Should I let septic stop me from moving forward?

[Chance Schrettenbrunner]

Hey all

Looking to buy my first deal, I have 2 options in front of me. One is a duplex, 2 bed 1 bath each side, with one side having a opportunity to convert the extra family room into a bedroom, and it is in a class A neighborhood. It will cashflow. Found out today that previous buyers pulled out due to septic being very saturated. Is that something I should run far away from? 

Other one I am looking at is a 1 bed 1 bath each side duplex, but doesn't seem to have any issues, it is in a class B neighborhood. Already has an offer, so I am thinking in this market I should maybe move on that one instead? Im not sure.. This one has a offer so I may try and get it.

Just want to know yalls thoughts! I have no experience in this kind of stuff. Thank you!
