Where to invest down payment (5 years or less)?

I have >$250k invested in fixed income since June 2024 because I had no immediate plans for the money and thought I might in 6-12 months. Some are starting to mature and, as of now, I don’t have buying a home on my radar for 2026. But that could change. Should I keep investing in fixed income (bonds, T-bills) as the existing ones mature? For context, I have 401(k), Roth IRA; traditional IRA, HYSA (incl. CDs). I live and would buy in Los Angeles. EDIT: I’m considering ETFs (e.g., VTI/VXUS). Nothing crazy.
