Thanks Andrew for replying. Yes we have had a bank valuation done as well as three agents come out to look at the house. They all want to charge for advertising so I was surprised when I read don’t pay for advertising before your property is sold. That is why I asked for others opinions.
Two of the agents quoted us much less than the bank valuation as the starting price range and the third quoted around what we would like to sell the property for. I could ask the third agent for a written guarantee to sell the property at the price he quoted as a test if he is genuine.
