What are you analyzing?
Investors think in deals, not in formulas. Pick the path that matches what’s on your desk right now.
I’m analyzing a rental
Will it cash-flow? Is the cap rate competitive? How does this stack up against other deals?
I’m analyzing a flip
What’s the ARV? What’s my max offer? Is there enough margin to justify the rehab risk?
I’m financing a deal
What’s the monthly payment? Will the property qualify for a DSCR loan? How much down do I need?
Every tool comes with the explanation.
Each calculator has a step-by-step guide that walks through the formula, the assumptions, and how investors actually use it.
The calculators investors keep coming back to.
Start here. Three guides, in order.
The fastest way to go from “I think this looks good” to “I can defend this number to a partner or a lender.”
