Home loan

A mortgage, also known as a debt, is a sum of money owed to another person, almost always being Tom Nook. In addition to the initial house, each home expansion has a mortgage associated with it. After the mortgage is paid off, the player can expand their house. After the player pays off the mortgage once, the price goes up. Tom Nook will eventually say he can not expand any more. In the original game, after the player completes their mortage, they will have a statue put up in front of the train station. In, after the player completes their mortgage, he/she will give the player a flag.
