How to avoid vacancy gaps in midterm rentals?

[Sean D. Thomason]

I have a midterm furnished townhouse in Chattanooga, TN. I have my rental listed on airbnb, furnish finders and zillow. My issue is renting out the townhouse and getting requests that cause odd gaps in between my bookings such as 3 and 1/2 weeks. There is a STR moratorium currently in effect so I cannot fill in the gaps with short stays. I have a couple other rentals that are long term so I have not run into this issue. Any advise on how to run a midterm rental without gaps would be greatly appreciated.
