She mentioned to me that items under the property to secure the foundation was not completed and began to tell me what was wrong.

As a buyer, most deals presented to me from a wholesaler either have the value of the property over inflated, the costs of the rehab under estimated, or frequently both.   

Any links or names of things I should study would be really helpful to me.

I'm not sure if this is a typical strategy, but it makes sense to me.

His note to me last week:Thanks for the listing and the comps, but I do not see the opportunity.

Other investors, agents, etc in town who know that I buy houses and they wholesale them to me.

It seems to me that the turn around time of one business day is almost not realistic when wholesaling.

He mentioned that he has not worked out market pricing on all of his properties and does not have an updated profit/loss/expense sheet on every one at this time but he would get it to me hopefully by the end of this week.  

This seems insane to me. 

I'd give them a 30 day notice since they have been good to me and potentially become business partners in the furture when he opens the door.
