No, once you've bought a house you have it forever. Dont worry though, after a few levels money wont be much of a problem :)
Probably because it's a pretty basic home. Personally I like Hjerim in Windhelm the most because it's got the most display cabinets and manniquins. And there was a serial killer living there ;)
Yeah, Hjerim has that great armory. I like it too.
My favorite's the Markarth one, though. Vlindrel Hall. Add some 4k texture mods, and it's just sexy.
i loved hjerim too for the bloody mess but now im all about that raven rock house.. just wish i didnt have to get on a dang boat to get to that map... too much darn save screen-ness
Umm.. fast traveling? Lol sorry, just checking because I´ve seen some players who just didn´t know that you can also fast travel there. And every time I saw them going to Windhelm, taking the boat, blah blah.. and asking "Dude why you do that, just fast travel?" And they were like >_> :D
