I do not send out blast e-mails or anything like that.

You don't have to wait for rent in the mail, and you know immediately if rent is late and can add that on to their required payment.

They can still give you a personal or certified check by coming here in person or mailing it to you. 

I would have the 3 day notice posted (and the property manager can mail one, too, since you have plenty of time) and file the eviction paperwork the day the courts are open again. 

I'm getting many good strategies from books but they seem to be outdated, focusing on newspaper ads and mailings.

Thus, you will need some sort of registered agent for each State and mailing address.

To date we just manage our SFR portfolio using a system in Excel that I have built out for financials and other things, plus eRentpayment for rent collections, so I don't have any particular subscription software that I am using that might already provide this sort of mail service. 

I sent a 10 day letter and the tenant refused to sign the certified mail but I had it taped to the door in case this exact thing happened. 

@Colby Hager he wants to take out what is his families stuff he has been left with which is a majority of it but he also realizes some of it is junk and does not want to take.

The consensus seems the same, junk.
