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). Stairs lead to a 250 SF loft that can be turned into another bedroom, office, or a hangout space. This property is zoned RS-2. Being close to Vilano Beach and the historic district of St. Augustine and the best shopping and restaurants the area has great benefits. NO HOA or CDD fees! This unique home won't last for long!
What to check on this one
- Verify flood zone and elevation certificate—waterfront marsh location requires clarity on AE/VE designation.
- Confirm roof age and condition; 22-year-old roof may need inspection or replacement soon.
- Get 4-point inspection and wind-mitigation report; older home + waterfront = insurer requirements.
- Inspect stilts/foundation and water intrusion history—marsh setting demands structural verification.
- Verify nonconforming third-bedroom and loft legality under RS-2 zoning before relying on room count.
- Review flood insurance costs and availability for waterfront property backing to creek.
Flagged from the listing itself — not an inspection, and no substitute for one. Bring these to the showing.
