Notice to vacate

[Michelle Marty]

I have a tenant nearing the end of their lease. The last time I spoke with them they stated they would be moving out. Today they sent an email saying they were staying. The problem is I already have a new tenant lined up. The new tenant is paying more in rent and I have had a few issues with the previous tenant, nothing I could really document though. They would just complain all of the time. They call me to come and replace light bulbs, fuses if something makes a noise or looks crooked they call and demand I come. I always do and 90% of the time it's nothing. I send a handy man there at lease once a month. It isn't because the house is falling apart. It was built in 2007. They are just complainers and are never happy. They've really just been a big pain and I was happy to hear they were leaving. I emailed back and said I was sorry but already had a new tenant. They responded that I didn't give them proper notice to vacate. How in the world do I handle this?
