What neighborhood is the duplex located in? 

This decision turned out to be a tough learning experience due to the location and condition of the property.

I would rent or sell that condo and buy a duplex in a class A or B location in KC.

Are you located in FL?

look for land with owner financing And I am sure you know this but location and safety will be paramount in the Jackson market there are simply areas the crime is far to high for this to be successful..

Additionally, in my market, a lot of these properties are located in areas where price-to-rent ratios are extremely favorable.

I see 3-5 as a fad.Fractional ownership - way to much overhead for these to be profitable. think "timeshare".STR in non traditional markets - running a STR is a business and real estate, boils down to location location location - who would want to go to a conference and stay in a STR vs. the hotel where the conference is at, most businesses pay for this I do not see why.Mixed use with green - this has been going on for years- it will continue but it is also more expensive to build - which means higher costs to use.Not trying to be debbie downer, I have seen these attempted to be done in the past and they really have not been successful.I do really like the BTR model though as I continue to see that as a very good option in the future. 

Your niche depends on location and amenities you offer.

It was built in the 2010s and located in an established neighborhood with convenient access to schools, amenities, and major transportation routes.

@Huggy Ford, I would be interested in running an analysis of need to know what's in the highest demand for that location.
