Requirements For A 24-month Bank Statement Loan

Requirements For A 24-Month Bank Statement Loan — The Quick Read: A 24-month bank statement loan is reviewed a borrower off two years of personal or business deposit history instead of traditional personal-income documentation, letting a lender average deposits into a monthly income figure. Underwriters apply an expense factor to business-account deposits, then run that income through a normal debt-to-income or residual-income check. Twelve months and twenty-four months are both legitimate look-back windows — which one helps depends on whether income is rising, flat, or seasonal, not on which period sounds more thorough.

Here’s what matters most before diving into the mechanics:

• A 24-month bank statement loan is a documentation method, not a loan type with its own rate sheet — it’s a way of proving income for self-employed and 1099 borrowers.
• Statements can come from personal accounts, business accounts, or both, and the two are treated differently in the math.
• No single expense-factor percentage applies across every lender — it varies by program and can be adjusted with CPA documentation of actual costs.
• Twenty-four months isn’t automatically “safer” than twelve. The window that produces a better file depends entirely on the shape of the deposit history.
• For a real estate investor buying rental property specifically, a DSCR loan — one that is reviewed on the property’s rent instead of the owner’s income — is often the more direct path, and it’s worth understanding both before choosing one.

What a 24-Month Bank Statement Loan Actually Is

A 24-month bank statement loan lets a self-employed borrower prove income with two years of deposit history instead of two years of traditional personal-income documentation. The lender totals the deposits, divides by the number of months, and treats that average as qualifying income for the loan application.

This exists because traditional personal-income documentation often understate what a self-employed person actually earns. Legitimate deductions, depreciation, and business write-offs shrink the net income line on a Schedule C — the same line a conventional lender uses to calculate debt-to-income. A borrower can be cash-flow healthy and still look thin on paper. Bank statement underwriting sidesteps that gap by looking at what actually moved through the accounts.

It isn’t a stated-income or no-documentation product, even though it gets called that informally. What’s different is the evidentiary source — deposit history rather than a filed tax return — not the presence of documentation itself.

For a deeper walkthrough of the full application process, Lendmire’s complete guide to 24-month bank statement loans covers the documentation timeline in more detail.

Key Terms Defined

Bank statement loan — a mortgage that qualifies a borrower’s income using deposit history from bank accounts instead of traditional income documentation.

Non-QM loan — a mortgage that falls outside the government’s “qualified mortgage” underwriting box, giving lenders more flexibility on how they document and evaluate income.

Debt-to-income ratio (DTI) — the borrower’s total monthly debt payments divided by gross monthly income, used to judge whether a new payment fits their budget.

Expense factor — a percentage subtracted from business-account deposits to account for the fact that a business account holds operating costs mixed in with revenue, not pure income.

DSCR (debt-service coverage ratio) — a ratio that compares a rental property’s monthly income to its monthly mortgage payment (PITIA — principal, interest, taxes, insurance, and any HOA dues), used to qualify investment-property loans on the property’s cash flow instead of the borrower’s income.

Core Eligibility Snapshot

Bank statement guidelines vary meaningfully by lender, so treat the table below as typical shape, not a universal rulebook.

Recent non-QM production data gives a useful reality check on who actually uses these products: the average non-QM borrower carried a 776 FICO score and closed near 75% loan-to-value, according to Scotsman Guide — numbers that look almost identical to conventional conforming borrowers, not a distressed-credit segment. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

The Document Checklist

Every 24-month bank statement file, regardless of lender, tends to need the same core stack of paperwork. The lender still needs verified deposit history, proof of business ownership, and enough consistency in the numbers to support a reasonable ability-to-repay conclusion.

Missing pages, closed accounts mid-period, or a name mismatch between the borrower and the account are the most common reasons a bank statement file stalls. Gathering statements as one continuous, unbroken 24-month set before applying avoids most of that friction.

How Underwriters Turn Deposits Into Qualifying Income

The math itself is simple in concept, layered in practice. The lender adds up total deposits over the chosen window, strips out anything that isn’t income — transfers between the borrower’s own accounts, loan proceeds, one-time gifts — and divides what’s left by the number of months in the period.

Personal-account statements are usually treated as closer to take-home income already, since a personal account isn’t presumed to carry business operating costs. Business-account statements get an additional step: an expense factor reduces gross deposits down to an estimated net income figure, because a business account commingles revenue with payroll, rent, supplies, and every other operating cost.

There’s no fixed expense-factor percentage that applies across the industry — it differs by lender and program, and a borrower whose actual costs run lower than the default assumption can often override it with CPA-documented expense ratios. That flexibility is one of the more underused levers in a bank statement file; borrowers rarely ask about it, and lenders rarely volunteer it.

