How to Qualify on Bank Statements After a Down Year

The Quick Read: It depends on the trend in your deposits, not just the average, and a down year does not disqualify a file by itself. Underwriters still read the direction of income, so a dip needs a documented cause and evidence that it has stopped. A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines.

• Income comes from 12 months of business or personal statements, averaged, with an expense factor on business accounts.
• A recent decline can bring an explanation request, a more conservative average, or an ineligible finding.
• A one-off event (a lost client, an illness, a delayed project) reads differently from a structural decline.
• Clean deposits matter more in a down year: no unexplained lumps, no shuffling between accounts.
• If the property is a rental, a DSCR loan may avoid the income question entirely.

How Deposits Become Qualifying Income

The mechanics are simple. The lender takes a window of statements, screens out deposits that are not income, averages what is left, and applies an expense factor if the account is a business account. That number feeds the rest of the file.

Across the wholesale network, the standard documentation is 12 months of business or personal statements. Some programs allow a 24-month window, and HousingWire’s non-QM guide describes the same 12-to-24-month range along with an expense factor that may apply.

Here is the sequence an underwriter follows:

1. Pick the window. Twelve months is the common baseline. Which window applies depends on the program and sometimes on the underwriter.

2. Screen the deposits. Transfers between your own accounts, loan proceeds, tax refunds, gifts and asset-sale proceeds come out. They are not recurring income.

3. Average the remainder across the months in the window.

4. Apply the expense factor on business accounts. Personal-account deposits generally count closer to face value. Business deposits are discounted for overhead. Lenders set the factor differently, so no universal formula exists, and a few programs accept an accountant-prepared ratio.

5. Run the rest of the file. Credit, debt-to-income, LTV, reserves and property eligibility all still apply. Reserves commonly run around 6 months of the housing payment, subject to lender guidelines.

A larger deposit total helps the income line. It does not fix weak credit, thin reserves, or a property the lender will not take.

What a Down Year Looks Like to an Underwriter

An underwriter reads a trend, not a single number. Monthly totals get compared, seasonality gets checked, and a decline gets flagged.

When the most recent months run below the average, the file can go one of several ways. The underwriter may ask for a written explanation. They may use a lower, more recent figure instead of the full-window average. They may ask for more documents. Under some program matrices, a steep recent drop makes the file ineligible until income stabilizes.

Seasonal dips that repeat in prior years are treated differently from a new decline. A landscaper with slow winters every year has a pattern. A contractor whose deposits fell for five straight months has a question to answer.

The cause matters as much as the size. Underwriters separate three stories:

• One-time event. A major client left, a project slipped, or the owner was out sick. Recovery evidence carries the file.
• Seasonal pattern. The prior year shows the same shape. Little adjustment is usually needed.
• Structural decline. The market shrank or the business model changed. This is the hardest story to document past.

The no-tax-return label leads some borrowers to think the drop gets ignored. It does not. Bank statements change the documentation method. They do not change the question of whether the borrower can repay, and the lender still has to reach a reasonable conclusion that the loan is affordable.

12 Months or 24: Which Window Fits a Down Year?

A 24-month window can soften a down year by blending a strong prior year with a weak recent one. A 12-month window penalizes a taper because the weak months carry more weight. Neither window hides direction, since underwriters read the monthly pattern inside both.

Most programs in the network start from 12 months, so the practical choice often comes down to whether the program offers 24 and whether the underwriter will accept it. Ask early. Do not assume. Lendmire’s piece How to Choose 12 vs 24 Months of Bank Statements After a Down Year goes deeper on that choice.

A Worked Down-Year Example

Run this as a modeled illustration, not a quote. Picture a self-employed borrower with a business account. Over 12 months, the first eight months of deposits run strong and the last four drop noticeably, after one large client left.

The underwriter screens out a transfer from the borrower’s savings and a one-time asset sale. The remaining deposits get averaged across 12 months. The expense factor then discounts the average because it is a business account. The result is the qualifying income.

Now the underwriter looks at slope. The last four months sit below the average. Three outcomes are possible. The underwriter accepts the 12-month average with a letter explaining the lost client. Or the underwriter uses only the lower recent months, which shrinks income and may tighten the debt-to-income ratio. Or, if the decline has not stopped, the file waits.

A 24-month window on this same borrower would pull in a stronger prior year and raise the average. The most recent months still get read, though, and the underwriter may shorten the window to capture the lower trend. The window helps the arithmetic. It does not erase the trend.

Prove the Recovery

When a file shows a dip, the borrower’s job is to document the cause and show the bottom is behind them. These documents carry that argument:

The year-to-date P&L should match the deposits on the statements. Numbers that disagree create more questions than they answer. A letter that names a specific event, with a date, reads better than a general statement that business was slow.

