My first rental property

[Nikolai Lundbakk]

Hello! 
As that im new to the game and this is my first post on BiggerPockets i whould like to aske some questions about Rental properties.

What are you looking for in a rental? everyone is looking for ''that'' property that gives you cash-flow, but how do you know if the property have good cash-flow?

Is it a good idea starting of with a property that have  2 or more units and use one of them myself? (House hacking)

When should i ''evolve'' to buy a second property?

I know this is alot of questions at ones, but im trying to building a educational fundation for my investing future =) 
Best regards
