I am going to keep my corporate job for another 4 yrs
I don't like those situations. People are overdressed and overhoused, and there's an Establishment that goes along with the mores of making payments on a "standard" 30-year home mortgage.
At the same time, you can't easily bale on a situation like that, and go out on your own even if you are, nominally, quite wealthy. There are too many strings they pull up in the cutthroat corporate hierarchy to make sure that doesn't ever happen and if it does you won't be successful at it.
