Contractor Home Affordability Calculator: What Can You Borrow in 2026?

If the monthly payment shown fits comfortably into your budget, you're likely in range to qualify—next step is to confirm your actual rate with a lender who works with 1099 income and alternative documentation. The final rate depends on your credit profile, down payment size, and the specific loan program (bank statement, stated income, or non-QM) the lender offers.

For self-employed contractors and construction business owners, how to qualify for a mortgage as a contractor is rarely straightforward. Traditional lenders want to see W-2 income or two years of consistent 1099 filings; they often back out depreciation, vehicle expenses, home office deductions, and other write-offs that reduce your taxable income on paper. That's where bank statement mortgage for construction owners programs, stated income loans, and non-QM loans for contractors fill the gap. This calculator estimates what you can afford using a debt-to-income (DTI) framework that mirrors how alternative lenders underwrite self-employed borrowers in 2026.

The key insight: lenders don't evaluate your tax return net income; they evaluate your actual monthly cash draw or average business income from bank statements and profit-and-loss statements. That number is usually higher than your taxable income, which means you may qualify for more house than you think. However, your contractor DTI limits still cap your total monthly debt (mortgage + car + credit cards + business lines) at 43–50% of gross income, depending on the program.

What changes your rate / answer

• Credit score: Lower scores push rates up 0.25–1.5% and tighten approval odds. Scores under 620 may require a co-signer or larger down payment.
• Down payment: 10–15% is typical for stated-income or bank-statement loans; 20%+ improves your rate and removes PMI. Larger down payments also reduce lender risk on self-employed borrowers.
• Debt-to-income ratio (DTI): Lenders cap your total monthly debt at 43–50% of gross income (higher for non-QM products). Existing car loans, credit card minimum payments, student loans, and business lines of credit all count against this ceiling.
• Loan term: Longer terms (30 years vs. 15) lower your monthly payment but cost more in interest; shorter terms may not fit your monthly cash flow.
• Documentation type: Bank-statement loans and stated-income programs price 0.5–1.5% higher than conventional loans but waive the need for 2 years of tax return history. Non-QM lenders also typically accept recent business formation (12–24 months in business).
• Business stability: Lenders prefer contractors with 24+ months of documented income. Newer businesses or those with uneven income may face higher rates or lower approval amounts.

How to use this

• Enter your gross monthly business income: Use your average monthly draw, guaranteed income, or 24-month average if your income fluctuates. This is what lenders see on your profit-and-loss statement or bank statements, not your tax return net after deductions.
• List existing monthly debt: Include car payments, credit card minimum payments (not balances), student loans, child support, and any business lines of credit. This affects your DTI ceiling and your maximum affordable mortgage payment.
• Set your down payment: Higher down payments reduce your loan amount, improve approval odds, and lock in better rates. 15% is a safe starting point for self-employed borrowers; 20%+ is ideal if you have it.
• Adjust the rate: The default assumes a 2026 non-QM or bank-statement rate (~6.85%). Raise it if your credit is below 680, you're using stated-income documentation, or rates have risen. Lower it if you have a 740+ score and strong reserves.
• Read the max home price: This is your estimated purchase price if you put down the amount you entered. Actual approval depends on the appraisal, title search, full underwriting, and the lender's reserve requirements (typically 2–6 months of mortgage payments in savings).

Bottom line

This calculator estimates what you could afford—not what any one lender will approve. Use it to set a realistic search range before you talk to a lender who specializes in mortgages for self-employed contractors. Real approval turns on your full financial picture: 24+ months of documented income (bank statements, P&Ls, or tax returns), cash reserves (2–6 months of housing expense), credit history, and the lender's appetite for your specific income documentation type.

FAQ

Why is my result lower than I expected? If you have existing debt, your DTI ceiling shrinks. A $1,500 car payment, $200 in credit card minimums, and $500 in business line payments eat $2,200 of your borrowing power every month. Paying down consumer debt before you apply can unlock $50,000–$150,000 in additional buying power.

Can I use gross income or do I have to subtract deductions? For bank-statement and non-QM loans, lenders use your documented cash income (what comes in and stays available), not your tax-return net (after write-offs). If your P&L shows $120k in revenue but $40k in business expenses, lenders typically use closer to $80k—without requiring you to prove every deduction on your return. Stated-income programs may go even higher if you've established 24+ months of business history.
