Absolutely! The builder has agents that work directly for them (the seller)- generally in the model home, etc. You need an agent to represent you and your best interest as the buyer. Look for an accredited buyer's agent -with an (ABR) Designation. The Buyer's Agent may also recommend certain types of inspections to be done prior to closing, as a contingency in the contract. Speaking of contracts and paperwork- everything must be in writing and it is considered a legal contract once all parties agree. With all of the forms, disclosures, documents, and legal-ease, you would want someone to explain it to you and what your obligations are as the buyer/purchaser. They can also help write certain things in the contract, that benefit you! They can look up recent sales, concessions the builder gave, etc.
