before the below - I take the same approach to taxable as I do with 401k and IRA - MAX IT....
The one mistake I feel I made, was not funding a taxable account sooner; I've maxed 401k's, IRA's --- but did not realize the benefit of a taxable account... I'm currently 51... the "light bulb" moment was around 2013 and I started a taxable with VTSAX and haven't stopped.... it's now over 220k...
I don't know your age, but - the bond allocation for me is way to high from your post.. I'm still 100% stocks, large cap, vtsax, only... I don't care about volatility.. because it's all paid off for me over the years...
as for REIT's -- I used to have them in my ROTH, but - I dropped them for VTSAX (the REIT was also a vanguard fund) - not sure this was the best decision, but - just being transparent.
So, I'm bias ... I want the dividend of a REIT, but I love the growth of a VTSAX... which may yield something close to the REIT div, but not equal or more if you include the growth itself.
My Money is Worth More than Your Money:
https://www.physicianonfire.com/mymoney/ A quote from the pysicianonfire article. "Taxable dollars are like Friday — part weekday, part weekend. You’ve already paid taxes on these dollars once, and the worst you’ll do is pay some tax on the growth of these dollars. At best, “taxable” dollars can be treated the same as Roth dollars."
quote from me "steve, nwoutlier"
taxable dollars grow at the same rate as 401k, roth, etc... you don't pay "taxes" on them until you sell them... but you do pay taxes on dividends -- which I do not consider, because taxes on dividend come out of my ordinary income, not the account itself....
