sdrealtor, your #3 should have the age of mid/late 20’s. 2 Full time engineers or nurses should easily have HH income of $150k by the time they’re 26-27, if they graduated around 22 yrs. of age. For RN who go straight into 2 yr. RN program after HS and graduate at 20, they should be making around $75k each by the time they’re 25.
