Direct answer

A spec or inventory home is built, underway, or planned by the builder for sale without being fully designed around one buyer. Terminology varies by builder. A to-be-built home begins from a buyer's selected plan, lot, and options after contract.

The farther along the home is, the shorter the financing and rate-risk window may be. A to-be-built contract usually creates more selection decisions, deposits, timeline exposure, and opportunities for the buyer's finances to change before closing.

What does this mean for a Northeast Florida buyer?

In Northeast Florida, the answer should be tested against the builder's actual contract, community, expected completion range, taxes, insurance, HOA or CDD obligations, and the buyer's current approval. Jacksonville, St. Johns, Clay, Nassau, and Flagler County transactions do not share one universal cost or timeline.
