No matter how many times you use an object, if you sell it the same day you got it you can get all your money back. In three game weeks you should have a very high speed writing, 9 or 10 novels as best sellers, and 100,000 Simoleons. With the 'Writing' skill maxed out, you can make approximately 40,000 Simoleons every week, which is more than the 34,800 Simoleons you can get by purchasing all neighborhood businesses, and takes less time to achieve. You will get royalties for six weeks once you finish a book. The most money can be made from 'Romance Novels'. If your skill is high enough, you will be able to write more novel types/genres.
When you write, your skill will automatically advance. They will not bring you too much Simoleons. Write fiction novels as they take the least amount of time. However, you will be given the option to save your neighborhood before enabling cheats so you can resume the game later without cheats enabled. Note: Using cheats will disable challenges and trophies. Place him on your lot, and all cheats will become available.
Once your family is in a house or location, pause the game, hold L1 + L2 + R1 + R2, and it will say that Spoot is now available under 'Decor Miscellaneous'.
