Here is how it actually works.
You drive out to a model home on a Saturday. Someone friendly meets you at the door, walks you through the plans, talks lot premiums, and hands you a card. That person is a licensed agent. They are the builder's agent. Their job is to get the best outcome for the builder, and they are good at it.
Most builders in this market require a buyer to register their own agent on the first visit. Show up alone, sign in alone, and in a lot of communities you have just given up your right to representation on that purchase.
The part that surprises people: bringing your own agent almost never raises your price. The builder has already budgeted the commission into the deal. Coming in unrepresented does not get you a discount. It just means nobody in the room is reading the contract for you.
So the ask is simple. Before your first model home visit, tell me where you are going. I will register with the builder, and from there you have someone on your side of the table.
