What Your Key Biscayne Home Could Rent For

Right now, houses and townhomes in Key Biscayne are asking a median $19,450 a month and condos and apartments $8,000, across 173 active rentals. Leases signed in the last 90 days closed at a median $17,500 and $6,600. Your rent depends on size, condition, furnishing and location, so we price your home from the comparable leases closest to it, not from a citywide average.

Renting Out a Home in Key Biscayne

Key Biscayne landlords choose between an annual tenant and a furnished seasonal lease, and in the condo buildings the association often decides: many boards approve every tenant, and some set a minimum lease length or limit how often a unit can be leased. For a house, the choices are whether to lease furnished, who looks after the pool, garden and dock, and how the lease handles hurricane preparation. We check your building's rules first, then price your home from live Key Biscayne rents.

Leasing Services

Rental pricing from real comparable leases, marketing to every agent and portal in South Florida, thorough tenant screening, a Florida-compliant lease, and condo and HOA expertise, including the association application when your community requires one.

Optional Full Property Management

Prefer not to be the landlord day to day? Beyond finding the tenant, we offer optional full management of your Key Biscayne rental, end to end. Ask for a quote for either service.

Florida Rules Every Landlord Should Know

Florida law requires a landlord to tell the tenant in writing, within 30 days of receiving a security deposit, how and where it is held. After the tenant moves out, the landlord has 15 days to return the deposit if there is no claim against it, or 30 days to send written notice of a claim. Condo and HOA communities often add leasing rules of their own, such as minimum lease terms and a tenant application. This is a summary, not legal advice.
