1099 Loan Handles One Declining Year Of Deposits — The Quick Read: Most 1099 loan programs do not average a down year with a stronger one. When income drops year over year, underwriters generally use the lower of the two years to calculate qualifying income. A modest, explainable dip usually survives with documentation. A steep or unexplained collapse can sink the file entirely — which is exactly where a rental-property investor should start weighing a different kind of loan altogether.
The Core Rule: Lower Year Wins, Not the Average
Here’s the rule in one sentence: if year two is lower than year one, the file gets underwritten on year two’s number, not a blended average of the two.
This mirrors long-standing agency logic on self-employed income. Fannie Mae’s own cash-flow methodology treats rising or flat income as usable at face value, but flags a downward trend for closer scrutiny under its Form 1084 framework, per the Fannie Mae Selling Guide. Non-QM programs — including most 1099 loan products — borrowed that same instinct. Stable or growing income gets the benefit of the doubt. Declining income does not.
Why the lower year and not a middle-ground average? Because the lender isn’t trying to reward a good year that already happened. They’re trying to predict next year. A borrower whose income fell from one year to the next is, statistically, more likely to keep falling than to snap back — so the conservative number becomes the safer bet for underwriting purposes.
Key Terms Defined
1099 loan — a mortgage that qualifies a borrower using gross income reported on IRS Form 1099, instead of W-2 wages or net income from traditional personal-income documentation.
Bank statement loan — a mortgage that qualifies a borrower on deposits into personal or business bank accounts, applying an expense ratio to estimate real income rather than relying on a 1099 or tax return.
DSCR loan — a business-purpose loan for rental property that qualifies primarily on the property’s own rental income covering the payment, subject to lender guidelines, rather than the borrower’s personal income.
Expense ratio — the percentage of gross deposits an underwriter assumes goes to business costs before counting the rest as usable income.
Lower-of-two-years method — the underwriting convention where declining income across two documented years is qualified using the lower year’s figure instead of an average.
Reserves — liquid funds a borrower must have left over after closing, measured in months of the future housing payment.
How the Two-Year Comparison Actually Works
Underwriters don’t just glance at a single 1099 form. They pull one to two years of documentation and line the totals up side by side.
Say a self-employed consultant’s 1099 income ran higher in year one and fell in year two. The underwriter compares the two totals directly. If year two is lower, that alone triggers the declining-income determination — no averaging, no giving credit for the stronger prior year.
From there, the file usually needs a written explanation. A lost client, a slower market for that trade, a temporary health issue — whatever the reason, it gets documented, not assumed. Underwriters want to see whether the drop was a one-time event or the start of a longer slide. Contracts signed since the drop, new client onboarding, or a rebound in the current year’s activity can all support the argument that the dip was temporary.
This is where a single declining year differs meaningfully from a multi-year downward trend. One rough year with a documented reason and signs of recovery is a manageable underwriting problem. Two or three years running downhill is a much harder story to tell.
When a Single Bad Year Isn’t Fatal
A modest, well-documented dip is common and rarely kills a 1099 file on its own. What actually determines the outcome is the size of the drop and whether the borrower can explain it credibly.
A borrower whose income slipped by a small, single-digit percentage typically clears underwriting without much friction, especially with a letter explaining the cause. A steeper drop — say, income cut by a third or more — pushes the file into deeper scrutiny. At that point, underwriters start asking whether the business itself is in trouble, not just whether last year was slow.
Current-year activity matters here too. If the borrower’s most recent months show deposits and 1099 activity trending back up, that strengthens the case that the prior decline was temporary rather than structural. Underwriters weigh trajectory, not just the two static year-end totals.
One practical option some brokers reach for when a straight 1099 comparison looks weak: a profit-and-loss-based approach that lets an accountant document current-year performance directly, rather than relying solely on last year’s tax paperwork. Lendmire’s team has covered when a P&L loan can qualify after one rough year in more detail for borrowers weighing that route.
What Happens When the Decline Is Too Steep
Here’s the honest answer: a severe enough drop can get the income disregarded entirely, not just discounted. Underwriters distinguish between a business that had a rough patch and one that may be failing.
