How do you buy houses on the game Oblivion

First, go to the count of the city you want to buy a house in, then make him like you (if needed) and talk to him about Buying a House. He should talk to you about it, and if you have the required amount of gold, you can buy the house. You can also furnish it at the local shop in town. This obviously costs gold. The cheapest house is the Imperial City Shack, while the most expensive is the Skingrad Mansion: Rosethorn Hall. (This costs at least fifty thousand Septims, while the Shack costs at least three thousand, this is with the furnishings added.) There is one house within each city, each at a different price.
