While the driveway space isn't covered, it's still closer to the front door than the street and the tenant never has to worry that they'll have to park down the street bc there's an unusual event going on in the the neighborhood. 

Professionals who speed aren't that unusual ha ha.  

Most every lease includes fees for late payments. 18% per year is unusually high and odd in general.

Yeah it burn's to hit a good tenant with a late fee when they are down on their luck, but if you bend one rule, I suppose your inclined to bend more on a per situation basis which I do not want to get into that's for sure. 

And, this is not unusual.  

And this is not a particularly unusual story.Sure, there are good managers out there, but if you look at what is "standard" in the industry, and what they consider "standard" to have in their contracts, I think it's just .... wrong.  

They then started receiving notice of (IMO) unusual feedback - that the security deposit would not be refunded in full because there was dust on top of the washer - stuff that just doesn't sound legit.  

If so, having been in their shoes, it is not trivial to open a bank account until you get a SS#, etc which takes a few weeks or months after arriving.In some countries it is not unusual to pay at least a few months upfront. 

And I really don't think you should go after this tenant any more than trying to get the insurance to pay for damage.It's not unusual for water to end up outside of a bathtub/shower that uses a shower curtain. 

This definitely helps, but you'll still get hopeful people who will lie, and hope they can charm you out of your criteria.The good news is, in your market, you won't have to bend your criteria.
