Total newbie with familiar starter questions

[John Heck]

hello there, just wondering if anyone would offer advice on some questions.  I am eager to try a real estate investment and actually found a possible rehab very close to my home...Mls listing 6394374

I checked out the outside property today and I'm going to see the inside tomorrow. With my neighbor who is a realtor.  Looks rough and looks vandalized (central act unit busted open from copper bandits, front door busted open but hinge lock keeps it "shut")

Zillow states the listing realtor will only represent the seller so that means I will need a realtor on my end right?  It's listed at $66,600 but I don't think that's realistic so where does that number come from?  If this were to proceed in any way would it be just like buying my current home...get approved for a mortgage...make offer...have settlement...fix up..sell for profit...pay off mortgage...hopefully have some money left?  Any advise would be helpful!  Thanks!
