Where / how should should I move around my savings to keep my timeline in check.

Brief breakdown of my salary/expenses/age:
Age: 26
Salary: 100k net pre bonus circa 120-130k net post (anticipated growth in the future)
Savings: 230k
Monthly expenses: rent 500$ (I live at home still, VHCOL country rent would be circa 3.5k should I move out same price if not more expensive than mortgage)
Gym: 125$ phone: 185$ parking spot: 125$ Apple TV/Music: $20 Bar/Food/All other: 1.5k-2k
Typically save circa: 5.5-6k a month

My timeline for purchasing a condo/home would be in the next four years, so I’m unsure what I should do in regards of savings. In theory yes I should park it in a HYSA and begin investing but I also do not want to lose my banking relationship / perks which requires I maintain 200k+ in the account. That being said I do already have the down payment for a home and in the next four years will likely save an additional 350k should no unexpected expenses arise, assuming I move out for a year or two factoring in salary increases let’s just assume this would be 250k-300k.

I’m in a cross roads of if I should a) dump 100k into VOO, rebuild my savings back to a down payment level. Once achieved then invest 60% every month, 20% into savings and 20% into expenses.

Hopefully enough context, and look forward to your thoughts and opinions.
