Rental unit wear and tear

[Benjamin Sures]

Howdy BPer's,

My wife and I just finished hosting our first tenants in our MTR.  Really nice folks, however there was some very minor areas of abuse that we noticed; missing sheet, pen stain on the comforter.  

How nit picky do y'all get with things like this?   Should I have them pay for these items?  I feel like big ticket things, say something over $200, that break are expected to be reimbursed, but want to know what you're doing?
