Process And Timeline For A 24-month Bank Statement Loan

Process And Timeline For A 24-month Bank Statement Loan — The Quick Read: A 24-month bank statement loan moves through five stages. First, the borrower gathers documents. Then the lender reviews deposits and applies an expense factor. Next comes the income-to-DTI conversion. After that, underwriters check credit and reserves. Finally, the file goes through appraisal and closes. There’s no fixed calendar for any of this. How long a file takes depends on how complete the statements are on day one, whether deposits need explaining, and how the lender treats the entity’s income. Real estate investors have a more common option, though. Most skip this personal-income process entirely. Instead, they qualify using the property’s own rental income.

What a 24-Month Bank Statement Loan Actually Is

A 24-month bank statement loan is a non-QM mortgage product. Non-QM means it doesn’t meet the standard rules for a “qualified mortgage,” so the lender uses a different method to check repayment ability. This product works for self-employed borrowers who don’t have clean traditional employment income to show. Instead of standard personal-income paperwork, the lender reviews 24 consecutive months of personal or business bank statements. Then it builds a qualifying income figure directly from deposit activity.

That’s the whole pitch: the lender reviews rental income or deposit activity instead of personal-income documentation, and calculates income from what actually landed in the account. It sounds simple. But the mechanics underneath it are not.

Loan-level due diligence filed on securitized non-QM pools shows how this works in practice — and it’s more structured than most marketing pages suggest. One securitization’s own guideline language treated a “12-month bank statement program” as its own named product, with a specific rule for whether a profit-and-loss statement or bank statements alone were acceptable. This confirms that 12-month and 24-month aren’t a single sliding scale. They’re two separate underwriting paths, each with its own documentation rules. That distinction matters more than most borrowers realize. It’s worth understanding before you assume “more months” automatically means “easier approval.” For a side-by-side look at how the shorter version handles the same review, see the process and timeline for a 12-month bank statement loan.

Key Terms Defined

Bank statement loan — a non-QM mortgage that calculates income from bank deposits over 12 or 24 months instead of traditional personal-income documentation or W-2s.

Expense factor — the percentage of business deposits an underwriter treats as overhead before counting the rest as income. It commonly defaults to 50% unless a CPA documents a lower figure.

DTI (debt-to-income) — the ratio of a borrower’s monthly debt obligations to their qualifying monthly income. Lenders use it to size how much loan a borrower can support.

Large deposit — an unusually big or unexplained deposit that underwriters review separately. It’s generally flagged once it crosses a threshold tied to a share of qualifying income.

Non-QM — any mortgage that doesn’t meet the standard documentation safe harbor for a “qualified mortgage.” This means the lender uses an alternative method to determine repayment ability.

DSCR (debt-service coverage ratio) — a ratio comparing a rental property’s monthly rent to its monthly PITIA (principal, interest, taxes, insurance, and association dues). Lenders use it in place of personal income on investment-property loans.

PITIA — the full monthly housing obligation: principal, interest, taxes, insurance, and any association dues. It does not include maintenance, vacancy, or capital expenses.

The Process, Stage by Stage

The sequence stays consistent across the non-QM bank statement space. But the specific numbers behind each stage vary by program.

Stage 1: Document Collection

The borrower submits 24 consecutive months of statements — personal, business, or both, depending on how income is earned. This is the single biggest lever a borrower controls. A complete, organized statement package with no gaps moves through underwriting with far fewer follow-up requests. A file missing pages or showing account-number mismatches slows things down.

Stage 2: Deposit Aggregation and the Expense Factor

Underwriters total every eligible deposit across the 24 months. Then they strip out anything that isn’t real income — internal transfers between the borrower’s own accounts, loan proceeds, one-time asset sales. What’s left gets averaged into a monthly figure.

For business accounts, that average isn’t the qualifying income figure yet. A business has overhead, so the lender applies an expense factor first. Loan-level due diligence on actual securitized files shows a flat 50% expense ratio as the industry default for many service businesses. That means roughly half of every dollar deposited counts as cost of doing business before the rest counts toward income. That default can move — but only downward, and only with third-party support. A CPA, enrolled agent, or tax preparer can submit a letter documenting the business’s actual expense ratio based on filed returns. Underwriters will accept a lower figure if they can verify it against the bank activity and the type of business. It is not a rubber stamp. Guideline documentation from one securitized program said an alternate ratio is acceptable only when the underwriter can confirm it’s accurate from the statements themselves or from the nature of the business.

