The Quick Read: A bank statement refinance is documented by tying each significant business deposit to an invoice, contract, or payment record, stripping out credits that are not income, and explaining anything unusual in a short letter, so the underwriter can average a clean twelve months of deposits.
- The file is reviewed on documented income under the applicable program, subject to lender guidelines, using 12 months of business or personal statements.
- Paperwork clears underwriting conditions. It does not raise the income number.
- On an owner-occupied cash-out, leverage tops out at 80% LTV (75% with an accountant-prepared expense ratio). On an investment-property cash-out, it tops out around 75% LTV.
- Business deposits are reduced by an expense factor that varies by program and industry.
A quick disambiguation: a “deposit invoice” in the billing world is a bill a business sends for an upfront payment. This article covers the borrower’s side. You are using invoices as proof that money on your statements is real customer revenue.

Key Terms Defined
Bank statement loan: A mortgage that uses your bank deposits, not traditional personal-income documentation, to calculate income. Experian describes these as non-QM loans, meaning loans that fall outside standard agency underwriting boxes.
Deposit averaging: Adding up eligible deposits over the statement period and dividing by the number of months. The result is your monthly qualifying figure before any expense factor.
Expense factor: The share of business deposits a lender assumes goes to operating costs. It varies by program and industry, so no universal formula exists.
Qualifying deposit: A credit that represents earned revenue, such as a customer payment. Loan proceeds, asset sales, and transfers from your own accounts do not qualify.
Unusual deposit: A credit that is much larger than your normal pattern or does not look like routine customer revenue. Underwriters flag these for a source.
Deposit invoice and final invoice: A deposit invoice bills a client for an upfront portion. The final invoice bills the remaining balance and credits the deposit already paid.
Explanation letter: A short signed note that says what a flagged deposit was and points to the supporting document.
Commingling: Mixing personal and business money in one account. It makes business income hard to isolate.
Cash-out and rate-term: A cash-out refinance pays you cash from equity. A rate-term refinance changes the loan’s terms without taking cash out. LTV is the loan balance divided by the property value.
What Is the Underwriter Actually Checking?
The underwriter is asking one question: is this money income, and will it keep arriving? Everything in your package supports that answer.
Four checks do most of the work:
- Consistency. Deposits that arrive steadily month to month read better than one large quarter.
- Source. Each large or irregular credit should trace to a customer, a contract, or an invoice.
- Ownership. The account must be yours, or your business’s, with every page of each statement included.
- Separation. Clean business activity is easier to underwrite than an account that mixes in rent, groceries, and family transfers.
A person reviews the file. That is why a labeled, matched package gets through with fewer follow-up requests than a loose stack of statements.
How Do You Build the Documentation Package, Step by Step?
Build it in seven steps, in this order. Working in order matters because ineligible deposits come out before the expense factor is applied to what remains.
1. Pick the account type. Business statements get an expense factor. Personal statements usually do not, but the deposits must still be identifiable as business income. Some programs let you use whichever type produces the stronger figure.
2. Gather the full statement period. The programs Lendmire places files with are built around 12 months of statements. Experian notes that lenders in general may ask for one to two years of personal or business statements, so confirm which period your program uses. Include every page, even blank-looking ones.
3. List every deposit and label it. Make one row per credit, or one row per recurring client. Mark each as customer payment, transfer, loan proceeds, refund, asset sale, or other.
4. Remove what is not income. Asset-sale proceeds, loan proceeds, gambling winnings, refunds, and one-time transfers between your own accounts come out. Transfers between accounts you own are stripped out, not added.
5. Match the large or irregular deposits to proof. For each flagged credit, assemble the invoice or contract, the statement page with the date and amount highlighted, and a short explanation letter. Lendmire’s piece How to Match Deposits to Invoices on a Bank Statement Loan goes deeper on pairing one invoice with one credit.
6. Apply the expense factor to the remaining business deposits. If your CPA can document a lower actual expense ratio, some programs will consider it. That is a program decision, not an assumption you can make.
7. Submit one organized package. Put the statements, the deposit schedule, the supporting invoices, and the letters together. Label everything by date.
An underwriter who can tie a credit to a document in one glance rarely needs to ask a follow-up question.
Which Deposits Need an Invoice?
Not every deposit needs one. Recurring payments from regular clients can be shown by a pattern, while one-off, round-number, or unusually large credits need a specific document. Use judgment, not a dollar threshold: if you would have to explain it out loud, attach proof.
| Deposit type | Usual treatment | Support to attach |
|---|---|---|
| Regular client payment | Counts as revenue | Invoice or a sample of invoices |
| Upfront client deposit | Counts as revenue | Deposit invoice and contract |
| Transfer from your own account | Removed | Matching debit on the other statement |
| Loan proceeds | Removed | Loan document |
| Customer refund or reversal | Removed or netted | Refund record |
| Asset sale | Removed | Bill of sale |
| Payment-app payout | Counts if tied to customers | Processor report plus invoices |
Treatment varies by program, and the lender makes the final call on every line.
Worked Example: Pairing a Deposit Invoice With Its Final Invoice
Say a remodeling contractor bills a client in two pieces. The deposit invoice asks for an upfront portion at contract signing. The final invoice bills the balance and shows a credit for the deposit already paid.
Two bank credits result: one when the deposit lands, one when the balance lands. To the underwriter, the pair reads as one customer job when the two credits and the two invoices sum to the contract total. The numbers here are illustrative labels only, not program terms.
