    Do You Need a Realtor for New Construction?

    Short answer: yes, and in almost every case the builder, not you, pays for it. Here's exactly what your own agent does on a new build, and what you give up by walking into a model home alone.

    Written and reviewed by Carla Goddard, Founder & CEO, Vicinity. Last reviewed September 12, 2026.

    You don't have to use a real estate agent to buy a new construction home. You can walk into a builder's sales office, choose a floor plan, sign the builder's contract and buy directly from the builder. So why would you use a buyer's agent? The answer isn't that new construction is impossible to buy on your own. It's that buying directly from the builder and having someone represent your interests are two different experiences. Understanding that difference, and knowing what to look for in an agent if you want one, can help you make a better decision.

    First, Understand Who Works for Whom

    Walk into a new construction model home and the sales representative may be incredibly helpful. They'll show you floor plans. They'll explain the community. They'll walk you through available homesites. They'll explain upgrades. They'll discuss incentives. They'll answer questions about construction. That's their job. But the builder's sales representative works for the builder. A buyer's agent represents you, subject to the terms of your representation agreement and applicable state law. That's an important distinction. It doesn't mean the builder's representative is doing anything wrong. It means the two professionals have different responsibilities. The builder is trying to sell you a home. Your agent's role is to help you evaluate the purchase from your side of the transaction.

    New Construction Realtor FAQs

    Do you need a realtor to buy a new construction home?
    You are not legally required to have one, but you should. The agent sitting in the builder's model home is paid by the builder and represents the builder's interests. Your own buyer's agent negotiates upgrades and incentives, reviews the builder's contract, tracks construction milestones, and attends inspections on your behalf. In most new construction transactions the builder's marketing budget already covers a buyer-agent commission, so representation typically costs you nothing extra.
    Does using a realtor make a new construction home more expensive?
    No. Builders set base prices from their own pricing model and do not discount for unrepresented buyers, the co-op commission is a line item in the marketing budget that the builder keeps if you show up alone. What changes is who advocates for you on upgrades, lot premiums, and closing-cost credits. Represented buyers routinely capture incentives that unrepresented buyers never hear about.
    When do I need to register my agent with the builder?
    On your very first visit, before you sign the visitor card. Nearly every builder has a first-contact registration rule: if you tour alone and register yourself, the builder can refuse to recognize an agent you bring in later. Have your agent accompany you on the first visit, or at minimum list them by name on the registration card.
    What does a new construction agent actually do that I can't?
    Four things. They read the builder's purchase agreement, which is written by the builder's attorneys and is very different from a standard resale contract, and flag arbitration clauses, escalation clauses, and delay provisions. They price upgrades against third-party costs so you know what to take from the design center and what to do after closing. They uncover recurring costs the sales office understates: CDD or MUD bonds, HOA capital contributions, and lot premiums. And they schedule independent pre-drywall and final inspections that the builder is not obligated to suggest.
    Can I use the builder's sales agent as my agent?
    You can, but it is dual representation at best and pure builder representation in most states. The onsite agent's fiduciary duty runs to the builder. Anything you tell them, your true budget, your timeline, your willingness to waive an inspection, is information the builder can use. There is no cost saving in exchange for giving that up.
    How do I find an agent who specializes in new construction?
    Look for a track record with production builders in your market, familiarity with the local special-district structure (CDD in Florida, MUD/PID in Texas, Mello-Roos in California), and a credential specific to new construction rather than general resale. Vicinity's Certified New Construction Specialist (CNCS) agents are trained and verified against that standard, you can browse certified agents by market.
