Description

Tucked on a quiet court in Twin Creeks South Estates, this beautifully updated home sits on a rare, flat third of an acre — and the space opens up possibilities in every direction. Inside, original hardwood floors and thoughtful upgrades set a warm tone throughout. The kitchen is built for real life: a stainless gas range, soft-close cabinetry, touch-sensor faucet — and a window above the sink that frames your own backyard garden, because even meal prep deserves a view. Bathrooms have been tastefully...Tucked on a quiet court in Twin Creeks South Estates, this beautifully updated home sits on a rare, flat third of an acre — and the space opens up possibilities in every direction. Inside, original hardwood floors and thoughtful upgrades set a warm tone throughout. The kitchen is built for real life: a stainless gas range, soft-close cabinetry, touch-sensor faucet — and a window above the sink that frames your own backyard garden, because even meal prep deserves a view. Bathrooms have been tastefully updated, and the primary bedroom features a custom Elfa closet system that brings order and elegance to your everyday routine. And what a backyard. Rose beds, grapevines, fig and apple trees, a culinary herb garden, greenhouse, paver patio, outdoor kitchen, and mature shade trees — it's less a yard and more a private retreat. Morning sun, afternoon shade, room to grow, and space to entertain effortlessly. The lot itself is the bonus: flat, level, and large enough to dream — ADU, pool, sport court, or a custom sanctuary tailored entirely to you. Top-rated schools — including an elementary school just over a half mile away, a walkable six years of morning routines — lush parks, everyday convenience, and HOA dues of just $30/month. Welcome home.
