Local amenities
Grassy Key sits in the middle of the Florida Keys, a stretch known for water access, fishing and a relaxed island pace. This page does not list specific nearby hospitals, shops, schools or parks, so buyers should confirm the closest services with the sales team and on a visit.
The oceanfront setting is the main draw here, with the homes positioned along the Overseas Highway corridor that links the Keys.
Getting around
The address is on Overseas Highway (US-1), the main road running the length of the Florida Keys and the primary route to neighbouring islands and the mainland. Most daily trips here are by car. Buyers should confirm drive times to services and airports with the builder rather than rely on estimates.

Buying pre-construction at SeaGlass Cove
Buying a new home in Florida usually starts with registering your interest so the sales team can share availability, pricing and floor plans. Deposits are often staged over time, with an initial amount at signing and further instalments before closing. The builder will confirm the exact structure for SeaGlass Cove.
Because construction here is complete, buyers are looking at finished homes, so the interim occupancy phase common to condo projects is generally less of a factor. Closing timelines are set out in the purchase agreement.
Florida's 15-day rescission period under FS 718.503 covers new condominiums only, so it does not automatically apply to single-family homes. Have a real estate lawyer review any contract. Buying early in a release can mean a wider choice of residences, but this is not a guarantee of future value.
