Its also unusual for all working parts to just stop working. 

I agree, it's unusual that you would have a 9" rough in if you did not change anything else in your project.

Our metro is unusually large, has two professional sports teams, and is also benefited by an eclectic variety of industry.To add to that, the affordability is extremely attractive.

Don't pass up this "opportunity".Tough love part...college and fully supporting oneself is not an easy path but it's also not unusual. 

I sent a letter about upcoming rent end of March, 1st Unit paid up right away - it was unusual because he has always late all the time.  2nd Unit - paid on time, usually pay a couple days earlier, but this time on time.3rd unit - no response - sent txt, will be a bit late, but he sent back txt, they will be alright in future as far as finance. 

And second, you won't have to deal with any wierd or unusual conditions that may be present in some of the current leases.
