Lease ending March 31st. How to get tenants out?

[Ida Powers]

I have inherited tenants that have a lease ending at the end of this month. I want to get them out so I can update the unit. I have given them no indication that I will be renewing their lease and they know we have been working on the other unit (duplex). How do you typically handle telling them that they need to move out at end of lease? There is a language barrier so a simple conversation is very difficult. Lease does not have any end of lease language. Any tips would be appreciated!
