What a new build in St. Johns costs to own
Take the median $559,999 new home with 20% down at today’s 7.18% 30-year rate: principal and interest run about $3,035/month. St. Johns County’s typical millage of 13.47 puts property tax near $6,869/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. Citizens’ average premium in St. Johns County is about $1,378/year; a new roof and current code usually earn a better private quote than that average. Where an HOA is listed the median is $20/month. All in, plan on roughly $3,742/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.
