A 1099 mortgage is a self-employed mortgage that qualifies you on the gross income reported on your 1099 forms — not the taxable income left on your 1040 after write-offs. For real-estate agents, sales professionals, consultants, and any contractor paid as a 1099, this is often the difference between qualifying for the home you want and being told "no" by a bank that can't read how you actually earn.
The mechanics are simple. Mbanc reviews 12 or 24 months of 1099 forms, sums the gross income across all payers, applies a fixed 10% expense factor, and divides by the number of months. The result is your qualifying monthly income. That income then has to clear a debt-to-income (DTI) ceiling of 50%, and the loan size has to fit within Mbanc's LTV grid based on your credit score and the property value.
"A 1099 borrower with $300,000 of gross income is a serious earner. A conventional bank looks at their tax return, sees $120,000 net after every legitimate write-off, and tells them they qualify for a townhouse. We look at the 1099 and qualify them for the house they actually want. The income is real either way."
— Mayer Dallal, Managing Director, Mbanc
Why the 90% factor exists. A 1099 contractor has real business expenses — vehicle, home office, equipment, professional fees, marketing — and the IRS rewards those write-offs by reducing your taxable income. Smart tax strategy lowers your tax bill but obliterates your conventional mortgage qualification. The 90% factor (a fixed 10% deduction) is Mbanc's standardized estimate of typical contractor overhead — much closer to your actual cash flow than your tax return shows.
The three things that determine your maximum loan amount:
- Your qualifying income — calculated as 90% of your gross 1099 income, divided by 12 or 24 months. Sets the DTI-based ceiling for what you can afford.
- Our program ceiling — Mbanc's core Non-QM 1099 program caps loans at $3 million. Larger loans are available via portfolio quote.
- Your property & LTV cap — a separate check driven by credit score, loan size, property type, and loan purpose. At 720+ FICO on a primary purchase, Mbanc lends up to 85% LTV on loans up to $1.5M, stepping down to 75% LTV above $2.5M.
The calculator's headline number is your income capacity — what you qualify for based on your 1099s, capped at $3M. The "Your scenario" panel below the headline does the property/LTV check for the specific transaction you're modeling. That separation matters: a 1099 borrower with strong income can be income-capable of a $3M loan but constrained by the property they're buying. The calculator surfaces both so a Principal Banker can talk through both levers.
About the 8% rate this calculator uses. The Non-QM market moves with broader rate conditions, and recent weeks have been particularly volatile. Rather than anchor to a specific rate that may be stale in a week, this calculator uses a flat 8% assumption — conservative enough that your real rate, determined at full underwriting, is typically lower. If you qualify at 8%, you qualify at the rate you'll actually get. If the math tightens at 8%, your Principal Banker can re-run the file at today's actual rate and often finds the headroom.
