Property taxes
✓ Certified tax roll · county-average rateProperty taxes in Florida are reassessed after a sale, so a buyer’s first full-year bill can be higher than the seller’s. Budget from this estimate, not the current bill, before you make an offer.
The current owner’s taxable value is below today’s asking price; after a sale the assessment is set from market value, so the estimated bill is higher. Exemptions and portability can reduce it.

What it really costs to own 300 Se 5Th Avenue #4140
The parts of the monthly number a mortgage calculator leaves out, from this listing's MLS record, the county tax roll, Citizens and FEMA. Property facts only.
| Property tax | The current owner's bill is about $30,325/yr (certified county roll, taxable value × millage). Buy at the asking price of $3,995,000 and the first-year bill resets to about $73,850/yr (the parcel is matched to the certified roll; asking price less the $50,000 homestead exemption × 18.72 mills (county-average millage, estimate)); Save Our Homes caps later increases at 3%/yr. |
|---|---|
| HOA dues | $4,030/month per the listing record. Dues cover what the association documents say they cover; ask for the budget and reserve study before you close. |
| Home and flood insurance | The average Citizens Property Insurance premium in Palm Beach County is $1,753/yr (18,387 policies, Citizens detail by county, April 2026); private-market quotes differ by roof age, wind mitigation and distance to the coast. The page's modeled range for this home is $17,500–$36,500/yr; neither is a quote. Flood: this address maps to FEMA zone X, outside the high-risk zone; flood insurance is optional but most lenders and insurers recommend it. Statewide, a zone X flood policy runs about $500–$700/yr (FEMA Risk Rating 2.0 averages, not a quote). |
| Roof and age | Built in 1989. An original roof would be about 37 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report and ask for the roof permit date. |
Estimated carrying cost at the asking price, before the mortgage: about $10,330/month (tax $6,154, HOA $4,030, insurance $146). An estimate from the sources above, not a quote; the monthly-cost calculator on this page adds the loan.
Flood zone & elevation
Sourced environmental data for the parcel. Confirm with FEMA and your insurer.
From the FEMA National Flood Hazard Layer. In this zone lender-required flood insurance is generally not mandated; confirm for the parcel.
Approximate parcel elevation from USGS; confirm exact elevation with a survey.
Palm Beach County is on the Florida coast; wind coverage is a major part of the premium. Premiums and coverage vary by home (roof age, wind mitigation, claims history); obtain a quote from a licensed insurer.

Comparable recent sales
6 closed sales in MIZNER TOWER CONDO in the last 18 months — same property type, living area within 30% of this home. Sold prices are MLS closed-sale records, deemed reliable but not guaranteed.
Median of these 6 sales: $2,885,000 ($1129/sq ft). Stronger local evidence. Shown for general reference only — not an appraisal or a statement of this home’s value.
The Messtimate
Our automated estimate of the likely sale-price range for this home — modeled from recent closed sales nearby adjusted to today's market, a local size-and-age model, and the county tax roll. It is an estimate, not an appraisal, not market value, and not an offer. A licensed agent's CMA sees the condition, the lot, and the live market that a model can't.
Strong local evidence — built from 7 comparable closed sales in MIZNER TOWER CONDO (same property type, closed within the last 18 months, each adjusted to today's market); the Palm Beach County 2025 tax roll just value ($1,620,000) × the local sale-to-roll ratio of 40 nearby sales.
Track record: across 2,975 recent closed sales we scored, the closed price landed inside the Messtimate range 57% of the time; median miss 9.6% (closed sales statewide, FL + GA feeds that permit an automated estimate). Re-scored weekly; last 2026-10-14.
Actual list price: $3,995,000 ($1,570/sq ft) — the seller's asking price is not an input to this range; compare the two.
A 50% spread on the same house — here is what a model can't see:
- Condition & updates — a 1989 home may have had its roof, kitchen, or HVAC replaced since, or not; the model can't see either.
- The lot — this listing is waterfront; water frontage is priced far off nearby averages.
- Carrying costs & concessions — this home carries HOA dues of $4,030/mo; insurance, CDD/HOA and seller-paid buydowns change what a buyer actually pays.
And what the live market is doing right now:
- 4945 active listings competing, 1381 under contract

Buyer research checklist
Items worth confirming for 300 SE 5th Avenue #4140, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 1989 (37 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
- Condominium: request the association's budget, reserves, the most recent milestone or structural inspection report, and two years of meeting minutes before relying on the dues.
- FEMA flood zone X: flood insurance is not usually required, but get a quote anyway — FEMA reports roughly one in four flood claims come from outside high-risk zones.
- Get a homeowners insurance quote for this specific address in Palm Beach County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
- Listed living area is 2,544 sq ft: verify it against the property appraiser's record and measure before relying on it.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $73,850/yr) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $43,525 more per year than the current owner’s estimated bill (+144%). Exemptions and portability change the actual bill — confirm with the county property appraiser.
- School zoning shown here comes from district data and changes; confirm the assigned schools directly with the district before relying on them.

Frequently asked questions
How big is 300 SE 5th Avenue #4140 and when was it built?
Per the listing record, 300 SE 5th Avenue #4140 was built in 1989 and has 2,544 sq ft of living area, 3 bedrooms and 4.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 300 SE 5th Avenue #4140 in?
300 SE 5th Avenue #4140 is in Mizner Tower Condo in Boca Raton, Palm Beach County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 300 SE 5th Avenue #4140 have an HOA, and how much are the dues?
The listing reports HOA dues of $4,030 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
Why might property taxes on 300 SE 5th Avenue #4140 differ from the current owner's?
The estimate on this page (about $73,850 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $43,525 more per year than the current owner’s estimated bill (+144%). Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 300 SE 5th Avenue #4140 in a flood zone?
The FEMA flood map places this parcel in Zone X, outside the special flood hazard area, so flood insurance is not usually required by a lender. It is still available and worth quoting; confirm the parcel's status with FEMA and your insurer.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
