Good luck to you, you will find with more than 50% of rent going to debt service, these are not great cash flow properties at the moment. 

Conditon of apartment is at time you take possession, so do a walkthru on that apartment within the first week or so of ownership.Ask owner to send or drop off to tenant letter of change of ownership this is usually done day of closing, and you also send or drop off letter of introduction including where and how to pay rent, and emergency service contact info. 

Is there some service that can provide contact information (name, address) of folks who are currently a 2-3 months late on their mortgage or possibly in a pre-foreclosure situation?  

We expect to be back in town soon and we'll set up another meetup!

With this latest property, I want to learn the ropes so I advertised and found a nice young married couple who can afford the rent.Move in day is tomorrow, and we set up the time for the walk-through for late-afternoon.

Is it cost effective to replace and set up individual meters?

However I believe there is an option to upgrade beyond the free service to access this feature. 

I have no affiliation to the following companies other than I have used, and continue to use their service.

Then, give them a free week of access to your list.If PropertyRadar comes to your neck of the woods I think your service might be in trouble though!

You tell them they must vacate and do no damage then you will not take legal action against them (I call this the easy option) and you will then either allow them to use their deposit against what they owe you and/or set up a "promissory note" payment plan - which is enforceable by law.
