Start of 5-yr wait

[Guest hellas]

I've had an IRA for 5 yrs. If I convert to Roth and want to withdraw $$$ under special provisions (say school, or 1st time house buying), do I have to wait another 5-yrs from date of conversion?

If yes, is it more beneficial to stay in IRA and be able to redeem a.s.a. needed, although having to pay taxes on redemption?

The five years starts at conversion.
