Cost to own
True monthly cost
What this home actually costs per month at the asking price — not just the mortgage.
- • Homeowners insurance is on top — in Florida it varies widely with roof age and wind/flood zone (see the Reality Check below). Budget it before you offer.
- • In CDD communities (Nocatee, eTown, Seven Pines…), bond assessments are collected on the property-tax bill, and the amount varies home to home — a prior owner may have prepaid the bond — so we confirm this home’s exact line rather than trust a community average.
- • Taxes are estimated at YOUR purchase price — Florida assessments reset on sale, so the seller’s current bill is usually lower than yours will be (that applies to the reference bill above too).

Storms & insurance
Florida Reality Check
The storm-and-insurance facts every Florida buyer should know up front.
Zone X — minimal flood hazard
Flood insurance is typically not required by lenders (always optional).
Flood damage is not covered by standard homeowners insurance — it’s always a separate policy.
Hurricane evacuation zone A
Zone A evacuates first in a storm — typically coastal and surge-prone areas.
Roof: Shingle — year not disclosed (home built 2007)
Roof age drives Florida insurance pricing more than anything else — worth confirming before you offer.
Sewer · St Johns County Utilities - accounts · Public water · St Johns County Utilities - water accounts
County records show this parcel on central sewer served by St Johns County Utilities - accounts — no septic system to inspect or maintain.
Source: Florida DOH Water Management Inventory (public record).
Solar potential: ~1,777 usable sun-hours per year
A strong solar roof by Florida standards — worth pricing panels if energy bills matter to you.
Krista can connect you with local insurance quotes before you make an offer.
As of September 2026, this Reality Check is informational only — it draws on FEMA/FDEM hazard layers, Florida DOH water records, and the listing’s own fields, read at the listing’s map pin or, on lots of an acre or more, across the county parcel (state cadastral). A zone shown for part of a lot may not be where the home stands. None of it is a determination, survey, or inspection, and public records can lag or conflict with on-site conditions. Independently verify anything you’ll rely on: the flood zone at msc.fema.gov and floridadisaster.org/knowyourzone (and confirm flood-insurance cost with your lender and a licensed insurance agent), and the sewer/septic, roof, and utilities with a professional inspection.

Taxes & assessment
2025 property taxes (current owner): $15,297/yr
Estimated taxes if purchased at asking price: ~$35,100/yr
Florida’s Save Our Homes cap limits how fast the current owner’s assessment can rise — and it resets when a home sells, so a buyer’s tax bill is typically based on the purchase price, not the seller’s bill above. Estimate uses the median effective rate across 1,595 current St. Johns listings and includes typical non-ad-valorem assessments; actual taxes depend on exemptions and taxing district.
