If it were me, I would pay it off asap so I didn't have this hanging over my head. 

Only way your going to pull that off is with a partner or with private money that YOU line up (not a mortgage broker).I have bought houses with the vendor carrying back all of their equity - so it is possible, but I was working with motivated vendors (key word here), and without an agent getting in the way.

I am looking at an off market deal to help a neighbor and make a long term investment.

Don’t go out of your way to put yourself on a REPS treadmill you can never get off unless you fully commit to the decades or lifetime of defer defer defer and never realize the income.

I am looking to find more off market homes in the surrounding Rural Markets of Ft Worth for flipping and/or keeping for rentals 

I could be off here, but my understanding is that if you are already in the business, you have a precedent set and can depreciate furnishings as you scale your portfolio. 

That means you can never take cash out again unless you pay it off.

I did hear on one of the videos I watched to try to purchase off market. 

I would like to know by what process can I get a Special Warranty Title converted to a General Warranty title, if I pay off the liens or second mortgages ?
