Florida Voters Are About to Give Homeowners a $250,000 Tax Exemption — Investors Could Get Stuck With the $12 Billion Bill

Florida just voted to cut homeowner taxes to almost nothing. If you own rental property there, that's not good news — it's a bill with your name on it.

On June 2, 2026, the Florida Legislature passed HJR 1F, "Save Our Homes From Excessive Property Taxes," now Amendment 3 on the November 3 ballot. It cleared the House 75-26 and the Senate 30-9, and it needs 60% voter approval to become law. Every headline about it says the same thing: massive tax relief for homeowners. Almost none of them mention what happens to the other side of the ledger.

Here's why this matters right now, not after the election. The same bill that guts homestead property tax bills also rewrites the rules for every property that isn't someone's primary residence — rentals, short-term rentals, second homes, commercial buildings. Non-homestead owners already generate 64% of Florida's property tax revenue. When the state's own economists say this amendment costs $12 billion a year by year five, that money doesn't vanish. It gets found. And there's only one property class left standing when the homestead exemption swallows most of the tax base.

If you own — or are underwriting — Florida rental property, you need to understand this bill before November, not after your 2027 tax notice shows up.

Two Different Tax Systems, One Bill

Amendment 3 does two things, and investors need to track both separately.

For homesteaded owner-occupants, the non-school property tax exemption jumps from $50,000 to $150,000 in 2027, then to $250,000 in 2028, with inflation adjustments starting in 2029. The bill also directs future legislatures to build a path toward eliminating non-school homestead property taxes entirely — no firm date yet, but the intent is on record. Roughly 60% of Florida's homesteaded owners would owe close to nothing outside their school levy.

For everyone else — landlords, commercial owners, vacation-home owners — the annual cap on assessed-value growth drops from a maximum of 10% to 5%, starting January 1, 2027. Taken alone, that's actually a win: it slows how fast your taxable value can climb in a hot market, which is real protection against a repeat of the appreciation spikes investors saw in 2021-2022.

But that protection comes bundled with exposure. The assessed-value cap limits how fast your value grows — it does nothing to stop a county from raising the millage rate applied to that value. And Florida's Revenue Estimating Conference has already put a number on how badly counties will need to do exactly that: roughly $5 billion in lost revenue in year one, $8.8 billion in year two, climbing to $12 billion recurring by year five. The Florida Association of Counties estimates the $250,000 exemption alone costs counties $4.8 billion annually, and is on record calling the amendment a "tax shift" that "makes Florida more unaffordable." Gov. DeSantis, who originally pushed for an even broader version of this plan, has since distanced himself from the Legislature's final draft, telling reporters at a June 29 bill signing in Tampa, "what the Legislature did wasn't my proposal." When the governor who wanted the tax cut won't fully own the bill that delivers it, that's a signal the mechanics are messier than the ballot title suggests.

The Numbers

• HJR 1F / Amendment 3 passed the Florida House 75-26 and Senate 30-9 on June 2, 2026; needs 60% voter approval on the November 3, 2026 ballot to take effect January 1, 2027.
• Homestead exemption: $50,000 today → $150,000 (2027) → $250,000 (2028) → inflation-indexed from 2029.
• Non-homestead assessment cap: cut from 10%/year to 5%/year starting 2027 — applies to rentals, commercial property, second homes.
• Fiscal impact (Florida Legislature's Office of Economic and Demographic Research): ~$5B lost revenue in year one, ~$8.8B in year two, ~$12B recurring annually by year five.
• Florida Association of Counties: the $250,000 exemption alone costs counties an estimated $4.8B/year; counties call it a "tax shift."
• 64% of Florida's current property tax revenue already comes from non-homestead properties, according to state distribution data — meaning the tax base counties will lean on for the shortfall is the same base that's about to get squeezed harder.
• 900,000+ Florida renters are already classified as cost-burdened, spending 40%+ of income on rent — the population most exposed if landlords pass increases through.
• Ken Johnson, chair of real estate at the University of Mississippi, put the mechanism bluntly: "Local governments could raise the [tax] rates on those landlords, which in turn will raise the rents."
• The Florida Apartment Association, representing roughly 80% of the state's apartment units, has publicly flagged concern that reform "not create unintended consequences for renters and housing providers."

Common Mistakes Investors Make Here

• Reading "tax cut" headlines and assuming it applies to you. If the property isn't your homestead, this bill's relief provisions don't touch your bill at all — only the assessment cap section does, and that's a different mechanism with a different risk profile.
• Panic-selling Florida rentals over rate-hike fear. The 10%-to-5% assessment cap cut is a real benefit — slower taxable-value growth is good for you. Don't let millage-rate anxiety cancel out a provision that's actually in your favor. Run both effects together before deciding anything.
• Ignoring county-level variation. A $12B statewide number hides huge differences — a county with a small homestead share and diversified sales-tax revenue absorbs this very differently than a county that's mostly retirees in homesteaded houses. Treat every county as its own underwriting question.
• Waiting for the November election to start modeling. The vote outcome changes if this happens, not when you should start planning. Counties are already running their own fiscal projections. You should be too, especially on anything you're underwriting to close in Q4 2026 or 2027.

How to Use PropGPT for This

"Pull the current millage rate and assessed value history for [county/address] in Florida, then estimate my 2027 property tax bill under an 8% millage rate increase and a 15% increase, assuming the 5% non-homestead assessment cap applies." This gives you a real range instead of a headline — the two scenarios bracket what a county under fiscal pressure is likely to do.

"Compare my rental property's taxable value growth under a 10% annual cap versus a 5% cap over the next 5 years, starting from today's assessed value of $[X]." Quantifies the one part of this bill that actually helps you, so you're not overreacting to the millage-rate risk without crediting the offset.

"Screen my current Florida rental portfolio for properties where market value has pulled significantly ahead of assessed value — flag the ones most exposed to a catch-up reassessment once the new cap takes effect." Identifies which specific holdings carry the most latent tax risk, rather than treating your whole portfolio as equally exposed.

"Find Florida counties where property tax makes up more than 80% of general fund revenue versus counties under 60%, and rank them by dependency on non-homestead property tax collections." Surfaces which markets have other revenue levers to pull (sales tax, tourism tax, growth) and which will lean hardest on landlords — a factor worth weighing before your next Florida acquisition.

"Model my DSCR loan cash flow on a $[purchase price] Florida rental at [rate]% interest under 0%, 8%, and 15% property tax increase scenarios — at what tax level does my deal go cash-flow negative?" Turns an abstract policy risk into the one number that actually matters: your breakeven point.

The Bottom Line

Amendment 3 is being marketed as a homeowner tax cut, and for roughly 60% of Florida's homesteaded owners, that's exactly what it is. But real estate investors don't get to read the ballot summary and move on — you have to read the mechanism. A state that's about to zero out taxes on most primary residences still needs the money to run schools, police, and roads, and the only tax base left standing is the one you're sitting on.

That doesn't mean sell your Florida rentals. It means underwrite this like the live variable it is: model the millage-rate downside, credit yourself the assessment-cap upside, and treat county selection as a bigger part of your Florida strategy than it's ever been. The investors who run these numbers before November 3 will be negotiating from data. Everyone else will be reacting to their next tax notice.
