The sequence

One loop. Every deal.

Every workflow follows the same defensible sequence investors use:

Step 1

Calculate

Run the chain. Each calculator pulls inputs from the last one, so you're never re-typing the same NOI into three different forms.

Monthly Cash Flow$412
Step 2

Save the deal

Hit Save Deal at any step. The full input snapshot lands in your Dashboard with metrics, tags, and notes attached.

FAQ

Common questions.

Yes. Every calculator uses the exact formulas relied on by working investors, commercial lenders, and CFA programs. Each metric includes a matching guide showing the formulas, assumptions, and typical benchmarks so you can verify the math yourself.
In your browser, on your device — full stop. We don't store your property inputs, deal histories, or notes on any server. Clear your local browser storage and it's gone. If we introduce account-based sync later, we'll be fully transparent about how your data is handled.
No. Every calculator, plain-English guide, step-by-step workflow, and the Deal Dashboard works instantly without signing up. No email forms, no tracking pixels, no paywalls on the math.
Because real underwriting isn't one calculation — it's a sequence. A workflow strings the tools together in the order pros run them. The income from your cap rate flows automatically into your mortgage math, net cash flow, and DSCR. You skip the re-typing, and the numbers stay internally consistent.
Yes. All calculators, guides, and workflows are completely free. The Deal Dashboard is free during beta and will remain free for basic use. If we add premium features later — like PDF exports or team deal sharing — the core math and underwriting tools will stay free.
Yes. Every component is fully responsive. The Dashboard stacks cleanly, filters collapse into a compact strip, and workflows scroll smoothly on a phone. You can underwrite a property from a parking lot.
