Do Big Banks Keep Bank Statement Loans In-House?

The Quick Read: Mostly no. Large national banks rarely offer statement-documented loans at volume, and the ones that do often sell or securitize them rather than hold them on the balance sheet. The loans mostly come from non-bank specialty lenders, with a few mid-size banks, savings banks and credit unions holding them for relationship borrowers.

• “Bank statement” describes how income is documented. “Portfolio” describes who keeps the loan. A loan can be both, either, or neither.
• Large banks lean toward standardized loans that fit agency and prime jumbo boxes.
• Non-bank lenders and brokers with wholesale access are where most statement-based files actually land.
• Exceptions exist, so the useful move is to ask a lender directly what it holds, sells and services.

What Does “In-House” Actually Mean?

“In-house” gets used for four different things, and mixing them up causes most of the confusion on this topic.

Originating means taking the application and making the loan. Underwriting means reviewing the file and deciding. Holding means keeping the loan on the lender’s own books after it is made. Servicing means collecting payments afterward.

A lender can do all four. It can also underwrite a file itself and then sell the loan the same week. Some lender web pages call direct underwriting “in-house,” which has nothing to do with whether the loan stays on their books. When you ask whether a bank keeps these loans in-house, you are really asking about holding, and sometimes servicing.

Why Most Big Banks Pass

Big banks mostly pass because statement analysis is manual and judgment-based, and large institutions prefer standardized underwriting that scales. That is a commonly cited reason, not a rule.

Capital treatment and legal exposure also play a part. A non-QM mortgage REIT’s securities filing states that banks do participate in non-QM, but private capital lenders have historically held the larger share. It adds that larger banks typically write non-QM when a strong customer relationship exists, and that they have concentrated on agency and prime jumbo lending. Treat that as one company’s stated view from several years ago, not a regulator’s finding. It still fits what Lendmire sees across its wholesale network: large banks are rarely where a self-employed borrower’s statement file ends up.

Where do the loans go instead? Academic work from Berkeley Haas notes that private-label mortgage securities tend to be backed by loans that don’t meet agency documentation rules, which is to say non-QM. So the typical path is origination by a specialty lender, then a sale or securitization. Industry coverage from American Banker’s ASReport describes the same shift, with private credit and non-depositories filling the non-agency space as banks pull back. That reporting is a couple of years old, so read it as direction rather than a current share.

Who Does Keep Them?

Mid-size and community banks, savings banks and credit unions are the most likely holders, and non-bank specialists are the most likely originators. Policies change, and none of these categories is uniform.

One caution: a broker has an interest in this answer. A broker arranges loans through lenders and is paid when a file places. The table is a pattern, not a promise about any single institution, and the way to check is the question list further down.

Bank Statement Loan, Portfolio Loan, Non-QM: Three Labels, Three Questions

These terms overlap but answer different questions.

• Bank statement loan: how income is documented.
• Portfolio loan: who keeps the loan after it is made.
• Non-QM: whether the loan falls outside the qualified-mortgage box.

A bank statement loan is usually non-QM. It can be portfolio if a bank holds it. A portfolio loan can use full tax-return documentation and have nothing to do with statements. Portfolio products tend to come from smaller community banks and credit unions, and they are generally for borrowers with unusual circumstances, since not every lender offers them.

How a Statement File Actually Moves

Across Lendmire’s wholesale network, the sequence is consistent from lender to lender:

1. The borrower provides 12 months of business or personal bank statements.

2. The underwriter filters out transfers and other non-income deposits, then averages the rest.

3. On business statements, a lender-specific expense factor estimates net income. Factors vary by program, so no universal formula applies.

4. The property is appraised.

5. The loan is held by the lender or sold to an investor.

If the lender keeps the loan, its own credit policy governs. If the loan is sold, the buyer’s guidelines govern. Most non-bank lenders publish guideline matrices, which is one reason a broker can compare several at once.

