The 2-year history rule
Fannie Mae, Freddie Mac, FHA, VA, and USDA all default to the same starting point: two full years of self-employment history, documented with signed personal tax returns and — if you own 25% or more of a business entity — signed business returns for the same period.
The "two years" is a floor, not a target. Underwriters want a trajectory: is income stable or improving? If year 2 is lower than year 1, they use the lower year (not the average) and may require a written explanation.
Exceptions that let you close with one year:
- Two prior years as a W-2 employee in the same line of work (Fannie/Freddie).
- Strong FHA file with a compensating factor and a solid one-year return.
- Bank statement or P&L loan programs (see below).
Net profit vs gross revenue: what actually counts
This is where most self-employed borrowers get blindsided. Your qualifying income is not what you deposit into your business account. It's the net profit that appears on your tax return after you subtract every deductible expense you claimed to reduce taxes.
Qualifying income = 2-year average of (net profit + allowable add-backs)
The more aggressively you write off expenses, the less mortgage you qualify for. This trade-off is the single biggest planning decision self-employed buyers make in the 12–24 months before applying.
Add-backs that raise your qualifying income
Lenders add back non-cash expenses because you didn't actually spend that money — you just deducted it. The most common add-backs:
Almost always added back
- • Depreciation
- • Depletion
- • Amortization / casualty loss
- • Business-use-of-home
- • One-time non-recurring losses
Sometimes / documentation required
- • Business-vehicle mileage (miles × IRS rate)
- • Meals & entertainment (varies)
- • Owner health-insurance premiums
- • 401(k) / SEP contributions (Freddie Mac only)
How lenders read each business type
| Entity | Forms reviewed | Key figure |
|---|---|---|
| Sole prop / 1099 | Schedule C | Net profit + add-backs |
| Single-member LLC | Schedule C (default) | Net profit + add-backs |
| Partnership / multi-member LLC | 1065 + K-1 | Ordinary income + guaranteed payments |
| S-corp | 1120S + K-1 + W-2 wages | W-2 wages + K-1 ordinary income (if 25%+ owner) |
| C-corp | 1120 + W-2 | W-2 wages only (retained earnings excluded) |
If you own 25% or more of a business, expect to provide two years of that entity's returns even if your personal income looks strong on its own.
Bank statement loans: the alternative when tax returns don't work
If your tax returns understate what the business actually earns, a bank statement loan qualifies you on 12 or 24 months of deposits instead of tax returns. Typical terms in 2026:
- Down payment: 10–20% (higher for lower FICO).
- Credit: 660+ typical minimum; best pricing at 720+.
- Rate premium: 1–2% above a comparable conventional rate.
- Income math: average monthly deposits × expense factor (usually 50%, can be as low as 15% with a CPA-prepared P&L).
- Reserves: 6–12 months of PITI in liquid accounts.
Bank statement loans are portfolio / non-QM products — the pricing is real, but they close, and they're the right tool when tax planning would cost more than the rate premium.
The 12–24 month prep playbook
- Stop aggressive write-offs two years before you apply. Every $10k you deduct this year is roughly $30k of buying power gone.
- Pay yourself a real W-2 salary if you're an S-corp. Bumping the W-2 portion of your S-corp comp adds documentable, non-declining income.
- Keep business and personal accounts fully separated. Commingled deposits kill bank statement loan qualification and slow full-doc approvals.
- File on time — never on extension the year you apply. Lenders need a filed, signed return; an extension pushes closing.
- Build 6+ months of reserves in liquid accounts. Reserves offset income volatility and unlock stretched DTI on Conventional.
