The builder has a sales rep, why do I need an agent?

This post is part of the Complete Guide to Buying a Home in Katy, Fulshear, Cypress & Richmond — your start-to-finish resource for navigating the west Houston housing market in 2026.
It is one of the most common questions Bobby Mohebbi hears from buyers considering new construction in Katy, Fulshear, Cypress, Richmond, or anywhere in the Houston area: "The builder has a sales rep in the model home. Do I really need my own agent?"
The short answer is yes. The longer answer is that having your own buyer's agent when purchasing new construction is not just recommended — it is one of the smartest financial decisions you can make in the entire home buying process. And it costs you nothing.
Here is why.
The Builder's Sales Rep Does Not Work for You!
This is the most important thing to understand, and it is the one thing most buyers get wrong.
The person greeting you in the model home is friendly, knowledgeable, and genuinely helpful. They can walk you through floor plans, explain the design center options, show you available lots, and answer your questions about the community. They are good at their job.
But their job is to sell you the builder's product at the best possible terms for the builder. They are employed by the builder. Their commission is paid by the builder. Their performance is measured by the builder. When your interests and the builder's interests conflict, and they will, on pricing, contract terms, construction timelines, material substitutions, and warranty claims, the sales rep's obligation is to the builder, not to you.
This is not a criticism of builder sales representatives. It is simply how the relationship is structured. A buyer without their own agent is negotiating alone against a professional sales team backed by the builder's attorneys, preferred lender, and corporate pricing strategy. Having your own agent levels the playing field.
What a Buyer's Agent Does That the Builder's Rep Cannot
Your own buyer's agent brings a fundamentally different set of services to the transaction — services that protect your financial interests and that the builder's sales representative is not positioned to provide.
Your agent reviews the builder's contract before you sign. Builder contracts are 30 to 50 pages of legal language drafted by the builder's attorneys. They contain provisions around construction delays, material substitutions, change order pricing, and warranty limitations that directly affect you. Bobby Mohebbi reviews every clause with his buyers and explains what each provision means in practical terms. The builder's sales rep will hand you the contract and ask you to sign. Your agent will make sure you understand what you are signing.
Your agent negotiates beyond the published incentive. The advertised incentive package — the rate buydown, closing cost credit, and design center allowance displayed on the builder's marketing materials — is the opening offer. Your agent pushes for additional credits, reduced lot premiums, upgraded options, and better terms. Buyers who negotiate through an experienced agent save an average of $10,000 to $15,000 or more beyond the published incentives. For a full breakdown of how this works, read our guide to How to Negotiate with a Builder in Texas.
Your agent compares the builder's preferred lender against independent lenders. Most builders tie their incentives to using their preferred lender. But the preferred lender's base rate and fees are often higher than what an independent lender would offer. Bobby Mohebbi requires every buyer to get a competing quote so they can compare the total loan cost — not just the first-year payment — and choose the option that actually saves them the most money over the life of the loan.

