Yes, there's a 5 day grace period here in WA as well, I even got a lease amendment about it, but I worry less about lapsing for 5 days and more about situation where I get into a car accident and am in a hospital for a week. The lease agreement language is very harsh - if you miss a payment, and lease office can decide to be shitty, they can "accelerate" the entire lease and make me pay 6+ months at once. I'd rather keep that month prepaid so there's less chance of this happening.
