The closing kept being delayed and delayed and to make a long story short, after it was suppose to close and I could get no answers from Blue Gate or this agent.  

And also being next to a base Im thinking about short term renting, or Air BNB How did you finance this deal?

Long term play would be to either use it as a short term rental or 1031 exchange it after 2+ years.

The only issue with seller finance and resale is if they don't want to receive a payoff in short order, then they should include a pre-payment penalty. 

Especially if using the funds short term, there's not too much interest.

Long story short, all this means a net negative cashflow. 

Short of selling my entire portfolio, the liquid capital for the down-payment remains unattainable. 

I reached out to Ward Hanigan but that short course does not look available currently.

Here's my take on the decision:First, let’s look at the pros and cons of paying off your current short-term rental (STR):Paying Off Your STRPros:-You Eliminates your largest fixed expense (the mortgage), which increases your cash flow significantly.

A landlord looks a t how much the property will make long term.A flipper looks at how much in a short term .
