<p>There’s no limit on the amount that can be rolled over from a UGMA to a student-owned 529. </p>
<p>I’m assuming I’ll pay $25K/year for in-state public schools, and will likely pay this for 5 years rather than 4 given the odds of not finishing in 4. I don’t want to over fund the 529, so I’ll probably stop after it gets close to $75K.</p>
<p>Rather than rolling everything over at once, consider rolling over a fixed amount every month for a year. That’s a more conservative approach, rather than trying to time the market.</p>
