So I have three kids. The oldest is two years away from high school and the second oldest is fours years away. We think they are going to go to a private high school. I do have a large savings now that is kind of my emergency/big purchase fund...I might be making some additions to our home, and replacing an AC (Big Purchase) this spring. So I don't mind having that big savings even though everyone says that I should have less cash. Regardless, I was thinking of how can I prepare for High School costs for both of them. So the question is, can I put away some of that money and use it in a 529 to pay for high school? Perhaps a CD or Muni Bond and not pay taxes. I don't want to put it into anything risky, but looking for a way to 1) Earmark the money 2) earn a savings of 3-5% 3) not pay taxes. Could I do that with a 529 for them? Or is there another way? Maybe buy a MUNI BOnd that expires around then and not pay taxes? Does this make sense? Or do I just keep my money in a 2.5% savings and keep adding it to it. I should also add that I am maxing my 401K, and I do have percentage of money in Stocks/REITS. Maybe 75% in cash 25 % in Stocks/Reits TAXABLE ACCOUNTS. Not going to focus on college in this question...this is HIGH SCHOOL (short term ) for now. Thank you.
