The agent tells me the seller is motivated to sell the property and had no idea the condition it is in (he's out of state), but after two weeks of submitting the new offer the seller has neither accepted nor rejected our new offer.

That I'd have no idea about, there is also the Transactional Broker/agency relationship, where the listing agent has no obligation to either except to facilitate the transaction. 

I tried posting on craiglist, and found a few, but I was wondering where else I may find some more if anyone had some ideas.

To give you an idea on some recent numbers I've personally dealt with.  

So if the pro's think doing 1 wholesale deal a month making $5,000 committing 15-20 hours a week into it is a crazy idea, then it may not work, however if it is completely within the realm of possibility to make 1 or more deals a month part time then it would be well worth trying it for a year and see where it goes. 

I have no idea where to start.

It's a great idea, as long as the numbers work out. 

That is an idea we have been thinking about - prior board had some initial conversations with the fee holder but it stopped there for the time being.  

just SFR or multiplex, well that's the main idea.

I think that is a great idea however I have a small time line to close probably 2 weeks.
