Equity tracking for co-owned real estate
Two friends buy a duplex. One puts down 60%, the other 40%. They split the mortgage 50/50. One year in, one of them pays for a $14k roof. Six months later, the other refinances. Then someone wants out.
What does each person actually own at that moment?
If you've been near a co-ownership arrangement, you know the answer: nobody knows. There's a Google Sheet that worked for a year and then broke. There's a memory of a verbal agreement. There's a slow argument that ends a friendship.
I built Real Amigos to fix this. It's an equity tracking app for co-owned real estate. Every contribution — down payment, mortgage payment, capital improvement — gets logged with a timestamp. Each owner's share evolves automatically in real time. The math runs underneath, so you don't have to.
What it actually does:
Tracks dual contributions (the part that builds equity vs. the part that's just shared expenses)
- Handles principal payments scaled to base equity appreciation, so refinances and mid-stream payoffs don't break the ledger
- Logs sweat equity transfers between owners
- Maintains a contemporaneous audit trail — when the inevitable life event hits (refinance, buyout, sale, divorce, inheritance), the equity story is already written
Where I am:
Pre-launch. The equity engine is the hard part — I've been pressure-testing the math for months across edge cases (correction factors, depreciation curves, sweat equity mechanics). The app works. I'm now in a 30-day window of: finish polish, line up the first 10 properties, ship.
What I'd love feedback on:
If you've ever co-owned anything (property, business, equipment, anything with shared equity), what did you wish the tracking tool did?
- If you're a builder in PropTech / FinTech, what's your read on the wedge here? Is "co-ownership math" a big enough problem to be a standalone product?
- If you know a couple, family, or friend group buying property together right now — I'd love an intro.
