I'd just send them with delivery confirmation with just USPS priority mail.  

This doesn't require a signature.So, what I think I'd do in your position is just send her notice with proof of delivery - I just used the USPS priority mail envelope with proof of delivery, with a copy of the new lease and a letter saying please be aware that all of the terms of the enclosed agreement will be enforced beginning thirty days from proof of delivery of this document and that you hope she will continue to be a tenant in the property (if you actually do), and then maybe include something about please let you know if there are any maintenance issues that need to be addressed.It doesn't matter if they sign for anything. 

Kill the drama and get done with it.There is no drama , she moved 40 miles away , I am not a delivery service ,  I have left her a message with no response , I will not have tenants come to my house . lease says deposit will be sent certified mail .  

Filling vacant spaces in your communities can be a huge pain!We were able to get financing through Legacy Homes, the terms are roughly 10 years with a fixed rate of 7.9% for the first 2 years then Walstreet Journals P...

I wouldn't buy existing. newark is the #1 zip code for new home deliveries under 400k this year in 2023 and is mostly being driven by DR Horton. year of year property appreciation is insane as well more than 10% on the median and average last time I checked the housing stats. if you want to build please reach out. we don't do any brokerage with existing inventory 

Possibly change the delivery of possession clause to make the estimated delivery date more flexible (if you can).Make sure that she knows you're putting 50% of the total cost to install carpet towards a tile installation instead.  

I sent her a eviction notice via certified mail, which she refused to receive (postman tried delivery few times).

You don't need a signed copy when you just give them 30 days notice of new terms.Then, send it with tracking, so you have proof of delivery. 

This 60 day notice ($250 cost) was filed (proof of delivery) to tenant and her attorney back on 07/28/2020.

And it’s always about the delivery.
