You are not legally required to hire a realtor for new construction, but going without one leaves you as the only person at the table without professional representation. The builder’s sales staff works for the builder. The purchase contract was written by the builder’s lawyers. And the commission a buyer’s agent would earn is almost always built into the home’s price whether you bring an agent or not. For most buyers, skipping representation saves nothing and gives up the one advocate whose loyalty runs to you.
No Law Requires an Agent, but the Builder Has a Full Team
Every state allows individuals to sign real estate contracts on their own behalf. No statute requires a license or a hired professional to buy a newly built home. That freedom applies whether you’re commissioning a custom home on your own lot or picking a floor plan in a tract development.
The builder, meanwhile, has a full team. The sales representative you meet in the model home is either a direct employee or a sub-agent of the developer, and their fiduciary duty runs to the builder. Their job is to move inventory on terms that protect the builder’s margins and keep pricing consistent across the community. They can walk you through floor plans and explain upgrades. They cannot give you unbiased advice about whether the price is fair, whether a clause puts you at risk, or whether you should push back on a term.
If you go unrepresented, the builder will likely ask you to sign a disclosure acknowledging that no one in the transaction is looking out for your interests. That document protects the developer from future claims that you were misled. It does nothing for you.
Skipping the Agent Rarely Lowers the Price
Builders typically budget buyer-agent commissions into their overall marketing and sales costs, usually around 2.5% to 3% of the base purchase price. Because that fee is a line item in the builder’s budget, buyers have traditionally paid nothing out of pocket for representation.
If you show up without an agent, the builder almost never drops the price by that amount. Most developers hold pricing firm to protect appraised values across the entire community. Cutting the price for one buyer could undermine every other homeowner in the neighborhood and cause problems with the builder’s own lenders. The unspent commission stays with the builder or gets redistributed as bonuses to the internal sales team. You pay the same price and get less help for your money.
The 2024 NAR settlement changed one piece of the mechanics. Since August 2024, any agent who uses a Multiple Listing Service must have a written buyer-broker agreement in place before touring a home with you. That agreement spells out exactly how much the agent will be paid and who pays it. For new construction, this means asking the builder’s sales office up front what commission they offer to outside agents, and using that number to set the terms of your buyer-broker agreement. If your agreement says 2.5% and the builder pays 2.5%, you owe nothing extra. If the builder offers less, you could be responsible for the gap, so negotiate the number knowing what the builder will cover.
Register Your Agent Before the First Visit
Builders enforce strict registration rules that decide whether they’ll pay your agent at all. Most require your agent to accompany you on your very first visit to the sales office or model home. Some allow online pre-registration through their website before you visit in person. Miss that window and the builder will likely refuse to compensate your agent.
This runs on a “procuring cause” standard: credit for the sale goes to whoever first introduced the buyer to the property. Walk into a sales office alone, sign the guest register, and hand over your contact information, and the builder’s system logs you as unrepresented. Adding an agent after that point becomes very difficult. You’ll either continue without representation or pay your agent from your own funds.
The fix is simple. Choose an agent before you start visiting developments. Driving through a community on your own to get a feel for the neighborhood is fine. Don’t step into the sales office, sign anything, or give your name until your agent is part of the process. One casual solo visit can cost you thousands of dollars in lost representation.
What’s Inside a Builder Contract
Resale transactions in most markets use standardized forms developed by local real estate associations. Builder contracts are different. They are proprietary documents drafted by the developer’s legal team, and they favor the builder on nearly every issue that matters.
A few provisions that catch unrepresented buyers off guard:
- Material substitution rights. Most builder contracts let the developer swap specified materials for alternatives described as “equal or better quality.” That language is vague enough to give the builder wide discretion, and buyers who don’t push for specifics often end up with cheaper finishes than the model home suggested.
- Escalation clauses. Some contracts let the builder raise the price if material or labor costs rise during construction. These clauses shift market risk to the buyer, sometimes with no cap.
