Plantation Key mortgage guide: buying in the Village of Islamorada.

Where Plantation Key fits

Plantation Key runs from about mile marker 86 to 91 and is the northernmost of the islands that make up the Village of Islamorada, along with Windley Key and Upper and Lower Matecumbe. Tavernier is just to the north. Because it is inside the village, Islamorada's own land use, permitting and vacation rental rules apply, not Monroe County's.

Canal, bayfront and oceanfront homes

Much of Plantation Key's housing is on canals or the water. The same order works here as anywhere in the Keys: get the elevation certificate, quote wind and flood insurance before you offer, and inspect the seawall and dock. Insurance often decides how much house you qualify for. The canal home guide lists every check.

Flood zones and insurance

FEMA's maps put most of Plantation Key in the AE zone, with VE along open water and some X-zone areas on higher ground. Flood insurance is required on federally backed loans in AE and VE, and lenders may still recommend it in X.

As of October 2026 the National Flood Insurance Program (NFIP) is authorized through December 11, 2026, after a short-term extension Congress passed in September. When NFIP authorization lapses, as it did from October 1 to November 12, 2025, it cannot write new policies, and a closing that depends on a new NFIP policy can stall. Private flood insurance that meets lender requirements is the usual workaround, so on any purchase scheduled near that date, get a private flood quote as a backup.

Rental rules in Islamorada

Islamorada licenses vacation rentals itself, with its own minimum stay, license requirements and limits, separate from the county's program. A license is tied to the property and the rules, not to the listing's past Airbnb history. Before you count on rental income, confirm the license status and transfer rules with the village. Our Keys vacation rental rules guide compares every jurisdiction.

Condos and townhomes

For condos, lenders review the association: reserves, master insurance, owner-occupancy, rental programs and litigation. Buildings that fail Fannie Mae or Freddie Mac review need non-warrantable financing. Screen the building first. See the non-warrantable condo guide.

Loan options on Plantation Key

• Conventional, FHA or VA up to $990,150 for one unit in Monroe County.
• Jumbo above $990,150, common on waterfront homes here.
• Second home, investment or DSCR loans matched to how you will use the home, including no-ratio DSCR options when the rent will not fully cover the payment.
• Non-warrantable condo financing where a building does not pass agency review.

Financing is never guaranteed. Approval depends on you, the property and the lender.
