I'm going to join you.
I am at $846,400 right now*. In the next 6 months, I will have ~$140K of income (gross), but then on 7/1/18, the firehose of cash will stop, as I am retiring.
Not quite sure what my taxes will look like, and, of course, like you said, who knows what the markets will do!!
Good luck to us both!
* actually, my spreadsheets say $832,400, but I have been lowballing the value of my home, at $306,000. Even increasing that value to $320,000 is still conservative, so I'll go with that, which brings my NW up to $846,400.
