I do something similar, albeit a bit leakier. I have all my money coming in to one nexus account, and then I have weekly&#x2F;biweekly&#x2F;monthly outflows of everything (bills, stock investments, transfers to 3x different banks, mortgage). I keep that account with a bunch of buffer, but ignore all my other accounts. Each month I keep that main account &#x27;floating&#x27; is another month where all those other accounts are growing. If I ever dip too low, I can supplement with one of my other accounts.<p>It&#x27;s not a great solution, but it&#x27;s the one that I&#x27;ve stuck with best.
