The Underground Toolkit

Every calculator and script from the book. Free, and yours to keep.

You shouldn't have to build a spreadsheet from scratch after reading a book that told you to use one.

These are the actual tools — the same evaluation sheets I run deals through and the scripts I use on investor calls. Download what you need. There's nothing to install.

Where should I send them?

First name and email. That's the whole ask.

Here's what's waiting on the other side of that form.

Deal evaluation spreadsheets

Fix & Flip Evaluation

Three comps in, ARV out. Runs the 70% rule, the lump-sum method and ROI side by side, and tells you whether the asking price works.

Rental Evaluation

Income, every operating expense agents forget, financing, and the four metrics your buy-and-hold investors actually ask about: the 1% rule, cap rate, cash-on-cash, and DSCR.

BRRRR Evaluation

The flip math and the rental math in one sheet, then all three refinance scenarios at once — 75%, 70% and 65% — showing cash left in the deal and post-refinance cash flow for each.

The buyer database

Investor Buyer Database

Every investor's buy box as searchable fields, plus a deal filter: enter a type, an area and a price, and the MATCH column flags everyone who fits. A Fields & Tags tab documents every column and gives you the CRM tag structure to build when you outgrow it.

Scripts

The Investor Scripts

Every conversation in the book, word for word: the "We Buy Houses" call with all four objections, the Facebook introduction and DM, working a meetup, the property email, the monthly check-in and 45-day text, and how to ask for the referral.

Before you use any of it

The spreadsheets are tools, not appraisals. Your numbers are only as good as your comps and your repair estimate. Get a contractor's figure before you send a deal to an investor. The math can't rescue a bad rehab number.
