The Quick Read: A bank statement refinance replaces your current mortgage and is reviewed around deposits instead of traditional personal-income documentation. Self-employed owners and investors with heavy write-offs use it most. The underwriter averages 12 months of eligible deposits, applies an expense factor to business accounts, and tests the result against the new payment.
- The loan is reviewed on documented income under the applicable program, subject to lender guidelines.
- Twelve months of personal or business statements is the standard window across the programs Lendmire places files with.
- On an owner-occupied cash-out, leverage tops out around 80% LTV. On an investment-property cash-out, it tops out around 75%.
- Business accounts get an expense factor. Personal accounts are typically counted at full value.
- Occupancy decides the paperwork regime and the loan structure.
Most refinance explainers stop at “it works like a regular refinance with different income proof.” That is true, and it is also where the file problems start. The income math, the occupancy of the property, and the choice between testing you and testing the property all change the outcome. This explainer walks the mechanics in order.

What Is a Bank Statement Loan Refinance?
A bank statement loan refinance pays off your existing mortgage with a new loan that uses deposit history to prove income. It can be rate-and-term, which changes the loan terms without taking equity out. It can also be cash-out, which pays off the old loan and hands you the difference.
Scotsman Guide describes the basic setup. A self-employed borrower with no W-2 supplies 12 to 24 months of personal or business statements. The lender calculates income using a standard expense factor. A profit-and-loss statement or a third-party tax professional’s expense statement is an alternative where the program accepts it.
This is a non-QM product. It sits outside the agency purchase box, and each investor underwrites to its own guidelines. Fewer lenders offer it, which is why borrowers often reach it through a broker. Across the wholesale network, the spread between programs is real: window length, expense-factor rules, and leverage caps all differ by lender.
Who uses it:
- Self-employed owners whose traditional personal-income documentation shows less income than their deposits do.
- Contractors and freelancers with irregular but steady cash flow.
- Investors with heavy write-offs who still want to refinance a personally titled property.
If you qualify on traditional personal-income documentation and the cost is lower, that route usually wins. Bank statement documentation earns its place when returns understate real cash flow.
How Does Underwriting Treat Your Statements, Step by Step?
Underwriting turns deposits into qualifying income in a fixed sequence. Window, deposit screen, expense factor, debt-to-income test, then credit, reserves and property. Each step can move the final number, so the order matters.
1. Pick the statement window and account type. The standard window is 12 consecutive months. Some programs also accept 24 months. Statements may be personal, business, or both, depending on the program. Gaps in the sequence stall files.
2. Screen the deposits. The underwriter totals the eligible deposits and strips out what is not income. Transfers between your own accounts come out. One-off lump sums come out. Large round-number deposits draw questions, so have an explanation and paper ready.
3. Apply the expense factor on business accounts. Rough math: average monthly eligible deposits, times one minus the expense factor, times your ownership percentage. Personal-account deposits are typically counted at full value. The factor depends on the lender and the program. The 50% figure shows up in trade press as an example, but it is a common default, not a rule. Ask for the factor in writing before you pick a program.
4. Convert income to debt-to-income. Qualifying income is measured against the new housing payment plus your other monthly debts. A high DTI is the usual reason a strong-deposit file still fails.
5. Check credit, reserves and the property. Reserves commonly run around six months of the housing payment on these programs. Appraisal and title work like any refinance. On a rental, the appraiser may also complete a rent schedule (Form 1007 for single-family, Form 1025 for 2-4 units).
One refinance-specific point: LTV is measured against the appraised value of the property you already own. Your equity, not a purchase price, sets the ceiling.
How Do Deposits Become Qualifying Income?
Only eligible deposits count, and business deposits are discounted. That is the whole mechanism. The gap between what hits your account and what the underwriter credits is where most surprises live.
Run the numbers this way, with a modeled illustration, not a quote. Say an owner’s business account shows steady deposits, and the program applies a 50% expense factor. Half of the average eligible deposit is credited as income. If the owner has documented a lower expense ratio through a CPA letter or P&L, and the program accepts it, the credited share rises. Without that proof, the file falls back to the default factor.
