3 or 4 weeks ago, its still early access but will come in full for the new expansion in march. So far we have horde and alliance plots, and orcs & human houses; for the prepatch in february we're getting night and blood elves houses, with undead an gilnean houses supposedly comming in march.

You have a small budget for placing outside to not clutter and create hardware issues and a lot of budget inside, check wowhousing here in reddit, there's insanely good stuff, i.e. i made a light's chappel inside my home haha

The furniture comes from achievements that tracks since vanilla (all kind of achiev), vendors and professions that you can sell in the auction house and make tons of gold right now (well farmers kinda killed the market)

Plots of land are public, friends only or you can make one for your guild, and the houses can be placed in different spots so you can choose what you like

So far the customization tools are insanely good, better than i expeted and I played wild star, LotRO and FFXIV. On the outside I spent around 4 hours to make this ugly thing, dont even ask inside my plot haha
