Non-QM vs Conventional: Which One Fits Self-Employed Income?
Conventional underwriting reads your tax returns. If your returns are optimized for taxes, they are usually not optimized for a mortgage.
Quick Answer
Conventional financing qualifies self-employed borrowers on net income after business deductions, while non-QM programs can use bank statement deposits, 1099 gross income, a P&L, or assets instead. Conventional is almost always cheaper when the tax returns support the payment; non-QM exists for when they do not. The deciding question is usually how much the business writes off and how long that pattern has been in place.
The core difference
Conventional underwriting uses net income after business deductions, averaged across two years. Non-QM bank statement programs use deposits with an expense factor applied. For a business with heavy depreciation or vehicle and home office deductions, the two methods can differ by tens of thousands of dollars in qualifying income.
When conventional still wins
- Your tax returns show strong net income for two consecutive years
- You want the lowest available rate and can document income traditionally
- You plan to remove PMI at 20% equity and hold the loan long term
When Non-QM wins
- Write-offs suppress net income while deposits stay strong
- You changed entity structure or started the business under two years ago
- You are buying a rental and want DSCR qualification with no personal income docs
- A recent credit event has not reached conventional seasoning
The cost of flexibility
Non-QM pricing generally runs 0.5% to 1.5% above comparable conventional. Many borrowers treat it as bridge financing and refinance into conventional once two clean years of returns exist.
