It is required prior to evicting, make sure you read the requirements for the 3 day notice because one slip up on it and you may end up having to start the process over again (little things like not having your phone number, not having or an address within the county to mail rent to, including other fees other than rent in the amount due) or counting days that do not qualify in the 3 days such as the day you post it, weekends, or court holidays)They were able to push the last landlord around, don't let them do the same to you. 

@Ryan Murdock  Watched Podcast #234 you were on and I think you`ve fully addressed this topic here.

Were the addresses listed on them identical or close to it?  

Most states have laws that require the addresses be put on the deed. 

Find out the owner address, and send them a letter indicating you want to buy their property.

There are several states that have addressed the assignment game, and FL has as well.

Assessors send taxes to the property's mailing address.

FL already addressed it.

Certainly, there is some basis for doing so because many states have not even addressed the issue at all, thus allowing many to go unchallenged in their operations - so far.I simply wanted to present information to people because I believe - which I was clear about - that RTO and LTO are a very shaky business model that could have long-term consequences for those so engaged, as a counterpoint to all of those gurus who post here espousing those methods to help promote their get rich quick schemes. 

I think that if I could direct people I'm marketing to my email, my phone, and a web address, it would give them options to contacting me and maximize my lead generating capabilities.
