Well my number for being rich is anything 6,000,000 USD+
I would allocate these assets the following way:
3,000,000 - Income Producing Investments
2,000,000 - Home
1,000,000 - Everything Else
In addition to that 6 million USD net worth this assumes 0 debt and other income such as salary or business that it is 200K USD+ per year.
That is naturally applicable to Seattle area in other areas home value could be less, etc.
And yes I do get your point that you don't need a huge house or fancy car, but the scenario above is what it takes to not feel the need and live fairly modestly in Seattle area.
Would that be modest living there? Here, that is pretty extreme!
Well, considering that $1,780,000 buys you this in our bearish real estate market:
