The heart of Back40: run a wholesale / flip / JV / BRRRR deal and land on your number.
Is this the wholesale calculator? Wholesaling is the flagship mode, and this base tier also includes flip, JV, BRRRR, and amortization.
How do I start? Create an account, choose a plan, then paste a listing into the calculator.
Comparable to: a plug-in underwriting spreadsheet, but it does the ARV math and Max-Offer calc for you as you type.
Best for: flippers and wholesalers who mainly need offer math without a deal feed or CRM.
Bigger-fish underwriting: commercial and ground-up development modes.
Do I need this for single-family flips? No — that's covered by core. This is for developers and commercial buyers.
Comparable to: commercial real-estate underwriting tools (ARGUS-style but web-based).
Best for: builders, ground-up developers, and multifamily / self-storage buyers.
A live feed of self-storage and land deals so you're not hunting listings by hand.
Does it pull leads automatically? It's a curated live feed; you review and log the deals you care about.
Comparable to: a deal-finding service (Off Market, PropStream-style) built into the same app.
Best for: people who want deal volume without a separate sourcing subscription.
Keep every deal and the people behind it in one place — with follow-ups on autopilot.
What's it comparable to? A lightweight CRM (PipeDrive / HubSpot-style) purpose-built for deals, without the setup.
Do I need this on day one? No — add it when you've got enough deals to track.
Best for: agents and wholesalers managing multiple deals and contacts.
Paste a listing or comps and let AI fill your worksheet instead of typing.
How does it work? You paste raw text from an MLS listing; AI extracts price, lot, address, and pulls comps into the ARV.
Do I have to use it? No — you can always type values manually. This just saves time.
Best for: anyone who hates data entry.
Push your saved deals straight into Airtable so they live alongside your other ops data.
Who needs this? Teams already running Airtable as their system of record.
Can I skip it? Yes — deals save inside Back40 fine without it.
Share your workspace with partners and staff.
Best for: small teams that want everyone on the same deals.
