Would you buy a MultiFamily with a Septic Tank

[Lamont Marable]

A wholesaler disclosed this property in Ohio to me and here's what he said: "All I really have on it right now is the address is 7XXX ---- avenue. Rehab will be close to $60k ish, because it has a septic tank that needs to be hooked up to sewer. Half the units have been updated. It’s located in Elyria township. Brings in $5100 gross, just needs a great rehab. I only have like 6 pictures will get more this weekend"

My concern is the septic tank which is something that brings me nightmares.  How would you approach this deal with limited detail?
