It basically says the residence is a nuisance due to requiring an unusual amount of police or other services.

What I refer to as evergreen gas station landscaping - palms, indian hawthorne, miniature oleander, holly, asian jasmine ground cover, crushed limestone (black and it is also permeable for wet climates like mine) I have a professional landscape service neaten it up 3 times a year.

That's an unusual rental. 

A fee structure like you mention is highly unusual.

Being travertine, there is a finite amount of colors that travertine comes in, after all it's formed specifically from limestone with carbon dioxide bubbling through it from a hot spring to create it.

When I was in college many decades ago, NONE of my profs, most of whom were PhD's, had ANY real world experience in their areas of "expertise" and I know for a fact that my school was not unusual in that regard.

That being said, I am aware of the type of policy he is using (because we use some similiar programs) and it is not unusual for the banking industry.

That would be really unusual. 

Laws vary greatly from state to state, but it would be highly unusual to get reimbursed for "any rehab done" to a tax sale property if the previous owner successfully challenged the sale.  

Is this unusual or am I just overthinking the situation?
