Direct answer

Not necessarily. The answer depends on whether you qualify while carrying the current mortgage, how sale proceeds affect the down payment and reserves, and what the builder contract requires. A bridge loan, home-equity option, or later sale may be possible for an eligible borrower.

The plan should address timing, temporary housing, overlapping payments, market risk, and what happens if the current home does not sell on schedule.

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.
