I’m a little confused. Are you saying your older kid submitted a Profile three years ago and never has needed to update it?
The equity in your primary residence has increased. The amount you are contributing to tax deferred retirement accounts is added back in as income so if that has increased, that would add more to your costs. Your mortgage amount doesn’t matter…it’s the equity in your home.
But really…could you explain how your first kid has never needed to update his Profile?
You have your first kid’s Profile. Are the numbers on it the same? If not, that’s part of the issue you are seeing.
