How to Qualify for a 24-Month Bank Statement Loan on a Single-Family Property

The Quick Read: You qualify when two years of consecutive bank statements show steady, well-documented deposits that, after the lender’s expense treatment, cover your total monthly debts with room to spare. The lender averages your deposits across all 24 months, strips out anything that isn’t real income, and tests the result against your debts and the new housing payment. Credit, reserves, leverage and the property still matter, and every file is underwritten individually.

• Qualifying income comes from the deposit average, not your tax return, so heavy write-offs matter less.
• Business statements get an expense factor set by the lender. Personal statements usually skip it.
• Transfers, gifts, refunds and loan proceeds come out of the deposit total before averaging.
• Reserves commonly run around 6 months of the housing payment.
• Occupancy decides the paperwork regime: owner-occupied is a consumer mortgage, while a rental is business-purpose.

This guide walks through what the loan is, how underwriters treat your statements step by step, where the rules bend, and how to decide whether this is the right tool. For the full picture of alternative-documentation and investor products, see Lendmire’s complete DSCR loans guide.

What Is a 24-Month Bank Statement Loan?

A 24-month bank statement loan is a non-QM mortgage that proves income with two years of deposits instead of traditional personal-income documentation. Non-QM means the loan falls outside the standard “qualified mortgage” box that agency-style underwriting uses. It is still a fully underwritten loan. The borrower is reviewed on documented income under the applicable program, subject to lender guidelines.

It fits self-employed borrowers whose traditional personal-income documentation understates what the business really brings in. Think of a contractor, a consultant, a restaurant owner or a 1099 sales professional. Deductions shrink taxable income. Deposits tell a truer story.

Trade press describes the typical setup the same way. Scotsman Guide notes that self-employed borrowers can supply 12 to 24 months of personal or business statements. It adds that non-QM lenders still must confirm the borrower can repay, but have more flexibility in how they do it.

Across Lendmire’s wholesale network, the standard documentation is bank statements, business or personal, with income built from deposit averages and lender-specific expense factors. The 24-month version simply uses the longer window. Lendmire’s 12-month bank statement loan guide covers the shorter option.

Why Choose 24 Months Over 12?

Choose 24 months when your income swings, when your best months are old, or when a single strong year would otherwise flatter the average. Choose 12 when your recent year is clearly stronger and growing. Neither is better in the abstract.

Be honest about which way your trend runs. A longer average rewards stability and punishes fast growth. Many borrowers assume more history always helps. It doesn’t. If last year was your breakout year, the older months will pull qualifying income down.

Some lenders in the network will offer a choice of window. Others set the window by program. Which one applies depends on the program sheet for your file.

How Underwriting Turns 24 Months of Deposits Into Income

Underwriting follows a repeatable sequence: collect statements, screen the deposits, apply expense treatment, average, then test against your debts. The steps are consistent across programs. The percentages are not, because each lender sets its own.

1. Gather 24 consecutive months. Every page of every month, no gaps. A missing page invites questions.

2. Pick the account type. Business statements get an expense factor. Personal statements generally don’t, because you already paid expenses before the money landed.

3. Screen the deposits. Inter-account transfers, owner draws put back in, refunds, gifts, cash infusions and loan proceeds come out. Large unexplained deposits typically need sourcing.

4. Apply the expense factor. On business statements, the lender applies a factor to reflect the cost of running the business. Scotsman Guide gives 50% as an example of a flat factor, and it describes a P&L or an expense statement from a third-party tax professional as alternatives. Treat 50% as a market illustration, not a promise. The lender sets the factor, not you.

5. Apply ownership percentage. If you own part of the business, only your share counts.

6. Average across all 24 months. The total of eligible deposits, after expense treatment, divided by 24 gives monthly qualifying income.

7. Run debt-to-income. Debt-to-income (DTI) compares your total monthly debts, including the new housing payment, against that income. Scotsman Guide reports some non-QM lenders go to a 50% DTI where government-sponsored programs commonly cap near 43%. Those are market-wide figures, so your file’s limit depends on the program.

8. Review credit, reserves, leverage and the property.

Here is the logic with round, hypothetical numbers shown as ratios rather than dollars. Say your business deposits total twice what your clean personal-account deposits would. A 50% expense factor on the business account brings it down to the same level as the personal figure. The lender then lands on the same qualifying income either way. That is why choosing the right account to submit matters. It is also why a CPA-prepared expense statement can move the result when the default factor overstates your costs.

Business Statements vs. Personal Statements

Business statements carry an expense factor, while personal statements generally don’t. Which one fits depends on how your money actually flows. Commingling the two muddies both.

