Property investment is a smart move. You can buy properties in the game like garages or businesses. As you upgrade and manage these properties, they can generate a passive income for you. For example, a nightclub can earn you money over time if you keep it stocked with supplies and promote it well. It might take some initial investment but the returns can be good in the long run.
Robbery missions are a great source of income. For instance, the jewelry store heist can earn you a lot if you plan it well. You need to choose the right crew members, the approach, and the getaway vehicle. Additionally, you can look for hidden collectibles like the spaceship parts or the letter scraps. Some collectors will pay you good money for these items once you've collected them all.
Do heist missions. They usually give a large sum of money at once. The Pacific Standard heist is one of the most profitable ones if you can complete it successfully.
Doing side missions for different characters is good too. These missions give you cash rewards. Some side missions can be repeated, so you can keep making money from them.
One of the best ways is to complete heists. Heists can bring in a large sum of money if you plan and execute them well. Another way is to invest in the stock market within the game. You can look for trends and buy low, sell high. Also, doing missions for various characters can earn you a decent amount.
Participate in races. There are various types of races in GTA V. If you're a skilled racer, you can win races and earn prize money. Some races also give you additional rewards like new cars or upgrades. You can practice your driving skills in free roam and then enter the races to make money.
Do the main story missions as they often reward you with a decent amount of money.
Hunting is really good. Big game animals give high - value pelts. For example, a perfect grizzly bear pelt can sell for a lot. Skin the animals properly to get the best price. You can then take the pelts to the trapper. He'll give you more money than just selling at a regular store.
Go to a Pay 'n' Spray. It's a great way to quickly lose your wanted level as it resprays your car and makes you less recognizable to the cops.
Hunting is a good option. Different animals have different value for their pelts. Big game like elk and moose can give you more money when you sell their pelts. You can also hunt small animals like rabbits and squirrels, but you'll need to hunt a lot of them to make a significant amount of money as their individual pelt value is lower.
One effective way is to end with a resolution. Tie up all the loose ends and give the characters a final state that satisfies the reader. For example, in a mystery story, the detective finally reveals who the culprit is and how they did it. Another way is to end with a cliffhanger, which leaves the reader wanting more. This can be used if you plan to write a sequel. Also, an emotional ending can be very effective. If it's a love story, perhaps the couple finally gets together after many obstacles, leaving the reader with a warm feeling.
