https://www.bogleheads.org/wiki/FidelityI have my portfolio with Fido, taxable/IRAs, with a lazy 3 fund setup with the bonds/REIT held in deferred accounts and FSKAX is all the taxable contains (I turned off reinvesting and use the dividends/cap gains as spending/expenses).
I use a mix of:
Fidelity Total Market Index Fund (FSKAX)
Fidelity ZERO Total Market Index Fund (FZROX) is newer than when I'd started, but is literally a zero fund and good option for FSKAX at this timeFidelity Real Estate Index Fund (FSRNX)
Fidelity U.S. Bond Index Fund (FXNAX)
I have maybe 1% in silly/sentimental funds that should be sold but likely won't as they aren't hurting anything really (just stating it for the record).
So my husband is also not real interested in more than the absolute basics, so this is what I've got set up, and he can figure out if something were to happen to me.
1. Taxable account throws off a good amount to cover about half our expenses because we don't reinvest dividends/cap gains. He can check in April and December each year and sweep the money into the savings account (already connected to said account, walked him through it on the website and it is really simple, but it's likely an easy phone call to any rep - "how much cash is in there? Okay now can you transfer it to the BANK name account, or walk me through how to do it on my own?" and they'll do so.
2. inherited IRA (which likely is not going to be repeatable since the #@$! jerkwad SECURE bill was passed*) has automatic required minimum distributions already in place. Can also make sure to set them up for your own IRAs. Automatically sells off whatever funds in whatever percentages you specify on whatever date you'd like. Can set it up to do so monthly even if you like the idea of monthly "income" to sweep over into the taxable and then refer to 1 above about how to get cash from taxable to your local checking/savings account.
3. Something super $ pops up and need extra? Figure out if it's better to draw out of an IRA (since he's already 70 and you're over 59, you can draw from any source penalty free, and may be better to start depleting the IRAs due to the SECURE act). Tell him to sell "X" fund in X account if you need more money for some reason. Can again show him how to do so online (and then once cash is settled, then do #1 sweep cash to where needed). Again, can just leave him basic instructions and he can call rep and have them walk him through it on his own or they may be able to execute the sells/moves.
* This means no more stretch IRAs and you definitely need to see about depleting your IRAs at this point so your heirs aren't smacked with a "must remove all $ in 10 years" amount that causes a huge tax nightmare for them.
Between the automatic RMD sweep and the dividend/cap gains in April (small amount) and December (bigger amount), it's pretty easy for us to make our spending/expenses without any real effort. He'd need to maybe make a call a few times a year to get them to walk him through the process of moving the cash over unless he remembers how or even write it down for him. But once you get the portfolio set up in low cost index funds, no one really has to do anything else other than take the money out and no stock buying and selling or fussing with the actual portfolio at all....
