This dynamic is common with brand new listings and listings that have been on the market for a few weeks.

Eight showings over the first three days, but no offers.  Then, an offer is received, other showing agents are notified, and three more offers are submitted.

Nine showings over the first three weeks, but no offers.  Then, an offer is received, other showing agents are notified, and two more offers are submitted.

It's almost as if some buyers need to know other people want to buy a house before they are willing to decide they want to buy the house.

So...

Sellers - Don't despair if you don't have an offer yet - when an offer comes in, it could actually result in more than one offer.

Buyers - Who will you be?  The first buyer to make an offer, or will you wait until someone else does and then jump in?
