Re: what price would you sell at?

Back of the envelop: Bonds are paying about 0% real, E10/P is what now about 4%? So want to compare to a real return of 3% I might get from reinvesting the funds. So $3-ish million. If I thought I could get 6% real from reinvestment I would say $1.5M. This is optimistic at best so likely too low in ...

Re: What's your number?

We are at 11x expenses right now at age 36/35. We realize we have a long ways to go to get 40x, but the more we save and the less we spend on fixed costs will allow us to get to that target.

Re: Another take on the "rebalancing bonus"