- Earnest money forfeiture. Builder contracts often limit your ability to cancel without losing your deposit. Resale deposits are typically one to two percent; builders set their own amounts, and the forfeiture terms tend to be far less forgiving.
- Mandatory arbitration. Many builder contracts require binding arbitration instead of court. You give up your right to a jury trial, and the clause is drafted by the party that will benefit from it.
An experienced agent flags these before you sign. Without one, you’re relying on your own ability to parse legal language written specifically to protect the other side.
Where an Agent Earns Their Commission During the Build
New construction isn’t a single transaction. It’s a months-long process with several stages where things can go wrong.
Contract Review and Negotiation
The first and arguably most valuable service is reviewing the purchase agreement before you sign. Your agent identifies the escalation, substitution, arbitration, and cancellation terms and knows which are standard, which are aggressive, and which are worth pushing on.
Builders rarely negotiate on base price, but they often deal on other items. Closing cost credits, design upgrades, lot premiums, and interest rate buydowns are commonly negotiable, especially on homes already built and sitting in inventory. An agent who understands the builder’s incentive structure knows where the flexibility is and how to ask for it.
Independent Inspections
The builder performs its own quality checks, but those are internal reviews by employees on the builder’s payroll. Independent third-party inspections give you a separate set of eyes at the stages when problems are cheapest to fix.
The most valuable is the pre-drywall inspection, done after framing, electrical, and plumbing are roughed in but before the walls close up. An inspector examines the structural framing, wiring, and pipes while everything is still visible. Defects found at this stage cost a fraction of what they’d cost to fix later. A final pre-closing inspection covers the finished home; your agent helps build a punch list of cosmetic and functional issues and makes sure the builder documents each item with a commitment to complete repairs before closing.
Financing Oversight
Your agent monitors the mortgage process and verifies that all builder incentives, such as closing cost credits or rate buydowns, show up correctly in the final loan documents. Builders process hundreds of transactions and mistakes happen. Having someone whose only job is watching your deal makes those errors far less likely to reach the closing table.
Government-backed loans add another layer. VA loans require the builder to certify that construction meets or exceeds VA minimum property requirements and to submit specific documentation to the VA.1Department of Veterans Affairs. Builder Information and Certifications VA Loan Guaranty Program Not every builder participates in VA or FHA programs, and those that do have registration and documentation obligations that can slow the process. An agent who works with government-backed loans in new construction knows which builders in a given market are set up for these programs.
The Preferred Lender Trap
Builders frequently offer incentives, such as closing cost credits or free upgrades, that depend on using the builder’s affiliated lender. Those incentives can run $10,000 to $20,000, so the pressure to stay in-house is real.
The problem is that the builder’s lender may charge a higher rate or higher fees than what you’d find independently. A slightly higher rate over a 30-year mortgage can cost tens of thousands more than the incentive saved you. The builder’s lender also has less reason to compete on price because you’re effectively a captive customer once you’ve signed a contract with incentives tied to their financing.
Get a competing quote from at least one outside lender before committing. Compare the total cost of the loan over its full term, not just the monthly payment. If the outside lender’s rate is lower, ask the builder whether they’ll match it or let you keep the incentives with outside financing. Some will. An agent who handles new construction regularly has seen this negotiation play out many times and can tell you when the builder’s offer is genuinely good and when it’s subsidizing a more expensive loan.
When Going Without an Agent Makes Sense
For most buyers, the math favors representation. Self-representation is reasonable in a few situations. If you’ve bought new construction before, understand how builder contracts work, and are comfortable reviewing legal documents on your own, you may not need someone walking you through the process. If you’re building a custom home with your own architect and contractor rather than buying from a production builder, the transaction looks different enough that a traditional buyer’s agent may not add much.
Even then, hire a real estate attorney to review the contract before you sign. A one-time legal review costs far less than an agent’s commission and catches the contract provisions that create the most expensive problems. The attorney can flag arbitration clauses, escalation language, and forfeiture terms you might otherwise accept without realizing what you’re agreeing to.
