Eviction Strategy Question

[Alan Diamond]

We have just acquired a new property and we are having issues with one tenant.  She has a spotty payment history and has already broken a deal we stuck last Friday to pay on Monday.  Rent was due on the 1st and here we are on the 17th.  She has a month to month lease, we are going to give her a written demand for payment on Monday.  Which is the safer path, should we pursue eviction or just try a 30 day notice since she is month to month?
