It isn't really a cheat. Depending which houses your willing to sacrifice, demolish and build mansions. This will give a luxury car(worth 60 LP; most expensive)each time. If you have teenagers, select "Learn to drive" option. This allows you to follow the luxury car for 5 hours. Cash and LP's are aware the longer you follow the vehicle. If you have eight going at once, you will receive 8x cash and LP's. If the island monument, The Riches of Terra, is upgraded, purchase/place ten garden patches in the year of one residence and grow bell peppers repeatedly: Free inatant cash. The more island monuments and higher upgrades give more cash, XP, LP and treasure. The Pirate Quest also increases hobby skill level when the Ancient Goddess is built. Hope that helps.
