There are a number of reasons for selling at auction but the main ones are: 

• Certainty that the Sale will go through provided that the reserve price is reached on the day.
• Completion within a Short Timescale – typically within 8-10 weeks of being instructed.
• Best Price achieved on certain lots (e.g. plots or land with or without development potential, attractive properties in highly sought after locations.
• Market Price achieved for certain properties which are hard to price (e.g. properties with structural problems, short leases, unusual construction types).
• Choice of Special Conditions which can be attached to the sale (e.g. you sell a plot of land at the bottom of the garden with a restrictive covenant that the property built cannot be higher than a single story so as not to overlook your existing property).
