I thought about this, but when I considered how much money I was able to amass as my level grew while playing Oblivion, I didn't see a huge need for it. Considering the way Oblivion merchants don't run out of money like they did in Morrowind, it's a little too easy to make cash, and I feel like owning real estate and making rent off it would only add to the excess money problem. I don't know about anyone else, but when I play a game like this I feel like I should struggle to make ends meet. Most other people in Tamriel probably aren't around rolling around in big piles of gold like our characters can, and it makes me feel out of place.
I kind of have to side with this. I mean, when npc complained about high taxes and how they only made 5 gold a year, I loled because you could make 1000x that after killing a bandit. Now, with the hope the leveling system is fixed in some way or another, that wouldn't be a problem.
As for buying houses of the dead...I just dont know. "Dragonborn realty" is a tad strange in itself to me. Why would the dragonborn be renting this house to us? Shouldn't he...be saving us or something?
What I would like to see however is more option with the proporty you can by. By a plot of land in town, choose from a few different models of homes, and then watch it being built. None of this instant mumbo jumbo poof there it is with magic stuff. I'd like to see my hous being built, and be able to talk to the workers and see how they're doing. The inside should also be very customizable. Racks that you could click on, and then place parts of armor into it, and the armor be visable. A mantle above my fireplace to hang my sword. The ablility to get some heads of dragon's I've killed. Different sizes and colors of beds. You could get a training area downstairs, a crafting area in the back. Just so my house is mine.
