Can someone help me clarify something? The first 3 funds listed each have an opening balance of $3k. So if I wanted to do something like the 60/40 split mentioned in the OP, I would have to pony up $6k to start both of those funds?
Also, when I click on the funds it tells me they are available as an ETF. These do not have an opening balance requirement and seem to have lower expense ratio. Obviously I have no idea what an ETF is (and yes, I know what the acronym stands for but that doesn't really clarify anything) and how it compares to the versions linked in the OP.
Deciding to get serious about investing since my (very small) 401k from my previous employer was moved to a terrible company (Total IRA) that is charging me fees for not meeting their $50k minimum balance.
Buying ETFs is fine as an alternative if you don't meet minimum balances. The main knock against ETFs is that buying and selling them is more complicated.
You can also get a 65:35 split with a single fund using Vanguard's LifeStrategy Moderate Growth. That will also give you international diversification and you will not have to do any rebalancing.
