A property agent handles not only marketing, but actually a broad range of processes. Most importantly, the agent will conduct a market analysis.
Is a market analysis really that important? Actually, yes. It is crucial because it will show the ability of the property to be sold at the best price and at the best time.
There are many other processes handled by a property agent, from A-Z. From the moment an owner thinks of selling until the deal is closed and the ownership is transferred. That is the role handled by the real estate agent.
