About this home

Rivertown Springs

Lot 80 - The Topaz combines timeless Low Country charm with modern comfort in a thoughtfully designed 4-bedroom, 3.5-bath layout with a spacious 3-car garage. The welcoming foyer opens to an airy great room that flows into the dining area and extended covered lanai, creating a bright, open space for entertaining or everyday living. The chef-inspired kitchen features a large island, morning kitchen, and walk-in pantry. Tucked at the rear, the owner's suite offers a peaceful retreat, while two secondary bedrooms share a private hallway. A fourth bedroom with garage entry adds flexibility for guests or multigenerational living. A study in lieu of a flex room provides a private office or creative space. Bath 2's shower in lieu of a tub adds a spa-like touch. RiverTown, along the St. Johns River, offers parks, lakes, preserves, and scenic trails for active Northeast Florida living.

• 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: Shingle — year not disclosed (home built 2026)

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

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.
