Managing Duplexes and/or Triplexes

[Jose A. Gonzalez]

Hello everyone! I hope everyone’s doing well. My newbie question is the following:

Let’s say you own a triplex, you live in a unit and rent the other two out. Are you (the landlord) paying for electricity, water, WiFi, and such for every unit? Or do you have a contract that specifies what the tenant pays and what you provide? Is there a way to track how much each unit consumes each month? Thanks in advance!
