The free and clear property is out of harm's way. 

@Timothy Eaton Starting off your business by breaking your word to a business partner may harm you more in the long run than honoring your word and making less.

For you, it is now apparent that you only intend to argue a point which has no substance.

I was going to offer to have the testing done but tell the tenant that if the results show no harmful mold, the cost would come out of her security deposit.

While you'll get only part of the sales that have taken place, you'll still get a certain amount of data, which could appear to be useful at first glance.However, when seriously thinking about it, I can't see how it'd be useful and I'm even thinking it could potentially be harmful.

No harm at all, and I can totally respect that.If there's no instructions, and I'm placing a bid I expect them to fully see it.

I try to be cordial and brief, but his issues have become increasingly bothersome.He now believes he is the victim of a serious crime, often calling to tell me the police are coming over (which they never do), or asking if I see a specific car on the street because he fears they are there to harm him.

You should certainly start the process earlier than maturity, especially at the very least within a couple months of the maturity date - there can always be things that cause delays and pushes and even missing the maturity date by a couple weeks can have harmful consequences (since it will technically be a default / missed payment even if the lender is OK with it).Also, commercial loans even with the strictest prepayment protections / lockout periods will almost always have at least a 3-month open period prior to the Maturity Date
