About this home

Riverdale

Pass through the private gates and follow the paver drive to this stunning riverfront retreat, where sweeping water views, mature Spanish moss oaks, and a lifestyle most only dream about await. This thoughtfully updated ranch-style home is truly move-in ready. Inside, the expansive great room impresses with skylights, soaring ceilings, and a wall of glass overlooking the river, anchored by a cozy gas fireplace. The open-concept layout flows into a chef's kitchen featuring granite countertops, gas cooking, a large island, upgraded cabinetry, and all new stainless appliances. The primary suite offers a new custom closet and updated bath with a brand new shower. The second suite -- perfect for guests or in-laws -- also features custom closet organization and a full bath. Major systems have been comprehensively updated: new electrical panel, water softener, supply pump, irrigation, and plumbing throughout. Outside, the private dock leads to a covered boathouse with electric lift.

Cost to own

True monthly cost

What this home actually costs per month at the asking price — not just the mortgage.

Principal & interest20% down · 7.4% · 30yr$6,370
Property taxesest. at asking price, St. Johns County$1,530
Estimated total, before insurance$7,900/mo
  • • 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.

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: Metal — year not disclosed (home built 1981)

Roof age drives Florida insurance pricing more than anything else — worth confirming before you offer.

Septic system (public record) · Private well (public record)

County records indicate an onsite septic system — budget a septic inspection before closing (typically $300–$500) and expect pump-outs every 3–5 years.

Source: Florida DOH Water Management Inventory (public record).

Solar potential: ~1,693 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.

Ask about this home

As of July 2026, this Reality Check is informational only — it draws on FEMA/FDEM hazard layers, Florida DOH water records, and the listing’s own fields at this property’s coordinates. 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.

Estimated taxes if purchased at asking price: ~$18,400/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.
