The marketing of real estate or other items with an auction provides the buyer with the opportunity to bid on several items or properties in a short period of time.
As a buyer at an auction you are well aware of what other people are willing to pay for items or properties, letting you know that you paid only a few dollars more for the items or property.
With most of the information that the buyer needs to make an informed decision already gathered and made available to them for their consideration. This greatly reduces the buyers investment in time and resources in gathering this information for themselves.
