Late again and today is the day to kick her out or not

[Tyler Labelle]

So this tenant is a pain in my butt as she's always weeks late.  SC has a 5 day pay or quit so i posted the letter on the 6th.  I went down there in person to address a leaking toilet and of course she promised to pay the last day "yesterday the 11th" . but here it is the 12th and no payment.  do i follow through with my threat of kicking her out?   I've never evicted a tenant as she is my first property I'm personally managing.  i feel like she just keeps pushing and pushing and if i don't back this notice up that the next one wont mean anything.
