Hypothetical question

Has anyone dealt with something like this in Tennessee? I'm not sure what my options are.

Airbnb damage claim vs security deposit. I've been dealing with this for about 16 months now and the situation isn't improving.

I have been renting for 6 years. My monthly rent is $4,412. I have a written lease.

Should I hire a lawyer for this or try to handle it myself?
