I did! manipulating objects will be wonky (no worse than in SL), and I hope they let us set some defaults that aren't there now. playing with floorplans is going to be so much fun. I look forward to seeing how you level up (more rooms!)
I keep reminding myself it's an alpha. Lots of the UI is unfinished or doesn't work. I'm eager to see the size minimums for a group neighborhood. Although I'll probably want to finish the special events, which look like they'll require a fairly active neighborhood, so public will probably be my choice unless a group of small guilds cooperates.
once you have a house in each faction neighborhood, you can go to either one and edit with toons from both factions. I haven't confirmed the vendors work cross-faction.
And in Elder Scrolls Online you can buy 3 different sizes of lots for many house styles with space around it, and also drop many many things to make it pretty.
And I guess I will wait until it's live and then see what people post what you can get where and under which conditions, and then decide what I want and do what needed.
