What Your Key Biscayne Home Could Rent For

Right now, houses and townhomes in Key Biscayne are asking a median $18,500 a month and condos and apartments $8,950, across 169 active rentals. Leases signed in the last 90 days closed at a median $15,000 and $7,000. 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 lease that follows Florida law, and condo and HOA expertise, including the association application when your community requires one.

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.

What Leases Fastest in Key Biscayne

The quickest leases on Key Biscayne are houses near the K-8 school and the parks, rented on annual terms to families relocating to Miami, and they tend to go in late spring and summer ahead of the school year. Condos lease quickly when they are furnished, renovated and in a building with a straightforward tenant approval. What sits is an unrenovated apartment priced off the rent of a renovated one, or a unit in a building whose approval takes weeks. Present a Key Biscayne rental clean, photograph the view and the amenities, and have the association application ready to hand the tenant on the day they apply.

Annual or Seasonal for a Key Biscayne Owner

Choosing between an annual and a seasonal lease on Key Biscayne depends first on the building and the village. Many associations set a minimum lease term and limit how often a unit can be leased in a year, and short stays need a state licence and tourist-tax registration as well. Where a seasonal lease is allowed, a furnished oceanfront condo can earn a strong rent for the winter months, then sit empty through summer and hurricane season unless a second tenant is found. An annual tenant brings steadier income and less wear, and suits houses more than apartments. Price both against real Key Biscayne leases, counting furniture, cleaning and utilities, before you decide.

Rules a Key Biscayne Landlord Checks First

Before a Key Biscayne owner advertises a rental, check the rules that sit above the lease. The association's documents decide whether you can lease at all, the minimum term, how many leases a year are allowed, the application fee and the tenant screening, and board approval can take weeks. The village's own rules on lease length apply on top of that, so ask the village before you market a short stay, which also needs a state licence and tourist-tax registration. For a house with a pool or a dock, set out in writing who maintains them and who handles hurricane preparation. Florida's security deposit law applies to every Key Biscayne lease, so hold and return the deposit as it requires.

Houses and townhomes in Key Biscayne are asking a median $18,500 a month and condos and apartments $8,950, from live BeachesMLS rentals updated daily. The right rent for your home depends on its size, condition, furnishing and exact location; request a free rental analysis and we will price it from the closest comparable leases.
Do you already have a tenant looking for a property like mine in Key Biscayne?
We may. Renters who work with BreakThru Realty tell us the area, the budget, the home type, the furnishing and the move date they need, and we keep those requests on file. When you ask for a rental strategy, an agent checks your property against them before the call and tells you what the records show. A potential match is an introduction, not a signed lease, and nothing about your property reaches a renter until you agree.
Do you offer property management in Key Biscayne?
Yes. You can lease your Key Biscayne home with us and manage it yourself, or add full management and hand us the day to day as well. Ask for a quote for either service.
How do you screen tenants?
Credit history, verified income, criminal background, eviction history, prior landlord references and identity verification. We also manage the condo or HOA application when your community requires one.
What does Florida law require for a security deposit?
A landlord must tell the tenant in writing, within 30 days of receiving the deposit, how and where it is held. After the tenant moves out, the landlord has 15 days to return it if there is no claim, or 30 days to send written notice of a claim against it. This is a summary, not legal advice.
