A person will find it difficult to sell a house if he has no experience. An experienced person will also have a wider network of buyers so there is a better chance of selling a house to them. These agents also know how to convince a buyer to complete a transaction. A realtor will know the best place and ways to market the property. A properly marketed house will mean that it will be noticed by a large number of buyers at a single point in time.
