Your St. Lucie County property appraiser value isn't your sale price. Here's why.

What do just, assessed and taxable value mean on your St. Lucie County record?

Every January 1, the St. Lucie County Property Appraiser estimates a just value for each parcel in the county. Florida's rules then turn that into the numbers your tax bill is built on. Here is how a long-time homestead can end up with three very different figures:

You can see all three for your own parcel in the property search at paslc.gov. The gap between just value and assessed value is your Save Our Homes savings. It stays with the home only while you own it.

Why is the appraiser's value lower, or higher, than what homes are selling for?

• The date. Just value is set as of January 1. Anything the market did after that, up or down, shows up a year later. St. Lucie County's single-family median has moved between $388,000 and $407,000 in the 13 months to September 2026, so on most homes the date alone moves the number by thousands.
• The method. The appraiser values every home in the county with the same models, mostly without going inside. A new roof, an updated kitchen, a pool, deferred repairs or a busy road can each move one home's sale price in ways a countywide model can miss.
• The costs of selling. Florida law tells the appraiser to account for the usual costs and fees of a sale (s. 193.011(8)). For the 2026 roll, the St. Lucie County Property Appraiser reported a 15% adjustment to recorded sale prices for every property type (form DR-493, signed June 24, 2026), which is a large part of why just values sit below sale prices.
• Save Our Homes. A homestead's assessed value can rise at most 3% a year, or less when inflation is lower (2.7% for 2026). After 10 or 15 years, assessed value can be a fraction of just value.

None of these numbers sets your price. Buyers and their lenders look at what homes like yours sold for recently and what they can buy instead today. That is why a written value from the closest sales matters before you list, and before you decide not to.

What happens to the taxes when you sell, and when you buy?

The Save Our Homes savings do not pass to the buyer. On January 1 after a sale, the home's assessed value resets to its just value, so the buyer's bill is usually higher than yours, and the listing can no longer show your low tax bill as a guide (from February 1, 2027, the current owner's taxes may not appear in printed listing materials, s. 689.261).

If you are buying another Florida homestead, portability can move up to $500,000 of your Save Our Homes savings to the new home. Since July 1, 2026 the savings can come from any Florida homestead you had in the prior 3 years. You must own and live in the new home on January 1 and file with the property appraiser by March 1.

What does Amendment 3 change for St. Lucie County homeowners in 2027?

Amendment 3 passed on November 3, 2026 with about 62% of the vote (unofficial results; it needed 60%). For homesteads it raises the exemption on non-school taxes to $150,000 in 2027 and $250,000 in 2028, then indexes it to inflation. School taxes keep the $25,000 exemption. Homes without a homestead get a 5% yearly cap on assessment increases instead of 10%. Homestead owners who did not have a Florida permanent residence on December 31, 2026 get $25,000 off school taxes and $50,000 off other taxes for the first four years of exemption; residency is the property appraiser's call.

These figures use the 2026 proposed rates, the most recent the appraiser publishes; the final 2026 rates can only be the same or lower. They hold those rates steady for 2027 and 2028. Cities, the county and special districts set new rates every year, and the Florida Association of Counties estimated St. Lucie County government revenue would fall by $66.7 million under the 2027 exemption and $112.5 million under 2028's, so rates may rise to make up some of it. Read 2027 and 2028 as estimates. Moving here from another state? The newcomer side of this is in moving to Port St. Lucie.

When does the appraiser send values, and how do you disagree with one?

The appraiser mails the Notice of Proposed Property Taxes (the TRIM notice) in August, with the just, assessed and taxable values and the proposed rates. If you think the just value is wrong, start by calling the appraiser's office: many questions are settled informally. A formal petition goes to the St. Lucie County Value Adjustment Board, filed within 25 days of the TRIM notice's mailing date (s. 194.011). Tax bills follow in November, with a 4% discount for paying that month.

A note on what helps: the board looks at market value as of January 1, so evidence means sales of similar homes around that date, not this month's listings.

How do you find out what your home would actually sell for?

From the sales most like it. Brent Sharp prepares a free written Sharp Number from 3 closed sales and 3 active listings near your home, adjusted for the differences buyers pay for: size, condition, roof age, pool, lot, flood zone, and HOA or CDD fees. It is the method he used on more than 12,000 valuations for lenders, servicers and investors, written up for a homeowner instead. It is a broker's opinion of value, not an appraisal, and there is no obligation to list.

What moves value on Port St. Lucie homes in particular (canals without ocean access, septic vs. sewer, roof age) is in the Port St. Lucie home value guide. Weighing a cash offer against listing? See cash offer or list it.
