The New Construction Buyer Playbook

The person in the sales office does not work for you

Every listing agent represents the seller. In a builder sales office the seller is the builder, and the friendly, knowledgeable person walking you through the model represents them. That is not a criticism, it is their job, and they do it well. It just means nobody in that room is obligated to put your interests first.

Under Florida law a buyer's agent owes you a fiduciary duty: put your interests first, keep your financial position and motivations confidential, and give you honest guidance even when it means talking you out of a home. That is a fundamentally different relationship than talking directly with the seller's representative, and it is the whole reason to bring your own.

The registration rule that decides everything

This is the single most expensive thing buyers get wrong, and it is unforgiving. Your agent generally must be registered with the builder on or before your first visit. Most builders will not add representation after you have signed in on your own.

That means a casual Saturday drive-through, the kind where you were "just looking," can permanently cost you representation in that community. It is not a negotiation, it is a sign-in sheet, and once your name is on it alone the door usually closes.

• Bring your agent, or have them register you, before your first visit to any community you might buy in.
• This applies to model-home tours, sales-center walk-ins, and community events alike.
• If you have already registered somewhere alone, say so early. It is better to know which communities are still open to you than to discover it at contract.
• Registration costs you nothing and commits you to nothing.

A builder contract is not the contract you are used to

Resale purchases in Florida typically run on a standard, widely used form contract with familiar buyer protections. A builder contract is the builder's own document, drafted by the builder's lawyers, and it does not necessarily give you the same rights in the same places.

That does not make it unreasonable, but it does make it worth reading carefully rather than skimming. Pay particular attention to what happens if construction runs long, what the builder may substitute, what your deposit does, and how disputes are handled. Read it before you sign, not after, because the leverage is all in the before.

Incentives, and what they are attached to

Builder incentives in this market are frequently tied to using the builder's preferred lender or title company. That can genuinely be the best deal available, and often is, because the incentive is real money.

It can also mask a rate or fee structure that costs more than the incentive is worth. The way to know is to shop it: get a competing quote from an independent lender and compare the all-in cost, incentive included, rather than comparing the incentive to nothing. If the preferred lender wins, take it with confidence. If it does not, you now have a number to negotiate with.

The design center is where investment ranges go to die

The base price gets you the base house. Structural options are decided early and cannot be added later. Finish selections happen at the design center, usually under time pressure, and the incremental cost of each choice is small while the total is not.

Two practical rules. First, set your upgrade investment before the appointment, in writing, and treat it as a cap rather than an opening position. Second, separate the choices that are hard to change later, structural changes, lot orientation, anything behind the drywall, from the ones that are easy to change later, which is most cosmetic finish. Spend where changing your mind is expensive.

The lot premium is a real negotiation

Homesite premiums for water, preserve, or corner lots are a separate line from the house price, and they vary enormously. A premium can be entirely justified, a preserve lot that will never be built behind is a durable value. It can also be a number attached to a view that a future phase will remove.

Ask what is planned for every parcel you can see from the lot, and get the answer against the approved site plan rather than the sales office's recollection. This is one of the highest-leverage questions in the entire process and almost nobody asks it.

The costs that surface after contract

New communities in Southwest Florida commonly carry a Community Development District assessment. A CDD is repayment of the municipal bonds that funded the roads, drainage, utilities, and amenities, and it is collected on your annual property tax bill as a non-ad valorem assessment, separate from your HOA dues. Newer communities carry fresher bonds, which is exactly why their CDD assessments tend to run higher than an older neighborhood's.

Property taxes behave differently on new construction too. During construction the tax bill is often based on land value only. Your first full bill, based on the completed home, arrives after the first January 1 following completion, and it can be a shock if you planned from the construction-period number.

• Ask for the CDD assessment for the specific lot, not the community average.
• Plan for the full post-completion tax bill at your purchase price, minus the homestead exemption if you will file for it. Never plan around the construction-period figure.
• Get an insurance quote before closing. Newer construction and a wind mitigation inspection can lower the premium meaningfully, and the quote is part of the real monthly cost.
• Confirm what the HOA covers on day one versus after the developer turns the community over to residents.
