The Self-Employed Borrower with a Declining Schedule C
A borrower who is a sole proprietor applies for a $420,000 loan to buy a $525,000 house with 20% down. Her two most recent Schedule C returns show net profit of $112,400 and then $96,200; the decline is not explained by any one-time event, and add-backs for depreciation and business use of home are already included in those figures. The 30-year fixed rate is 6.75%, giving $2,724 principal and interest; property taxes are $548, hazard insurance $135, and HOA dues $92 per month. Other debts: an auto loan at $468 with 14 payments remaining, student loans at $215, and a credit card minimum of $85. After closing she will have $14,600 in the bank, of which $9,000 is a documented gift from her sister.
1. Which income figure should the underwriter use, and why does the choice decide the file?
Read the worked answer
Two-year average: ($112,400 + $96,200) ÷ 2 = $104,300, or $8,692 per month.
Most recent year: $96,200, or $8,017 per month.
Self-employed income is analyzed for stability, not just averaged. A decline from $112,400 to $96,200 is a 14.4% drop with no documented one-time cause. Under standard underwriting practice, an unexplained decline of that size means the underwriter uses the lower, most recent year - the reasoning being that the trend, not the average, predicts the borrower's capacity to pay. The borrower could overcome this by producing a signed year-to-date profit and loss statement, current business bank statements, and a written explanation showing that the drop came from a nonrecurring item (a lost one-time contract, a equipment purchase expensed under Section 179, a COVID-type disruption). Absent that, $8,017 is the number.
The choice is decisive because it moves the back-end ratio across the program limit - see the next task.
2. Compute the front-end and back-end ratios under both income figures and assess whether the loan is approvable.

Housing expense (PITI): $2,724 + $548 + $135 + $92 = $3,499
Other monthly obligations: $468 + $215 + $85 = $768 (the auto loan has 14 payments left; only installment debt with roughly 10 or fewer payments remaining may be excluded, so it counts)
| Income used | Front-end ($3,499 ÷ income) | Back-end ($4,267 ÷ income) |
|---|---|---|
| $8,017/mo (lower year) | 43.6% | 53.2% |
| $8,692/mo (average) | 40.2% | 49.1% |
Assessment. Conventional program guidelines generally top out around 45%–50% back-end, with the strongest files at or below 45%. At 53.2% the file fails on the lower-year income. Even at the average, 49.1% is a high-ratio file requiring compensating factors - and there are few here: the income is declining, and the reserve position includes gifted funds.
Also confirm that under the ability-to-repay rules the lender has documented and verified income using reasonably reliable third-party records; a lender who simply averaged a declining Schedule C without analysis has an ATR problem, not just a guideline problem.
3. What are the realistic fixes, and which one creates a new problem?
Read the worked answer
Fix 1 - Retire the auto loan. Paying off $468 per month drops the back-end to ($3,499 + $300) ÷ $8,017 = 47.4%, and to 43.7% on the averaged income. But the payoff has to come from somewhere: if she uses $6,900 of her $14,600 in cash, reserves fall to about $7,700.
Fix 2 - Reserves. Two months of PITI is $6,998. She technically still clears that, but the reserve requirement generally must be met with the borrower's own funds; the $9,000 gift may fund closing costs and down payment, but it cannot be counted toward reserves. Stripping out the gift leaves $5,600 of own funds after closing - short of $6,998. So Fix 1, funded from her own cash, makes the reserve problem worse rather than better.
Fix 3 - Reduce the loan. A larger down payment shrinks P&I; each $10,000 down removes roughly $65 per month, so the improvement is slow and requires cash she does not have.
Fix 4 - Add a co-borrower or reduce the purchase price. Either is more efficient than debt payoff.
Fix 5 - Document the income drop as nonrecurring. The best fix is not arithmetic at all: get a CPA letter and year-to-date P&L showing the business is on pace for $110,000 or better. That restores the higher qualifying income and solves front-end, back-end, and reserves at once. If she cannot produce that documentation, the file is a decline regardless of how the debts are shuffled.
