How the flow works

  1. 01Tap “Screen a deal” to start, then set the bar you want the deal to clear.
  2. 02Pick your goal — Hold, Sell, or Hold after building value.
  3. 03Answer about twelve plain-English questions about the property.
  4. 04Read the verdict: the call, the three numbers behind it, and the solved price.
This is an educational screening tool. The Deal Score is an estimate built from your own inputs and targets — not investment, lending, or legal advice. Verify every number before you make an offer.
What you get

Five things the app actually does

Build or Bust is a screening tool, not a crystal ball. It tells you quickly whether a deal deserves more of your time.

The 60-second verdict

Always free. BUILD means go, WORK THE DEAL means pursue with conditions, BUST means walk. You get an answer before you spend a weekend in a spreadsheet.

Goal-first flow

Start with what you are trying to do — Hold, Sell, or Hold after building value — then set your bar. Newer and Experienced presets fill in cash-on-cash %, DSCR, and $/unit targets.

Three numbers + solved price

The verdict shows the three numbers that actually drove it, and the price at which the deal would work. No black box.

Depth runs on COVI

Sensitivity tables, exports, and deal packaging use COVI, which you earn in-app through the Academy. COVI is a utility token for platform activity — not an investment.

Milestones mint ELUV

Verified progress can mint ELUV, an ERC-5192 soulbound credential. Earned only, never sold, never transferable.

The verdict

Three possible answers

Every screen ends in one of three calls, with the reasoning shown rather than hidden.

BUILD

Clears your gates with room to spare. Go get it — after you verify every number.

WORK THE DEAL

Close, but conditional. The app shows which lever to pull and what price makes it work.

BUST

Does not clear the bar you set, and the gap is not fixable at a sane price. Move on.

Build or Bust is the flagship, not the whole platform. Apps, games, materials, and collectibles all live in the marketplace.
