Here's the thing nobody tells you walking in the door: that gorgeous model home was decorated to sell the community, not to show you what the base price gets you. The countertops are frequently an upgrade tier. The flooring throughout is often a step, or three, above standard. The cabinet hardware, the tile backsplash, the lighting package, a lot of it is there to make you feel something, and feelings are exactly what get people to overspend on options they didn't plan to buy.

Ask directly: "Is this specific model built at the base price, or does it include upgrades? Which ones?" A good sales rep will walk you through it room by room without getting defensive. If you get a vague answer, push for specifics before you compare this home's price to anything else you're considering.

This is the one. The person who greets you at the door, offers you water, and walks you through the floor plan is genuinely knowledgeable and usually pleasant to work with. They also work for the builder, not you. Their compensation is tied to the builder's success, not yours, and that's not a criticism, it's just the job. The Consumer Financial Protection Bureau notes directly that real estate agents can represent the buyer, the seller, or sometimes both, and that you're entitled to know exactly who's representing you and under what terms, before you're deep into a conversation about floor plans and upgrades.

Here's the part that catches buyers off guard: this isn't a decision you get to make after your first visit. Most builders require your own agent to be physically present with you on that very first tour in order to honor their representation, and commission, later, even with a signed agreement in hand. Tour alone first, even "just to look," and you can lose that option for the rest of the transaction. I've covered exactly why this rule exists, and what it protects you from, in do I need a Realtor when buying new construction.
