Large Deposits on a Jumbo Bank Statement Loan: What Underwriters Ask

What counts as a large deposit on a jumbo bank statement loan?

On a bank statement loan, there is no single dollar threshold: every deposit in the window is read, because the deposits are the income. A deposit becomes a question when it does not look like the rest of the account, or when it is the money you will use to close.

The conforming agency guide gives the most widely quoted definition: on a purchase, a large deposit is a single deposit that exceeds 50% of the total monthly qualifying income for the loan, and if those funds are used for the down payment, closing costs or reserves, the lender must document an acceptable source. That rule was written for salaried borrowers, whose accounts are mostly payroll. A business owner's account looks nothing like that. A founder qualifying on $120,000 of monthly income may receive a $90,000 client payment on a Tuesday and think nothing of it.

So Mbanc Private Client Lending, the $1,000,000-minimum desk of Mortgage Bank of California Inc. dba Mbanc, reads a bank statement file deposit by deposit rather than leaning on a percentage trigger. The underwriter asks two separate questions of the deposits, and it helps to know them before your statements are opened. The Founder Loan reads 12 or 24 consecutive months of personal or business statements; the full method is in the bank statement jumbo guide.

What two questions do underwriters ask about a deposit?

First, is this deposit income? Second, if it is part of the money you will use for the down payment, closing costs or reserves, where did it come from? The questions are independent: a deposit can be excluded from income and still be perfectly good money to close with.

The first question decides how much you qualify for. Qualifying income on the Founder Loan is the average of qualifying deposits, so anything that is not earnings is removed before the average is taken. The second question decides whether the funds you are relying on are yours and are not borrowed. A $400,000 transfer from your brokerage account is not income, but with the brokerage statement attached it is the cleanest possible source of a down payment.

How are transfers between your own accounts handled?

They are excluded from income, because money moving from one of your accounts to another is not money earned. The underwriter will match each transfer to its sending account, which is why statements for every account involved belong in the file.

The subtle case is the owner's own pay. Most owners move money from the business operating account to a personal account on a rhythm: a monthly draw, a quarterly distribution, an end-of-year sweep. Whether the file reads those transfers as your income on personal statements, or reads the business account's client deposits instead, is one of the first decisions the banker settles. It decides which statements carry the file and which expense treatment applies. On a personal-statement file, two months of business statements are also reviewed, to show the business is active and that the transfers to your personal account came from it. The choice is discussed in personal versus business bank statements.

What is never allowed is counting the same dollar twice. A $100,000 client payment that lands in the business account and is then swept to your personal account is one $100,000 of income, not two. If you supply both sets of statements, expect the underwriter to trace the sweep and count it once. Owners with several entities face the same issue between companies.

What happens to a one-off deposit in an otherwise steady account?

It is explained or excluded. If it is earnings that will recur in some form, it can stay in the average with an explanation; if it will not recur, it comes out, and the average is taken on what remains.

The distinction is not about size. A consulting firm that bills large milestone payments three or four times a year has lumpy but recurring income, and those deposits are the business. A one-time payment for selling a division, a legal settlement or a tax refund is not part of what the business earns month to month, however welcome it was. For businesses whose income genuinely arrives in waves, see which statement window handles lumpy deposits better.

The way to protect your number is to raise the item yourself. An unexplained outlier invites the underwriter to treat neighboring deposits with the same caution; a one-line explanation with the document attached ends the question.

Do personal and business statements treat deposits differently?

Yes. Personal-account deposits count in full, with transfers between your own accounts excluded. Business-account deposits are first multiplied by your ownership percentage (you must own at least 25% of the business; a sole proprietor or single-member LLC counts as 100%), then reduced by an expense factor: a standard 50%, or a lower ratio set in writing by a CPA, EA or tax preparer, with a floor of 10%, or net income from a third-party-prepared P&L supported by the statements.

That difference changes what a large deposit means. A $250,000 deposit to a business account you own outright becomes $125,000 of qualifying income at the standard factor; at 50% ownership, $62,500. The same $250,000 arriving in a personal account as an owner distribution would be read in full, provided it is not simply the same dollars already counted on the business side. The rules on factors are covered in the expense factor, explained.

Commingled accounts, where personal spending and business receipts share one account, are common in owner-run companies and make the deposit review slower, not impossible. Expect more questions about which deposits are business receipts and which are personal movements. If you can, choose the account that carries the business most cleanly and bring statements for anything that feeds it.

How do you source a large deposit you plan to use at closing?

With the document that shows where the money was before it arrived: the statement of the sending account, a closing statement from a property sale, a trade confirmation, a bill of sale, or, for a gift, a gift letter with the donor's statement. Gift funds are accepted on purchases only, from family members, alongside a contribution of your own that the investor guideline for your file sets; they never count toward reserves and are not permitted on the AR Loan. The goal is to show the funds are yours and are not borrowed.

Funds to close include the down payment, closing costs and required reserves: 3 or 6 months of PITIA (principal, interest, taxes, insurance and association dues) depending on LTV, 9 months on loan amounts over $1,500,000 and 12 months over $2,500,000, liquid after closing and measured on the interest-only payment if the loan is interest-only. Nothing has to move to Mbanc; funds are verified where they sit. See reserves in the private client guide to jumbo loans.

Why are cash deposits harder to document?

Because cash carries no record of where it came from. A wire or a check names its sender; a cash deposit only proves that someone walked into a branch.

That does not make a cash-receipts business ineligible. It means the documentation has to come from the business's own records: point-of-sale reports, daily receipt logs and deposit slips that tie to the statements. Recurring cash receipts consistent with that record can be read as business income where cash is customary to the trade; the guideline does not count cash deposits in a business that would not normally receive them. Large, irregular cash deposits that the records do not explain are the items most likely to be excluded. Cash that has been kept outside an account for years and deposited shortly before closing is the hardest of all to use as funds to close, because there is no trail for the underwriter to follow.

When is a bank statement loan the wrong way to read your deposits?

When the statements are mostly money moving rather than money earned. If most of the volume in the window is transfers, financing draws, capital calls or asset sales, the qualifying average after exclusions may be a fraction of what the account suggests.

• You are paid on 1099s. The Operator Loan qualifies 90% of gross 1099 receipts and avoids most deposit tracing.
• Your strength is the balance sheet. If large deposits are mostly asset sales and portfolio movements, the AR Loan may read you better: eligible assets divided by 84, after funds to close and reserves are set aside.
• You are a salaried borrower with clean returns. A conventional jumbo on your W-2 is usually the better tool. See non-QM jumbo versus conventional jumbo.

How should you prepare your statements before applying?

Read your own statements the way an underwriter will, before anyone else does. Mark every deposit that is not a client payment, and attach its source.

1. Gather 12 or 24 consecutive months for every account in the story, including accounts that only send transfers.
2. List deposits that are transfers, financing, asset sales, refunds or gifts, with the date, amount and the document that explains each.
3. Write one short letter of explanation for anything unusual. Two sentences is enough: what it was, and whether it will recur.
4. Keep the funds you will close with in documented accounts. Avoid large undocumented movements in the months before a purchase.

Then start with a 15-minute call with Mayer Dallal, with no application and no credit pull. Mbanc Private Client Lending will tell you on that call which deposits are likely to count and whether the file is a fit.
