Some of the providers also give a lot of discounts and incentives in form of coupons and others.

Would you say the houses you got at a significant discount twere on #the market longer?

Account Closed if you are interested in flipping houses I would highly recommend getting J Scott's book at http://get.biggerpockets.com/flippingbook/ which has a 20% discount this weekend using code "thanksgiving". 

@Gail Kaitschuck the coupons at a discount are a great idea.

Is there any discount value on the table, forced appreciation, or just general appreciation in the future?

because of this, they have no incentive to offer to a "real estate investor" who will "pay cash and close within 10 days" with a 20, 25 or 30 percent discount.  

Don't believe in net worth in RE either, I've seen my net worth declined by 5 times in 2008, because I had a lot of ''equity''.I only believe that true wealth is a future cash flows discounted at desired rate of return

So they are not all motivated to the point where they are ready to give up huge discounts but some are pleasant and willing to sell.

How much,  if any,  should I discount ARV? 

Christopher has done some double dipping on discounts over other costs, banging the seller twice.None of this is a basis at an offer, that 70% BS is for two closings and holding costs, wholesalers don't hold the property!!!!
