Step one make sure you have at least 5,000 gold to start with

Step two go to the Cemetery Road there are two house's on that street

Step three buy the house named "The House of Might" (break both doors)

Step four go to decoration mode and go up stairs where the two plaques are

Step five put you two most precious trophies on the plaques

Step six jump off the balcony

Step seven go to the deed and sell the place

Step eight go back up stairs and pull the trophies

Step nine jump off the balcony

Step ten repeat steps 3-9 until you get the amount of gold you want

I recommend that you use any 4 star trophy and the crystal you get by defeating the Old Kingdom Crystal Giant with Reaver, Hammer, and Garth after that you get at least 15,000 gold for each time you do it. This helped me get 3,000,000 gold with in a day if you can do this right and do it fast also i have every building in the world other than knothole island paying rent and shop prices way up this is a cheat with out a code tatty bye hope you become rich (:
