I'm going ready to invest a substantial amount of my money in to the market in a modified version of three fund approach, I will likely add a index REIT and index emerging markets to the mix for a total of 5 funds (I'll start a new thread and solicit feedback on my asset allocation when I have it more finalized). I currently have a Schwab account and not a Vanguard account, for ease of use, I would prefer to not have a new account but I have some questions below before making a decision.
For background info, I will be investing enough that I can afford the admiral shares. I will likely lump sum about half the total amount I want to invest and then dollar cost average the rest over a period of 12-24 months (I believe this is not recommended by Bogleheads but I'll feel better not throwing everything in at once).
1. I can buy all the Vanguard Mutual Funds through my Schwab account. Is there any benefit to buying through Vanguard rather than Schwab? It looks like I may have to pay a fee if buying the Vanguard mutual funds through Schwab.
2. I could also buy the Schwab funds (i.e. SWTSX and SWLBX) which look very similar in terms of portfolio and expense ratios. Any reason not to do that?
3. How do Bogleheads thinks of buying the Vanguard ETFs vs Vanguard Mutual Funds? Is there any case when buying the ETFs is preferable? I saw the article from the outgoing Vanguard CIO Gus Sauter which said the majority of his investments were in the ETFs but I wasn't sure why this would be.
4. Any other thoughts/reasons as to which strategy I should use?
Thanks!
