Not sure / either
When choosing an agent type you should consider the following.
A local agent will offer a more personalised service where you are guided through the sale process and much of the work associated with preparing, advertising, viewing and negotiating is done for you by a local professional.
Some Internet agents although cheaper may not offer the same personalised service a local agent can, you may also be charged if a sale has occured or not.
No cashback offers are currently available for internet agents.
