If you own 1 to 5 rental units, you’ve probably lived this: rent hits your bank account and you’re not totally sure which tenant it was for. A repair bill comes in and you can’t say off the top of your head whether that property is even worth keeping. Tax season arrives and you’re digging through a year of bank statements trying to remember what a $340 charge in June was for.

Property-management software like Buildium or AppFolio wasn’t built for you — it’s built for people managing dozens of units, with tenant portals, maintenance ticketing, and a monthly bill to match. A generic spreadsheet from Etsy just gives you rows and columns, not answers.

Rentwise sits in the middle, a single Google Sheets/Excel file that answers the exact questions a small landlord actually has.

Rent Tracker: who’s paid, who’s late, who’s still owed, color-coded at a glance.
Cash Flow: real cash position, reconciled against your bank balance every month.
Property Profit: what did this specific property actually make this year?
Month-End Review: a 15-minute monthly checklist that catches mistakes before tax time.
Tax Summary: your year organized into Schedule E categories, ready for your accountant.
Dashboard: one screen, one month, every number you need.

No subscription. No login. No learning curve.

Built for landlords who want to run their rentals like a business, without turning into a bookkeeper to do it.
