Thank you all so much for your comments and for the spirited discussion about Swensen's opinions of the TREA. I am pretty comfortable with my plan because it very much makes sense to me and it seems as though it is reasonable to others as well. For now, at least, I will continue on this path and consider going up a bit in TREA as time goes on. In the meantime, I will be buying much CREF stock "on sale" because it is 80% of my portfolio. A small value tilt is something I will certainly consider in the future—after I do much more homework.
You are a great bunch. Keep up the good work.
