A handful of other things have happened to, which completely put a bad taste in my mouth (IE: she asked if her niece and her nieces baby could move in for a month and I said no - she didn't listen and they moved in - technically she broke her lease right then and there but I let it slide knowing her lease was going to expire) (she thought another tenant knocked her garbage can and grill over -- when it was just the wind).

This is because the area has very high rents, and with travel nurses I have to pay for all utilities, including heat in a Northern climate, internet, garbage, lawn care, and snow removal.

Not all my calls were for drugs...some were for fights, throwing garbage in my yard, noise complaints, etc.

Yes there are garbage coaches out there. 

Or do I risk it looking like garbage and having to buy all new countertops?

Garbage.

Complaints like noise complaints, smoking in the building, and leaving garbage out in the open.

I've had units with garbage disposals.
