Pay or Vacate Notice

[Evan Hauler]

Hello Everyone! 

My first tenant has her first full month starting in February, she has let me know that she won't pay until the 2nd, the lease has it is due the 1st with a grace period until the 5th.  I said that that this month is ok but rent is due on the 1st going foward. Would I be able to issue a pay or vacate if she pays on the 2nd again? 

How would you guys handle it? 

Thank you all very much!
