Timeline for notices after nonpayment of rent - Virginia

[Matt B.]

In Virginia, we have a 5 day grace period after rent is due.  So assuming rent is due on the 1st, rent is considered late (with a late fee) on the 6th.  

What timeline do you fellow Virginia BPers follow as far as notices being sent, court filings, etc??  I'm looking for a hard timeline that says for example:  Day 1-rent due.  Day 6- notice of nonpayment of rent sent out, day 10- blah blah.    And the timeline that you use, do you tell the tenant so they know exactly when those dates are so there's no question?
