The Quick Read: A bank statement refinance replaces tax returns with 12 months of business or personal deposits as the proof of income, so a self-employed owner whose write-offs shrink the return can still document what the account actually earns. Qualification runs on documented income under the applicable program, subject to lender guidelines, and the file still gets a full review of credit, equity, and reserves.
- Income comes from 12 months of statements, averaged after the underwriter removes transfers and one-time items.
- Business accounts take an expense factor. Personal accounts usually do not.
- Primary-residence rate-term refinances run up to 90% LTV through select lenders. Cash-out on a primary residence tops out at 80% LTV.
- Second-home cash-out runs up to 75% LTV. Investment-property cash-out tops out around 75% LTV.
- Loan sizes run roughly $125,000 to $3,500,000, with reserves commonly near 6 months of the housing payment.

Why Low Tax Return Income Blocks a Conventional Refinance
Traditional personal-income documentation measures taxable income, not cash flow. Depreciation, vehicle costs, home-office deductions, and equipment write-offs all lower net income on a Schedule C or K-1. The business can deposit strong money every month and the return still shows thin income.
A conventional underwriter starts from that net figure. Debt-to-income looks heavy, and the file stalls even though the account balance says otherwise.
A quick self-check: compare the income line on the last return with the average monthly deposits into the account where business revenue lands. A wide gap means the borrower is a candidate for statement qualification. No gap means a standard file probably works.
What Is a Bank Statement Refinance?
It is a refinance where the lender tests deposits instead of taxable income. Experian describes the product as a mortgage for people who can’t provide traditional income documents like W-2s or pay stubs, built on personal or business bank statements.
It is not a loan without documentation. The file is fully documented, just with different records. Across Lendmire’s wholesale network, the programs share one idea: the borrower proves repayment ability from real money moving through real accounts.
Because these are non-QM products, each lender designs its own underwriting rules. The CFPB ATR/QM compliance guide explains that Congress set a presumption of compliance for Qualified Mortgages. Non-QM lenders sit outside that safe harbor and still must make a reasonable ability-to-repay call. That is why expense factors and documentation lists differ from one program sheet to the next.
How Underwriting Treats the File, Step by Step
Here is the sequence on a typical file.
1. Statements collected. Twelve consecutive months of business or personal statements, every page, from the bank, not screenshots.
2. Deposits totaled. The underwriter adds up deposits across the lookback period.
3. Deposits scrubbed. Transfers between the borrower’s own accounts, loan proceeds, refunds, and one-time items come out. Unexplained deposits come out too.
4. Expense factor applied. On business statements, a lender-specific factor reduces the total to reflect operating costs. On the strongest files, a CPA-prepared expense statement can replace the default factor.
5. Averaged. The adjusted total is divided by the months in the lookback to get one monthly qualifying income.
6. Tested against debts. That income goes against the new housing payment and the other monthly obligations on the credit report.
7. Property and title. Appraisal, title work, and payoff of the existing lien run the same as any refinance.
Treat the expense factor as lender-specific. No universal formula exists, and any number a borrower hears before a program is chosen is a guess.
Key Terms Defined
Expense factor: The percentage of business deposits a lender treats as operating cost, so only the remainder counts as income.
Lookback period: The span of statements the lender averages, commonly 12 months in the network’s programs.
Non-QM: A mortgage that falls outside the Qualified Mortgage safe harbor and follows the lender’s own documented underwriting.
Asset depletion: A qualification method that converts liquid assets into monthly income instead of using deposits.
Rate-term refinance: A refinance that changes the rate or term without taking cash out beyond closing costs.
Requirements at a Glance
| Requirement | What it means | How to prepare |
|---|---|---|
| Statements | 12 months, all pages | Download PDFs from the bank |
| Deposit quality | Clean, explainable income | Annotate large or odd deposits |
| Business proof | Tenure and ownership | License, CPA letter |
| Credit | Reviewed by program | Pull a report before applying |
| Equity | Sets the LTV tier | Order no appraisal until a program fits |
| Reserves | Commonly about 6 months | Document liquid assets |
Personal vs. Business Statements
Business statements get an expense haircut and personal statements usually do not. That sounds like personal wins, but it depends on where the money actually lands.
A sole proprietor who deposits everything into a personal account has a simple file. An owner whose revenue arrives through several business accounts has a harder one: the underwriter has to reconstruct income across all of them, and missing a single account can understate the average.
Ownership share matters too. Programs set their own ownership thresholds, and an account the borrower only partly owns may count only in part. Mixing personal and business deposits into one stream muddies the average and invites questions. Pick one clean account type and stay consistent where the books allow it.
Which Deposits Count and Which Get Removed
| Counts | Usually removed |
|---|---|
| Customer payments | Transfers between own accounts |
| Regular business revenue | Loan proceeds |
| Consistent recurring income | Refunds and reimbursements |
| Documented contract income | One-time windfalls |
The CFPB’s concern in this space is that lenders confirm funds are income before relying on them. That is why deposit sourcing matters. A large deposit with a one-line explanation and a supporting invoice moves through review. The same deposit with no explanation gets pulled out.