Your agent verifies the property tax rate for your specific lot. Property tax rates in the Katy area vary significantly depending on the MUD district, school district, and county. Two lots in the same community can have different tax rates, and the difference can amount to hundreds of dollars per month. The builder's sales rep may quote the community average. Bobby Mohebbi pulls the exact rate for the specific lot you are considering. Read more in our guide to Property Tax Rates and MUD Districts in Katy, Fulshear & Cypress.
Your agent confirms school zoning for your exact address. School zoning in the Houston area is determined by address, not by community name. Some master-planned communities straddle multiple school districts, and the builder's marketing may not make this clear. Bobby Mohebbi verifies the exact school assignment before his buyers make an offer. Read more in our guide to Best School Districts Near Houston, TX.
Your agent monitors the construction process. Once you sign the contract, your agent stays involved throughout the build — tracking the timeline, attending key inspections, flagging any issues, and ensuring that what was promised in the contract is what gets delivered. The builder's sales rep moves on to the next buyer. Your agent stays with you until closing day and beyond.
It Costs You Nothing
This is the part that surprises most buyers. Your buyer's agent's commission is paid by the builder, not by you. The builder has already budgeted for this cost in their pricing model. Whether you use an agent or not, the builder's price does not change.
After the NAR settlement in August 2024, builders can no longer advertise commission offers on the MLS. However, virtually all Houston-area builders continue to pay buyer's agent commissions, typically 2% to 3% of the purchase price. This payment comes from the builder's side of the transaction. It does not increase your purchase price, your closing costs, or your monthly payment.
When you buy new construction without an agent, the builder simply keeps the commission they would have paid your agent. You do not get a lower price — you get less representation. The builder saves money, and you lose the only person at the table whose job is to protect you.
The Registration Rule: Why Timing Matters
Here is the practical step that trips up more new construction buyers than any other.
Most builders require your agent to be present or registered on your very first visit to the sales center. When you walk into a model home, the sales representative will ask you to sign a guest registration form. If you sign that form without listing your agent, the builder may consider you an unrepresented buyer — and they may refuse to pay an agent's commission later, even if you hire an agent before signing a purchase contract.
This means the time to connect with Bobby Mohebbi is before you start touring model homes, not after. A quick text or phone call before your first visit is all it takes. Bobby will either accompany you or register you in advance so your representation is documented from the start.
If you have already visited a builder without an agent, reach out to Bobby Mohebbi as soon as possible. In some cases, registration can still be established if you have not yet signed a purchase contract. The earlier you act, the better your chances.
What Happens When Buyers Go Without an Agent
Bobby Mohebbi has worked with buyers who initially tried to navigate the new construction process alone and came to him after running into problems. The patterns are consistent.
They accepted the builder's first incentive offer without realizing there was room to negotiate, leaving thousands of dollars on the table. They used the builder's preferred lender without comparing against an independent lender and locked into a higher permanent interest rate that will cost them tens of thousands over the life of the loan. They signed the builder's contract without understanding the delay provisions and were stuck in a lease for three extra months when construction ran behind schedule. They assumed their home was zoned to a specific school based on the community's marketing and discovered after closing that their section feeds into a different campus. They did not check the MUD tax rate for their specific lot and were surprised by a monthly payment that was hundreds of dollars higher than expected.
Every one of these situations is preventable. Every one of them is something Bobby Mohebbi catches as part of his standard process. And every one of them costs the buyer nothing to prevent — because the builder pays the agent's commission.

Frequently Asked Questions
Do I need a realtor to buy a new construction home in Texas?
You are not legally required to use an agent. However, having your own buyer's agent is strongly recommended. The builder's sales representative works for the builder, not for you. Your agent reviews contracts, negotiates incentives, compares lenders, verifies tax rates and school zoning, and monitors construction — all at no cost to you because the builder pays the agent's commission.
Does using a buyer's agent increase the price of a new construction home?
No. The builder's pricing does not change whether you use an agent or not. The builder has already budgeted for buyer's agent compensation in their pricing model. If you buy without an agent, the builder simply keeps the commission. You do not receive a lower price.
How do I register my agent with a builder?
Tell your agent before your first visit to any builder's model home or sales center. Your agent will either accompany you or register you in advance. Most builders require agent registration on the buyer's first visit. If you sign the builder's guest form without listing an agent, you may lose the ability to have an agent represent you in that community.
What if I already visited a builder without an agent?
Contact Bobby Mohebbi as soon as possible. In some cases, agent registration can still be established if you have not yet signed a purchase contract. The sooner you act, the better your chances of preserving your representation.
Do builders still pay buyer's agent commission after the NAR settlement?
Yes. After the NAR settlement in August 2024, commission offers can no longer be advertised on the MLS. However, virtually all Houston-area builders continue paying buyer's agent commissions, typically 2% to 3%. This is paid by the builder and does not increase your costs.
What does a buyer's agent do during new construction that I cannot do myself?
Your agent reviews the builder's contract (which is written to protect the builder), negotiates beyond the published incentive package, compares the builder's preferred lender against independent lenders, verifies the exact property tax rate and school zoning for your lot, monitors the construction timeline, and attends key milestone inspections. These are services the builder's sales representative cannot and will not provide on your behalf.
