sewer disconnected from lateral

[Kieran Dowling]

I am trying to decide if i want to move forward with this house? It is a complete fixer upper. The current plumbing stack iis not connected to the man line.(see photos)

There is a floor drain on the other side of the 2x6 wall(about 10 feet). so i would just need to tie it into this

I am budgeting 20K for a brand new plumbing system for the whole house already since there is not anything in the house currently.

The basement floor is already ripped out and down to dirt. it looks like btw 2011-214 there were sewer repairs to the main and connecting to the house. (see photos)

would this be worth buying or would you pass?
