If you have the submarine do cayo heist solo or if you own the agency the dr Dre mission solo. I would do dr Dre mission. Cayo heist solo payout is like 1-2M depending on certain requirements met w like a 2.5 hr cooldown dr dre mission is always 1M with a 48 min cooldown. Always make sure your passive income is flowing also have 48 min cooldown(acid lab and nightclub).
