Welcome to 309 Arlington, a meticulously maintained home nestled on a quiet cul-de-sac in Patuxent Glen. Since 2019, this home has received a steady stream of thoughtful updates, giving buyers true peace of mind: a renovated kitchen with cabinets updated in 2021, granite countertops, a center island with breakfast bar, stainless steel appliances including a 2021 refrigerator and brand-new 2026 dishwasher, a new disposal, and new kitchen flooring, all set beneath recessed and pendant lighting against a neutral color palette. The spacious primary suite offers a walk-in closet, an en-suite full bath with a new toilet, and a filtered shower head, while the lower level features a new grinder pump, new basement flooring, and new stair carpet; a half bath boasts a new toilet and vanity mirror, and new carpet upstairs, fresh paint, and new ceiling fans in the bedroom and dining room complete the interior. Major systems have been just as well cared for, with a new roof and gutter guards (2022/2023), a radon mitigation system (2019), a new smart thermostat, a new water heater expansion tank, and filtered shower heads in the master and basement baths. Outside, landscaped grounds, a charming front porch, and a tiered deck overlooking preserved land round out this move-in-ready gem - don't miss your chance to own a piece of Patuxent Glen tranquility.
