One for her to sign (if you're hand delivering) that acknowledges the receipt of the letter, and one for her to keep a copy of.Source: I'm a MA landlord and have gone through this process before.

@Brian Cain buying as-is just means he won’t make any repairs and you acknowledge this.

Account Closed Kwan, thank you for calling and apologizing and acknowledging that you made a mistake. 

The Judge acknowledged this history and stated that she had not yet signed that Order.

I did want to acknowledge Nicholas and give credit where credit is due.

They're acknowledging they haven't seen it and accept the unit in its current condition

I want to be optimistic, but we're not out of it yet and it's hard to not acknowledge the uncertainty. 

Yes, it would be better if she would clean the place out and do a walk through inspection with you like she's supposed to (hopefully per your lease) but it doesn't sound like she's going to go along with the program.If she is willing to acknowledge that her tenancy is over, preferably in writing, and all you have to do is move her belongings for her that gets you to your goal of re-renting faster.

You gotta acknowledge there is a difference between knowing that REI can replace his W2 AND knowing how many assets it will take to get there (also how much it will cost to acquire each asset and how much time it will take to acquire 1 asset). 

Just show them that you're working on the issue and responsive, the greatest trick I've had with tenants is to just acknowledge you're listening.
