About this home

TERRIFIC PRICE for a new 1-story on 5,000 square foot lot. Per builder, cost to replace would be $100,000 for the lot, $220-235K for construction = $320-335K total cost. That makes this purchase unimaginably well priced! Stunning new construction just minutes to the Med Center and Downtown via 288. Home is inside the loop, with EZ ingress onto Hwy. 288 going North or South. Beautiful finishes adorn this custom spec with a vaulted ceiling in the living room and an open floor plan. Huge Primary bedroom suite with spacious bath and lots of closet space! The kitchen has an island and is open to the Dining Room and Living Room for maximum enjoyment! Home is wired for Smart features. Builder is installing 4 cameras -- in and out. You will fall in love at the price point for this terrific home. And yes, there's a back yard too!
