Price & listing history
Building permits
Comparable recent sales
No closed sales of a similar home within about 10 miles in Nassau County in the last 18 months are in our MLS data set, so this page shows no comparable-sales median or automated estimate for Callahan, FL. A licensed Momentum Realty agent can prepare a property-specific comparative market analysis on request.
The Messtimate
Insufficient local evidence for an automated estimate. The Messtimate is a deliberately simple range — living area × recent closed-sale $/sq ft from comparable homes nearby — and it only renders when at least 3 defensible sales exist within about 10 miles in Nassau County in the last 18 months. None qualify for this home, so no dollar range is shown. It is not an appraisal or a valuation.
Methodology: the range would be 1,881 sq ft × the interquartile $/sq ft of comparable closed sales (same property type, living area within 30%, closed within 18 months, nearest verified subdivision, 3-mile, then 10-mile same-county stage). Estimate for general information only; never an appraisal, valuation, or offer. Updated October 1, 2026.

Buyer research checklist
Items worth confirming for 450402 OLD DIXIE Highway, chosen from what the record shows. This is general guidance, not advice about this specific property.
- New construction: get the builder's warranty terms and the certificate of occupancy in writing, and ask which finishes shown are upgrades.
- The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
- 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 Nassau County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Listed living area is 1,881 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 $3,101/yr) assumes reassessment at the list price; the seller's current bill is not a guide 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 450402 OLD DIXIE Highway and when was it built?
Per the listing record, 450402 OLD DIXIE Highway was built in 2026 and has 1,881 sq ft of living area, 4 bedrooms and 2.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 450402 OLD DIXIE Highway in?
450402 OLD DIXIE Highway is in Callahan, Nassau County. Too few comparable closed sales exist nearby for this page to show local sales statistics; a licensed agent can prepare a comparative market analysis.
Does 450402 OLD DIXIE Highway have an HOA?
The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.
Why might property taxes on 450402 OLD DIXIE Highway differ from the current owner's?
The estimate on this page (about $3,101 per year) assumes reassessment at the list price less the homestead exemption. 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 450402 OLD DIXIE Highway 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.

Opinion & estimate — do not rely on this page. Any figure on this page that is not a verbatim fact from the listing or a public record — including estimated property taxes, insurance, CDD/HOA amounts, mortgage payments, comparable-sales summaries, and market statistics — is an opinion and estimate provided for general informational purposes only. These figures may be inaccurate or out of date, are not appraisals, valuations, or financial, legal, tax, or investment advice, and should not be relied upon. Do not make any purchase, offer, financing, or other decision based on this page. Independently verify everything — price, square footage, lot size, year built, taxes, CDD/HOA, flood status, school assignments, permits, and community rules — with the listing broker, the county, your lender, a licensed inspector, an insurer, and your own advisors before acting.
Estimate methodology. Tax estimates apply county millage to the list price (less the homestead exemption where the parcel is matched to the certified roll) and will differ from the actual assessed bill. Cost and market figures are derived from available data and simple calculations, not a professional appraisal. We make no representation that any estimate reflects fair market value.
