Why use a realtor? It helps to have a professional working with you, Somebody who knows all the aspects of the industry and can be honest with you in making the right choice. In new construction, a Realtor knows the best and not so best builders in the area and can help you avoid some of the downfalls of certain contractors. And the biggest plus when buying a new construction home is the buyer doesn't have to pay a commission.
