Further, the planning and zoning boards have declined my request for the special permit because one of the 4 units is a garage apartment which doesn't meet code because its detached.  

I "requested" two local RE groups that list rentals but is there an overall page? 

A few days later we sent thru our request and they wont budge.There are a few days left on the inspection period and the seller has twice asked us to send docs releasing them from the contract so they can proceed with another deal.

I think @Aaron Merriman is on the right path with requesting that the property be delivered vacant.  

If you are worried about you end buyer seeing how much you made on your assignment fee you can author your assignment in such a way that it doesn't state the amount and you may request a "blind HUD" from the title company.Lastly, if you are dead-set on double closing your deals, you will either have to fund them yourself and wait on the backside buyer's funds or use a transactional funder.  

Will it be better to request the renter to pay by paypal?

If I ever see trash in the yard I'll stop in and 'request' they clean it up immediately.Now, my nice rental is across the street from some boarded-up and abandoned houses.

The last one I wanted I spent 3 months from the time I submitted an all cash bid until the time they requested the seller's financial statements.
