what is the going rate to place a bid 500.00 or 1000.00?

Well that depends, the money you are talking about is "hand" money. It is to show the seller you are serious about purchasing the home. It should be enough that it hurts to lose it, but not enough to ruin you. It does go toward your closing costs. That being said, $500 could be enough if it is a low priced home (less than $50k). $1000 is more usual but may not be enough for a higher priced property ($300k and up). Hope this helps!