Whatever qualifying income comes out of that calculation feeds into a standard debt-to-income or residual-income review — the same underwriting question every mortgage ultimately asks: does this borrower’s income reasonably support this payment.

When 24 Months Beats 12 (And When It Doesn’t)

Neither window is objectively stronger. The one that helps depends on the shape of the borrower’s actual deposit history — a rising business favors the shorter window, a recovering or seasonal one often favors the longer one.

A borrower whose last twelve months clearly outperform the prior year almost always wants the shorter window run first — 24 months would just dilute a strong recent trend with weaker older numbers. The reverse is true for a borrower coming off a slow stretch who’s since recovered: a longer average smooths a rough patch that a 12-month snapshot would expose in isolation. For a side-by-side on the shorter program specifically, Lendmire’s requirements for a 12-month bank statement loan breaks down that comparison directly, and its companion piece on reserve requirements for a 12-month bank statement loan covers the liquidity side of that same decision. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Special Scenarios That Change the Math

Under two years of self-employment. Most programs want to see roughly two years of business ownership. A borrower with less than that isn’t automatically shut out, but the file usually needs stronger compensating factors — solid credit, larger reserves, or a related prior work history in the same field.

Recent bankruptcy or foreclosure recovery. A 24-month window naturally captures more of a recovery period than a 12-month snapshot, which is exactly why some lenders prefer or require it for borrowers coming off a credit event — the longer track record does more of the persuading.

Multiple income streams or multiple businesses. Reconciling deposits across several accounts, or across a business that changed structure mid-period, takes longer and invites more underwriter questions. This is where a two-year lookback gets genuinely harder to manage than a one-year one — more accounts, more months, more chances for an unexplained deposit to need a paper trail.

Declining recent months. If the most recent months trend down from the earlier ones, a 24-month average can actually work against the borrower by including stronger months in the mix without reflecting where the business stands now — sometimes the honest answer is that a shorter window, or a different documentation path entirely, fits better.

Credit tier matters as much as the documentation method itself. Recent non-QM performance data shows impairment rates for borrowers with scores below 660 approaching 20%, and borrowers under 700 accounting for the large majority of the recent rise in impairments, according to Scotsman Guide. The statement window doesn’t neutralize credit risk — it’s a documentation choice layered on top of, not a substitute for, the credit picture underneath.

Where This Fits for Real Estate Investors

Most investors buying rental property don’t actually want to document their own income at all — that’s the whole appeal of qualifying on the property instead. A 24-month bank statement loan is still a personal-income product; the deposits belong to the borrower, and the payment gets sized against the borrower’s own cash flow, not the rent the property produces.

DSCR loans are built for a different question entirely: does the rent cover the payment. DSCR loans are designed for non-owner-occupied investment properties, and because they’re business-purpose loans, they’re reviewed differently than a standard owner-occupied mortgage. A borrower qualifies primarily on property-level rental income covering the payment, subject to lender guidelines — no personal bank statements, no expense-factor math, no averaging deposits across two years.

Across select lenders in Lendmire’s wholesale network, purchase leverage on DSCR files typically lands around 75%-80% loan-to-value, with a handful of higher-leverage programs reaching 85% for borrowers around a 700 credit score. Cash-out refinances generally top out closer to 75% LTV, with roughly six months of ownership seasoning expected on most files. Coverage ratios starting near 1.00 — meaning rent roughly matches the monthly payment — are a floor on select programs, never a universal standard, and stronger coverage tends to open better leverage. Reserve expectations commonly run around six months of PITIA, stepping up toward nine months on larger loan amounts above roughly $1.5 million, and standard loan sizes on these programs generally run up to $3 million.

Credit floors run as low as 620 on parts of the network, though most programs prefer something closer to 660, and 700-plus is typically what unlocks the top leverage tiers. None of that changes based on how much a borrower puts down — a bigger down payment lowers the payment and can lift the coverage ratio, but it doesn’t override a credit floor, a reserve requirement, or a leverage cap. The strongest files clear both tests at once: enough equity in the deal and enough rent to cover the payment.

An investor whose rental property doesn’t quite cash-flow enough for a straight DSCR approval, but who has clean personal or business deposit history, may genuinely be better served by a bank statement approach on that specific purchase — the two products solve different documentation problems, and choosing between them is a real decision, not a hierarchy. Lendmire’s comparison of DSCR loans versus bank statement loans for investors walks through that decision in more depth, and the complete DSCR loans guide covers how the property-income qualification process works end to end.
