The Elder Scrolls V: Skyrim Glitches

Free Houses (And Decorations)
To get the option to buy a house, you have to be Thane of a town. Being Thane requires you to complete certain favours for the Town's Jarl. Then, when talking to the Jarl's attendant, make sure they are situated close to a 'container' (dresser, box.,etc to store your stuff). Go through all of the necessary dialogue, and confirm your purchase. As soon as you have pressed that button to confirm the purchase, quickly tab out (TAB, B, Circle) so you are no longer in the speech menu. As fast as you can; deposit all your gold into the nearby container. You should get the item you purchased and give up that 5000 (or whatever) 'non-existent' gold you currently carry.
