About New Construction Homes in Key Biscayne

New Construction Homes in Key Biscayne, FL

New Construction Homes are a distinct slice of the Key Biscayne, County market. New construction in Key Biscayne ranges from quick move-in homes that are already built to to-be-built homesites where you choose the floor plan and finishes. Builders active across County include national and regional names, and a to-be-built home usually takes several months to about a year to complete. New homes bring modern layouts, current energy and hurricane codes, and a builder warranty.

Much of the personalization happens at the design center, where upgrades add up quickly, so set a budget first and learn which choices hold resale value. New homes still deserve inspections, both during construction and before closing, and most carry a warranty, commonly one year on workmanship, two on systems, and ten on the structure. Many new Florida communities also carry a CDD assessment on the tax bill, separate from HOA dues. Builders often extend their best incentives through a preferred lender or on quick move-in inventory near the end of a quarter, and your own agent costs you nothing because the builder pays the buyer-side commission.

Frequently Asked Questions

New Construction Homes in Key Biscayne FAQ

Are new construction homes in Key Biscayne move-in ready or to-be-built?+
Both. Builders usually have a mix of quick move-in homes that are already built and to-be-built homesites where you pick the plan and finishes. Ask us what inventory and homesites are available now.
Can I use my own agent to buy new construction in Key Biscayne?+
Yes, and it costs you nothing. The builder pays the buyer-side commission, but in most cases your agent must be with you or registered on your first visit, so arrange representation before you tour.
Do new homes in Key Biscayne come with a warranty?+
Almost always. New homes typically carry a builder warranty, commonly one year on workmanship, two years on major systems, and ten years on the structure. Confirm the exact coverage before closing.
What is a CDD fee on new construction in County?+
A Community Development District assessment repays the bonds that funded the community's roads and utilities. It appears on the property tax bill, separate from any HOA dues, so factor it into your monthly cost.
