You haven't revealed anything that would alarm a seller at this point.Get a redacted set of financials to share with qualified individuals.Have an NDA ready to go.No showings or deep due diligence without an LOI and earnest.Locate COIs (centers of influence) rather than marketing to the masses. 

What we do know now:Tenant has changed locks.House has some issue with sewer gas coming up into the home, which may have happened from property managers husband plumber fixing pipes as we did a huge repair and it started around then.Tenant is now reducing rent by 1/3 legal in New Mexico because of sewer gas.People who we have tried to look at the property to fix the problem have refused to work there because the tenant is freaking them out and talking about lawsuits and looks like she is on drugs.People now keep mentioning drugs to us, but when we spoke to the officials they had no records of tenant other than a fresh eviction before our house. 

The two septic tanks are about as old as the property (25-30 years).We spent a good amount of time talking about her garden and the trees she planted and looking for fresh chicken eggs (we found 4 eggs).
