House guide

   This is the first house you get when you first start the game. To upgrade any of your houses you must pay Tom Nook your money (dept). 

  This is the second house you get after upgrading.     The first floor gets a little bigger.

  This is the third house you get after upgrading. Your first floor is as big as it can be.

  This is the fourth house you get after upgrading. Your house gets an attic. Sadly, the attic can not get any bigger than is is.

  This is the final house you can get. You get a basement but once again, the basement cant get any bigger than it is. After you pay for you basement, you can get a flag from Nook for free.
