Explain A Declining Income Year — The Quick Read: A declining income year on a bank statement loan is a documentation problem, not an automatic denial. Underwriters compare recent deposits against your longer trend, and a soft year usually needs a written explanation backed by proof — a CPA letter, a profit-and-loss statement, or evidence the dip was temporary. If the story doesn’t line up, most programs default to the lower, more conservative number. Investors who’d rather skip the personal-income conversation entirely sometimes move the deal to a rental-income-based structure instead.
Key Terms Defined
Bank statement loan. A mortgage that qualifies a self-employed or 1099 borrower using deposits from personal or business bank accounts instead of traditional personal-income documentation.
Expense ratio. A percentage the lender subtracts from your gross deposits to estimate real income, since not every dollar in the account is profit.
Lower-of logic. When a lender calculates income two different ways and uses the smaller number to qualify you — the conservative default when a trend looks uneven.
Trend test. A comparison of recent months against a longer average to see whether income is rising, flat, or sliding.
Reserves. Liquid funds left over after closing, measured in months of the future payment, that a lender wants to see sitting in the bank.
Why Lenders Look at the Trend, Not Just the Total
A single bad quarter rarely sinks a file on its own. What underwriters actually want to know is whether the dip is a blip or the new normal — and whether you can prove it.
That distinction drives the whole review. A borrower who took a lower draw for three months because they reinvested in equipment looks very different, on paper, from a borrower whose book of business is shrinking month over month. Both might show the same year-over-year percentage decline. Only one has a story that holds up.
This is where bank statement underwriting actually works in the borrower’s favor compared with a tax-return-based file. Deposits are deposits — they don’t care whether you wrote off a home office or depreciated a truck. On the agency side, Fannie Mae’s self-employed income guidance treats a declining trend as presumptively unacceptable unless it’s offset, and it runs that analysis off the taxable-income line from your returns. Bank statement programs skip that step entirely and go straight to cash flow. A declining taxable-income number on a Schedule C is frequently irrelevant to a bank statement file, because the file was never built on that number in the first place.
What Actually Counts as “Declining”
There’s no single universal threshold — this varies by lender and by how the rest of the file looks. What matters more is whether the decline is isolated to one period or shows up as a sustained slope across several months.
Underwriters typically run more than one comparison. They’ll look at the most recent three months against the trailing six, and both of those against the full 12- or 24-month window. If the recent months are flat or improving relative to the earlier period, a soft prior quarter often gets absorbed into the average without much friction. If the slope is negative across every window — three-month, six-month, and full-period — that’s the pattern that tends to draw a harder look and a request for explanation.
The 12-Month vs. 24-Month Choice Actually Matters Here
This decision changes your income number directly, and it’s worth thinking through before you apply. A 24-month lookback smooths out a single soft stretch by blending it with a longer, presumably stronger, history. A 12-month lookback reflects only the most recent year — better if that year was strong, worse if it was the down year itself.
Say an investor’s business had a strong first year and a softer second year because a major client left mid-cycle. Documented with the client-loss timeline and evidence the account has since been replaced, a 24-month statement package can average the two years together rather than letting the softer year stand alone. Flip the scenario — strong recent months following a rough stretch further back — and a 12-month window captures the recovery without dragging the old low months into the average at all.
Running the Trend Test: What Underwriters Actually Do
The mechanics are straightforward once you see them laid out. First, eligible deposits get totaled and non-income credits — transfers, loan proceeds, one-time gifts — get stripped out. Transfers from the borrower’s own business into a personal account are the exception: those count in full, at 100%, because that money already represents earned business income moving accounts.
Second, an expense factor gets applied to business-account deposits to estimate what’s actually profit versus what covers overhead. On most bank statement programs in Lendmire’s wholesale network, that factor runs on a sliding scale that increases with staff size and shifts higher still for product-based operations rather than pure service businesses. An accountant-provided ratio or a profit-and-loss method (capped around 80%) is also available on many files when the standard fixed ratios don’t fit the business model.
