Fast-running tools, plain-English guides, and live workflows built to defend your numbers. No spreadsheets. No sign-up. No nonsense.
A 30-second first pass that tells you whether a deal deserves deeper underwriting.
Not just calculators — full sequences that mirror how investors actually analyze deals.
You're buying a long-term rental. Walk from cap rate to annualized ROI with debt service in between.
Buy · Rehab · Rent · Refinance · Repeat. See exactly how much capital you'll get back out.
Buy, rehab, sell. Project the bottom-line profit and the ROI on the cash you'll actually deploy.
Compare the true cost of buying against renting over your time horizon — with the break-even year.
Every workflow follows the same defensible sequence investors use:
Run the chain. Each calculator pulls inputs from the last one, so you're never re-typing the same NOI into three different forms.
Hit Save Deal at any step. The full input snapshot lands in your Dashboard with metrics, tags, and notes attached.
Line any deals up against each other. Best and worst values are flagged automatically, so the right deal makes itself obvious.
Every metric, every formula, every assumption — explained without jargon.
Cap rate, cash flow, DSCR, ARV, MAO, mortgage math, and more — every number you need to underwrite a deal, all running in your browser.
The "why" before the "how." Each guide walks through the formula, the assumptions, the benchmarks, and how seasoned investors actually use it.
Move from “I think this looks good” to a number you can defend to a partner or a lender.
The baseline metric every other calculation depends on. Get NOI right and your entire underwriting sits on solid ground.
