for $620,000 with 4 bedrooms and 3 full baths, 1 half bath. This 2,744 square foot home was built in 1981 on a lot size of 0.16.
Welcome to 3631 E 133rd Circle - a brick, no-HOA home in Thornton's Summit Grove neighborhood, loved and thoughtfully maintained by the same family for over two decades. With 4 bedrooms and 4 bathrooms across 2,744 square feet, including a functional layout, this home offers the rare everyday comfort that's hard to find. Step outside to a private backyard retreat with a deck and patio, mature perennial gardens, and flowering shrubs that bloom year after year. The perfect space made for morning coffee, weekend gatherings, and quiet evenings outdoors. RV parking and a fully fenced yard (new fence, 2025) add rare flexibility, with dedicated basement storage keeping everything in its place. Inside, two fireplaces anchor the living spaces, and the fully updated kitchen (2023) with a two-sided peninsula, soft-close cabinetry, and new appliances is made for gathering. Recent updates offer real peace of mind: a new Class 4 impact-resistant roof (2024), new furnace (2024), new water main (2024), an updated primary bath with travertine stone, engineered hardwood flooring, and a south-facing driveway that clears itself after a Colorado snow. Set on a quiet street with walking access to parks and trails - including Garfield Park's tennis and roller hockey courts. You're minutes from Trail Winds Recreation Center, the new Anythink Nature Library, the Denver Premium Outlets, Costco, Top Golf, and Chicken N Pickle. Plus walking distance to the two schools in the neighborhood (Tarver Elementary and Fassatti Catholic School). Twenty-two years of memories live here and it's ready for it's next chapter to begin. Down payment assistance and special lender incentive available for qualified buyers! Up to 1% lender credit may be available toward closing costs or interest rate buy-down. Subject to borrower qualification and loan program guidelines.
