As Ko Kashiwagi says, we need to know more, such as rate, amortization, term.

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).

We've run about a 20% vacancy rate. 2 of our MTRs have been great, the third we sold after it wasn't generating enough inquiries over two years of effort.

I'd try to get a 6-month lease at a below-market rate to attract a tenant.

Higher turnover rate of tenant2.

Whoever they are dealing with also dropped the ball and the buyers are full of something-everything was in writing and if they signed off removing the financing clause, they are on the hook to buy. 

Rising interest rates, slim margins, and unexpected costs can kill a deal fast.

The interest rates are terrible. 

I did a quick look and violent crime rate almost double that of Illinois as a whole. 

Also be aware that cash out refinances typically have slightly higher rates than initial purchases or just rate and term refinances.
