Tenant Didn't Give 30 Day Notice - Is Lease End Date Still Valid?

[Wade Penner]

I have a 3BD with great tenants that have lived there for the last three years.  They wanted to stay past the original lease-end date of 6/30/24 through end of summer, so I told them they could go month-to-month through end of August.  However, I got a call from them yesterday saying that they had some things fall through and need to stick with the original 6/30 lease-end date.

I now need to do a quick turnaround on renting the place out.  I use Oregon's multi-family NW forms, but it's unclear to me exactly how to proceed.  Are they on the hook for 30 days of rent starting from when they called me, or since their lease ends in two days are they good to go without any additional fees?  If they are on the hook for any fees then would I just deduct that out of their security deposit?

Thanks!
