Given the huge number of individual inventory items in a convenience store and liquor store, selectively doing this would presumably be pretty hard for me to track down. 

Are you more comfortable working with a team or an individual?

We are based in Wood River, IL and have a 4-plex and 7-plex that aren't individually metered and don't have that problem. 

It needs work that she can't afford to put into it and most likely wouldn't sell to a regular individual.

Talk to your insurance agent, but the agent I picked has over 25 rental properties and all are protected under individual policies + an umbrella.

Another great resource is everyone individual websites:blog located on the signature line.

I will separate all electrical and plumbing, electrical will be individually metered and plumbing sub-metered.

Our lease stipulates that if anyone not on the lease agreement who is staying more than 7 days in a month we are to be notified of this individual and who allow us to do a background check.I confronted the tenant about this boyfriend and that he has been there more than 7 days (eyewitness from neighbor) and that we were concerned. 

Depending on the individual and company adjusting the loss, that could end up being very little.  

Like @Dion DePaoli said you should be able to get a credit report from the seller of the note, assuming it's not an individual investor who isn't set up to pull credit reports and has held on to the note for some time now (meaning any credit report they've received before they owned the note would be outdated).If your only concern though is the status of the first, then ask the seller who the first is held by.
