How to Document a Non-Recurring Deposit on a Bank Statement Loan

The Quick Read: You document a one-time deposit by tracing it to a named source with a paper record, attaching a short letter of explanation, and showing the file still qualifies on the deposits that repeat, because a one-time deposit is usually left out of income even when fully proven. Documentation proves what the money is. It does not turn the money into income.

• Underwriters build a deposit-by-deposit ledger and compare each item to your normal pattern.
• A sourced one-time deposit is typically excluded from income, with no penalty.
• An unsourced deposit is excluded or discounted, which can shrink the qualifying loan amount.
• The same deposit may still matter separately if the money is needed for down payment, closing funds, or reserves.
• Sourcing the outliers before you submit keeps the file moving on the income that remains.

What Counts as a Non-Recurring Deposit?

A non-recurring deposit is money that lands in your account once, or irregularly, and does not reflect the ongoing earning power of your business or job. Think of the sale of a building, a legal settlement, a one-time contract fee, an inheritance, or a loan disbursement.

A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines. Income comes from the average of your deposits over 12 months of business or personal statements, after the lender applies an expense factor. That average only works if the deposits reflect repeatable income. One large item can distort it.

Three categories show up on nearly every file:

• Recurring income deposits. Customer payments, sales receipts, and regular draws. These count, after the expense factor on business accounts.
• Non-recurring income deposits. A real client payment that is unusually large or one-time. These are a judgment call.
• Non-income deposits. Transfers between your own accounts, loan proceeds, refunds, gifts, and insurance or settlement money. These are removed no matter how well documented.

There is no universal dollar threshold for “too large.” Across our wholesale network, the benchmark is your own pattern. A deposit that is a multiple of your normal monthly flow gets flagged. The same dollar amount might pass without a question on a bigger business.

How Does Underwriting Treat It, Step by Step?

Underwriters treat a non-recurring deposit in five steps: list it, flag it, request proof, assign a treatment, and re-run the income without it. The Docsumo overview of bank statement income verification describes the same sequence: strip out non-income items such as transfers and loan proceeds, apply the expense factor to business accounts, then average what remains.

1. Build the deposit ledger. Every deposit across the statement window gets listed.

2. Screen for outliers. Large wires, cash, unfamiliar senders, and spikes above your normal flow get flagged.

3. Request paper. The underwriter asks for whatever traces the money to its origin.

4. Decide the treatment. The deposit is excluded, discounted, or left in income.

5. Re-run the file without it. The question becomes whether the remaining income supports the loan.

That last step is where borrowers get surprised. A flagged deposit rarely ends a file. Most programs we place files with simply remove it and see what the remaining average supports. The result is often a smaller loan amount, not a decline.

The rule behind this is simple. A lender can only rely on income it has verified, and a deposit nobody can identify cannot be assumed to be income. Each lender writes its own screening logic on top of that floor. That is why two programs can treat the same deposit differently.

Which Proof Goes With Which Deposit?

Match the document to the deposit type. The proof establishes where the money came from, and the treatment column shows what usually happens next, subject to the individual lender’s guidelines.

Wires from a sale, an inheritance, or a business distribution need a traceable trail back to the sender. The most common proof is a prior-account statement or a wire confirmation that matches the amount and date.

Three Outcomes, and What Moves a Deposit Between Them

Every flagged deposit ends in one of three places. Knowing which one you are aiming for tells you what evidence to gather.

Moving from the first row to the second costs you nothing and protects your cash-to-close story. Moving to the third row requires more. You must show that the deposit is part of how your business actually earns, not a one-off. A client who pays you every quarter looks lumpy, but the invoices and prior statements show a pattern. A client who paid once does not.

What Does Exclusion Do to the Numbers?

Excluding a deposit pulls the 12-month average back to your true baseline. Include it, and the average rises, which is why underwriters scrutinize it.

Run the numbers as a modeled example, not a market fact. Say eleven months of deposits are all about the same size, and the twelfth month carries one extra deposit equal to a full normal month.

• Included, that extra deposit lifts the 12-month average by about 8%.
• Excluded, the average returns to the baseline.

Now say the one-time deposit equals six normal months of flow.

• Included, the average jumps by 50%.
• Excluded, it again returns to baseline.

The second case is why a lender will not simply take your word for it. A single sale or settlement can make a modest earner look like a high earner on paper. Removing it protects both sides. If your file only works with that deposit counted, the honest answer is that the file does not yet work on recurring income.

How Do You Write the Letter of Explanation?

