Good resource for landlord/tenant laws for TN?

[Alicia Gates]

We're getting our first SFH under contract, and I just got the lease for the current tenant - it expired in 2017. In addition to everything else I need (like lease agreements, info on evictions, etc.), my main concern right now is: does this mean it's defaulted to a Month-to-Month lease?

Not sure exactly where I should be looking to answer these questions.  Thanks!
