One screen for every way to make money on a property.
ROIStack started because we got tired of running the same property through four different calculators, and getting four different conclusions. So we built one tool that scores every exit from one set of inputs.
Why we built it
Most rental calculators were built around a single strategy. If you're a long-term buy-and-hold investor, that's fine. But the moment you want to compare a property as a BRRRR vs an STR vs a flip, you're in spreadsheet hell, and small differences in assumptions create wildly different verdicts.
ROIStack's Omni-View was designed to fix exactly that: one set of property and financing inputs, four side-by-side strategy analyses, and a single deal score per strategy so you can see which exit actually wins.
Everything else, the sensitivity tornado, the AI assistant, the branded PDF reports, the offline-ready PWA, exists to keep you in flow while you underwrite.
What we believe
Honest math
We show you the formulas and assumptions. No hidden fudge factors. If a number looks too good, we tell you why.
Fast over fancy
Underwriting a deal should take 60 seconds, not 60 minutes. Every interaction is built to keep you moving.
Your data, your control
Saved deals are yours. Export to CSV anytime. Delete your account anytime.
Built for real investors
We use ROIStack to underwrite our own deals. If it doesn't help us, it doesn't ship.
