A sell plan for the reasons that you outlined? Oh gawd.

Speaking of Gawd..... Gawd save you from ur lil selfie..

Dude, it is much better to sell some at 23.8% max cap gains tax during current admin OR sell some at 43.4% tax (43.4=39.6+ 3.8 NIIT; plus, maybe even unrealized gains taxes).
Nobody says anything about tomorrow ...3-3.5 years (four would be pushing it into potentially an alternative admin) seem optimal.
I am glad that you are planning so far in advance.
Nothing wrong with that.
