Certain property eligibilities allow Good Neighbor Next Door participants, HUD registered nonprofit organizations, and/or government entities to bid on the property prior to becoming available to Owner Occupant bids. These properties, which are usually located in HUD designated revitalization areas or are determined to be uninsurable, are available in the Lottery period for seven (7) days. If there are no winning bids when the Lottery period ends, these properties then enter the Exclusive Listing Period for 5 or 30 days, depending on the insurability of the property.
