3509 Waldorf Drive Rare opportunity on Waldorf Drive, one of the most desirable tree-lined streets in Royal Hills. Situated on a generous 70' x 146' lot and offered at an attractive land-value price, this classic 1950s mid-century ranch presents an exceptional opportunity to renovate, reimagine, or build new in one of North Dallas' most established neighborhoods. The existing home offers the character and proportions of a traditional Dallas ranch, along with several significant improvements made over the years to include; roof installed in 2015, replacement windows in 2017, a Trane 4-ton HVAC system and new garage door and opener in 2019, two sump pumps installed at the east and west front of the home in 2025, and a new water heater with hot-water recirculating pump in 2026. These improvements provide added value and flexibility for buyers who may choose to update and personalize the existing home while preserving its classic mid-century character. Royal Hills is ideally positioned within Dallas' highly regarded private school corridor, inside I-635 and convenient to the Northaven Trail and Dallas North Tollway. The location provides excellent access to many of Dallas' premier private schools, the Medical District, Downtown Dallas, Love Field, DFW International Airport, shopping, dining, and major thoroughfares, all while maintaining the quiet, established residential character that makes the neighborhood so desirable. Whether the vision is to thoughtfully renovate a classic mid-century Dallas ranch or design a new custom residence, this Waldorf Drive property offers a compelling combination of location, lot size, mature surroundings, and long-term potential that is increasingly difficult to find in North Dallas.
