<prompt> Human: My eldest will be entering college in 2 years and my youngest will be entering college in 6 years. College costs approximately 100,000.00. My plan is to have 50,000.00 saved for the eldest and pay the rest out of pocket. I have 2 options with the youngest. I could put 900.00 per month into a 529 Plan and have around 60,000.00 saved for when he enters college. Or I could put that 900.00 per month into the principle of my mortgage and have my house paid off just as my youngest enters college. I wouldnt have money saved for her but the money I was putting towards my mortgage could be put towards her college. Also, based on my calculations I would save about 20,000.00 in interest payments by paying off my house early, which is 1 year of college. What should I doplay it safe and just put the 900.00 into a 529 or go for paying my house off and not have anything saved for college  <response>: Pay off the house. Kids can get their own loans for college. Plus, you can then help them out to the best of your ability.
