One thing to consider, which might be an issue for you (as it is for me - not working/trying to be ``retired``), is that my understanding is that any contributions to an IRA must be against earnings (work income) in that taxable year. In other words, if you aren`t working, you cannot contribute. If you do have earnings, they must be more than the amount you contribute (up to the limit). Best talk to you`re CPA if this issue is in play.
FWIW,