Fixing this before application is easier than during review. Label unusual deposits, keep a short note for each, and avoid moving money around between accounts in the lookback period.
Credit, Equity, Reserves, and Leverage
Here are the network figures, each tied to its occupancy.
- Primary residence, purchase or rate-term: up to 90% LTV through select lenders. Stronger files earn the top of the range.
- Primary residence, cash-out: up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio.
- Second home, cash-out: up to 75% LTV, set by loan size and credit.
- Investment property, cash-out: tops out around 75% LTV.
- Asset-depletion alternative on a primary residence: up to about 80% LTV.
- Loan amounts: roughly $125,000 to $3,500,000.
- Reserves: commonly about 6 months of the housing payment.
These are typical ranges, subject to lender guidelines. Experian notes these loans can be harder to get because of higher down payment requirements and sometimes higher credit score requirements, which is the same pattern a processor sees in practice: non-QM generally wants more equity than agency loans.
Rate-Term vs. Cash-Out: Occupancy Decides the Program
The loan purpose and the occupancy decide the program, not income alone. A rate-term refinance on a primary residence has the widest leverage. Cash-out always carries a lower ceiling, and the ceiling drops again on a second home or rental.
Occupancy also decides the disclosure regime. An owner-occupied file, meaning a primary residence or second home, is a consumer mortgage and 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 two straight when comparing options, because the paperwork and consumer protections differ.
Special Situations Where the General Rule Bends
Seasonal income. A 12-month lookback captures a full cycle. A borrower with one huge quarter and three quiet ones still averages across all twelve months, so the underwriter sees the whole pattern.
A weak recent stretch. Trend matters. Deposits that run flat or climb over the lookback read cleanly. Deposits that fall sharply toward the end draw questions and sometimes lower qualifying income.
Short self-employment history. Many lenders want a track record of steady self-employment. Programs differ on exactly how long, and some count prior experience in the same field.
Refinancing out of an earlier non-QM loan. A borrower whose returns have improved can sometimes move to a different program later. Equity and credit drive the outcome.
Heavy cash business. Cash that never hits the account is invisible to a statement program. Only deposits count.
Statement Loans vs. DSCR for Investors
The two products test different things. A statement loan tests the borrower’s deposits and stacks every new mortgage onto one income base. A DSCR loan reviews each rental on its own, with qualification resting primarily on property-level rental income covering the payment, subject to lender guidelines.
An investor refinancing a primary residence uses statements. An investor refinancing a rental often does better on DSCR, since traditional income documentation stays out of the equation. Lendmire’s complete DSCR loans guide covers that side in full.
An investor on BiggerPockets was told a loan based on market rents can disregard your income and job altogether. That matches the practical split above, though the thread is several years old and should be read as anecdote only.
Is the Refinance Worth It?
Run three checks before applying.
- Does the new loan meaningfully improve the position, such as pulling equity for a rental purchase or restructuring a heavier obligation?
- Does the leverage tier fit the equity actually available?
- Will the file still make sense if a fresh statement window shows weaker deposits?
Non-QM generally costs more than agency lending, so the refinance has to earn its place. Use Lendmire’s illustrative calculator for rough comparisons, treating the output as an estimate, not a quote.
Why Files Stall or Get Declined
- Missing pages. Every page of every statement, including blank ones.
- Unexplained deposits. They get removed and the average drops.
- Commingled accounts. Personal and business money in one stream.
- Overdrafts and negative balances. They raise questions about stability.
- Unlisted accounts. Revenue in a second business account nobody mentioned.
- Thin reserves documentation. Liquid assets exist but aren’t shown.
Each is fixable before submission. Planning point: if a refinance is coming, talk to the CPA early about the write-off strategy, but don’t change anything solely to game underwriting. Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Can I refinance using bank statements instead of conventional personal-income paperwork?
Yes, through non-QM programs placed with select wholesale lenders. The file is reviewed on documented income under the applicable program, subject to lender guidelines. Credit, equity, and reserves still get reviewed.
How many months of statements are needed?
The network’s programs commonly use 12 months of business or personal statements. Some lenders allow a longer window, and the choice can help when income is seasonal or growing.
Does it work for cash-out?
Yes, with lower leverage than a rate-term refinance. Primary residences reach up to 80% LTV on cash-out, second homes up to 75%, and investment properties around 75%. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Do all deposits count as income?
No. Transfers, loan proceeds, refunds, and one-time items come out, and business accounts take an expense factor. Documenting odd deposits keeps more of them in the average.
Is this the right product for a rental property?
Sometimes. An owner-occupied refinance fits statement qualification. A rental often fits DSCR better because each property is reviewed on its own rent instead of one shared income base.
If you are self-employed and want to see how the numbers work, Lendmire can help you compare bank statement loan options based on your deposits, the property, credit profile, leverage, and your goals. Terms are not a commitment to lend and remain subject to lender guidelines.
