I tried to explain that I had a marketing list and that I don't know which "John" he is, so without further information I was likely to mail to him again. 

They may give you the information you need to help evaluate if you should proceed.

Trying to get my head wrapped around all this information.

If a buyer says anything the agent has a duty to inform the seller, if the seller says something the agent has no duty to inform the buyer.

Definitely a lot of useful information.

But it sounds like the lenders that have been soliciting you are people you don't know, so I would tread very carefully and not give out any personal information until you know who you're dealing with.

They are very informative.

@Erin Donlan  the intent was not to mislead, but to inform.  

Lots of great information here.

To give some more information on my plan, I am in the beginning stages of contacting lawyers, agents, contractors, mortgage brokers, and hard money lender to build out my contact list.Simultaneously, I am beginning to develop systems for generating leads.I have been listening to the BP Podcast for the past year and it has been a tremendous help in driving my interest in REI.