A matching schedule makes this visible at a glance:
| Invoice | Client | Invoice date | Deposit date | Amount note |
|---|---|---|---|---|
| Deposit invoice 101 | Client A | Contract signing | Within days | Equals the invoiced deposit |
| Final invoice 101 | Client A | Job completion | Later month | Equals balance after credit |
| Invoice 102 | Client B | Mid-month | Same month | Equals invoice total |
| Invoice 103 | Client C | Month-end | Next month | Equals invoice total, timing noted |
A short explanation letter for an unusual credit can be this simple:
The deposit on the highlighted date is a payment from Client A under the attached contract. It is the first of two payments for the same job. The attached invoices show both amounts, and the second payment appears on a later statement.
Timing mismatch is the usual reason a match looks off. Revenue you billed is not cash you received. A job billed in one month may be paid in the next, and the schedule should show both dates so the underwriter sees the delay is normal.
Where the General Rule Breaks
The matching approach works for most files. These situations bend it.
Payment apps and processors. Deposits from a processor often arrive net of fees, or they look like personal transfers. Bridge them with the processor’s payout report and the invoices behind each payout.
One payment covering many invoices. A client may pay several invoices at once. List the invoices together on one schedule row and show that they sum to the credit.
Early and late payments. A client may pay before you invoice, or weeks after. Date both events on the schedule.
Subcontractor pass-through. This is the pattern most likely to force an adjustment on a contractor’s file. If the money moves straight through to subs, invoices showing the pass-through help the lender decide what to count. Some or all of those deposits may be reduced or set aside.
Commingled accounts. When personal and business activity share one account, income is hard to isolate. Separating the activity before you apply makes the file cleaner.
Cash and informal clients. Without an invoice, substitutes include a contract, emails confirming the work, or a processor report. A deposit that cannot be tied to any source risks exclusion.
Large one-off deposits. Document them with the sale or contract behind them. A documented jump is either counted or set aside as a one-time event.
Accountant letter versus profit-and-loss statement. An accountant-prepared expense ratio can replace the default factor on programs that allow it. On owner-occupied cash-out, the 80% LTV ceiling drops to 75% when the accountant-prepared ratio is used. A profit-and-loss path usually carries its own cap under program rules.
Newer businesses. A short history does not automatically disqualify a file, but it typically calls for stronger compensating factors such as credit, reserves, or lower leverage.
What Changes on a Refinance?
The deposit documentation itself works the same way on a refinance as on a purchase. The differences come from the leverage ceiling, the occupancy, and the paperwork regime around the loan.
Leverage depends on the transaction and the property. On a primary residence, a purchase or rate-term refinance can reach up to 90% LTV through select lenders, with the strongest files earning the top of the range. An owner-occupied cash-out on a primary residence or second home tops out at 80% LTV. An investment-property cash-out tops out around 75% LTV. Investment-property purchase leverage on bank statement documentation varies by lender, so treat it as a case-by-case answer. Loan amounts generally run from $125,000 to $3,500,000, and reserves commonly run around six months of the housing payment. All of this is subject to lender guidelines, credit, and loan size.
Occupancy decides the disclosure regime. An owner-occupied refinance is a consumer mortgage, so TRID disclosure rules apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. Know which one your property falls under before you compare options. Payment and rate figures live only in the calculator, which gives an illustrative estimate.
Verification is not optional. The CFPB’s Ability-to-Repay compliance guide lists bank statements among the records that can verify income, and it says a creditor must verify the income or assets it relies on. Relying on deposits nobody has identified is a verification problem. A lender also does not have to verify income beyond what it needs to support repayment, per the CFPB’s small entity compliance guide. That is why a lender can leave unexplained deposits out and still approve the file on the remaining income.
Cash-out proceeds. Keep clear records of how you use the funds. 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.
When a DSCR Loan Fits Better
If you cannot document the flow of money, or your deposits are messy but your rental property is strong, a DSCR loan may fit better. DSCR stands for debt service coverage ratio, and it compares the property’s rent to its monthly obligation. 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.
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines, and it looks at your deposits, credit, and debt load. The right product is the one with the cleaner paper. For the full picture, see Lendmire’s complete DSCR loans guide.
Another alternative is asset depletion, which is reviewed against liquid assets instead of deposits. On a primary residence it runs up to about 80% LTV on select programs. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Pre-Application Checklist and Common Mistakes
Before you apply, work through this list:
- Pull every statement page for the full period, with no gaps.
- Open a deposit schedule and label every credit.
- Move personal activity out of the business account.
- Gather invoices or contracts for large, round, or irregular deposits.
- Trace each internal transfer from the debit on one statement to the credit on the other.
- Write a short letter for each unusual credit.
- Ask your accountant whether a prepared expense ratio is available and allowed.
The mistakes that cost the most are predictable:
- Assuming every deposit counts.
- Assuming business deposits count in full.
- Treating more paperwork as more income.
- Leaving a large deposit unexplained and hoping nobody notices.
- Handing over self-certified numbers with no records behind them.
Documentation reduces underwriting conditions. It does not raise the coverage figure.
Frequently Asked Questions
Do I need an invoice for every deposit?
No. Recurring client payments can be shown by a clear pattern, often with a sample of invoices. Large, round, irregular, or first-time deposits need a specific document, and any credit you would struggle to explain should have one.
What if a client paid me in cash?
Cash deposits still need a source. A contract, emails confirming the work, or a signed receipt can stand in for a formal invoice. A cash deposit with no support risks being excluded from the average.
Do deposit invoices count differently from final invoices?
They count the same way, as customer revenue, once both are tied to the same job. The underwriter wants to see the deposit and the final payment as one project, which is why the final invoice should show the credit.
Can accounting reports replace bank statements?
Not by themselves. Accounting reports show what you billed, while statements show what you received. They can explain a deposit, but the statements remain the record the lender relies on.
Is a bank statement refinance available everywhere?
Consumer bank statement programs are available in 16 states, and the details vary by lender. Lendmire arranges these loans as a broker through select lenders, and every file is underwritten individually.
