Could a service truly warrant a 10x jump in price?

Contractor responded they would be unable to warrant work on the unit, since they didn't buy it.  

Is he warranting his work?

I have about 4 areas I am researching and if I can get a hint of reliable intel to warrant a visit, I am not above that.

Your question seems complex enough to warrant a preliminary discussion with a legal professional.

Your situation is complex enough to warrant hiring professionals to help you.

Doesn't seem to warrant so much worry. 

@Nick Dillaha Its fine as long as its not non-warrantable. 

You can market it as you want to get the property sold (whether it is to you or to a different buyer) but if they find out you have your license after the fact, that may warrant a consumer complaint. 

I don’t know about New York but most states including North Carolina  have enacted an expedited eviction procedure for 10 tenants violating drug laws so just do your routine property inspection and leave a small amount of drugs in a closet ,  then call the police for search warrant which will remove the tenant to jail  The unconstitutional CDC addiction ban does not apply to evictions for anything other than nonpayment of rent
