Converting old Multi family to Individual Utilities

[Beau Fugitt]

I am looking at an older 6-plex to flip or BRRRR with shared utilities (master meter). I recently heard on BP podcast, with Bryce Stewart, you can convert a property like this so tenants are charged for their individual usage. I have no idea what this requires or how much it would cost. Can anyone with some knowledge about this give me the run down this type of project? (I know I can ask an electrician/HVAC professional but I figured I could get some friendly advice here first).
