What a new build in Port St Lucie costs to own

Take the median $454,990 new home with 20% down at today’s 6.76% 30-year rate: principal and interest run about $2,363/month. St Lucie County’s typical millage of 22.85 puts property tax near $9,256/year after the $50,000 homestead exemption — and on a new build there is no seller’s capped bill to be misled by; the first-year bill is on the land alone and the full bill arrives the year after. Where an HOA is listed the median is $242/month. All in, plan on roughly $3,377/month, plus any CDD assessment — most master-planned communities finance their infrastructure with a district bond that appears on the tax bill for years, and it is the number builders’ sales offices mention last.

How to buy new construction the smart way

The agent in the model home works for the builder. Bringing your own Momentum agent costs you nothing — the builder pays the commission either way — and gets you representation on the contract (builder contracts are one-sided by design), the upgrade pricing, the lender comparison (the builder’s preferred lender incentive is real but not always the best deal), an independent inspection at pre-drywall and at completion, and the walkthrough. Register your agent on your first visit; most builders will not honor representation after that.

Builders rarely cut list price on a to-be-built home, but completed inventory homes at the end of a quarter are a different negotiation: closing-cost credits, rate buydowns, and included upgrades are common, and the cards above show which homes have been sitting.

Should I use my own agent to buy new construction?

Yes. The sales agent in the model home represents the builder. A Momentum buyer's agent costs you nothing — the builder pays the commission — and handles the contract, upgrade pricing, lender comparison, inspections, and the final walkthrough. Register your agent on your first visit.

Do builders negotiate on price?

Rarely on the list price, but they routinely offer closing-cost credits, rate buydowns, and included upgrades, especially on completed inventory homes at quarter-end. That is where a buyer's agent earns their keep.
