Sorry, here is some additional info...
I am married with a 2 year old and another on the way.
My work assignment lasts until September 2019 with the possibility of a few month extension.
I plan to buy a house around $200K with room for improvement, or up to $300K if it really doesn't need work.
I work for the US Gov right now so everything is very stable, but I might leave soon after my assignment is over. That is only if I am able to get a full time job in New York (hudson valley area) where would would like to move to.
We have a net worth of around $750K: $200K in cash right now, and $550K spread around two TSPs, two ROTHs, taxable investments, and a bit in some higher risk startups.
I am 31 and would love to reach FI by my early 40s.
Any other background info? Sorry for not putting it up front.
