VGD Money Mkts - Checkwriting

[Second Round]

In the old days I had a couple of VGD money market funds - Prime MM and Treasury MM. Today, I have VMRXX and VUSXX, i.e., Cash Reserves Federal Money Market Fund Admiral Shares and Treasury Money Market.

We're in the process of transitioning off the mutual fund platform to brokerage (after much nagging by VGD). While doing so, I noticed VMRXX does not offer checkwriting. Given that we may someday wish to get a big chunk of cash out of these accounts (say for a different house), what reasons are there to keep VMRXX and not just consolidate these money market accounts into VUSXX?

Although we rarely use checkwriting, it seems that moving house-sized amounts of cash around can be subject to limits that might make assembling cash for closing a tricky process (assume cash purchase, no or only small / short term mortgage). FWIW we are mid-50s in age, in the 24% federal marginal tax bracket, and have no state income tax.

The ER and yields between the two seem to only differ by 1-3 bp. That seems inconsequential to me, frankly, but I'm more focused on the big picture (and simplifying when I can) than optimizing to the basis point.

Thanks in advance!

By default, Vanguard brokerage accounts use the settlement fund for checkwriting. Once you account is established you can designate an alternative fund that you currently own (limited to money market funds and most bond funds I believe) for checkwriting. Once you designate an alternative fund for checkwriting, you do not need to keep any money in the settlement fund for checkwriting. Follow these steps to get to the correct section to set it up: MY ACCOUNTS -> ACCOUNT INFO -> PROFILE AND ACCOUNT SETTINGS -> BANKING AND MONEY MOVEMENT -> CHECKWRITING.

Brokerage check writing will always pull money from the Settlement Fund first. When setting up check writing (or after setup), you can designate an alternative fund from which check writing will pull the money (if insufficient money in the Settlement Fund).

OK, good to know. Thanks for that link - I had many of the same questions as the OP there. I grew up with mutual funds and am not a trader. So my intuition is to not have much in a settlement fund, even if it is said to earn the same as a regular investment in VMFXX. In that other thread, it's implied that it doesn't make much of a difference. I would not be surprised if having more in a settlement fund induces, on average, more trading behavior though.

Thanks!
