Short answer: When you buy a new-construction home, the friendly sales rep in the model home works for the builder, not for you. Their job is to protect the builder's price, terms, and margin. To have someone whose loyalty is contractually to you — reviewing the builder's contract, negotiating upgrades and incentives, and managing inspections and warranty — you need your own buyer's agent. Bringing your own agent is little or no cost to you; how it is paid is settled per offer, in writing.
The on-site sales agent in the model home works for the builder. To have someone whose loyalty is contractually to you, you need your own buyer's agent — which in most Middle TN new-construction deals adds little or no cost to you; how it is paid is settled per offer, in writing.
The supporting facts
The on-site agent represents the builder. The builder's sales representative can be helpful and knowledgeable, but they are legally and financially aligned with the seller and are not obligated to advocate for your best interests (Keeping Current Matters).
Builder contracts are not the standard resale contract. Builders commonly use their own purchase agreements, written by the builder's counsel, with fewer contingencies than the local board's resale contract — meaning less built-in protection around financing, inspection, and getting your deposit back (The Goodhart Group; NAR).
Earnest money and option deposits are often non-refundable. New-construction earnest money commonly runs higher than resale, and deposits toward custom structural options are frequently non-refundable, since the builder can't easily resell personalized selections (Century Communities; MSR Communities).
Representation may protect your wallet. One former new-home sales agent, quoted by Orchard, estimated that unrepresented buyers paid roughly $20,000 more than represented buyers — an anecdotal figure, not a guarantee, but it points to where an advocate earns their keep (Orchard).

The value of your own advocate
A buyer's agent walks in on your side of the table. On new construction that means reviewing the builder's contract line by line before you sign, so you understand the deposit terms and what protections you do — and don't — have. It means asking for the incentives builders often extend (design-center credits, rate buy-downs, closing-cost help) rather than assuming the sticker terms are final. It means arranging your own third-party inspections at framing and before closing, and helping you use the builder's warranty when something needs attention after move-in. Builders build good homes across Middle Tennessee; our role isn't to second-guess them — it's to make sure your interests are represented as clearly as theirs already are. That representation is little or no cost to you; how it is paid is settled per offer, in writing.
Frequently asked questions
Can I just use the builder's on-site agent?
You can, but they represent the builder. Nothing requires them to negotiate the price down or flag terms that favor the seller.
Does bringing my own agent cost me more?
Bringing your own agent is little or no cost to you; how it is paid is settled per offer, in writing.
Do I need to register my agent before I visit?
Yes — this matters. Many builders require your agent to accompany or register you on your first visit for representation to apply. Loop us in before you tour a model home.
Is the builder's contract the same as a normal home contract?
No. Builders generally use their own agreements with fewer contingencies than the resale contract, which is exactly why a second set of eyes helps (The Goodhart Group).
Is my earnest money refundable?
Often less so than on resale, and option deposits are frequently non-refundable. We review the specific terms with you before you commit (Century Communities).
