Units vs Bedrooms

[Lawrence Moore]

Greetings,

Okay so I'm studying a ton over REI, am looking to start in April/May of 2017, and I have a quick question.

When someone like Brandon says "I look for $100/month cash flow per unit" what EXACTLY does that mean? I get that a 4 plex that each have 1 bedroom would equal 4 units. But what if it is a single apartment with 2 bedrooms? Is that 1 unit or 2 units? So, for a 4 plex with 8 bedooms, would that be 4 units or 8? 

Thanks.
