Chattanooga TN eviction

[Brian Palmer]

I bought a duplex two months ago that already had tenants in both sides. Unfortunately one side was late on the rent the first month, and has not paid so far this month. The lease states that they waive the right of notice in bold letters per state law.So since they waive the right do I still have give them 14 days for them to pay or can I go ahead and file for detainer warrant now ? The lease also states habitual late payments are grounds for termination. Does two month meet the criteria for habitual ? Thanks for your input
