Why Key Biscayne Ambassador matters

The Ambassador is a 1975 building with 89 residences on Crandon Boulevard, the main road of Key Biscayne.

Key Biscayne

Key Biscayne is a barrier island village connected to the mainland by the Rickenbacker Causeway, a toll road that crosses Virginia Key. Crandon Boulevard runs the length of the island. Crandon Park, with its beach, is at the north end and Bill Baggs Cape Florida State Park, with the Cape Florida lighthouse, is at the south end. The village center, with its shops, restaurants and services, sits between them.

The island has beach access, parks and a short drive to Brickell and Downtown. The Ambassador is in flood zone AE.

Architecture and unit composition

The building is a 1975 condominium of 89 residences. It is styled Key Bisc Ambassador Condo. It rises nine floors and is not a low-rise.

Inspect the specific unit and ask for the floor plan.

Building operations

Ask the association for the current service list and what the monthly charges include.

Florida's milestone inspection and structural integrity reserve study rules apply to condominium buildings of three or more stories; ask for the inspection report, the reserve study and any assessment history. Ask also for the reserve funding, the current budget and financial statements, any special assessments approved or under discussion, and the master insurance coverage and deductible.

Policy framework

Policies, fees and applications, including pet, rental and minimum-lease rules, are set by the association and should be confirmed at offer stage.

Sales context

One recorded sale, March 2026, at $720,000. It is one sale, not a building price. Pricing depends on floor, view, size, condition and the assessment picture.

Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you're buying at Key Biscayne Ambassador

Underwrite the building, then the unit. Reserve study, inspection results and assessments come first. Get them before you commit.

Price the flood and insurance exposure. The building is in zone AE. Get the master policy and your own quote early.

Confirm size and layout. Get the plan and the association's schedule.

What to know if you're selling at Key Biscayne Ambassador

Lead with documents. Current budget, reserve study, inspection status and financials shorten buyer diligence.

Price against your line and condition. Use recent trades in comparable size and renovation level, not the building's highest sale.

Recorded sales history

Recorded transfers for this building in Miami-Dade County public records, back to Oct 1975. Prices reflect the recorded consideration; transfers the Property Appraiser does not qualify as arms-length are shown unmarked. Nominal-consideration paper transfers (deeds into trusts and LLCs, estate and family transfers, corrective deeds) are part of the record but not sales, and are omitted from this table. Recording lags closing, so the newest sales can take several weeks to appear.

Figures are reported as recorded and may be updated as the county updates its records. This page is informational and is not an offer or solicitation. Apartment estimates are automated, from public records, and are not appraisals.
