30 day notice to vacate or pay or quit?

I have a tenant in a property I recently bought and she owes me for July rent.  She told me she will have the rent tomorrow at 7pm, but she told me this before.

She is on a month to month lease and I think I want her out.

Should I just give her the 30 notice to vacate, or should I post the pay or quit notice first? Assuming she doesn't pay tomorrow.

If I just give her the 30 day notice to vacate, she probably wont give me the rent anyway, but I could go to the court and show the proper notice to the judge to grant the eviction. Would this be faster than the pay or quit route

 Thanks.
