House hacking and becoming a landlord

[Frances Cue]

Hi folks, 

We are under contract and hoping to house hack a multifamily. Currently there are two tenants in placed. I'm considering not hiring a property manager since we will be living on one of the units but I'm afraid that if the tenants find out we are the owners (and we are also brand new to the city, still reading up on landlord/tenant laws for MO), that they might be able to take advantage of us. We are new to all of this and I really would appreciate any feedback or input. Do you think for newbies like us, it is safer to hire a property manager or just learn it ourselves? I am leaning more towards learning the ropes ourselves but I am also very afraid and anxious. 

Thanks!