Three variations change the result:
- Account type. Personal-account deposits are typically counted at full value, while business accounts take the expense factor.
- Ownership percentage. A 60% owner gets 60% of the business income, not 100%.
- Averaging. The 12-month figure reflects your strongest and weakest months together. A 24-month window, where offered, smooths seasonality. A shorter window can show a stronger recent stretch. Which one wins depends on your deposit trend, and declining income draws a trend check under either window.
On owner-occupied cash-out files, the program parameters in the Lendmire network typically apply either a fixed expense ratio or an accountant-prepared expense ratio, and the two are credited differently. That is a different mechanic from the deposit-averaging approach on purchases. Know which regime your file falls under before you compare quotes.
Rate-and-Term vs. Cash-Out: What Changes?
Rate-and-term changes the loan without pulling equity. Cash-out pulls equity and raises the new loan balance. Both can use bank statement documentation, but the leverage ceiling and the occupancy matter far more on the cash-out side.
| Factor | Rate-and-Term | Cash-Out |
|---|---|---|
| Purpose | Change terms or loan type | Pull equity as cash |
| Equity need | Enough to clear the payoff | Enough after payoff and cushion |
| Primary residence ceiling | Up to 90% LTV | Up to 80% LTV |
| Investment property ceiling | Varies by lender | Around 75% LTV |
The 90% figure belongs to primary-residence purchase and rate-and-term files. It does not carry into cash-out. On an owner-occupied cash-out (primary residence or second home), the ceiling is up to 80% LTV, and stronger files earn the top of the range. On an investment-property cash-out, the ceiling is around 75% LTV. Investment purchase leverage on bank statement documentation varies by lender, so treat any single figure with suspicion.
Loan amounts across the network typically run from about $125,000 to $3,500,000, subject to lender guidelines. An asset-depletion alternative, which qualifies from liquid assets rather than deposits, runs up to about 80% LTV on a primary residence.
A worked cash-out frame, in percentages only. Take a primary residence at a given appraised value, with an existing balance well under that value. The new loan can reach up to 80% LTV on the appraised value. The cash to you is the new loan minus the payoff and costs. The calculator on this site can turn that into an illustrative estimate, not a quote. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What Documents Should You Gather?
Gather the statements first, then everything that explains them. Clean statements shorten the list of questions an underwriter has to ask. Messy ones lengthen it.
- Twelve consecutive months of statements for each account used, all pages included.
- A P&L or a CPA-prepared expense ratio if you want a factor below the default and the program accepts it.
- Business ownership evidence, since the ownership percentage drives the credited income.
- Written explanations for large deposits and any transfers.
- Current mortgage statement, insurance declarations, and entity documents if any are in play.
- For a rental, a lease or rent schedule to support the income.
Statement hygiene matters more than most borrowers expect. Commingled accounts force the underwriter to separate personal from business deposits, and the expense factor applies only to the business portion. Contractors with subcontractor pass-through payments may need a higher effective expense factor, or have those deposits excluded. Businesses younger than 24 months can still be reviewed, because underwriters may weigh liquid assets and credit quality alongside the shorter history. That is a lender-by-lender call.
How Does Occupancy Change the Loan?
Occupancy decides which disclosure regime applies and which structure fits. An owner-occupied file is a consumer mortgage, so TRID applies. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. Keep those lines clean in your head. They do not mix.
For investors, the more important question is which test the loan runs. A bank statement refinance tests you: deposits, DTI and credit. A DSCR refinance tests the property: rent against the full monthly obligation, with coverage measured as a ratio. DSCR programs are built around a 1.00x benchmark on many files, though select lenders in the network will review sub-1.00 coverage with adjusted LTV and terms. For a pure rental, DSCR is generally the more direct path. Lendmire’s complete DSCR loans guide covers that side.
Bank statement documentation wins in three situations:
- A thin-coverage rental, such as heavy cash-out on a property with modest rent.
- A primary residence or second home.
- A personally titled property where you want your own income to carry the file.
Scaling matters too. A bank statement loan counts toward your personal DTI, so your income and debts cap how many loans you can carry. DSCR is judged property by property. Entity title is another split: bank statement loans tie to an individual’s income, while DSCR loans often allow LLC title, subject to lender program eligibility.

