Well, "house condition" is mostly right, but they don't use the word "condition" in quite the same way. In this case, 房屋情况 really refers to where the apartment is facing north/south or east/west, and how fancy the decor is. 

房屋户型 also doesn't really refer to the style so much as the layout and sometimes the size. How many beds and baths, rather than "a courtyard home" or "an apartment home".

In terms of apartments being furnished, that's a slightly more complex question than you may have anticipated - I'm not sure if this is true in all Chinese cities, but in Beijing and Shanghai, most apartments come at least partially furnished. That's expected. Every apartment I've lived in or viewed has included at the very least a bed, a couch, a desk, a washing machine and a television. It's actually finding an unfurnished apartment that's hard - I've had to negotiate with landlords to get them to move stuff I didn't want out of the house. So these listings don't usually say "furnished" or "unfurnished" - it's more a matter of which pieces of furniture and appliances are included.