There’s also a hard floor worth knowing about, even outside the 1099-specific space. In federal guidance on rural housing income, negative business income doesn’t subtract from other qualifying income — it’s simply treated as zero, per USDA Rural Development’s income guidance. A loss year contributes nothing; it doesn’t drag the rest of the file down with it. That same “floor at zero, don’t go negative” instinct shows up across conservative underwriting more broadly, even where it isn’t spelled out in writing.
If the decline looks less like a bad year and more like a business winding down, most 1099 programs simply won’t get there — no amount of variance-letter writing fixes a business that’s genuinely shrinking. That’s the moment to stop trying to force a personal-income loan and look at the property itself instead.
The DSCR Alternative: Skip the Personal-Income Question Entirely
If a rental property is the actual goal, none of this may need to matter. A DSCR loan is reviewed primarily on the property’s rental income covering the payment, subject to lender guidelines — not on last year’s 1099s, traditional personal-income documentation, or deposit history. For an investor whose Schedule C or 1099 income took a hit, that’s often the more direct financing path.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Across the deals Lendmire’s network sees, DSCR loans typically run from $300,000 up to several million dollars, with leverage that steps down as loan size climbs — often in the 80% range on smaller investment-property purchases and tightening at higher balances, always subject to credit and lender guidelines. Reserve requirements generally scale with loan size too, commonly landing in the 3-to-9-month range depending on the file. None of that depends on whether the borrower’s 1099 income rose or fell last year.
That said, one declining year with a strong explanation doesn’t automatically mean a borrower should abandon a personal-income loan for DSCR — it means it’s worth comparing both paths. Lendmire’s complete DSCR loans guide walks through how the property-income qualification actually works, including scenarios where it clears the bar even when the borrower’s personal financials wouldn’t. For an investor whose income dipped for a reason unrelated to the rental property itself — a slow year in a day job business, a temporary contract gap — the property’s own numbers may simply make the whole personal-income conversation irrelevant.
| Factor | 1099 Loan | DSCR Loan |
|---|---|---|
| Reviewed on | Borrower’s 1099 income, lower of two years | Property’s rental income vs. payment |
| Declining income impact | Direct — triggers lower-year rule | None — personal income not reviewed |
| Documentation focus | Variance letter, trend explanation | Lease, appraisal, rent schedule |
| Best fit | Owner-occupied purchase, stable trajectory | Rental property, any personal income history |
The math works differently depending on the property and the borrower’s broader picture — a modest single-year dip on a strong long-term earner is a very different underwriting conversation than a multi-year slide. Comparing both a personal-income path and a property-income path side by side, before committing to one, is usually the smarter move. Lendmire’s earlier coverage of whether one declining deposit year can kill a file digs deeper into that decision for borrowers still weighing bank statement financing.
This is not legal or tax advice, and none of this replaces a conversation with a qualified attorney or CPA about a specific borrower’s situation, business structure, or tax filings.

Frequently Asked Questions
Will one declining year automatically disqualify a 1099 borrower?
No. Most programs use the lower year’s income rather than rejecting the file outright, provided the drop is moderate and explainable. Outright disqualification is more common with a severe, unexplained, or multi-year decline than with a single soft year.
Can a borrower ask the lender to average the two years instead?
Generally no. The industry convention runs the opposite direction — averaging applies to flat or rising income, while a documented decline typically triggers the lower-of-two-years calculation instead.
Does strong current-year income offset a prior bad year?
It can help the narrative, even though it doesn’t erase the lower-year calculation itself. Underwriters weigh trajectory alongside the raw numbers, so recent months of stronger activity can support the case that the decline was temporary.
What if the decline happened because a borrower switched from W-2 to 1099 work?
That’s a different issue than a decline — it’s a continuity question. Underwriters may classify a recent W-2-to-1099 switch as a shift into self-employment, which can require its own history and documentation regardless of whether income actually went up or down.
Is a bank statement loan easier than a 1099 loan when income is declining?
Not necessarily easier, but it can tell a different story. Bank statement programs look at deposits rather than 1099 totals, which sometimes paints a stronger current picture — though a genuine, sustained earnings decline can still limit qualifying income under either approach.