Pick the cleaner account. If your deposits already flow into one clearly labeled account, say so up front and give the loan officer the statements that tell the simplest story. Underwriters hunt for a clear pattern of business income.

Why Single-Family Is the Base Case

Single-family is the cleanest property type for this loan because it is the simplest to appraise and the easiest to place across lenders. Condos, 2-4 unit properties and unusual homes can add overlays. A standard single-family home rarely does.

The property side of the file runs on an appraisal, a purchase contract and the usual title work. The bank statements prove you. The appraisal proves the house.

Occupancy is where the file changes shape. On a primary residence, select lenders in the network go up to 90% LTV on a purchase or rate-term refinance. LTV, or loan-to-value, is the loan amount as a share of the property’s value. On owner-occupied cash-out, the ceiling is up to 80% LTV with a fixed expense ratio, and 75% when an accountant prepares the ratio. Loan amounts run from roughly $125,000 to $3,500,000. Those are typical ranges, subject to lender guidelines, loan size and credit.

Investment property works differently. On an investment cash-out, leverage tops out around 75% LTV. Leverage on an investment purchase using bank statements varies by lender, so it doesn’t pay to assume a number. If the property is a pure rental, a loan that is reviewed on the property’s rent is often the more natural tool.

Occupancy also decides the disclosure rules. An owner-occupied bank statement loan is a consumer mortgage, so consumer disclosure rules apply. A non-owner-occupied rental is generally business-purpose and treated differently. Under Regulation Z’s business-purpose exemption, credit extended primarily for a business purpose is exempt from the consumer rules. The loan’s purpose matters, not just the property label. A cash-out on a rental used for personal spending can still be consumer-purpose.

Key Terms Defined

Non-QM: a mortgage that falls outside the standard qualified-mortgage definition but is still underwritten for ability to repay.

Expense factor: the share of business deposits the lender treats as operating costs rather than income.

DTI (debt-to-income): your total monthly debts divided by your qualifying monthly income.

Reserves: liquid savings left after closing, commonly around 6 months of the housing payment on these loans.

LTV (loan-to-value): the loan balance as a percentage of the property’s value.

Asset depletion: qualifying from liquid assets instead of deposits. On a primary residence it runs up to about 80% LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Statement Red Flags to Fix Before You Apply

Most failed files stumble on messy statements, not weak income. The common culprits are fixable if you catch them early.

• Large unexplained deposits. Document the source before the lender asks.
• Transfers between your own accounts. These get stripped, so label them.
• Commingled personal and business funds. Separate them months before applying if you can.
• Declining deposits. Underwriters may weigh the recent months more heavily. Be ready to explain a dip.
• Overdrafts and missing pages. Both raise questions. Send complete statements.
• Pass-through money. A contractor’s subcontractor payments may need exclusion or a higher effective factor.

If you can’t produce a CPA letter or profit-and-loss statement to justify a lower expense ratio, the file reverts to the lender’s default. Assume the default until you prove otherwise.

Businesses under 24 months old are a harder case. Some programs weigh strong liquid assets and credit alongside a shorter history, but that depends entirely on the program. Don’t count on it.

Documents to Gather

Gather these before you apply:

• 24 months of complete, consecutive bank statements for the account you’ll use
• A CPA or tax-professional letter or profit-and-loss statement, if you want to support a lower expense ratio
• Proof of business ownership and your ownership percentage
• Business license or registration, where applicable
• Recent statements for savings and investment accounts that will show reserves
• Government ID and authorization for a credit review
• The purchase contract and property details

Step-by-Step Process

1. Pull 24 months of statements and read them as an underwriter would. 2. Flag and document transfers, large one-time deposits and gaps. 3. Decide which account tells the cleanest story. 4. Talk with a broker who can compare programs, since expense factors and overlays differ by lender. 5. Line up reserves. Around 6 months of the housing payment is common. 6. Apply, then respond to underwriting questions fast and completely. 7. Complete the appraisal and property review.

Start preparing at least a few months before you make offers. The longer your statements stay clean, the better the file reads.

Are You Ready? A Quick Self-Check

• Do my last 24 months of deposits look steady or growing, with no sharp decline?
• Can I explain every large deposit in a sentence?
• Do my business and personal funds stay separate?
• Do I have meaningful reserves?
• Is the home a standard single-family property?

Mostly yes: you are likely ready to talk to a broker. A few no answers: fix first, then apply. Mostly no: consider another path.

Other Paths If This Doesn’t Fit

If your deposits are thin or lumpy, a longer window may work better. If you buy the home as a pure rental, a loan that is reviewed on the property’s rent may fit better, since it skips personal income testing. Where the property will be your home, other documentation types, like a P&L-based approach, may suit you. 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.
