Raw Sewage Backup in Crawlspace

[Steven Cherry]

Hi all!  I am in contract on my first multifamily property.  During inspections,  a raw sewage backup was discovered in the crawlspace. We required the owner to get the issue professionally corrected and get back to us with the root cause and receipts for the fix.  The owner says that it was due to a broken septic pipe and it is all now fixed.  However, he has not provided any receipts to this point.  It's been dragging for some time and I would like to proceed with the crawlspace inspection and the septic inspection.  Since the raw sewage was a health hazard, I wanted to be sure there are no issues after I purchase.  I do not want to lose the deal.  Any suggestions?  Would you proceed with inspections anyway or wait until they provide receipts/documentation of the cleanup?