A strong letter of explanation is short, specific, and backed by an attachment. It has four parts:

1. Date and amount. Match the deposit exactly as it appears on the statement.

2. Source. Name the sender, the account, or the transaction. “Sale of a property I owned” is the start, and the settlement statement finishes the job.

3. Why it is not recurring income. Say plainly that it was a one-time event. Underwriters trust a borrower who volunteers this.

4. The attached document. Reference the proof by name.

Weak letters leave out the source, say “personal funds” with nothing behind it, or claim the deposit is income without showing a pattern. One page is plenty. Do not explain what the underwriter did not ask about, because extra narrative invites extra questions.

Where the General Rule Breaks

The rule that one-time deposits are excluded has real exceptions. These are the ones that come up most.

Business-to-personal transfers. Moving money from your own business account to your personal account is usually stripped out so income is not counted twice. Some programs count a business-to-personal transfer in full when the business statements are the qualifying documents. Treatment varies by program, so ask before you assume.

Cash deposits. These get close review and may be excluded without business records that explain them.

Recurring but lumpy income. Quarterly, annual, and milestone payments look like outliers on a 12-month window. Prior-period statements and invoices can show the pattern. Some lenders in the network will look at 24 months, which smooths out a seasonal business and gives a fairer picture.

Contractors and pass-through funds. Project draws that flow straight out to subcontractors are often screened as pass-through, not income.

Documented but non-income items. A gift, tax refund, or settlement stays out of income even when fully sourced. That is different from an unverifiable deposit, which is excluded because nobody can prove what it is.

Agency-style large-deposit tests. Government-backed programs use their own tests that do not apply to bank statement loans. Do not carry a rule from one lane into the other.

If your question is whether a single unsourced item can sink the file, Lendmire’s piece Does an Unsourced Large Deposit Kill a Bank Statement Loan File? covers that directly.

Does Occupancy Change the Rules?

Yes, because occupancy decides which disclosure regime governs the loan. The deposit logic stays similar, but the surrounding rules differ.

An owner-occupied file, meaning a primary residence or second home, is a consumer mortgage, and TRID disclosure rules apply. On a primary residence, select lenders offer up to 90% LTV on a purchase or rate-term refinance. Owner-occupied cash-out tops out at up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio, depending on loan size and credit. Loan amounts generally run from $125,000 to $3,500,000, and reserves are commonly around six months of the housing payment.

A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. Investment-property cash-out tops out around 75% LTV. Investment purchase leverage on bank statement documentation varies by lender.

Lendmire’s consumer mortgage licensing covers 16 states, so availability on owner-occupied files depends on the property’s state. Every file is underwritten individually, and none of these figures is a commitment to lend.

One note on the sourcing standard: the CFPB’s ability-to-repay compliance guide says a creditor that relies on an inflow of funds must confirm it is the consumer’s personal income. That is why lenders will not count a deposit they cannot identify. The AdviceOnly ability-to-repay glossary summarizes the rule the same way: lenders must consider repayment ability, but the rule sets no fixed deposit number.

Bank Statement or DSCR: Which Lane Fits Your Deposits?

The two lanes qualify different things. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

That difference matters when your deposits are messy. An investor with clean deposits but thin rent coverage may favor the bank statement lane. An investor with lumpy deposits and strong rent may fit better on the DSCR side, where the property drives lender review. Large deposits can still matter for reserves or closing funds in either lane.

Many investors run both options side by side before choosing. The complete DSCR loans guide explains how the property-income lane works.

Pre-Submission Checklist

Run this audit on your own statements before anyone else sees them.

• Pull every page of every statement for the full window, including blank pages.
• Highlight every deposit well above your normal monthly flow.
• Mark every transfer between your own accounts and attach the source-account statement.
• Tag each outlier with its proof from the matrix above.
• Draft one letter of explanation per outlier, each with its attachment.
• Estimate your average with and without each flagged deposit.
• Avoid new unexplained transfers between accounts while the file is under review.
• If you need the money for down payment or reserves, keep the paper trail for that purpose too.

Gather proof before you apply, not after the underwriter asks.

Common Mistakes

• Assuming documentation converts the deposit to income. It proves the source. Treatment is a separate decision.
• Moving money around during review. New transfers create new questions.
• Writing vague letters. “Personal funds” without a trail will not hold.
• Leaving out the second purpose. A deposit excluded from income can still be needed for cash to close, where source documentation is the usual requirement.
• Carrying conventional rules into this lane. Seasoning alone does not replace the paper trail.

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.
