You are not required to have your own agent to buy new construction, but the builder's sales representative works for the builder. Most builders permit and budget for buyer representation, and almost all require your agent to be registered on your first visit to the sales office. That timing rule matters more than anything else in this question.
| The builder's sales agent | Your own agent | |
|---|---|---|
| Works for | The builder | You |
| Registration | Already in place | Must be registered on your first visit, or most builders will not recognize them |
| Negotiation | Presents the builder's terms | Pushes on incentives, upgrades, lot premium and contract terms |
| Inspection | Not their role | Arranges independent inspections during the build |
| Cost to you | None | Set in your written buyer agreement; builders often contribute |
The sales representative is knowledgeable, professional, and employed by the builder. Their duty runs to the builder. That is not a criticism; it is the structure, and pretending otherwise helps nobody.
They can tell you everything about the product. They are not there to tell you whether the lot premium is recoverable at resale, whether this quarter's incentive is generous relative to what the same builder offered in March, or what the community will look like when the remaining phases are finished and the construction traffic stops running past your lot.
Almost every builder requires a buyer's agent to be registered on the buyer's first visit to the sales office, frequently by accompanying them in person.
Register late and the builder can decline to recognize the representation for that transaction. Not reduce it. Decline it.
This single rule causes more avoidable problems in new construction than anything else. If there is any chance you want representation, bring your agent the first time or register before you walk in. There is no retrospective fix, no appeal, and no amount of goodwill that reliably undoes it.
If you have already visited unaccompanied, say so before you engage an agent, so you both know where you stand.
The contract. The builder's contract is not the Multi-Board Residential Real Estate Contract. It is the builder's own form, and its provisions on construction delays, change orders, substitution of materials, warranty scope, dispute resolution and deposit protection are drafted in the builder's favor. Your attorney reviews it. Your agent tells you which of those terms this particular builder actually moves on, which is different information.
Upgrades. Which ones hold value and which are money you will never see again. Structural options generally outperform finishes, because you cannot add a bump-out later but you can change a backsplash.
Lot premiums. Whether the premium on a pond lot or a cul-de-sac position is recoverable at resale in this specific community.
Timing. Where this builder is in the phase, and whether waiting eight weeks changes the offer.
The phasing. What is going up behind you, and when.
Generally not. Builders typically budget buyer representation as a cost of sale, and base price does not usually move according to whether you bring an agent.
Since the NAR settlement practice changes took effect on August 17, 2024, your compensation arrangement with your agent sits in a written buyer representation agreement, and whether the builder contributes toward it is agreed with the builder.
Confirm that arrangement before you register, not after. Your buyer agreement should also address what happens when you buy from a builder, because a general agreement written for resale purchases can leave both of you unclear.
Base price is the line builders defend hardest, and for a rational reason: the recorded price sets the comparable value for every unsold home in the community. Discounting one home devalues the rest of their inventory.
So they hold price and move on everything else.
What actually moves: design center allowances, upgrade credits, closing cost contributions when you use the affiliated lender, lot premiums, and occasionally a rate buydown.
And timing. A builder closing out a phase, or closing a fiscal quarter, or holding a finished spec home through a slow month, behaves very differently from one opening a new release with a waiting list.
Ask what is standing inventory. That is where the flexibility is.
New does not mean flawless, and municipal inspection does not mean inspected on your behalf.
The municipal inspector checks code compliance. The builder's internal quality process checks the builder's standards. Neither is working for you, and neither produces a report you own.
Standard practice is two independent inspections: one at the pre-drywall stage, when framing, rough plumbing, electrical and mechanicals are still visible, and one before closing. The pre-drywall one is the valuable one, because after the drywall goes up those issues are expensive to find and expensive to fix.
Builders confident in their work rarely object. A builder who does object has told you something useful.
Worth separating, because the risks and the negotiating positions are not the same.
A spec home is already built or substantially complete. You can see what you are buying, the inspection is straightforward, the timeline is short, and the builder has capital tied up in it. That last point is why standing inventory is where the flexibility lives, particularly near the end of a quarter or a phase.
A to-be-built home is a contract for something that does not exist yet. You select the lot, the plan and the finishes. You get what you want, and you accept construction risk: delays, material substitutions, cost escalation clauses in some contracts, and the possibility that the finished product differs from the rendering in ways you did not anticipate.
The contract terms that matter differ accordingly. On a to-be-built, read the delay provisions, the substitution rights, any escalation clause, what happens to your deposit if the builder does not complete, and what your remedy is if the completion date slips past your financing lock or your lease expiry.
On a spec, read the warranty and get the inspection.
The builder's affiliated lender will offer incentives. Those incentives are often genuinely worth having, and the arrangement is legal and disclosed.
What you should still do is get a competing quote. Compare the total cost, meaning rate plus points plus fees, net of the incentive. Sometimes the affiliated lender wins comfortably. Sometimes the incentive is smaller than the rate premium and you are better off elsewhere, taking the loss of the incentive.
You are entitled to use your own lender. Builders sometimes make this awkward and occasionally condition incentives on using theirs, which is permitted as long as you are not required to use them to buy the house.
Two timing issues specific to new construction. On a to-be-built, your rate lock has to survive the build, and extended locks cost money. And the appraisal happens against a home that does not exist yet, using the plans and the comparables, which occasionally produces a shortfall at the end of the build that nobody anticipated at contract.
Before closing you will do a walk-through and produce a punch list of items for the builder to correct.
Do it in daylight. Take your time. Bring the inspection report and check every item on it. Open every window and every door, run every tap, test every outlet, run the HVAC in both modes, check the grading around the foundation and the direction the downspouts discharge.
Get the punch list in writing, signed, with dates for completion.
And understand what happens after closing. Once you have closed, your leverage is the warranty and the builder's reputation, not the money. Items promised verbally at the walk-through and not written down have a way of not happening once the sales office moves to the next community.
This is unglamorous and it is the single highest-value hour in the whole purchase.
Ask what the warranty actually covers, for how long, and who administers it. Structural, systems and workmanship warranties typically run on different clocks.
Ask how warranty claims are handled after the sales office closes and the team moves to the next community, because that is when most claims arise.
And ask what the dispute resolution clause says. Many builder contracts require arbitration. That is not automatically bad, but it is a term you should know you agreed to.

You are not required to have one, but the builder's sales representative works for the builder rather than for you. Most builders permit and budget for independent representation, and it is what gets you advice on lot premiums, upgrade value, phasing and which contract terms this builder actually negotiates.
Almost always on your first visit to the sales office, often by having the agent accompany you in person. Register late and the builder can decline to recognize the representation for that transaction, and there is no retrospective fix. Bring your agent the first time or register before you walk in.
Generally not. Builders typically treat buyer representation as a budgeted cost of sale and base price does not usually move according to whether you are represented. Your compensation sits in your written buyer agreement, and any builder contribution is agreed separately before registration.
Yes, though rarely on base price, which builders defend because the recorded price sets the comparable value for their unsold inventory. Design center allowances, upgrade credits, closing cost contributions and lot premiums are where movement happens, particularly on standing inventory near the end of a phase.
Yes, and ideally twice. A pre-drywall inspection while framing, plumbing, electrical and mechanicals are still visible, plus one before closing. Municipal inspections check code compliance and the builder's process checks their own standards, and neither produces a report that belongs to you.
