I own 3 houses, all fully furnished: 1 in chorral (main house), one in imperial waterfront, and one in skingrad. I've done about 80% of the daedric quests. A ton of freeform quests, including the lengthy pale pass quest. A ton of sidequests- about 20ish or so (I can get specifics later). I'm up to the third part of the nirnroot quest (have to get 30 now =() too. Not to mention, I've read most of the books in the game too. Haha.
My character is level 36. My seven major skills are: blade (95ish), block (78ish, I tend to move around more than stand and block because my agility is low so I get recoiled a lot), heavy armor (95ish), alteration (100, unlock all spell 4tw), illusion (100, chameleon 100% 4tw), mysticism (65ish), restoration (60ish).
Overall, my goal wasn't to rush and get them all. I just did them at my own pace. I think the order I did the guilds helped too. Since I did mages first, I got my magic up very quickly. Due to my super high alteration and illusion, I was able to do the thieves and dark brotherhood quest lines very quickly (probably less than half the time a weaker character would've taken).
In any case, I got a few things left to do with my main character then I'm going to make a evil vampire character. ^_^
