Outfit the space as turnkey for an appropriate business (smoothie shop, dry cleaning substation, etc.) and sell the “business” with a small down payment, receiving a monthly payment for the business payoff + rent/3.

I would be focusing on cleaning up bookkeeping, communication portal with client, vendor list management, payment processing, etc. 

When you look at the percentage of "clean" energy produced by each state, Kentucky is ranked 37 out of 50.

Hopefully they leave the place in good shape and clean so you can put it back on the market

Clear up the myths, clean up the mythos, and truly get to nuts and bolts of investing.

I'd also have money held back at closing (a significant sum of money) that they do not get unless they are out within the 30 days (or whatever you agree to-do whatever you need to have them treated as a short term tenant) and leave the place clean and in good condition (ie same or better than when you viewed it).

Quote from @Branden Rivero: The issue I see is the building is close to 100 years old and with a $500 hoa it's not an easy sale for an investor Yes, thats true however all expenses the past year increase insurance, sewer, trash, electric and cleaning service.

If they choose to leave, then I would give them no more than 60 days to vacate, clean the place up, and rent it for market rate.

The harsh truth is that you aren't looking out for your aunt.

The attic has to be cleaned as well.
