this is not a cheat. But what i do is i have all my sims that arent working plant stuff while im sleeping. wake up in the morning, and voila! You've got money! I also do that while Im at school. Also, you can plant corn? (i think its corn. i forgot what food it is) for 20 min and it pays 100. you can also plant watermelon for 1 hour, 160 simoleons. See how that doesnt add up? In one hour for corn, you can get 300 simoleons, which is the amount you get for 2 hour potatoes. Yes, there are 30 second bell peppers that gain 4 simoleons, but those are a pain. You can also do 5 minute carrots that get you 28 simoleons, but I dont like coming back every 5 minutes. But when you're asleep, might as well set the 7 hour (or how much sleep you get), because you can't plant carrots or corn when you're sleeping. I know its not a cheat, but it helps. And warning: The time cheat can mess up your game a little. It makes my actions take longer, buildings being built after the time that was given, and a late party boat. It completely ruined my friend's game, and she restarted. We tried to do what it said online to fix it, (setting back the time, switching off device, etc.) but we never retrieved it.
so so sad :( anyway, be careful with those cheats. Also, the luxury car costs 60 LP. The beach house costs 50 LP and comes with the same car. Just buy the beach house (only available premium land). You can get LP when you tap the notes when you have your sim go on a drive. You have to go to Town Map while they are driving to do this.
