Q. Upon retirement, I want to take a mixed withdrawal. I would like to take partial withdrawal ($50,000), sign up for monthly withdrawals, and possibly buy a TSP annuity. Is it possible to hold off buying the annuity when the interest rate is better? I was under the impression that one had to make and take all of these options up front. Otherwise, you lock yourself out of making/buying any other options TSP withdrawal has to offer.
A. Once you begin a full withdrawal, you lose the option to buy a TSP annuity at a later date.
