18571 Buena Vista Avenue Tucked beyond a long private drive, 18571 Buena Vista is a rare offering that blends privacy, scale, and modern updates in the heart of Yorba Linda. This stately 4-bedroom, 3-bathroom residence spans approximately 3, 096 square feet and includes a spacious upstairs bonus room with wet bar- ideal for a media lounge, game room, or home office retreat. A dramatic two-story entry, vaulted ceilings, and a sweeping curved staircase create an elegant first impression, while extensive 2025 upgrades enhance comfort and style throughout. Recent improvements include a full interior and exterior repaint, wide-plank luxury vinyl flooring, upgraded baseboards, new carpet, designer lighting, and refreshed bathrooms with new fixtures, mirrors, and hardware. The kitchen has been thoughtfully updated with new stainless steel appliances, tile backsplash, and modern hardware. Additional highlights include new closet doors, exterior lighting, attic storage, and fresh landscaping with new sod. Major system updates provide added value and peace of mind: a full PEX repipe (2024), newer windows (approx. 8 years old), updated HVAC (approx. 8 years), and roof replacement (approx. 6 years). Termite clearance completed in 2025. The expansive lot offers ample opportunity for outdoor living- perfect for a future pool, ADU, sport court, or serene garden retreat. Although the driveway is technically part of this parcel, there is a recorded easement for the adjacent home, and both properties share responsibility for its maintenance. This turnkey home delivers a rare combination of seclusion, versatility, and move-in-ready condition- an exceptional find in today’s market.
