Say I'm a federal employee and as far as retirement and healthcare, everything is smooth sailing, I'm well on track to retire comfortably with a pension in lets say 2045. Also consider zero debt, no car payment, and the typical 3-month security fund.
I'm supposed to do some work overseas in the next year, and conservatively I will come back with 50-80k in hand tax-free. During this time I will not hold residence in the US so will not be paying any mortgage or rent during that time.
Question is, if you essentially have this money and no immediate thing to purchase or put money towards, what is the best way to build wealth with that kind of liquidity?
