Big question. Where is the seller going to get the $200k cash back to rebate to you? If the seller is going to loose his 200k downpayment anyway, why would he sell and give it to you?
In order for this to work, there needs to be something in it for the seller.
The seller might go with a 100k cashback. But then you might be overpaying for the house even with the cashback.
