Would you save in taxable or savings/money market account?

Here is the situation....

44 years old
Currently maxing out 401k, Roth IRA and HSA.  That leaves me with about $1800 each month to save in some other manner.  I currently have a Taxable acct with Vanguard, 100% VTSAX that I opened end of 2018.  Currently have $26,000 in it. I also have a Capital One 360 Money Market acct with $58,000 in it.  6-months expense for me would be about $18,000 so I am well over that amount. 

For a lonnnng time I was just putting all extra money into the Cap One account not really knowing any better, until I realized I would be better off directing some of that money to taxable.

My wife and I want to buy a house, but we live in HCOL area so we really don't have any concrete plans on when that would be. Its kind of a "nice to have" right now.

My question is, if you were me how would you split that $1800 a month?  All go to taxable/VTSAX?  Or keep putting some of it in Capital One acct?   I am torn on what to do, as I know my house buying plan is not set in stone at all at this point.

All to whatever asset allocation I had decided was appropriate.  If 100% stock is your strategy, VTSAX is a reasonable tactic.

What are the chances you will buy the house within 5 years?

How much will you need for a down payment?

I think you need to firm up your goals for the savings and that will make the asset allocation clear.
