Best Place to Find Multi Family Properties

[Benoit Roddier]

Hello everyone. I recently joined BiggerPockets I am an international student from France currently studying at the University of Oklahoma. I have one more semester left and I am planning on house hacking a four-plex right after getting my degree. I am not sure where I'll be working after college but I wanted to get comfortable with analyzing properties so I wanted to get some advice from you all. 

What is the best search-engine for multi families properties? Do you personally look at more than one search engine? What exactly are you looking for to determine if an area on the rise or decline? 

Thank you for your time. I'm looking forward to interacting with you all.
