Buyer's guide
You Visited a Builder Without an Agent. Now What?
The registration rule, what it actually costs you, and whether it can be fixed
By William Zhang, Austin Realtor · Updated
The short answer
Most Austin builders require your agent to be registered on your first visit to their sales office. If you walked in alone and signed the guest book, many builders will refuse to pay a buyer agent commission on that community afterwards, which means you either proceed unrepresented or pay an agent yourself. It is sometimes recoverable if you have not yet signed anything and you raise it immediately, and it is not recoverable at all at some builders.
What actually happened when you signed the guest book
The guest book is not a courtesy. It is the builder registering you as a buyer who arrived without representation, which means they do not owe a buyer agent commission on your purchase. Some builders treat that as permanent for that community. Others apply a window of thirty or ninety days. A few will reconsider if your agent calls before you sign anything.
The policy is set by the builder, not by law and not by the MLS, so it varies. What does not vary is that nobody in the sales office is going to volunteer that you have just given something up.
What it costs you
The commission itself is the smaller part. On new construction the builder pays it out of a marketing budget, and buyers who arrive unrepresented do not get a discount for it. The sales price does not drop because you came alone.
The larger cost is that you now negotiate against a professional with no one on your side. The builder's sales agent is pleasant, knowledgeable, and paid by the builder. You also lose the person whose job is to push for a better incentive package and to tell you to have an attorney look at the paperwork before you sign it.
What to try, in order
Move quickly. Every one of these gets harder the further into the process you go, and none of them work once you have signed.
- Have an agent call the sales manager, not the on-site agent. The sales manager has discretion the on-site agent does not.
- If you only toured and gave no contact information, you may not have been registered at all. Ask what is on file before assuming the worst.
- If the builder applies a time window rather than a permanent bar, find out the date and work to it.
- If this community is barred, ask which of that builder's other communities are not. The registration is usually per community.
- Consider a different builder. There are two dozen active in the metro and the one you happened to visit first is rarely the only fit.
What not to do
Do not have an agent claim they were with you when they were not. Builders check, the sales office keeps records, and it puts the agent's licence at risk for a commission.
Do not assume that going unrepresented earns you a better price. It does not. It removes the person whose job is to push for a better package, keep the deadlines from slipping, and tell you when something belongs in front of an attorney.
I am a licensed Texas real estate agent, not an attorney. Nothing here is legal advice, and I do not interpret builder contracts, addenda or warranty terms — that is a real estate attorney's job, not mine. What I can do is represent you through the negotiation, the inspection and the walkthrough, and tell you when something belongs in front of a lawyer.
Answered
Can I add a realtor after visiting a builder alone? ▾
Sometimes, and it depends entirely on the builder's policy and how far you have gone. If you have only toured and have not signed anything, an agent calling the sales manager immediately is worth trying. If you have signed anything, including a reservation or a registration card, most builders will not allow it. The single deciding factor is speed, so make the call today rather than after the weekend.
Do I save money by not using a buyer agent on new construction? ▾
No. The builder does not reduce the sales price for an unrepresented buyer, because the commission comes from a marketing budget rather than from your price. What you save is nothing and what you give up is representation through the negotiation, the inspection, the orientation walkthrough and the closing. At most builders those are the four points where money is actually won or lost.
How long does builder registration last? ▾
It varies by builder. Some treat the first visit as permanently determining representation for that community, some apply a thirty or ninety day window, and a few have no formal policy at all. Because there is no standard, the only reliable answer comes from asking that specific builder's sales manager about that specific community.
