What's best way to search for Multi-Unit property for investing?

I'm looking to find my 1st 2-4plex multi-unit property for house hacking & investing and am curious (from expert opinion) what is the best way to find one? ..A realtor? Refin, Trulia, Zillow, etc.?

Also, how to valuate if it's a good investment? Is there a certain calculator tool or spreadsheet you use to run specific criteria to assess best cashflow?

And.. Property management? How to find a good property manager after? And how to find & properly screened tenants...? Craigslist??

Thanks!
