Keep the big opportunities available
GTA V has no built-in money cheat. Story progression and heists provide the main large cash injections; Lester’s scripted stock opportunities reward planning. A missed original assassination trade cannot simply be restored through mission replay. Keep an earlier manual save if the investment route matters to you.
Buy for a goal
Before buying a business, compare its price with the income or activity it unlocks. A property that is enjoyable is a valid purchase, but passive income is not the same as an immediate refund of its cost. Reserve cash for the properties you actually want instead of filling the map with purchases as soon as they appear.
Separate three different targets
Buying five qualifying properties contributes to the 100% checklist. Owning every property is a much more expensive optional project. Earning the largest possible balance is a third goal. Decide which one you are pursuing, then keep an expense list and check each character’s cash independently. Avoid online cash generators: a website cannot add legitimate Story Mode money to your save.
