Your Florida Mortgage Costs $1,100 More Than Zillow Says
Your Florida Mortgage Costs $1,100 More Than Zillow Says
A couple from up north found their dream home in Florida, ran it through Zillow, and saw a payment around twenty one hundred a month. Their real payment was over three thousand. That is more than a thousand dollars a month they never budgeted for, and not one cent of it had to do with their interest rate.
If you are planning a move to Florida right now, that gap is the single most expensive thing you do not know yet. By the end of this post, you are going to know exactly where it hides.
My name is Emmett Dempsey. I have been originating loans since 2007. Through the crash, through the recovery, through COVID, through the rate spike. I have been in it the whole way. And here is what I have watched change. The calls keep coming from out of state. People retiring south. People chasing no state income tax and a backyard they can use in January. Good credit, good income, ready to go.
The number one thing they get wrong is the same thing every time. They are using an online calculator that was never built for Florida.
Why Online Calculators Get Florida Wrong
Your principal and interest is just the loan itself, the part that pays back what you borrowed plus the rate. That number is math, and it is the same in every state. Zillow gets that part basically right.
What Zillow does not know is everything stacked on top of it. In Florida, the stuff on top is not small anymore. So let me walk you through it, piece by piece, the way I would across my desk.
Cost #1: Home Insurance (The One That Hurts Most)
Start with the one that hurts the most. Home insurance.
If you are coming from a state where you paid maybe twelve or fifteen hundred dollars a year to insure your house, I need you to throw that number out completely. Florida is the most expensive state in the country for homeowners insurance, full stop. We are talking multiples of what most of the country pays. On a mid range home, a real Florida policy can run several thousand dollars a year, and on the coast it climbs from there.
There is some good news baked into 2026, and I want to be fair about it. The market has actually started to settle. After some legal reforms, lawsuits dropped hard, a few carriers came back, and the state backed insurer even cut its rates for a lot of folks this year. The panic years are easing.
But settling down is not the same as cheap. Florida is still the priciest insurance state in the nation, and that is not changing this year.
Here is the part that trips people up. A national calculator drops in some average insurance number from across the whole country. That number is a fantasy here.
When a lender hands you a payment, the very first thing you do is ask them: is that a real Florida quote on this exact address, or a national average? Those two numbers are not even in the same area code.
Cost #2: Property Taxes (The Year-One Ambush)
Now the one that quietly ambushes people in year one. Property taxes.
Florida has something called the Homestead Exemption. In plain terms, it knocks part of your home's value off the books before they calculate your tax, and it locks in a cap so your assessment cannot jump more than a few percent a year no matter how hot the market gets. Floridians call that cap Save Our Homes. It is a genuinely great benefit, and it is one of the real reasons people love owning here.
Here is the catch nobody from out of state sees coming. You do not get it automatically when you buy. You have to file for it, and you file by March first of the year after you close. Picture closing in October. You are not filing until the following March, and the savings do not kick in until that next tax year.
Which means in year one, you are taxed on the full value with no exemption and no cap. And here is where it gets really sneaky. That seller you are buying from may have owned the place fifteen years. Their Save Our Homes cap held their taxes down the whole time, so the tax figure on the listing looks low and friendly. Yours will not look like theirs. Your bill resets to current value.
So the move here is simple. When you get your estimate, ask your lender point blank: are you running my taxes at the non homesteaded rate for year one? If they pause, that is your answer, and that is a problem. You can read more about how property taxes factor into closing and ongoing costs through the CFPB's homeowner resources.
This whole homestead thing is worth watching closely right now, because Florida voters are deciding this November on a much bigger exemption that could phase in over the next couple of years. The exact rules and the timing deadlines on that are still moving, and they are exactly the kind of thing you want pinned to your specific situation rather than guessed at from a blog.
Cost #3: Flood Insurance (The One Almost Nobody Checks)
Here is the piece almost nobody checks before they fall in love with a house. Flood.
Flood insurance is separate from your regular homeowners policy. Regular insurance does not cover rising water, period. And if your home sits in what FEMA calls a high risk flood zone, your lender will require a flood policy. That is not a maybe. That is a requirement before you can close.
Here is the thing that catches people. The flood zone is attached to the land, not the house. You can get fully pre approved, fall completely in love, and never hear the word flood until the file is deep in process and somebody finally pulls the zone. By then you are emotionally all in on a house that just got several hundred dollars a month more expensive.
The fix is to know the zone before you make the offer, not after. The federal flood map from FEMA is public and free. You punch in the address and it tells you. If it comes back high risk, you budget that policy in from the start. Before the offer. Not after the contract.
The Full Stack: Where the $1,100 Gap Comes From
The individual numbers are one thing, but it is the stack that shocks people.
Take that same home our northern couple found. Here is how the real payment builds:
Principal and interest — the Zillow number, which looked totally reasonable to them
Real Florida insurance — an actual quote on the exact address, not a national average
Year-one property taxes — at the full non homesteaded rate
Flood insurance — if the property needs it
HOA dues — the monthly fees a huge number of Florida neighborhoods carry
You stack those four extra things on a payment that looked affordable, and you land a thousand dollars or more above where they started. That is the gap. That is the whole thing in one sentence. It was never a mortgage problem. It was a Florida information problem, and it is completely avoidable if you get the real number before you sign anything.
Who Really Needs to Hear This
If you are relocating from a state where the cost of owning was steady and predictable, this is you. If you are retiring on a fixed income where the monthly number actually has to work, this is not optional. And if you are buying your first home anywhere in Florida, you need these costs in front of you before you start shopping, not after. The National Association of Realtors tracks how relocation patterns keep pushing buyers into states like Florida, which makes running real numbers more important than ever.
Who can breathe a little easier? If you are looking at a newer inland home, well away from the coast, sitting above the flood line, in a neighborhood with no HOA, you are going to see the friendlier end of all these numbers. But you still have to check the specific address. A calculator has no idea what your exact street costs to insure. I do. That is the whole job.
The Bottom Line on Moving to Florida
Florida still makes a ton of sense. No state income tax, real long term appreciation, and plenty of areas that give you the same ocean and the same weather as the famous expensive zip codes at a fraction of the price. The math can absolutely work. It just has to be the real math.
Frequently Asked Questions
Why is my Florida mortgage payment higher than the Zillow estimate?
Online calculators get principal and interest right, but they miss the costs stacked on top. Real Florida homeowners insurance, year-one property taxes at the non-homesteaded rate, flood insurance, and HOA dues can add a thousand dollars or more a month. None of it has anything to do with your interest rate.
How does the Homestead Exemption and Save Our Homes cap work?
The Homestead Exemption knocks part of your home's value off before taxes are calculated, and the Save Our Homes cap limits how much your assessment can rise each year. You do not get either automatically. You have to file by March first of the year after you close, so in year one you are taxed on full value with no cap.
Do I need flood insurance in Florida?
If your home sits in a FEMA-designated high-risk flood zone, your lender will require a flood policy before you can close. Regular homeowners insurance does not cover rising water. The flood zone is tied to the land, so check the address on the free FEMA flood map before you make an offer.
Is Florida homeowners insurance getting cheaper in 2026?
The market has started to settle after legal reforms reduced lawsuits and brought a few carriers back. The state-backed insurer even cut rates for many homeowners. But settling down is not the same as cheap. Florida remains the most expensive insurance state in the country.
How can I get an accurate Florida mortgage payment estimate?
Ask your lender to run a real insurance quote on the exact address, calculate taxes at the non-homesteaded rate for year one, check the FEMA flood zone, and add any HOA dues. That gives you the true monthly payment instead of a national-average guess.
