Just do your business the right way and be above reproach so that when you get accused, no one can prove their false accusations.

I wasn't making any accusations.

That is a situation whereas; it’s best done at time of incident so that there are no accusations just facts.

Also, it could be possible that you could be accused of "interfering with a contract".

While I am not accusing your agent of doing this nor would I think it is why it took so long for an offer to get a seller( FYI, while I don't know of any specific analysis, I would guess that 80% or more of Agents violate it unintentionally.)Again, I don't think this was the reason for your predicament, I would likely chalk it up to someone who is inexperienced or more of an AINO( job requires license " Agent In Name Only") depending on the compensation level of the agent as an office manager, they might not be as interested as your typical agent.

@Thomas Robb     I think some of the things you are looking for have already been drafted up for you, but I'll make a list of some that come to mind in order.Before you start showing, make yourself a one page 'Tenant/Applicant Acceptance Standards' list and type out your acceptance brackets i.e. income 2-3x's rent, minimum credit score 450, etc.... etc... and absolute denial (i.e. no previous or current sex offenders, etc.) and get it notarized at your local credit union (or you lawyer) make sure you consult fair housing standard and then have it dated and then make sure you apply those standards to all applicants - Important if for example, anyone tries to later accuse you of discrimination for denying them for having a low credit score or getting denied because they were a felon previously (just an example) , you can then clearly show that your standards where well established long before they ever came into the picture as the notary shows - won't protect you for all, but better than nothing.

@Arthur BanksundefinedMake sure you have a written set of criteria when processing applicants so you can stay out of the soup if a tenant ever tries to accuse you of violating Fair Housing laws.  

When I went into the tenant's unit who was accused of stealing electricity (to do unrelated work), I saw the extension cord running towards the common area hallway where they would be stealing the electricity.  

How can I obtain an official death record to confirm that there was indeed the death inside the unit in order for me to inform the new tenant and accused the seller?

Nancy Roth, I have been pointing out issues that are precieved or might be assumed, not accusing you of ill intent.
