A cheat to find your house in minecraft?

Answer 1

There are no cheats to finding your house; you will have to make your house have a bed and set your spawn point.

Answer 2

Google 'Zan's Minimap.' It's a mod that you can install on minecraft that shows a little minimap in your top-right and you can make waypoints that it points to, I.E. your house. It works on multiplayer too.
