For folks who said they didn't know how long it's been on the market, if you check the MLS daily (um, obsessively), you'll learn which numbers are the newest.
Can you have your realtor just relist you? Same price, same everything, just give you a new MLS number to put you back at the top of the pile? That way an agent would actually have to pull the report on your house to see how long you've been on the market, but buyers would think it's a new listing.
I, like the others, would go lower on my offer, but wouldn't not look. I have a good eye and can see the bones of a house and often think lots of houses get looked over because of things that are easily changed (decor being the biggest).
