i just got it how do i go inside a house?

If it's functional and you are of level to enter, right click. Not all doors can be opened or entered.

If the door is closed, you must /say the secret password for that house to get the door to open.

Also, don't forget to run laps around the auction house as this will build up stamina.

If the door is open, walk right in. if it is closed, you will most likely never need to go in at all.

Good luck, have fun, don't beg people for things, they hate it!

You walk through the doorway. Some doors require being opened, they will turn your cursor into a gear if you hover it over them. To do this, right click them. Other doors can not be opened at all.

In WOW, not all buildings are functional. Some are just for show. If there is a closed door or gate to a building that is not clickable then it is for show only. There are some cases where it may be an enterable building but an alternative entrance. Were you looking for something in particular? What house are you trying to get into?
