Red flag duplex. Too cheap?

[Steven Shotts]

I have found an opportunity but I need a good inspector in my area.  It's odd.  It's a duplex next to a community college and all the other houses next to it are 100,000+, but this place is only $50,000. It's a 6br 4ba duplex.  It does say it needs some tlc. built in '78.  Pics look fine, but inside is dated.  I'll check it myself before going under contract. One renter could cover the mortgage.
