What a new build in Decatur costs to own
Take the median $419,275 new home with 20% down at today’s 6.71% 30-year rate: principal and interest run about $2,167/month. Georgia taxes 40% of value: at DeKalb County’s typical unincorporated millage of 34.42, property tax runs near $5,703/year after the standard homestead exemption; inside city limits add the city millage, and the first-year bill on a new build is usually on the land alone with the full bill the year after. All in, plan on roughly $2,642/month plus insurance, which runs well below Florida’s coastal premiums for most of Georgia — get a quote on the address; a new roof and current code usually earn the best rate.
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.