Stage 3: Income-to-DTI Conversion

Once the lender applies the expense factor, the resulting monthly figure becomes the borrower’s qualifying income. It plays the same role W-2 or 1040 income plays in a conventional file. This step is where small assumption errors turn into real outcomes. One documented due-diligence finding showed a loan miscalculated with a 40% expense ratio instead of the required 50%. Once corrected, the borrower’s DTI rose above the program’s maximum. A 10-point difference in expense assumption was the gap between an approvable file and a declined one.

Stage 4: Large-Deposit Review

Underwriters separate out unusually large or unexplained deposits from the ordinary income calculation. Actual due-diligence exception files define this threshold as roughly half of qualifying income, or a set dollar figure, depending on which framework the program uses. Sometimes a deposit can’t be tied to normal business revenue — a single large client payment, an asset sale, a one-time transfer. When that happens, the resolution isn’t always a decline. In documented cases, the lender simply excludes the deposit from the income math, and the deal moves forward on the remaining, verifiable deposits.

Stage 5: Credit, Reserves, and the Rest of the File

Once the lender locks in qualifying income, the loan goes through the same credit, DTI, loan-to-value, and reserve review any other non-QM file goes through — appraisal, title, conditions, and closing. The documentation path differs from a conventional loan. But the underwriting rigor doesn’t. For the specific reserve and file-completeness expectations tied to the 24-month version of this program, see reserve requirements for a 24-month bank statement loan and requirements for a 24-month bank statement loan. Every figure here varies by lender and program. Guidelines, property type, leverage, and credit profile all play a role.

12-Month vs. 24-Month: Two Different Products, Not One Sliding Scale

Choosing between a 12-month and 24-month review isn’t about which one is “easier.” It’s about which rule set fits the borrower’s actual income pattern. A longer look-back can smooth out a seasonal or lumpy business. That helps a borrower whose income swings quarter to quarter. But it also means gathering twice the statement volume, and facing twice the exposure to large-deposit and expense-ratio scrutiny along the way. A shorter 12-month window means less paperwork, but a smaller sample size. That can mean closer scrutiny of consistency across those statements, since there’s less data to smooth out an unusual month.

Neither term is categorically better. The right one depends on which program’s specific rules — P&L acceptance, expense-ratio floor, large-deposit threshold — best match the file in front of the underwriter.

Where the Process Gets Complicated

A few edge cases show up often enough in actual loan-level review. They’re worth knowing before a borrower assumes the process is purely mechanical.

The expense-ratio floor cuts both ways. A CPA letter can lower the ratio below the program default. But many guidelines also cap how low that CPA-stated ratio is allowed to go. “Get a CPA letter” isn’t an automatic path to the highest possible qualifying income. It’s bounded by lender policy.

Miscalculated expense ratios show up again and again in third-party file audits. This isn’t a rare mistake. The 40%-versus-50% example above shows how a single assumption made at initial underwriting — not just at final review — can determine whether a deal survives due diligence intact.

Federal oversight applies even without agency documentation. Non-QM loans still fall under the Ability-to-Repay framework in Regulation Z. This rule requires lenders to make a reasonable, good-faith determination that a borrower can repay a home loan. It doesn’t dictate exactly how much income is needed for a given debt level. Instead, it requires that whatever method a lender uses be reasonable and applied consistently. That’s precisely why the expense-factor math above exists as a documented, defensible process rather than lender discretion alone.

Self-employment isn’t a shrinking pool of borrowers, either. Full-time self-employment in the U.S. reached a record 16.77 million in the most recent year tracked, up from 16.74 million the year before. Growth in incorporated self-employment drove much of that increase, according to the SBE Council. That’s the same population structuring income through pass-through entities, taking legitimate depreciation and expense deductions, and showing tax-return net income well below actual cash flow. This is the exact borrower profile bank statement underwriting exists to serve.

