Most properties are saleable by auction, though not every property. Residential property, commercial property, vacant land, and occasionally even boat slips are all sold at auction. Some sellers may try to sell unsuitable, unmarketable property. These types of properties would be properties that have been on the market too long at their retail price that have not adjusted for the changing market accordingly. These properties do not do well at auction. The majority of real estate properties that can be marketed effectively do extremely well at auction. The best auction marketing companies will 1) know the market and 2) analyze the property closely to ensure success for both the buyer and the seller before accepting a property to market.
