I would refrain from buying the house until 2-3 years into the transition and after you reach a point where you are cash flow positive in your new life. Ditto about the car loans if they are low interest rate ( < 3%). In short put the 1M aside and try to do the switch as if you did not have the money. You should be able to make the switch without the $1M subsidizing the switch (except for subsidizing your monthly cashflow for the first year or so).
