Scott,
Thanks for your many articles on personal finance. I've been an avid reader for several years.
Why not start SS as early as possible (age 62), when the repayment option allows a restart at a later age (assuming you can afford it) and I can keep more money in my IRA hopefully earning 8%? I did a simple spreadsheet that shows that with an 8% return, starting at 62 gives a higher total return than starting at 66 up to age 90. Seems like its a can't lose approach, as long as I have enough money for the repayment, if needed.
Thanks,
Skip
