As well as your Speech skill, from selling all the crap you enchanted, which will also make you money since prices will improve. Adding perks to Speech will improve returns even further, but most folks don't bother as it isn't really necessary.

If you loot everything you can get your hands on gold becomes a non-issue. 4 houses and 100k gold in my pocket. Would be more but the merchants never have enough gold to buy all the wooden buckets I bring back.

I do that all the time. It's a great way to get your money back and level up your Pickpocket!

You can also use the Slow Time shout...there are several YouTube videos showing this.

I won't use a cheat but I'm going to have a real challenge in buying a house with a pacifist character I'm planning. I'm wondering if it will even be possible. The goal is zero kills and so many quests want you to kill something. I'll give it a shot though and if I can't find a way, I'll get a mod.

Is that even possible? :\ ...so many NPCs you have to kill to get the quest items. Plus, I'm just assuming that at some point we'll have to kill Ulfric regardless of what side we choose. There can be only one! XD

And FWIW: the house thing is an exploit...not really a cheat. Just tell yourself: "Bethesda made it possible and I just don't want their work to be for naught." XD

Wrong! You have a house and thousands of gold Septims.
