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.

@Jack Hensy,How do you feel about changing your mailing address and utility accounts every six months or so?

That will show owner and primary address.
