Advice if monthly income increases by $8k and 1-time cash of $1m

[Sean Silva]

I am a relatively inexperienced real estate investor - 1 previous house hack where the proceeds from a sale were reinvested in a self-created QOF that owns 1 SFH outright. What would be a good strategy if an investor changed jobs / had a 1-time cash event that: (a) resulted in an $8,000 increase to monthly income (without a change in living style) and/or (b) received $1m without having any debt to repay, so the money was entirely free for investing?
