I'm currently maxing my 401(k) and a Roth IRA. I have emergency savings, savings for a house down payment, and savings for vehicle maintenance. I'm looking for advice on how to properly build a taxable portfolio of Vanguard ETFs to supplement my retirement savings.
I've read that total market ETFs are the most tax efficient investment for a taxable portfolio, so I plan to buy 1 share each of VTI and VXUS every two weeks. I chose these ETFS because the Boglehead's wiki's Lazy Portfolio page recommended them, but also because I do not have the required cash to invest in fractional shares of their equivalent mutual funds.
I am 30 years old. When I begin shifting my allocation to include more fixed income products, I will include them in my 401(k) and IRA accounts. Please assume that I will re-balance all of my investments as I build my taxable portfolio (i.e., I will buy fewer equity mutual funds in my tax-protected accounts as I accrue more equity ETFs in my taxable account until I reach the desired allocation across all portfolios).
Please critique this strategy for building a taxable portfolio (e.g., unanticipated tax implications, making purchases too often, etc).
