Why this toolkit

You've seen the free spreadsheets.

Most "free" investor calculators exist to get your email into a software funnel. This isn't that.

Instead of

  • A $30/month subscription you forget to cancel
  • A free spreadsheet with a formula quietly broken
  • Guessing what "good" even looks like
  • One calculator, and starting over for the next deal type

You get

  • One purchase, yours forever — no subscription
  • Every formula protected and verified before it shipped
  • Built-in benchmarks so you know what to look for
  • Five tools covering the whole investor journey
The tools

One for every stage of the deal.

Buy them individually, or get all five below for less than the price of three.

Questions

Before you buy

Every tool works natively in Excel and Excel for Mac. They also open in Google Sheets — upload the file to Drive and open with Sheets. One small note: Excel's cell-locking doesn't carry over automatically, so re-enable it in Sheets under Data > Protect sheets and ranges if you want it.
No. These are calculation tools to help you organize and analyze your own numbers, not investment, legal, or tax advice. Always verify with a licensed professional before making a purchase decision.
Yes — the Rental Portfolio Tracker is built for exactly that, supporting up to 8 properties out of the box (more with a simple copy-down of the formulas).
Reach out within 7 days of purchase and we'll sort it out. (Placeholder — replace with your actual refund policy once your storefront is set up.)