Is Refinancing This Way Worth It?
Refinance this way when your traditional income documentation understates your real cash flow and the equity or term change justifies the cost. Skip it when tax-return qualification is available and cheaper. Non-QM pricing can run higher than conventional, so the decision is a cost comparison, not a feature comparison.
A simple decision frame:
- Break-even. Add the closing costs to any pricing difference, then compare against what you gain: a lower balance carry, a better term, or access to equity. If the gain does not pay back the costs within the time you plan to hold the loan, pass.
- Use of proceeds. Debt payoff, improvements, and business capital are common. Pulling equity to fund consumption raises the stakes.
- Equity cushion. Cash-out at the ceiling leaves little room if values dip.
- Documentation burden. Twelve months of clean statements is real work if your accounts are commingled.
One tax sentence, since this is not a tax article: tax treatment varies; consult a qualified professional.
Where Does the General Rule Break?
The rules above hold until an edge case hits. These are the ones that move files.
- Missing proof reverts to the default. Claim a lower expense ratio without a P&L or CPA letter and the file falls back to the standard factor.
- Pass-through deposits. Contractors may see those deposits excluded or the factor raised.
- Hybrid income. Some programs let a co-borrower with traditional employment income blend with your bank statement income.
- Refinancing out of a tax-return loan. This switch happens when write-offs have since cut your reported income. The new file uses deposits, so the old return no longer drives the number.
- Refinancing an existing statement loan. The new window resets to current statements, and a declining trend can hurt even if the old loan qualified.
- Short-term rentals. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Key Terms Defined
Expense factor: The percentage of business deposits an underwriter treats as operating costs rather than income.
Eligible deposits: Deposits that count toward income after transfers and one-off lump sums are removed.
Non-QM: A mortgage that falls outside the qualified mortgage box and is underwritten to the investor’s own guidelines.
Rate-and-term refinance: A refinance that changes the loan terms without taking equity out.
Cash-out refinance: A refinance that pays off the old loan and gives you the difference as cash.
Reserves: Liquid funds held after closing, commonly measured in months of the housing payment.
Does Non-QM Mean Less Regulated?
No. A non-QM loan still has to satisfy ability-to-repay. It simply does not get the presumption of compliance that a qualified mortgage gets. The CFPB’s small entity compliance guide says a creditor generally must verify the information it relies on using reasonably reliable third-party records, and that deposited funds count as the consumer’s income if the creditor relies on them. CFS Review’s summary of CFPB supervisory guidance adds that verification records must be specific to the individual, not area averages.
In practice, that is why the underwriter wants statements, not estimates, and why “no documentation” is the wrong mental model. The loan is reviewed on documented income under the applicable program, subject to lender guidelines.
Frequently Asked Questions
Can I refinance an existing mortgage with bank statements?
Yes, on programs that offer it. The new loan pays off the old one, and your income is read from deposits instead of conventional personal-income paperwork. Both rate-and-term and cash-out structures can use bank statement documentation, subject to lender guidelines and occupancy.
How much can I borrow on a cash-out?
On an owner-occupied cash-out, the ceiling is up to 80% LTV, depending on loan size and credit. On an investment-property cash-out, it tops out around 75% LTV. The 90% figure applies to primary-residence purchase and rate-and-term files only. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Do personal and business statements both work?
Yes, on most programs. Personal-account deposits are typically counted at full value, while business-account deposits take an expense factor. Commingled accounts get separated by the underwriter, which adds review work.
Is a bank statement refinance right for a rental property?
Sometimes. DSCR tests the property’s rent against its payment and is usually the more direct path for a pure rental. Bank statement documentation fits when the rent coverage is thin but your personal deposits are strong. Lendmire’s piece Bank Statement Refinance Loan goes deeper on that choice.
Which disclosure rules apply?
Owner-occupied files are consumer mortgages, so TRID applies.
Consumer mortgage availability runs through 16 states, and every file is underwritten individually, subject to lender guidelines. This is not a commitment to lend.
