<prompt> Human: My son will be in college in 2025. The prepaid tuition cost droped in half this year which is why Im considering it. 27000 lump sum covers tuition and fees for 4 years - which is 25000 now. Tuition inflates at 6 to 9 anually.Putting 27000 lump into a 529 gives me tax-free growth tied to the market and allows for increased spending options. The pre-paid tuition plan insulates me from agressive inflation and is backed by the state. I am strongly leaning towards the pre-paid option, but my research has provided mixed recommendations. Is there anything Im missing? Am I thinking about this correctly? General thoughts rpersonalfinance?  <response>: The 4 year pre-paid option for Florida residents is VERY GOOD at only 27,379.42 for a 4 year degree. Contrast with WA states pre-paid plan, which costs 68,800 for a 4 year degree. I would suggest using the pre-paid plan and taking advantage of the lump sum payment if you can afford it.If you decide to go with the 529 instead of the pre-paid, be aware that Florida does not have a tax deduction available for residents who contribute to a 529 plan. As such, if you decide to use the 529 instead of the pre-paid plan, it behooves you to find the lowest cost 529 out there, as you can invest in any states 529 plan, even if you arent a resident.The lowest cost 529 plan out there is New Yorks 529 which is administered by Vanguard, so you have access to their no-load, low-cost, broad-market index funds and there is only a 25 minimum to start unlike other Vanguard plans, which have a 3,000 minimum.
