This is an interesting comment. I expect it's the opposite and he does not want to keep making life decisions just based on the numbers.
Will be interesting to see what Blue Card has to say.
Wish him well, but if you are right, he is cutting off his nose to spite his face.
If part of the complication is bad investments or he can find better opportunity elsewhere, or cash in his chips and give up on investing, then thats a different story. Hopefully thats the case and there is some merit in this move.
If he's just "wiping the slate clean" to get back into similar investments down the track, incurring CGT / sales commissions / stamp duty, that wouldn't be a very smart move at all.
Would be interesting to know more of the facts (if the OP is comfortable sharing).
