The Landlord Operating System

You bought one rental. Then a second. Now you have four — or

eleven — and your "system" is three spreadsheets and a paper

folder you keep meaning to organize.

Lanis OS ends that. 19 tabs. One workbook. Built for landlords

with 3 to 15 units who run their portfolio like a business.
