Built by a wholesaler doing 165 deals a year

Stop writing offers
you can’t close.

OffrStack pulls comps the way an appraiser weights them, runs statistical confidence on your ARV, and back-solves the offer your deal can actually survive. Underwrite a property in ten minutes, not forty-five.

WHAT OFFRSTACK DOES

One tool. The whole deal.

01

Comps that hold up.

Pulls active and sold listings, then weights each one the way an appraiser would — bed, bath, square footage, year built, distance, recency. No Zestimate guesswork. No spreadsheet copy-paste.

02

Math that survives the deal.

Back-solves your offer from rehab, closing, holding, and a profit floor you set. Two methods side-by-side: 70% rule for the kitchen table, profit/flip for full-economics underwriting.

03

Dispo packet, lock-ready.

When the deal locks, generate a buyer-ready packet — comps, ARV with confidence band, photos, the math. Hand it to your list without bouncing through three other tools.

HOW IT HELPS

From four tabs and a sticky note to one screen.

  • ×Switch to Zillow. Cross-check. Question Zestimate.
  • ×Open spreadsheet. Type ARV guess. Type rehab guess.
  • ×Calculate 70% rule on a sticky note.
  • ×Send fee that's wrong. Lose the deal in escrow.

FROM THE FOUNDER

“I built OffrStack because I was tired of watching wholesalers tie up sellers in contracts they couldn’t close — usually because their numbers were wrong from the start.”

I’ve closed 165 wholesale deals in the last twelve months across 25 states, and over a thousand in my career between wholesales, flips, and rentals. Before that, I was a finance and accounting major with a CPA background who fell into data analytics. I love numbers. I love real estate. OffrStack is what happens when I stop doing those things in separate browser tabs.

You don’t need to take my word for any of this. The numbers are what you should trust. Run a deal you already closed through OffrStack and see what comes back.

ONE NOTE BEFORE YOU SUBSCRIBE

If you’ve never closed a deal, don’t buy this yet.

OffrStack will give you confident comps and math-backed offers — but you still need to know whether a property needs a $15-per-square-foot light refresh or a $45-per-square-foot full gut. Critical thinking is required. Do a deal first. Then come back. We’ll be here.

Real estate is a numbers game.
We don’t manufacture them.
