Tenant repeatedly late on rent

[Sagar Mylab]

Hi BP, 

I have a tenant with a 2 yr lease that started the beginning of this year.  She has already been late on rent 3 times so far.   I've been sending her notices of late rent every time and this has continued to happen - even this month.  In this last notice, I notified her that her lease would be terminated & that I'd be sending her a 'move-out notice' if the rent is not paid by today.  I am relatively new to these types of issues since all my previous tenants paid the rent on time so I didn't have to deal with this till now.   

I'm sure this has happened to some of yall in this forum so I'd like to know what you did in such a scenario & any recommendations on what I can do if she continues to be delinquent & does not move out?   I have a mortgage to pay so I'd really like her to move out ASAP so I can get it back on the market for other tenants.
