Sewer Line Help Please

[Phil Leighton]

So I was about to close and the buyer backed out last minute as there were roots discovered in the sewer line which I understand is a common problem.  The sewer pipe works fine, haven't had any issues.  I was quoted 7k to get it lined and 16k to get it replaced.   At this point I'd rather just take it off the list price but I'm hesitant to take 7k off as the pipe is in working order.  

Does anyone have any experience with something like this?   Advice/thoughts/suggestions?  Thanks.
