A $100,000 salary buys real house in Florida. How much depends on the county, the debt you carry, your down payment, and your loan program. And 2026 rates plus local property taxes have shifted the math a lot from 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 basic rule: your total monthly debt, new mortgage included, should stay under 43 to 45% of gross monthly income. On a $100K salary that gross is $8,333 a month. At 45% DTI, your ceiling for all debt is $3,750. Carry a $400 car payment and $200 in credit card minimums, and your mortgage payment room drops to $3,150.
At today's 30-year conventional rate near 6.875%, a $3,150 principal-and-interest payment supports a loan around $474,000. Put 10% down and that is roughly a $527,000 purchase price, before taxes and insurance enter the picture.
How Property Taxes and Insurance Reduce Your Florida Buying Power
Here is where Florida bites. Taxes and insurance pull your real buying power well below the raw payment math. In Palm Beach County, property taxes on a $500K home run $6,500 to $8,000 a year, and insurance adds another $3,500 to $5,500. That is $850 to $1,100 a month on top of principal and interest. It drags the affordable price on a $100K income down to roughly $380,000 to $420,000 in Palm Beach.
Buying Power by Florida County on a $100K Income
Once you fold in local taxes and insurance, a $100K salary lands differently across Florida in 2026. Palm Beach County (Boynton Beach, Lake Worth) comes in at $320,000 to $380,000. Broward County (Tamarac, Lauderhill) runs $310,000 to $360,000. St. Lucie County (Port St. Lucie) stretches to $340,000 to $400,000 thanks to lower taxes. Miami-Dade (Hialeah, Cutler Bay) sits at $300,000 to $350,000. Martin County (Stuart, Jensen Beach) lands around $330,000 to $380,000.
Stretching Your Budget With FHA, USDA, or Combined Income
FHA (580-plus FICO, 3.5% down) or a USDA zero-down loan in an eligible zone can stretch your budget. Shrinking the down payment leaves more cash in reserve and strengthens your file. Pair that $100K salary with a partner's income and your buying power jumps in any county.
