When someone is selling a piece of property in or around the Melbourne area, they often want to do whatever they can to help make sure their property is presented at its best to achieve the best price. A Vendors Advocate will go a long way towards making the experience as satisfying as it can be, but also to obtain the best price for the home/investment they've already worked so hard to build. Sellers will use a Vendors Advocate for this very purpose.
On the opposite side of the fence is a property buyers agent who often engage, and essentially performs the same basic service on behalf of a Melbourne home buyer.
