Do I pay a fee to rent a home in Key Biscayne through BreakThru Realty?

In most South Florida rentals the landlord pays the agent commission, so working with a BreakThru rental agent costs a renter nothing. If a specific listing works differently, we tell you before you tour it.

What do I need to apply for a rental in Key Biscayne?

Most landlords ask for a government-issued photo ID, recent pay stubs or an offer letter showing income of roughly three times the monthly rent, recent bank statements, a credit report and rental references. Having these ready before you tour lets you apply the same day.

How long does rental approval take in Key Biscayne?

Landlord approval usually takes one to three business days. If the home is in a condo or HOA community, which is common in Key Biscayne, the association runs its own application and approval, and that can take two to four weeks in many buildings. We start the association paperwork the moment you are accepted.

Can I rent a pet-friendly home in Key Biscayne?

Yes. The pet-friendly page lists every current Key Biscayne rental whose listing says pets are allowed. Most still set limits, such as breed or size restrictions, a maximum number of pets and a pet fee or deposit, and condo associations often add rules of their own, so we confirm the policy for your pet before you apply.

Are there seasonal rentals in Key Biscayne?

Yes. Furnished homes and condos in Key Biscayne are let by the month or the season, with the strongest demand from January through April. Seasonal rents run higher than annual leases and the best winter rentals book months ahead, so start early; the seasonal and furnished pages show what is available now.

Renting in Key Biscayne

The Key Biscayne rental market has two sides. Houses and larger condos lease on annual terms to tenants relocating to Miami who want the beaches, the parks and Key Biscayne K-8 Center close by. Furnished condos in the oceanfront buildings lease for the winter season or by the month, subject to each association's rules on lease length and tenant approval. Many buildings approve tenants before a lease can start, so renters with their application documents ready do best.

Houses, Condos and Apartments

Rentals in Key Biscayne range from studio apartments to furnished estate homes. The market table on this page splits the median rent between houses and townhomes on one side and condos and apartments on the other, because the two markets price very differently, and the pages below narrow the search by home type, monthly rent, furnishing, pets and lease length.

How Renting With BreakThru Works

Tell us your budget, move-in date and must-haves, and a licensed rental agent builds a shortlist, schedules tours and helps you apply with a complete file. In most South Florida rentals the landlord pays the agent commission, so our help costs a renter nothing.

Own 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.
