Yes. Most Miami homes are sold occupied, and it works fine with a few disciplines. Showings run on a schedule you approve, the home stays presentation-ready during the listing window, and personal items, documents, and valuables are secured before the first showing.
The real decisions are around timing your next move. Contract terms can bridge the gap: a closing date aligned with your purchase, a post-closing occupancy agreement that lets you stay briefly after the sale, or a rent-back while your next home is finished. These are negotiated up front, as part of the offer, not improvised at the end.
Rangely coordinates sale and purchase timelines for owners regularly, including the contract language that protects you from being homeless for a week or paying for two homes for a season. Bring the whole timeline to the first conversation and the plan gets built around it.
