When people ask me "how much does it cost to own a home in South Florida?" they usually expect a simple answer. But the real number is bigger than the mortgage payment, and it catches a lot of buyers off guard. Here is the full picture for 2026.
Why the mortgage is only half the story
Most first-time buyers focus on the principal and interest payment. That makes sense — it is the biggest number on the loan estimate. But in South Florida, the other costs add up fast. Insurance is higher here than almost anywhere else in the country. Property taxes are significant. HOA fees are common. And air conditioning runs year-round.
Let me walk through each cost with real 2026 numbers so you can build a budget that actually works.
Quick example: a $350,000 home in Palm Beach County
With 10% down ($35,000) and a 30-year fixed rate around 6.5-7%, your principal and interest run about $1,900-$2,100 per month. But the total monthly cost — including taxes, insurance, HOA, utilities, and maintenance — lands closer to $3,200-$4,200. That is almost double the P&I payment.
Monthly cost breakdown for 2026
Here is a realistic range for each expense category, based on current market data in Palm Beach County and the surrounding South Florida area. These numbers assume a home in the $300,000-$450,000 range — the sweet spot for many everyday buyers in Delray Beach, Boynton Beach, and Deerfield Beach.
| Expense | Monthly Range |
|---|---|
| Mortgage Payment (P&I) | $1,550-$2,300 |
| Property Taxes | $320-$480 |
| Homeowners Insurance | $375-$580 |
| HOA Fees | $100-$600 |
| Utilities (electric, water, trash, internet) | $250-$365 |
| Maintenance & Repairs (1-2% of home value/year) | $290-$585 |
| Flood Insurance (if in designated zone) | $60-$250 |
| Total Estimated Monthly Cost | $2,945-$5,160 |
Sources: Palm Beach County property appraiser millage rates (18.72 mills combined for 2026), Florida homeowners insurance surveys ($4,500-$7,000+ range for Palm Beach County), EnergySage utility data (~$235/month electricity average), Florida HOA fee surveys ($100-$600+ range), and NFIP flood insurance rate maps. These are estimates — your actual costs will vary by property, location, and coverage choices.
Breaking down each cost
1. Property taxes
Palm Beach County's combined millage rate is about 18.72 mills for 2026, according to the county's approved budget. That works out to roughly 1.7-1.9% of your home's assessed value after the standard $50,000 homestead exemption. On a $350,000 home with homestead exemption, you are looking at about $4,000-$5,500 per year in property taxes — or $330-$460 per month.
One important note: if you buy a home that was previously owned for a long time, the seller's tax bill may be much lower than what you will pay after the purchase. Florida's Save Our Homes cap limits annual increases to 3% for homesteaded properties, but when you buy, the assessment resets to market value. Do not assume the seller's tax amount will carry over.
2. Homeowners insurance
This is the line item that shocks most new buyers. South Florida insurance is expensive compared to the rest of the country. The average Florida homeowners policy costs roughly $4,200 per year — more than double the national average of around $2,000. In Palm Beach County specifically, the average runs about $6,061 per year, according to 2025 rate data.
If you buy a home within 5-10 miles of the coast, expect to pay more. Older roofs, especially those over 10-15 years old, also push premiums up. A wind mitigation inspection can save you money by documenting your roof's ability to withstand hurricane-force winds. Many carriers offer discounts for impact-resistant windows, hurricane shutters, and newer roofs.
3. HOA fees
Not every home in South Florida has an HOA, but many do — especially in planned communities, townhome developments, and condo buildings. For a single-family home in a basic community with minimal amenities, expect $100-$300 per month. For condos or amenity-rich communities with pools, gyms, and gate staff, the range is more like $400-$1,200+ per month.
After the Surfside building collapse in 2021, Florida passed stricter structural integrity and reserve funding requirements for buildings three stories or taller. Older condo buildings may have seen recent fee increases or special assessments to fund reserve studies and necessary repairs. Always ask for the HOA's financial statements and meeting minutes before making an offer.
4. Utilities
Florida's heat and humidity mean your air conditioner runs much of the year. The average electricity bill in Palm Beach County is around $235 per month, according to 2026 EnergySage data. When you add water, sewer, trash pickup, and internet, total utilities typically fall between $250 and $365 per month for a single-family home.
Older homes with less efficient AC units and poor insulation will see higher bills. Newer construction with modern energy-efficient windows and HVAC can bring costs down significantly. A smart thermostat and ceiling fans help, too.
5. Maintenance and repairs
Financial experts recommend setting aside 1% to 2% of your home's value per year for maintenance. On a $350,000 home, that is $3,500-$7,000 annually, or about $290-$585 per month. In Florida's climate, the higher end is more realistic — humidity, bugs, and storm exposure take a toll.
Common Florida maintenance items: AC repair or replacement ($3,000-$8,000), roof repair or replacement ($7,000-$15,000+ for a shingle roof), pressure washing and exterior painting, pest control, landscape upkeep, and hurricane shutter maintenance. Budget for at least one or two large repair items over a 5-year period.
6. Flood insurance
Flood insurance is separate from your homeowners policy. Your lender will require it if the property sits in a Special Flood Hazard Area (SFHA), designated on FEMA's flood maps. National Flood Insurance Program (NFIP) policies average about $800 per year, but rates in higher-risk coastal zones can exceed $3,000 per year.
Even if flood insurance is not required by your lender, it is worth considering. South Florida sees heavy rain events and storm surge risks. About 25% of flood claims come from properties outside high-risk zones, according to FEMA data.
How to build your own budget
Here is a simple process to figure out what you can really afford:
- Start with your monthly income after taxes. Be honest about what you actually bring home.
- Subtract your existing monthly bills. Car payments, student loans, credit cards, groceries, childcare, savings.
- What is left is your housing budget. Aim for no more than 30-35% of gross monthly income for the total housing cost — not just the mortgage.
- Get pre-approved. A lender will tell you the maximum loan you qualify for, but you get to decide what payment actually fits your life.
- Add a cushion. Plan for 10-15% more than your estimate. Things change, insurance goes up, and homes need repairs.
The bottom line
Owning a home in South Florida is absolutely achievable for everyday buyers. But you need to go into it with your eyes open about the full monthly cost. The mortgage payment is the starting point, not the whole picture.
For a home in the $300,000-$450,000 range, plan on a total monthly housing cost of $3,000-$4,500 once you factor in everything. That sounds like a lot, but it includes taxes, insurance, HOA, utilities, and maintenance — things a renter never thinks about.
The good news? Once you know the real numbers, you can make a confident decision. You will not be surprised six months in when the insurance renewal comes or the AC needs a repair. You will already have budgeted for it.