Clean Up Deposits Before You Apply

A down year puts every deposit under a brighter light. Underwriters examine sources, patterns, frequency, account ownership, transfers and unusual activity, and they may ask for invoices, contracts or proof of ownership.

Do:

• Keep business and personal funds in separate accounts when you can.
• Keep source documents for any large deposit.
• Leave the account history alone for the months in the window.

Don’t:

• Move money between your own accounts without a reason you can document.
• Deposit a lump sum to lift the average. Averaging dilutes one check, and a lump gets sourced and usually excluded.
• Run overdrafts. Repeated overdrafts and returned items are common red flags in deposit-based underwriting.
• Count pass-through money, such as client funds that go straight out to subcontractors, as your income. It may be trimmed or excluded.

Multi-owner businesses add one more point: only your ownership share counts, and ownership documents are usually required.

Leverage and Loan Parameters

Program numbers vary by lender, so treat these as typical ranges from select lenders in Lendmire’s wholesale network, subject to lender guidelines and credit approval.

On a primary residence purchase or rate-term refinance, bank statement programs reach up to 90% LTV, and the strongest files earn the top of that range. An asset-depletion alternative, which qualifies from liquid assets, runs to about 80% LTV on a primary residence. On an owner-occupied cash-out (primary residence or second home), leverage tops out at 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio, depending on loan size and credit. On an investment-property cash-out, expect roughly 75% LTV. Investment purchase leverage on bank statement documentation varies by lender.

Loan sizes run roughly $125,000 to $3,500,000. The structure also depends on occupancy. An owner-occupied file is a consumer mortgage. A non-owner-occupied rental, including a short-term rental, is a business-purpose loan. Which one applies is set by how you will use the property.

For the federal frame behind consumer deposit-based income, the CFPB’s ability-to-repay compliance guide says income does not have to be salaried or full-time to count, but the creditor must make a reasonable, good-faith repayment determination. That is why a decline gets read even when no tax return is involved.

Where Bank Statements Can’t Help

Bank statements are not the answer to every down year. Skip this route when:

• The decline is ongoing and unexplained. No window fixes a slope that keeps dropping.
• Debt-to-income is the real limit. Bank statement income feeds personal DTI. An investor with many financed properties can run out of DTI room even when deposits look healthy.
• The tax-return route works fine. If your returns already show strong income, you may not need the alternative.
• The problem is credit or property, not income. Deposits do not repair either.

For a rental purchase, the cleaner path is often a DSCR loan. DSCR tests whether the property’s rent covers its payment, not the borrower’s deposits. HousingWire’s non-QM guide lists bank statement loans and DSCR loans as separate tools in the same toolbox. One tests the borrower’s income. The other tests the property.

An investor-forum thread on BiggerPockets carries a reply that declining deposits can be a red flag and suggests going DSCR instead. That is sentiment, not a rule, but it matches what happens in files: a rental that rents well sidesteps the down-year question. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Programs below 1.00 coverage are available through select lenders in the network, with LTV and terms adjusted. Lendmire’s complete DSCR loans guide walks through how that test works.

Here is the decision in practice. If the property rents well, run DSCR first. If the rent is thin, or the purchase is an owner-occupied home or second home, bank statements may be the only deposit-based route. Run both calculations before choosing.

Pre-Application Checklist

1. Pull 12 months of full statements, every page, every account you plan to use.

2. Mark every non-income deposit and gather the source documents.

3. Write the explanation letter naming the cause of the dip and its date.

4. Prepare a year-to-date P&L that ties to the recent statements.

5. Ask whether a tax professional letter can support a lower expense factor.

6. Check reserves and credit before you apply. Strong reserves and credit can offset a weaker trend, subject to lender guidelines.

7. Consider timing. If income is turning up, a month or two of stronger deposits can change how the window reads.

Key Terms Defined

Expense factor: the percentage of business deposits a lender discounts to account for overhead before counting the rest as income.

Qualifying income: the monthly income figure a lender uses after screening and averaging deposits.

Non-QM: a loan that does not meet standard qualified-mortgage rules, which describes the documentation method rather than the borrower’s credit.

Asset depletion: a method that qualifies a borrower from liquid assets instead of deposits or traditional personal-income documentation.

DSCR: debt service coverage ratio, which compares a property’s rent to its full monthly housing obligation.

If you are self-employed and want to see how the numbers work, Lendmire can help you compare bank statement loan options based on your deposits, the property, credit profile, leverage, and your goals. Consumer mortgage licensing for this lane covers 16 states, and every file is underwritten individually by the lender; this is not a commitment to lend.

Tax treatment varies, so consult a qualified professional.
