Can i sell my Kosatka in GTA 5?

“No, you can’nt sell your kosatka in GTA 5, in Future if system update so it possible ”

It is not possible to sell the Kosatka submarine in Grand Theft Auto V (GTA 5) or its online counterpart, Grand Theft Auto Online (GTA Online). The Kosatka is primarily a vehicle used for various missions and activities in the game. It serves as a mobile command center for the player and is an integral part of the Cayo Perico Heist, allowing you to access the heist planning room and launch the heist.

GTA Online allows players to buy and sell various vehicles and properties, but the Kosatka is not one of them. Most properties and vehicles in the game can be sold, but the Kosatka is not included in this category. Rockstar Games, the developer of GTA 5 and GTA Online, occasionally updates the game with new content and features, so it’s possible that future updates may change the functionality of the Kosatka. However, I cannot provide information on any developments that may have occurred after January 2022.

If you’re looking to make money in GTA Online, there are other ways to do so, such as participating in heists, completing missions, engaging in businesses, and investing in properties. Keep an eye on the official Rockstar Games website and in-game announcements for updates and changes to game features, including the ability to sell or trade previously non-saleable items like the Kosatka.

So,

Yes, it is possible and  allows players to buy and sell various vehicles and properties in Grand Theft Auto V But not sell Kosatka. However, it cannot be sold. Regretfully, Rockstar does not offer a service that allows players to sell their homes and receive a refund. Trade-ins are basically the closest thing to selling your home.
