How To Strategize RMDs on Four IRAs Inherited April 2025

We inherited four IRA accounts (totalling approx $600,000) in April 2025 due to an elderly parent's death. By law these four accounts must be completely depleted within ten years. What is the best strategy for making RMDS over the next ten years with the least tax liability to us? Our 2024 AGI was about $48,000.

Thx.
