What happens to my gta online properties if i restart story mode?

In GTA Online, properties are permanently linked to your online character profile, not to the story mode progress. When you restart or reset story mode, it only affects the single-player narrative progression and does not interact with or delete your online assets. Your properties remain secure in your online garage, warehouse, and other locations because GTA Online maintains its own independent save data system. This separation ensures that players can replay story mode without losing their investment in the multiplayer component.
