Is it best to just throw cash flow at the loan untill the principal is paid off (current cash flow between the two properties after interest and all expenses are paid plus vacancy rate = about $250 left monthly) refinance at renewal to pay it back in full? 

Early in my career I worked on cattle ranches, then started doing farm and ranch loans for seven years, and now have been doing hard money lending and other real estate investing.

Quote from @Burke Atkerson: With over a decade of real estate investing experience and over 100 flips, I now provide private money & hard money loans.

@Robert EllisAre you leveraging construction-to-permanent loans or private funding?

You can get a normal owner occupied home loan to do this.

If that's what you're really after I would start with the basics of what kind of bank loans either residential or commercial are available to you - not saying this is the best option, but it's a good place to start.

If it's on your credit, you are on the hook for it.However, it shouldn't effect the loan process too much, a simple Letter Of Explanation should be able to get the job done with the correct investor. 

I had a call with a loan officer yesterday and I am very intrigued, but haven't heard much in recent discussions for this product or found anything in the search bar for this bank. 

Im looking to try and either get a duplex or a single family with a FHA loan.
