Buyers often assume that a Realtor is not necessary for the purchase of a new home, and that, by not using a Realtor, they can save the cost of the commission off the purchase price. Because of the high percentage of sales of new homes made by Realtors, the major builders include a commission in the price of all of their homes, and do not negotiate or reduce the price if there is no Realtor representing the Buyer. They just make a higher margin. Therefore, a Buyer can have the representation of
an experienced Realtor at no additional cost

Some facts worth considering are:

Builders are not equal with regard to craftsmanship, customer service or desirability, even by different site location,
The builder's agent does not represent you,
The builders contract heavily favors the builder (and not you),
Realtors can offer a comparison of builders, locations and resale information as well as advise on marketability, lots, floor plans, and options,
Realtors can offer assistance in negotiating the best package of price, financing and options,
Realtors can offer assistance in coordinating the review of construction phases, outside inspections, walk through inspections and completion of final make ready, and
A Realtor as your representative, can be a sounding board, reference and go-between in negotiating with the builder.
