I mainly mail to 4 units and less.

You need to persuade people that selling to you is a better option than calling any of the other numerous solicitations they get in the mail every week or listing it with an RE agent. 

What I mean by that is they lure you in with the free trial,  however, the free trial doesn’t give you near enough time to set up a website squeeze page your profile couple of direct mail mailers and any other marketing tool there is on the Automator.  

A Notice of Updating Mailing Address for tenants updating the tenant’s mailing address was filed in the prior eviction.13.

However, if you really want to be defensive, there's Box for cloud storage, and Proton Mail for email, both of which use "zero knowledge" storage.

I still like direct mail.  

.: The post office will typically rekey the mail box when a new tenant is placed.

Sorry I know this one is going to be painful for many rookie investors just getting started who want to live on the beach with their mail order cash, but this is not they way investing works. 

I e-mailed the city council people and the response I got was basically "We're not allowing more than 250 STR's in our city so get in line".

Direct Mail Campaigns: Think about sending postcards or letters to homeowners in specific neighborhoods, especially those who might be facing financial challenges or have inherited properties.
