Have to go through my first potential eviction. Help?

[Brandon Hurlburt]

So we just bought a triplex. It looked like it was fully leased out, so I felt pretty good about it. One person was only there for 6 months, but the owner said he really liked it there and wanted to stay. After buying it I found out that he's been late on is rent almost every month. Lol. So I talked to him yesterday, mainly to see if that would still be a problem. He said he wants to move out (6 months left on lease yet) So I told him I would serve him a 14 day notice to vacate, and if he was out by then, I wouldn't file an eviction and we could call it a wash.

I'm not concerned about missing 1 months rent, especially since the kid looked like a deadbeat anyways. I looked him up on FB and apparently he works at "Real n**** s***" and went to school at the "University of Marijuana".

What happens if on the 15th day I go there and they're still there? Can I file am eviction that same day? I can't change the locks while theyre at work, can I? Lol. I figured I could just play stupid and say I thought they moved out but never got their key back so I changed the lock. Then say I forgot where the key is on the new lock. Haha.
