Alright so I have 2 cheats. LP & Simoleans. You need facebook for both cheats.
Okay, so first get and empty house.
Then fill it up with the neighbor items.
Get the highest one you have and it has to be an inside item.
As you can see it makes your town value go up.
That's how you get LP.
Continue..
Then once you filled as much items log out of Facebook on the game.
Then go back and sell the neighbor items.
Items are worth more now(:
Welcome hope this helped!
