and the 90% figure applies only to a purchase or rate-term refinance on a primary residence.

The accountant-prepared ratio is a real tradeoff on a cash-out. It can show a lower true expense burden, which lifts income, but the program caps leverage at 75% instead of 80%. If income is your binding gate, the accountant route may win. If leverage is binding, the fixed ratio may serve you better. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

The asset-depletion alternative is reviewed against liquid assets rather than deposits. It tops out around 80% on a primary residence. It suits a contractor who has built a large cash or brokerage balance but has uneven monthly deposits.

Which Statements Should a Contractor Use?

Use the account where your real business revenue flows, and keep it clean. A contractor who runs everything through a dedicated business account usually gets the most straightforward file. A contractor who pays business costs from a personal account may do better with personal statements, because personal deposits are generally counted closer to face value.

Commingled accounts cause the most trouble. When business deposits, family transfers, and personal spending mix together, the lender has to sort them out line by line. That slows review and lowers approval odds.

Contractor type matters too:

• General contractors collect client money and then pay subcontractors and suppliers. Gross deposits overstate what stays with the owner, so expect closer expense scrutiny. An accountant-prepared ratio may reflect the true margin better than a fixed factor.
• Subcontractors often have a clean deposit pattern from a few payers. Some programs use gross 1099 earnings instead of bank deposits, and the factors differ across lenders, so ask which approach fits.
• Owner-operators with seasonal work should look at which 12 months the lender will read. A strong summer and a slow winter average out, but a clearly falling trend does not.

Falling deposits are the classic red flag. A lender looking at 12 months will compare the first half to the second half. If recent months run well below the average, the lender may use the lower figure or ask for an explanation. When that happens, a DSCR loan, which looks at the property’s rent rather than your personal income, can be the easier path for an investment purchase.

Where Does the General Rule Break?

The rule that deposits set the loan breaks in four places: occupancy, partial ownership, investment purchases, and thin or declining deposits.

Occupancy changes the disclosure regime. An owner-occupied file, meaning a 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. Under the federal rule’s business-purpose exemption, credit extended primarily for a business or commercial purpose falls outside the consumer rules. Not every investment property is automatically exempt, though. As a compliance trade explainer notes, the purpose of the loan matters, not just the property type.

Partial owners get partial credit. If you hold 50% of the business, only half of the adjusted income counts for you. Documenting a larger share, where it is accurate, raises the number. Misstating it never works.

Investment purchases vary by lender. Not every bank statement program offers an investment purchase option, and leverage on one differs from lender to lender. Investment cash-out tops out around 75% LTV. For investor-focused leverage on a purchase, the DSCR side of the platform usually gives clearer guidance.

Thin deposits are not fixed by a bigger down payment. If income is the binding gate, adding cash lowers the loan amount you need, but it does not raise the amount the lender will extend against your DTI. The honest options are to improve the income documentation, pay down debt, or choose a different product.

Bank Statement or DSCR: Which Fits a Contractor Who Buys Rentals?

A bank statement loan draws on your personal income every time. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. For a contractor adding rentals, that difference matters more than any expense factor.

Every new mortgage payment on a bank statement file eats into the same DTI. By the third or fourth property, personal income becomes the constraint, even for a busy contractor. DSCR judges each property on its own rent, which is the main reason investors scale with it. That is the same point made in Lendmire’s complete DSCR loans guide.

A bank statement loan wins when the property’s rent is thin but your deposits are strong. It also wins for a primary residence or a house-hack, where owner occupancy opens the highest leverage caps. Programs below 1.00 coverage are available through select DSCR lenders in the network, but leverage and terms adjust, so a thin-rent property does not automatically push you away from DSCR either.

How Can a Contractor Raise Borrowing Power Before Applying?

You can raise the loan amount by cleaning up the file before the lender sees it. These steps are ordered by how much they typically help.

• Document real expenses through a CPA. An accountant-prepared ratio can replace a fixed factor on programs that accept it. Weigh the leverage tradeoff on cash-outs.
• Separate your accounts. Run business revenue through one business account and stop mixing personal spending into it.
• Stop moving money between your own accounts in the statement window. Transfers get excluded, but they also clutter the review.
• Pay down revolving debt and vehicle loans. Each debt eliminated frees DTI room.
• Deposit consistently. Route all client payments through the account. Cash that never reaches a statement does not count.
• Build reserves. Aim for the roughly six months of housing payment that programs commonly look for.
• Time the application. If your deposits are trending up, apply when the 12-month window shows the strongest picture.

Lendmire’s team can read your statements the way a lender would, before you apply. The practitioner insight here is simple: most contractors lose more loan amount to messy deposits than to the expense factor itself.

What Are the Limits and Tradeoffs?

Bank statement loans often cost more than conventional loans, which is the trade for flexible documentation. If your traditional personal-income documentation already shows enough income, a conventional loan may be the better call. The flip point is a return where write-offs have cut net income below what the housing budget needs.

Lenders also differ. Two programs can read the same statements and return different amounts, because each sets its own expense factor and DTI limit. That is why comparing several lenders on one set of statements matters more than optimizing for any single guideline.

Finally, term length follows each lender’s program sheet. Describe your preferred term to your broker, but do not assume a 40-year or interest-only option exists on bank statement files. Those structures are DSCR-side offerings.
