How Much Does It Cost to Live in the Florida Keys?

As of September 2026, Realtor.com reports a $3,700 median monthly rent across Monroe County, while Zillow reports an average rent of about $3,601 per month. Current home prices are also high: Realtor.com reports a $975,000 median sold price countywide, while Redfin reports a median sale price of approximately $971,748 for the three months ending August 2026.

Housing Is Usually the Biggest Expense

For most people moving to the Keys, housing will have the biggest impact on their budget.

Current September 2026 Realtor.com data shows a countywide median listing price of approximately $1.175 million and a median sold price of about $975,000.

Prices vary substantially by community:

These are market medians, not what every property costs. Waterfront homes, newer construction, homes with pools, properties with good boating access, and homes in highly desirable locations can cost considerably more.

For comparison, the U.S. Census Bureau's 2020–2024 data reports a median value of $780,600 for owner-occupied housing units in Monroe County and median gross rent of $1,999. Because those Census figures cover an earlier period and a broader existing housing stock, current listing-market figures are more useful for someone shopping for a home today.

Renting Can Be Expensive

Renting can be a good way to experience the Keys before buying, but current asking rents are high.

Zillow reported an average Monroe County rent of approximately $3,601 per month in August 2026, compared with a national average of $1,948.

Realtor.com's September 2026 data puts the countywide median rent at approximately $3,700 per month.

That means a renter budgeting around $3,500 per month for housing should also plan for:

• Electricity
• Water
• Internet
• Insurance if required by the lease
• Transportation
• Food
• Parking
• Household expenses

And rental availability can be limited depending on the community and time of year.

Buying a Home Comes With More Than a Mortgage

If you're purchasing a home in the Keys, don't calculate affordability based only on the mortgage payment.

Your overall housing expense can include:

Mortgage + property taxes + homeowners insurance + flood insurance + HOA fees + utilities + maintenance + hurricane preparation + waterfront expenses

This is especially important for waterfront properties.

Property Taxes

Florida property taxes vary according to the property's assessed value, exemptions, and local taxing authorities.

For fiscal year 2026, Monroe County's adopted budget shows different millage rates depending on where the property is located. For example, the countywide rate shown in the budget is 2.6929 mills, while the total rate is higher in areas with additional taxing districts and services.

If the home will be your permanent Florida residence, you may qualify for Florida's homestead exemption, which can reduce taxable value by up to $50,000. The property may also qualify for the Save Our Homes assessment limitation.

However, don't assume the seller's current property-tax bill will be your future bill. A change in ownership can result in a reassessment.

Insurance Can Make a Big Difference

Insurance is one of the costs that can surprise people relocating to the Keys.

Monroe County states that all of the county is located in a floodplain, and that flood damage isn't covered by standard homeowners insurance.

That means homeowners may need to consider:

• Homeowners insurance
• Windstorm coverage
• Flood insurance
• Hurricane deductibles
• Additional coverage depending on the property

Monroe County specifically describes flood insurance as a significant component of housing costs and property values in the Keys.

For planning purposes, recent analysis of NFIP data puts the median flood-insurance premium in Monroe County at approximately $1,700 per year, although the actual cost for a particular property can be substantially higher or lower.

The property's:

• Elevation
• Flood characteristics
• Construction
• Location
• Prior claims
• Coverage limits
• Mitigation features

can all affect insurance costs.

Get an actual insurance quote before buying rather than using a countywide estimate to budget.

Food and Everyday Expenses

Everyday goods can also cost more in the Keys because of the geography of the island chain and the distance from major distribution centers.

MIT's 2026 Living Wage Calculator estimates annual food expenses for one adult with no children in Monroe County at approximately $5,340, or about $445 per month. For a household with children, the estimate is substantially higher.

That's a basic-needs estimate rather than a prediction of what an individual household will actually spend.

Your grocery bill will depend on:

• Household size
• Where you shop
• How often you eat out
• Dietary preferences
• Whether you buy locally produced products
• How often you travel to the mainland

Transportation Is Another Consideration

Living in the Keys generally means relying heavily on a vehicle, particularly outside the more walkable areas of Key West.

The Overseas Highway is the primary transportation corridor through the island chain.

That means commuting can be different from mainland living.

For example, someone living in Marathon and working in Key Largo or Key West could face a very different transportation burden from someone who works close to home.

You'll need to budget for:

• Gas
• Vehicle insurance
• Maintenance
• Tires
• Repairs
• Registration
• Potentially longer commutes

If you're moving to the Keys permanently, consider where you work and how often you need to travel off the island chain before choosing a home.

Utilities and Maintenance

Utility costs depend on the property and location, but homeowners should budget for more than the basic electric bill.

Potential expenses include:

• Electricity
• Water
• Sewer
• Internet
• Trash
• Landscaping
• Pest control
• Pool maintenance
• HVAC maintenance

A waterfront property can have additional expenses such as:

• Seawall maintenance
• Dock maintenance
• Boat-lift maintenance
• Corrosion-related repairs
• Exterior painting
• Storm preparation

Salt air and tropical weather can be hard on buildings and outdoor equipment.

The Cost of Living Depends on Your Lifestyle

Two people can live in the Florida Keys and have completely different monthly budgets.

A renter living simply

Someone renting a modest property, cooking at home and working locally may have a relatively controlled budget, but housing will still be a major expense.

A homeowner

A homeowner needs to add:

• Mortgage
• Property taxes
• Insurance
• Flood insurance
• Maintenance
• Utilities

A waterfront homeowner

The budget can increase further because of:

• Seawall
• Dock
• Boat lift
• Pool
• Landscaping
• Boat ownership
• Higher insurance considerations

A retiree or second-home owner

Someone who doesn't commute every day may spend less on transportation but potentially more on:

• Dining
• Boating
• Travel
• Recreation
• Property maintenance
• Home services

What Should You Budget Before Moving?

A person considering a permanent move should calculate their total monthly cost, rather than looking only at rent or mortgage.

For example:

If Renting

• Rent
• Electricity
• Water/sewer
• Internet
• Transportation
• Food
• Insurance
• Other living expenses

If Buying

• Mortgage
• Property taxes
• Homeowners insurance
• Flood insurance
• HOA
• Utilities
• Maintenance
• Transportation
• Food
• Emergency reserve

For a Keys homeowner, I'd also keep a separate reserve for unexpected hurricane, storm, seawall, roof, plumbing and HVAC expenses.

Is the Florida Keys Cost of Living Worth It?

That's ultimately a personal decision, but the important thing is to understand what you're paying for.

People who choose the Keys may be paying a premium for a particular lifestyle:

• Boating
• Fishing
• Warm weather
• Waterfront living
• Outdoor recreation
• Island communities
• Proximity to the ocean
• The ability to spend more time outdoors

But the tradeoff is that housing, insurance and certain everyday costs can be substantially higher than in many mainland communities.

The best way to determine whether you can comfortably afford the Keys is to calculate the complete cost of living for the specific community and property you're considering, rather than relying on a single countywide average.
