Officially a first time landlord and New Homeowner - in Newark NJ

[Mohamed Farih]

Hello BiggerPockets I am officially a new homeowner for a multi family home in Newark NJ.  As I am very excited for the opportunity to be a landlord I am also very nervous.  It feels like there are a lot of stuff to do and I have no idea where to start.  Does anyone have any advice on what I should focus on and things to do that I may have forgotten about.  Also, if you have any advice I would love to hear some.   

Look forward to hearing from you guys!
