I see there are links to submit offers for all states and some listings have bid amounts posted although they do not state if these are accepted offers or if they are advertising for higher offers to beat the posted offers.

Must real estate agents place the bid like a HUD property or can any buyer place a bid.

What involvement will the listing agent have in this new offer process (such as making sure the offers are from qualified buyers)?

Will the listing agent still get a commission?

I would imagine commission would be 1/2 of the current amount offered. There is a clause in the listing agreements to that effect if Seller finds a buyer.
