1. After maxing out his IRA contributions annually, what investment strategy would you suggest we pursue for retirement and/or college savings? Where should our money go next? For what it's worth, we're looking at having about $6,000 each month to work with if we do both TIRA and 529s for both kids.
2. We're having a debate on whether we need more in our emergency fund. Would love thoughts on whether it's sufficient or you'd suggest we should save more there and why.
1. After maxing out IRA, I would suggest that you invest in a taxable account in the USA since you still have a valid state address. You may choose Vanguard, Fidelity or discount brokerage firms to invest your money with and you may want to stay away if possible from foreign brokerage firms for various reasons such as high costs, less options, flexibility, etc.
We investigated 529s for our kids when residing abroad but decided not to invest in them, we put our money in a taxable low cost account in the US. Your circumstances may differ.
2. I believe 6 months are the standard but other may offer a better answer to this question.
