On the home page is a link at the very bottom for Real Estate Listings. Every property currently available is listed there along with a detail page that has what is included with the house and how much it costs.
Go to the Beauracratic (sp??) Hall on Gregarious Grange in Groddle Meadow and talk to the beauracrats there. You have to get 2 sets of papers (so you'll have to leave and come back) and then you can buy homes.
beta.glitch.com/realty has the houses :)
First you need to go to the Bureaucratic Hall to get your card carrying qualification and activate it. Then you need to learn Better Learning 1 and Bureaucratic Arts 1 (you can't do this until you are at least a level 3). Then go back to the B. Hall and get your papers and activate them...Now, you are qualified to get a house or ride the subways...
While doing this...earn currants - by selling things to vendors or on auction. Mining gets you the most currants quickly. Cooking also works, but can take a little longer. There are various other means to make currants - gathering items, and selling them raw (usually auctions are best for this since vendors won't give you much for basic items).
To find houses, look for the real estate listings on your personal home page (at the very bottom). You can buy a house either by visiting a location or browsing through pages and buy them there.
Also, if you ever move, you need to pack up all your stuff before selling your house, else it stays there for the next buyer. (Some people have moving parties, others sell excess and have lots of bags). You will get 80% of your original investment back, so it can be fun to move around to different places.
