A $100,000 annual salary gives you solid home-buying power in Florida — but how much house you can afford depends on which county you're targeting, your existing debt load, down payment, and loan program. Furthermore, 2026's interest rates and local property taxes change the calculation significantly from just two years ago. This guide breaks down how much house you can afford in Florida by county, loan type, and debt level.
The DTI Rule: Maximum Mortgage Payment on a $100K Salary
The standard mortgage qualification rule: your total monthly debt payments — including the new mortgage — should not exceed 43–45% of your gross monthly income. On a $100K salary, gross monthly income is $8,333. At 45% DTI, your maximum total debt payment is $3,750/month. If you carry a $400/month car payment and $200/month in credit card minimums, your maximum mortgage payment drops to $3,150/month.
At today's 30-year conventional rate of approximately 6.875%, a $3,150/month principal-and-interest payment supports a loan of roughly $474,000. With 10% down, that translates to a purchase price of approximately $527,000 before accounting for taxes and insurance.
How Property Taxes and Insurance Reduce Your Florida Buying Power
Florida's property taxes and insurance costs significantly reduce real-world buying power compared to the raw payment calculation. In Palm Beach County, annual property taxes on a $500K home average $6,500–$8,000, and insurance runs $3,500–$5,500/year — adding $850–$1,100/month to your total payment. This reduces the affordable purchase price on a $100K income to approximately $380,000–$420,000 in Palm Beach.
Buying Power by Florida County on a $100K Income
Accounting for local taxes and insurance, here's how much house a $100K salary affords across Florida's key markets in 2026: Palm Beach County (Boynton Beach, Lake Worth) — $320,000–$380,000. Broward County (Tamarac, Lauderhill) — $310,000–$360,000. St. Lucie County (Port St. Lucie) — $340,000–$400,000, better buying power due to lower taxes. Miami-Dade (Hialeah, Cutler Bay) — $300,000–$350,000. Martin County (Stuart, Jensen Beach) — $330,000–$380,000.
Stretching Your Budget With FHA, USDA, or Combined Income
FHA financing (580+ FICO, 3.5% down) or USDA $0 down loans in eligible Florida zones can stretch your buying budget by reducing the down payment requirement — freeing cash reserves that improve your qualifying profile. Combining a $100K salary with a partner's income significantly expands buying power in any Florida county.
