Every great rental starts with a confident yes. greenLight turns a price, a loan, and a rent into one clear score, so you can move fast on the right deals and walk away from the wrong ones.
Most investors don't lose money on bad luck. They lose it on a number they guessed, a spreadsheet they didn't fully trust, or a deal they rushed because it felt right.
We believe every investor deserves the same clarity the pros have, without learning a wall of formulas first. So we built the tool we wished existed: honest math, a clear verdict, and a design you'll actually enjoy opening.
