Obviously this is a key research item that would warrant deep investigation in an offer type situation.

I'm being told "you're out of state",  "the condo is 'not warrantable'", "you don't have enough assets" (which didn't make sense as I own another KC property outright worth over $100k and condo is only worth about $65k, in addition 3 houses in colorado with %20 equity or more, not to mention others etc...)  

I just went through some paperwork that you would be required to sign for a conforming, conventional loan and there are some specific sections that address this area:Under the "Designation of Homestead and Non-Homestead Affidavit":Paragraph 2:  "Borrower represent and warrants that Borrower does not now and does not intend ever to reside on, use in any manner, or claim Borrower's Non-Homestead Property as a business..." 

the Rental market is very hot right now, and I would be wondering what the previous owner did in the last year to warrant the 50,000 increase in price and why are they selling after a single year? 

In situations where the payment increases this may be warranted in order to create a way to pay down accrued interest, fees and advances.  

I'm late coming to this thread and do not know the floor plan of your duplex, but have you entertained using a ductless split heat pump - one per unit, perhaps with two heads each if warranted by the size and layout.

I never say these words, because in most instances it is not warranted.

For warrants, subpoenas, and for real estate buyers.

It is a non-warrantable condo. 

Even if they are a different race, there have been a lot of red flags that warrant a rejection.
