I was informed that the tenants were on a month to month lease.  

A few days after getting the offer signed the seller contacted me & informed me that she just found out the courts don't recognize her as the executor because there wasn't anything in writing from her parents like a will stating her as the executor.

In reality the information can be learned by someone in about 15 hours, but state mandates require 75.

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.