Third comes the trend test itself — rolling three- and six-month windows checked against the longer average to see whether the slope is negative and how steep it is.
Fourth, if the recent number and the trailing average disagree, most programs default to lower-of logic: the more conservative of the two figures carries the file, unless the borrower’s documentation supports normalizing to something higher.
Writing an Explanation That Actually Holds Up
A weak explanation is vague and defensive. A strong one is specific, dated, and backed by something a reviewer can independently check.
The explanation needs three pieces, and skipping any one of them weakens the whole thing:
- What caused the decline. Name the specific event — lost a client, changed business models, took parental leave, scaled back to launch a new service line. Vague phrasing like “business was slow” invites more questions, not fewer.
- Why it was temporary or already reversed. Point to a specific month or quarter where deposits stabilized or turned back up, and reference the recent statements that show it.
- What proves it. A signed CPA letter, an updated profit-and-loss statement, an invoice showing a new client contract, or a year-to-date deposit summary that already reflects recovery. Underwriters aren’t looking for a compelling narrative on its own — they want the narrative and the paper trail to match.
Common documented stories that tend to hold up: a self-employed owner reinvesting in growth while draws temporarily dipped but underlying deposits stayed healthy; a 1099 sales professional who lost one large account and replaced it with a new book of business; an independent contractor who left a W-2 job mid-year and only has a partial year of self-employed deposits to show. None of these automatically qualify — but each gives an underwriter something concrete to weigh instead of a blank number.
Where the narrative doesn’t line up with the statements — or there’s simply no documentation behind the claim — most files fall back to the conservative, lower-of number by default rather than the borrower’s preferred version of events.
Underwriting Technology Is Already Watching for This
Worth knowing before you apply: automated income-verification tools built for non-QM underwriting now flag declining-income patterns automatically during the first pass on a file. That means the trend test often happens before a human underwriter ever opens the statements — the explanation and supporting documentation should be ready to submit alongside the application, not added after a request comes back.
When Bank Statement Documentation Isn’t the Right Fit
For a real estate investor specifically, there’s a second path worth knowing about: sidestep the personal-income conversation entirely by qualifying the property instead of the person. A DSCR loan — short for debt-service coverage ratio, meaning the loan is reviewed primarily on the property’s rental income covering the payment, subject to lender guidelines — doesn’t run a personal deposit trend test at all. Lendmire’s complete DSCR loans guide walks through how that qualification actually works.
This matters more than it might seem. A softening personal-income year is, structurally, a non-issue on a file that is reviewed on the property’s own cash flow rather than the owner’s deposits. If the property covers its payment on paper, a personal down year doesn’t enter the math the same way. That’s a materially different risk profile — and it shows up in performance data too. Investor DSCR loans have held impairment rates around 6% since the start of a recent period, a notably calmer picture than CPA-and-P&L or 12-/24-month bank statement files, which have been running closer to 11% in the same stretch. That gap is worth knowing before choosing which qualification path to pursue on a purchase or refinance, especially for an investor weighing multiple properties across a portfolio.
The tradeoff cuts both ways. Bank statement loans exist because seasonal or lumpy self-employed income is genuinely hard to prove with two years of traditional personal-income documentation — the flexibility is real, in exchange for more paperwork and larger reserve requirements than a straightforward W-2 file. DSCR structures trade that personal-income flexibility for a different kind of scrutiny: the property’s rents, the lease terms, and the local rental comps become the file’s center of gravity instead. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Bank Statement Program Sizes and Leverage — What’s Actually Available
Through select wholesale programs, subject to full underwriting, bank statement financing for high-income self-employed borrowers runs from $300,000 up to $30 million across two distinct programs. A portfolio non-QM bank statement program carries files to $6 million; a separate bank portfolio jumbo program handles 12-month-statement files on its own size ladder — 65% loan-to-value to $5 million, 60% to $10 million, and 55% up to $30 million, with interest-only capped at 60% or the band’s own ceiling, whichever is lower.
