Why Key Townhouse matters
Key Townhouse is a 10-unit, two-story condominium from 1966. Ten homes share a low-rise property.
Key Biscayne and Sunrise Drive
Key Biscayne is a barrier island reached by the Rickenbacker Causeway from Brickell and Downtown Miami, about a 15-minute drive without traffic. It is an incorporated village with its own government, a single main road, Crandon Boulevard, and a residential grid of low-rise condominiums, single-family streets and a small village center. Sunrise Drive is one of the village's residential streets.
The island's anchors are public. Crandon Park, on the north end, has a beach, a marina and a tennis center. Bill Baggs Cape Florida State Park, at the south end, has the lighthouse, trails and a beach. The Village Green is the civic and recreation space in the middle of the village, with a playground, a community center and events. The village center along Crandon Boulevard has the grocery, restaurants, bike shops and services.
The island has beach and boating access and is a short drive to Brickell by the Rickenbacker Causeway.
Architecture and unit composition
The building has two stories and 10 units, built in 1966. Ask the association for the size schedule and the recorded plans.
Parking is on site: assigned spaces, guest parking and a garage. Ask which units have a garage space.
Building operations
Ask whether the association owns any dock or beach access, or whether residents use public facilities.
Florida's milestone inspection and structural integrity reserve study rules apply to condominium buildings of three or more stories. This building has two stories; ask whether it falls under the rules, and ask for any inspection report, reserve study and assessment history. Also ask for the current budget and monthly charges, financial statements, any special assessment notices and the master insurance policy. The property is in FEMA flood zone AE, so ask about flood coverage on the master policy and what the owner must carry.
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. Confirm leasing and pet rules with the association.
Sales context
One recorded sale, October 2024, at $538,500. It is one sale, not a building price.
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 Townhouse
Get the unit's size and layout in writing. Ask whether the unit is one or two levels.
Review structural and reserve documents. Confirm inspection status, reserves and any planned assessment before you price.
Check flood and wind insurance. The building is in flood zone AE. A quote for the unit before contract will show the real carrying cost.
Confirm leasing and pet rules. They are set by the association.
What to know if you're selling at Key Townhouse
Price against comparable low-rise units on Key Biscayne, not the island's larger waterfront towers.
Have the documents ready. A current budget, reserve documents and the association's estoppel shorten diligence.

Recorded sales history
Recorded transfers for this building in Miami-Dade County public records, back to Nov 1979. 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.
