Alternative Documentation Mortgages for Contractors 2026

If you're a self-employed contractor or construction business owner, traditional mortgage lenders have already told you the story: your write-offs, depreciation, and business deductions make your tax returns look risky, even if you're profitable and cash-flowing well. You need a lender who accepts the way you actually run your business.

What to know

Alternative documentation mortgages exist because traditional lending doesn't fit self-employed income. Conventional lenders count only base W-2 wages and documented bonuses. Non-QM lenders, portfolio banks, and alternative-doc specialists count what actually matters: cash flow, business assets, and bank deposits.

Here's how the main paths differ:

Product	Income proof	Credit floor	Down payment	Rate premium	Best for
Bank Statement Mortgages	12–24 months bank statements	620+	10–20%	+0.5–1.5%	Solid cash flow, inconsistent tax returns
DSCR Loans	Debt Service Coverage Ratio	620+	15–25%	+1–2%	Investment properties; income-focused
Stated Income Loans	Business revenue you state	700+	15–25%	+1.5–2%	High earners with clean credit
Non-QM Mortgages	Mix of the above	620–680	10–20%	+0.75–1.75%	Flexible qualification across profiles
Asset-Based Mortgages	Liquid/investment assets	620+	Varies	+1–2%	Low income on paper, strong net worth

Bank statement mortgages count deposits into your business or personal account over 12–24 months as income. Lenders divide total deposits by the number of months and apply a haircut (usually 65–75% of stated average). This works if you've been in business 2+ years and your deposits track your actual revenue. Most require a minimum deposit average of $10,000–$15,000 per month to qualify for a conventional purchase.

DSCR loans measure whether rental or business property income covers the mortgage payment plus other debt. The ratio is: (annual gross rental/business income) ÷ (annual debt payments). Lenders typically require a DSCR of 1.1–1.25. This sidesteps the tax-return problem entirely because a property's income speaks for itself. Rates run 1–2% higher than conventional, and down payments start at 15%. Closing typically takes 30–45 days.

Stated income loans let you declare your annual business revenue without full tax-return verification—the lender spot-checks bank deposits and business licenses instead. Credit thresholds are tighter (usually 700+), down payments higher (20%+), and rates premium by 1.5–2%. Use these only if you're genuinely uncomfortable submitting older years' returns.

Non-QM mortgages are the catch-all: they don't follow the Consumer Financial Protection Bureau's "qualified mortgage" rules, giving lenders freedom to count rental income, bonus structures, or asset-based income that conforming loans reject. Non-QM originations grew roughly 20% year-over-year through 2025. Rates typically sit 0.75–1.75% above conventional 30-year fixed, and credit minimums are 620–680. Processing takes 35–50 days.

Asset-based mortgages shift focus from annual income to liquid net worth. If you have $200k in savings, stocks, or retirement accounts, some lenders will count that as qualifying income (usually at a 20% haircut). Down payments vary widely, and closing is faster than traditional underwriting—often 20–30 days. This path works for contractors with lumpy income or recent business formation.

Key trip-ups:

• Lenders will still pull your credit and review 2 years of tax returns even if they don't qualify you on them. They use them to verify business legitimacy and check for red flags (IRS liens, fraud).
• Bank statement loans count gross deposits—they don't subtract payroll, rent, or materials. If you spend 70% of revenue on labor, your qualifying income will be much lower than your take-home profit.
• Down payments for alternative-doc loans are almost always higher than conforming (10–20% vs. 3–5%). Factor this into your target purchase price.
• Rate approval is slower. Budget 45–60 days for closing; expedited processing costs 0.5–1% more.
