Need advice - tenant gave me 15 day notice

[Acie Martinez]

I have tenant for 6 years with an annual lease renewal. The lease states that owner and leasee must provide a sixty day notice.

About 60 days before the lease expires, I spoke to tenant and the tenant wanted to renew but didn’t know if her son’s girlfriend will move in or not.  

So on Jan 15, I spoke to the tenant about who to include in the lease when the tenant said that she was leaving at end of January in 15/16 days.

So my question is what are my rights?  Can I ask for 1/2 months rent? Or more?

Any guidance would be appreciated.

thanks
