The six numbers that decide your deal

Not a "rental calculator". The underwriting logic a DSCR lender runs on your file — in a workbook you control.

DSCR, the lender way

Stabilized basis with your ramp-up kept separate — the detail most templates get wrong, and the first thing an underwriter checks.

36-month seasonal cash flow

Twelve monthly ADR and occupancy inputs — not one fake average. See the winter dip before it sees you.

Break-even occupancy

The single number that tells you how much cushion you really have if bookings soften.

Cash-on-cash & 5-year IRR

Year-by-year returns on your real cash in, with exit assumptions you control.

Sensitivity matrix

ADR ±20% × occupancy ±20%, color-coded on both cash-on-cash and DSCR. Know your downside in one glance.

Lender-ready dashboard

KPI cards and charts formatted to share with your lender or partners — no cleanup needed.

What the default deal looks like

The model ships with a realistic $400k purchase financed with a DSCR loan at 7.5%/30y — credible numbers, not brochure fantasy. Replace them with yours in minutes.

Questions, answered

Does it really work in Google Sheets?

Yes. The workbook uses only Sheets-compatible functions — no macros, no add-ins, no external links. Upload the .xlsx via File → Import and everything recalculates.

I'm not a finance person. Can I use this?

That's exactly who it's built for. You only ever type in the yellow input cells; the START HERE sheet walks you through your first pro forma in about 10 minutes, and the 13-page guide explains every output in plain English.

How is this different from free calculators?

Free tools give you one average month and a single ROI number. This model underwrites like a lender: stabilized DSCR, seasonal monthly cash flow, financing scenarios, break-even occupancy and a full sensitivity matrix — with every formula visible and machine-verified.

What if it's not for me?

30-day money-back guarantee through Gumroad. No questions, no friction.

Do I get updates?

Yes — you buy v1.0 and future updates to this model are free. Gumroad notifies you automatically when a new version ships.