Qualification here means the borrower is reviewed on documented income under the applicable program, subject to lender guidelines.

A Worked Example

Picture a business owner with a thriving company and heavy write-offs. The tax return shows modest net income because depreciation and expenses shrink it. Business deposits tell a different story.

A large bank reviewing the return alone may find the income too thin. The owner asks about statements and is told the bank doesn’t offer them, or only to existing high-balance clients. The owner then goes to a specialty lender, or to a broker who can compare several.

Under a bank-statement program, the lender averages 12 months of deposits and applies an expense factor. Leverage on a primary residence purchase or rate-and-term refinance can run up to 90% LTV through select lenders, with the strongest files earning the top of that range. Loan sizes in the network typically run from $125,000 to $3,500,000, and reserves commonly sit near six months of the housing payment. All of it is subject to lender guidelines, credit, and property review.

What Changes by Occupancy

Occupancy decides which rulebook the loan lives under, and it also changes the leverage.

Owner-occupied files, meaning a primary residence or second home, are consumer mortgages. On an owner-occupied cash-out, the ceiling is typically up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio, depending on loan size and credit. That is a cash-out figure, not the purchase ceiling.

A loan on a non-owner-occupied rental, including a short-term rental, is a business-purpose investor loan, and the consumer disclosure rules that cover owner-occupied loans generally don’t apply to it. Investment-property cash-out on bank-statement documentation tops out around 75% LTV. Investment purchase leverage varies by lender, so treat any single number with suspicion.

The regulator’s own wording matters here. The CFPB’s official interpretation of Regulation Z says the creditor must determine the primary purpose in each case, with special rules for owner-occupied rental property. Purpose of the proceeds governs, not the collateral alone.

If qualifying on liquid assets suits you better, an asset-depletion alternative can reach about 80% LTV on a primary residence. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

When a Bank Statement Loan Is the Wrong Tool

Statements fit an investor with strong deposits and low taxable income who is buying or refinancing a home they will live in. For a pure rental purchase, they are often the wrong lane.

DSCR loans qualify primarily on property-level rental income covering the payment, subject to lender guidelines. If you want the rent, not your personal income, to carry the loan, the DSCR route avoids the statement-averaging step altogether. Lendmire’s complete DSCR loans guide walks through that structure. For a beach house or second property where both options are on the table, Lendmire’s piece STR DSCR vs Bank Statement Loan for a Beach House covers the tradeoff.

Industry reporting from HousingWire cites a bank-securities-arm projection that non-QM originations rise from $108 billion to $175 billion, driven by DSCR and investor loans. That is a projection, not a result.

How to Check What Any Lender Does

Ask these five questions before spending time on an application:

• Do you hold your non-QM loans or sell them?
• Who services the loan after it funds?
• Is the file underwritten by a person, or by an automated template?
• How do you treat business versus personal deposits?
• Does my occupancy type fit the program?

A lender that can’t answer the first one clearly may not run the program at all. Many investors lose time applying with a bank that declines non-standard income after a long review.

If a Big Bank Is Your Only Option

Start by asking whether the private-banking or relationship desk writes anything outside the agency box. Large banks may make exceptions for high-balance depositors, so the relationship matters more than the product menu.

Expect that a portfolio loan can carry terms a QM loan cannot, such as interest-only or balloon structures, and that it may price higher than a conforming loan. A portfolio lender also keeps servicing and decisions in one place, while a sold loan may move to a new servicer. Neither outcome is automatically better.

Key Terms Defined

Bank statement loan: a mortgage where income is estimated from averaged bank deposits instead of traditional personal-income documentation.

Portfolio loan: a loan the lender makes and keeps on its own books.

Non-QM: a mortgage that falls outside the qualified-mortgage standard.

Securitization: pooling loans and selling interests in the pool to investors.

Expense factor: the percentage a lender subtracts from business deposits to estimate net income.

Tax treatment varies; consult a qualified professional before relying on any deduction.
