The first ad for lot sales appeared in the Dallas Morning News, offering 100 front foot lots in “the Residence Show Grounds of Texas.” Lot prices ranged from $10-$30 per foot. The Flippen-Prather Company bought an additional 44 acres along Turtle Creek, south of renamed Highland Park Lake. Armstrong offered 100 acres west of Preston Road to the Texas Presbyterian University, an opportunity that would unfortunately never come to fruition.
