The short version: When you buy a house in Florida, the low property tax bill the seller was paying does not transfer to you. Their number was held down by the Save Our Homes cap, sometimes for years. The county resets the assessed value to market price the year after the sale, so your bill starts fresh, and it is usually higher than what the listing or the seller told you they pay.
This is the single most common tax surprise I see with Brevard buyers, and it is almost always avoidable. A few minutes of math up front beats a January shock.
What Save Our Homes actually does
Florida has a rule called Save Our Homes. Once a property has a homestead exemption, the county can only raise its assessed value by a capped amount each year, no matter how fast the market climbs. The cap is the lesser of 3 percent or the change in the national Consumer Price Index. For 2026 that figure is 2.7 percent.
Sounds small. Over ten or fifteen years it is not. A house someone bought in 2010 might be worth $400,000 today but still be assessed at $220,000, because the cap held the taxable value down year after year while prices ran away from it. The owner pays tax on the lower number. That gap is the whole game.
Why the number resets when you buy
Save Our Homes protects the owner, not the house. When the property changes hands, the protection ends. Under Florida Statute 193.155, the county reassesses to full market value on the January 1 after the sale, and your homestead cap starts over from that new, higher base.
So the low figure you saw is a snapshot of the seller's history with the home, not a preview of yours. Depending on how long they held it, your first full-year bill can be noticeably higher, and in long-held homes it can run well above what the seller was paying.
A side-by-side, with real Brevard-ish numbers
Say you buy a Palm Bay home for $360,000. The seller owned it for twelve years and their assessed value sat at $210,000. Rough picture, using a combined millage near the Brevard average (verify the exact rate for your parcel with BCPAO):
- What the seller pays: tax on about $185,000 after their homestead exemption, on roughly a 1.4 percent combined rate, lands near $2,600 a year.
- What you will pay: the value resets to the $360,000 market price. After your own homestead exemption, you are taxed on about $335,000, which at the same rate is closer to $4,700 a year.
Same house, same street, nearly double the bill. Nothing went wrong. The cap simply reset. Treat the seller's tax line on the MLS as trivia, not a budget.
How to protect yourself before you close
- Ignore the seller's current bill. Estimate your own on the purchase price, not the old assessed value. BCPAO publishes a tax estimator that does this for you at our property tax tool.
- File your homestead exemption. If the home is your primary residence, filing knocks up to $50,000 off the taxable value and starts your own Save Our Homes cap for future years. The deadline is March 1, and it is free through BCPAO. Do not pay a service for this.
- Ask about the CDD. In parts of Viera and other master-planned areas, a Community Development District fee rides on the same tax bill and has nothing to do with Save Our Homes. Know it before you offer.
One thing worth watching: the homestead exemption itself may change. On the November ballot, Florida voters decide whether to raise it, which would lower the taxable base for homesteaded owners. I walked through the mechanics in this post on the November amendment. It is not law yet, so plan around today's roughly $50,000 exemption and treat any increase as a bonus if it passes.
None of this is a reason not to buy. It is a reason to buy with the right number in your head. If you want, send me the address you are considering and I will run the realistic reset figure for you, no obligation, before you write an offer. Text me at (321) 576-2239.
