Kick roommates out?

Is it possible to kick room mates out in Sims 4?

Yeah, kill them.

Hahahah, well what's the quickest way to do that?

If you go to options, 'manage worlds'. Click on the household you want to edit, a little symbol next to it should appear as three dots '...', click that and then choose manage household. Click the household and then choose 'transfer sims between households'. You can then click create new household at the top and move them out. You do not have to move them onto a house they can be saved as 'unplayed'.

Hope this helps, it's the only way I know how! Wish there were an easier way!

Use house management.
Or lock them in a room and delete the door.
