Buying a home in Florida is exciting. But one thing catches a lot of buyers off guard: their property tax bill after closing looks nothing like what it was when the previous owner had the home.

If you've ever wondered why that happens, or what a "TRIM notice" or "escrow shortage" even means, you're in the right place.

Why your taxes will likely go up after you buy

The property taxes listed on a home's current record are often not what you'll actually pay once you own it. In Florida, property is assessed at its just (market) value. But many longtime owners have enjoyed years of tax savings through the Homestead Exemption and the Save Our Homes cap.

When a home sells, those protections don't transfer to you. The property gets reassessed at current market value, and your tax bill resets, often higher than what the seller was paying.

This is the big one to remember: never budget off the seller's tax bill. Budget off what your taxes will be after reassessment. I'll help you estimate the real number before you commit.

Homestead Exemption

If the home is your primary residence, you can file for the Homestead Exemption. It reduces your taxable value and, just as important, it activates the Save Our Homes cap that limits how much your assessed value can rise each year going forward.

File it. It's one of the best tax breaks in the state, and too many new owners forget to.

Save Our Homes cap

Once you have homestead, Save Our Homes caps your assessed value increase at 3% per year or the change in CPI, whichever is lower. That protects you from runaway tax bills as values climb. It's a big deal in a high-growth market like ours.

TRIM notices and escrow

Every August you'll get a TRIM notice (Truth in Millage) showing your proposed taxes. Read it. If your escrow was set up using the old lower tax amount, you can hit an escrow shortage the first year and see your payment jump. Knowing this ahead of time lets us set escrow up realistically from day one.

SW Florida angle

In fast-appreciating spots like Cape Coral, the gap between the seller's old taxes and your new assessed taxes can be significant. This is one of the most common payment surprises I see, and it's completely avoidable. Ask me to run your estimated taxes before you write an offer.