Leverage on a primary residence steps down as the loan size climbs. Under $1 million, well-qualified borrowers can reach 90% financing. Move into the $2 million to $2.5 million range and the ceiling drops to 80%. Above roughly $3.5 million, every file moves to case-by-case review rather than a published maximum. Investment property leverage runs about five points lower than primary-residence figures at every comparable size band, and second-home leverage sits in between.
Documentation on the portfolio side typically runs 12 or 24 consecutive months of personal or business bank statements, with a 660 credit floor on that program (680 on the bank portfolio jumbo program, 700 above the super-jumbo threshold). Debt-to-income can run as high as 50% on many files. Reserve requirements scale with loan size — commonly three months of payments up to $500,000, six months up to $1.5 million, and nine months above that, plus additional reserves for each other financed property an investor already holds.
Cash-out works differently depending on leverage. Below 60% loan-to-value, proceeds are generally unlimited on the portfolio program; above 60%, cash-in-hand is typically capped at $1.5 million. There’s no published cap on the separate bank portfolio jumbo program’s cash-out structure.

The Misconceptions That Trip People Up
“Non-QM means no verification.” Not true. Non-QM just means the loan sits outside the Qualified Mortgage box — it doesn’t mean there’s no underwriting behind it. Every deposit still has to be sourced and explained before it counts toward income.
“A down year automatically kills the file.” Most programs run a graduated response instead — trend tests, lower-of calculations, and normalization when the story is documented — rather than a flat decline. A soft year with a clean explanation and a full 24 months of history often clears without much drama.
“The expense ratio is the same everywhere.” It isn’t. Ratios and acceptable documentation types vary meaningfully by lender and by program, which is part of why shopping a file through multiple wholesale programs matters.
“Bank statement and DSCR loans solve the same problem.” They don’t. One qualifies the borrower off their own deposits; the other qualifies the property off its rents. A declining personal-income trend is a bank-statement-file issue — it generally isn’t a DSCR-file issue at all.
Tax treatment can depend on how funds are used and how a property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction tied to a bank statement or DSCR transaction.

Frequently Asked Questions
Does a one-time bad month ruin a bank statement application? Usually not. Underwriters run rolling three- and six-month windows against the longer average specifically to separate a single soft month from a real trend. One weak month inside an otherwise stable 12- or 24-month history typically gets absorbed into the average rather than driving the coverage figure down.
Should I choose a 12-month or 24-month statement package if my income dipped recently? It depends on where the dip sits in your history. If the soft period is further back and recent months are stronger, 24 months usually helps by diluting the low stretch. If the dip is the most recent period, a 12-month window built on an earlier, stronger year may actually hurt more than help — a 24-month blend is often the safer choice in that case.
Can a CPA letter alone fix a declining-income file? It can strengthen one, but it’s rarely sufficient by itself. Underwriters generally want the letter paired with statements or a profit-and-loss document that supports the same story — cause, timing, and evidence of recovery all pointing the same direction.
Is it better to wait a year and reapply instead of explaining the decline now? That depends on the trajectory of the business and the property window an investor is trying to hit. Waiting adds a fresh comparison year, which can help if income is genuinely recovering — but it also means losing the current deal. A well-documented explanation today is often the more practical route for a specific purchase.
Do investors with declining personal income ever just skip bank statement loans entirely? Some do, particularly when the rental property itself produces enough income to cover the payment. In that case, a DSCR structure lets the personal deposit trend sit outside the qualifying math altogether, which is part of why some investors move straight to that path rather than fighting a soft year on paper.
If you’re weighing a bank statement application against a rental-income-based structure, or trying to figure out which fits a specific deal, Lendmire can help compare the options based on the property, the documentation available, and the numbers behind the file.
