Month-To-Month Leased Tenants - Property Management

[Chris Reichenbach]

I just purchased my first duplex in Concord, North Carolina and plan to house hack one side and rent the other side out. One side is rented through December and the other side is on a month-to-month lease. The side I plan to live on will need renovating so the current tenant cannot stay. I was told by my agent that all I have to do is not renew the month-to-month lease and give the tenant a 30-day notice to vacate the property. Is this correct or will I have to go through an eviction or legal process to not do anything illegal? I appreciate all the help!
