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. 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.
What the ratio leaves out in Florida
Debt-to-income math assumes your escrow is predictable. In Florida it often is not.
Insurance premiums have moved sharply since 2022. A renewal can add two hundred dollars a month to a payment that qualified comfortably a year earlier.
Condo dues carry the same risk. A special assessment after a milestone inspection is not part of your ratio at closing. But it is very much part of your budget afterwards.
Leave headroom. Qualifying at the maximum is a different thing from affording it.
Where the down payment changes the answer
On a $100,000 salary, moving from 5% down to 10% does two things at once.
It cuts the loan, which lowers principal and interest. It also lowers or removes the mortgage insurance premium, which is a separate saving.
Together those can lift your comfortable price range more than a quarter-point rate improvement would. Model both on the affordability calculator.
If the cash is not there, Hometown Heroes and other Florida assistance can supply part of it.
Front-end and back-end ratios
Lenders look at two numbers. The housing payment against income, and total debt against income.
Conventional guidance runs roughly 28% and 45%, though strong files stretch further.
FHA is more generous on both, which is why it approves buyers conventional declines.
In Florida the front-end ratio is where insurance does its damage, since it sits inside the housing payment.
Run both on the debt-to-income calculator with a real insurance quote.
What a $100,000 salary actually buys
It depends far more on your other debts than on the rate.
A car payment of $600 removes roughly $90,000 of purchase power at current rates.
Student loans in repayment do the same in proportion.
Clearing one installment loan before applying often moves your range more than waiting for rates to fall.
Property taxes reset when you buy
The seller's tax bill reflects their homestead exemption and Save Our Homes cap.
Neither transfers to you. The county reassesses at your purchase price.
That reassessment often raises the bill by thousands. Budget the non-homestead figure, then file for homestead by March 1 of the following year.
Before you shop
Clear one installment loan if you can, get an insurance quote. Run the real numbers on the affordability calculator.
A realistic range
On $100,000 with modest debts, most Florida buyers land between $340,000 and $420,000.
Heavy car or student debt pulls that down sharply. So does a high-premium coastal address.
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.
