Would you want to spend your loot on vanity projects?
Not really. I'm usually baffled by the "I need more gold sinks to spend my money on!" threads.
One reason is that I see having a bunch of money as a sign of success.
Another reason is that I love looting stuff, especially in Bethesda games with the whole "enemies have all their gear on them" thing (rather than the "random drop 0-2 items" that many games have.)
And another big reason is that I tend to become self-sustaining in Beth games.... I don't actually spend much money on anything - if I want/need something, I tend to try to find, loot, or make it. (Oblivion, for example... beyond a few spells that I might need for enchantment effects, the only thing I ever spend money on is repair hammers.)
But I'm also aware that I'm somewhat in the minority.

(also, house-wise, all I really look for is a wide array of boxes to store & sort loot into. The smaller, the better - less distance to run between containers. Breezehome is perfect for me in Skyrim, and in Oblivion I just installed a mod that gave a reasonably straightforward home near the IC.)
