This depends on your goals and current savings. Are you looking to FIRE? How much do you have saved in retirement/are you on track for your retirement goals? Any other major expenses/purchases in the horizon?

Always split your investing between timelines. Personal rule is to always bucket long term first (retirement), medium term (if applicable), then short term. After all savings goals are accounted for, the leftover money goes towards living/fun expenses.

Considering your income and timeline on a house, short term investing is probably the way to go. CDs are pretty solid rates right now. Tbills are also an option. Last option is an HYSA, which is still pretty solid.
