Invisible Septic Tank

[Megan McGinty]

I’m an agent and have a listing under contract. The buyers had their general inspection last Friday and couldn’t find the septic tank anywhere. I sent our contractor out and he also couldn’t find it. The seller has only actually owned the property for like a week so they know nothing about it. The former owner gave me the number of a company who cleaned it in November but they don’t answer any calls (the buyers agent, myself and my assistant all called every hour today) and their voicemail is full. I’m at a loss of what to do. How does one find an invisible non-existent septic tank?
