About this home
St. Augustine
Sometimes you find a home and immediately feel the WOW factor! 18 Althea is one of those homes, nestled in the wooded marsh in the Fullerwood neighborhood of St. Augustine. Built on stilts, the 2,223 SF property sits on .67 of an acre, backing to Robinson Creek. Imagine taking your paddle board or kayak to the intracoastal waterway. The builder spared no detail, importing materials to create a serene retreat like no other. An extended paver driveway leads to a covered parking area and storage, perfect for vehicles, water toys and supplies. Upstairs, the wrap-around porch is welcoming with a bar for seating. Through the double doors, the open-concept great room/dining and kitchen combination is perfect for entertaining. High ceilings are covered in wood. The main floor of the house includes TWO primary suites with large closets and ''matching bathrooms,'' plus a third room with double doors, currently being shown as a bedroom (nonconforming).

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, SilverLeaf, eTown…), bond assessments are collected on the property-tax bill — the tax estimate above reflects county averages, so confirm this home’s exact CDD with us.
- • 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.

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.

Storms & insurance
Florida Reality Check
The storm-and-insurance facts every Florida buyer should know up front.
Zone AE — high-risk flood zone (Special Flood Hazard Area)
Lenders require flood insurance for financed purchases here.
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 2004)
Roof age drives Florida insurance pricing more than anything else — worth confirming before you offer.
Sewer · FL0021938 - City of Saint Augustine WWTP - customer accounts · Public water (record)
County records show this parcel on central sewer served by FL0021938 - City of Saint Augustine WWTP - customer accounts — no septic system to inspect or maintain.
Source: Florida DOH Water Management Inventory (public record).
Solar potential: ~1,767 usable sun-hours per year
A strong solar roof by Florida standards — worth pricing panels if energy bills matter to you.