Why Rental Property Investors Often Route Around This Process

Here’s the disconnect worth naming directly. Bank statement loans solve a personal-income documentation problem. But most real estate investors buying a rental property don’t need their personal income documented at all. They need the property’s rent to cover its own payment.

DSCR loans are built for non-owner-occupied investment properties. Because they’re business-purpose loans rather than consumer mortgages, lenders review them differently than a standard owner-occupied loan. As business-purpose files, they’re exempt from the disclosure and re-disclosure steps required on consumer mortgages. Qualification runs primarily on the property’s own rental income covering the payment, subject to lender guidelines. There are no bank statements, no expense factors, and no personal DTI conversion at all.

Across the wholesale network Lendmire (NMLS# 2371349) works with, most DSCR purchase files land at 75%-80% loan-to-value. Select high-leverage programs can reach 85% for borrowers around a 700 credit score. Cash-out refinances typically top out closer to 75% LTV, with roughly six months of ownership seasoning expected on most files. A 1.00 coverage ratio — rent divided by the full monthly PITIA — is where some select programs start. It’s not a universal floor. Stronger coverage generally opens better leverage. Coverage below 1.00 is still available through select lenders in the network, though leverage and terms adjust accordingly. Credit floors run as low as 620 in parts of the network, though most programs prefer something closer to 660. A 700+ score tends to unlock the strongest leverage tiers. Loan amounts on standard programs run up to $3,000,000. Reserve expectations commonly sit around six months of PITIA, stepping up toward nine months on larger loan amounts, and sometimes waived entirely on conservative, lower-leverage rate-and-term files.

Here’s something worth being direct about. Clearing 1.00 coverage is not the same thing as positive cash flow. DSCR only measures rent against PITIA. Repairs, vacancy, property management, utilities, and capital expenses sit entirely outside that ratio. A file can clear 1.00 or better and still need real reserves for the costs the ratio doesn’t count.

Consider an investor with two or three rental properties, filing traditional personal-income documentation that shows modest net income after depreciation. That investor is often a stronger DSCR file than a bank statement file. Why? Because the lender is actually underwriting the property’s rent, not the owner’s personal tax picture. Investor purchase activity backs this up at scale. Investors purchased roughly 85,000 homes per month in the first half of the most recent tracked period, up slightly from 84,000 a year earlier. More than 85% of home investors own fewer than five properties — meaning most of this market is small-scale, individually financed operators, according to Scotsman Guide. That same reporting flagged that serious delinquencies in this space rose from roughly 0.5% to around 2% over a recent multi-year stretch. That’s a reminder: underwriting quality on the documentation side — whether bank statement expense factors or DSCR reserve cushions — feeds directly into how these loans perform down the line.

Bank statement loans aren’t a fringe product, either. They made up roughly 36% of non-QM lock volume in a recent month, ahead of investor/DSCR loans at just over 32%, per Scotsman Guide’s tracking of the space. The two products serve overlapping but distinct purposes. One documents a person’s income. The other documents a property’s income. For a direct comparison of when each makes sense, see DSCR loan vs. bank statement loan for investors.

On the appraisal side, agency rental-income documentation uses standardized forms — Fannie Mae’s Form 1007 comparable rent schedule for one-unit properties, and Form 1025 for two-to-four-unit properties. Those form names carry over into non-agency appraisal ordering conventions, even though DSCR loans never touch Fannie or Freddie eligibility.

What Investors Should Do Before Applying

The pre-application work matters more than anything that happens after the file is submitted. For a bank statement route, gather the full statement set before applying. Avoid transfers between accounts that muddy the deposit trail. Line up a CPA letter in advance if the expense ratio needs to move below the program default. For a rental-property purchase or refinance, run the numbers on rent-to-payment coverage before shopping properties. A deal that clears strong coverage opens more leverage options than one that barely clears the floor.

If you’re weighing a rental purchase or refinance and want to see how the numbers actually stack up, Lendmire can help compare DSCR loan options based on the property’s rental income, credit profile, available leverage, and overall investor goals.
