So B2C is out, but perhaps B2B might be an option (e.g providing a streamlined solution for all of the major mortgage servicing companies for collection of payments.

Your opportunity is also what's difficult, having virtually unlimited options :)  

After buying this house, I partnered with others to invest in a duplex in the Wichita area.At the moment, I’m living in Tennessee, and I’m weighing two options: either selling my house and using the proceeds to buy a duplex in Overland Park or Wichita with my partners, or keeping the house for another 3 years, transferring it to our LLC, and renting out the entire property to maximize its rental potential ( $1400-$1600 ) I currently owe $200k on the property with a 6.5% interest rate, and my monthly payment is between ($1,700-$1800).

I have a potential private lender, but I need to determine if this is a viable investment opportunity and explore the best financing options 

And you are continuing to invest in real estate a 1031 is a good option to explore. 

The last month I have been exploring house hacking options as an easy option.

Good bad idea before I depart - have you considered an owner occupied option?

However, as Zane mentioned in his response, another option is to consult with a lawyer who specializes in appealing property taxes.

Even then, all of my booking.com clients are American I offer a 25% discount 0-3 days out. add a 15% fee which essentially covers your commission. set up with one hour to cancel, flexible / strict option but no refund 60 days out or later. sync it with Airbnb and or the other ones you are doing.

If you think hiring a CPA to discuss your plan, how you can do it, and all the roads you can take with that, than that is the best option for you!
