what 's the best way to prepare as a "landlord?"/investor?

[Frankie Lotrec]

Help!! I've put an offer on my first real estate investment ever: a multifamily home.  Pending inspection, I  may have it by end of June.   I've been reading and listening to podcasts but feel like I should be "trained" in the "trade" or something....the info is all in my head but I'd love it if there were an "investor" school....I considered real estate courses but now I need to get busy cleaning it up to rent...

How can I best prep. for the job ahead of me??? any seasoned investors in the King of Prussia, PA area???:-)
