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. 

This takes away their "power" and lets them know that you aren't going to bend to their will. 

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.  

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. 

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 you are interested in doing any development, especially anything unusual like tiny houses or pocket neighborhoods that typically require re-zoning or special use permits, neighbors can get very alarmed and protest those changes to the zoning board.

Is this unusual wording?

The only real issue here is a tenant who wrote you a bad check, and is trying to get out of paying rent, even though you keep bending over backwards to fix everything.Time to grow some cojones and start eviction and let her hire an attorney.And the beautiful thing about that is - that whenever an unlawful detainer is filed - it goes on her eviction record.  

Smart business investors know that laws easily bend without breaking.
