Something like a small unpaid cell phone bill or medical bill.

Sure, we get phone calls ate 3 in the morning because a kitchen light blew out, but that is very rare and even though I get a little angry it is still a nice feeling to know that my tenants have the ability to resolve problems when they get no satisfaction from managers.My wife and I carry separate cell phones for our tenants to call us.To manage our properties, our lease agreement is 24 pages that consists of all our rent payment and eviction policies.

They were taken with a cell phone, not by a professional photographer, and not using fusion photography which is standard in our market.

We purchased a cell phone based wireless alarm system that we place in our units when vacant.

Google voice is free and will ring to your cell phone

the folks I know that have the stomach for this type of investing have their own custom scoring system I have often enquired how they do it .. since 95% of the tenants will be below 600 ficoWhat they look for is habitual non payment of little things like cell phone and direct TV etc etc.what they over look and don't count is medical and eviction is out.you just need to pick the best you can... and maybe your tenant base is not that bad but in C to D in the mid west this is your tenant base. 

Cell phone, car, etc.

Yes I know that they could be living here with their cell phone .  

Make sure all contractors that you work with have reliable vehicles and cell phones. 

Also you dont have to worry about paying for it ITS FREE and you can change your cell phone carrier and not have to print out new cards.
