I have a tenant who is already late on his payments but he was smoking in the property and caused a fire.

If you are not licensed, then why would you sign the lease and open yourself up for any lawsuit the tenant may file or cause?

This miscommunication almost always causes problems and escalating emotions. 

My understanding is that you cannot get a tenant out "just cause" you want to move into it.

The tenants are responsible for anything that happens within their leased space regardless of the cause. 

However, my timeline is flexible, so I could end up staying for a shorter or longer period depending on future plans.In my research, I’ve noticed that many condos in Buckhead come with renter restrictions, which is causing me to reconsider this approach.

Have you ever had a pet cause more damage than the fees you've collected?

The ground is now about 4-5 inches below the foundation line and it's also causing issues with my neighbor's adjacent yard.

that caused me to turn to music, I haven't listened to music while working out or on a walk or working in the yard for years, its always been podcast time, in the interest of maximum efficiency.  

Its caused him to go in to extreme debt and he just needs to get this handled.
