Underwriter's Note — Add-Backs
Items marked ★ ADD-BACK are non-cash expenses that reduce your taxable income but I add them back to your qualifying income. Depreciation, business use of home, and mileage are the most common. They lower your tax bill but they are not real cash outflows — so I give them back to you as qualifying income.
DISCLAIMER: This calculator is for educational purposes only and is modeled after the IRS Schedule C form structure. It does not constitute tax advice, accounting services, or a guarantee of mortgage approval. Actual qualifying income calculations vary by lender and loan program. Always consult a licensed CPA and mortgage professional for your specific situation.
