Residential real estate is hot, and we saw that when Ellie Mae (NYSE:ELLI) -- a fast-growing provider of mortgage industry solutions -- posted blowout quarterly results on Tuesday night.

However, websites specializing in real estate are growing even faster. Trulia (UNKNOWN:TRLA.DL) posted monster growth on Tuesday night. Revenue soared 97% as the average of monthly visitors rose 52% to 31.4 million. Trulia did post a wider loss than Wall Street was expecting, but the top-line growth is what Zillow (NASDAQ:ZG) and parent Move (UNKNOWN:MOVE.DL) investors are applauding. 

Move reports on Thursday night. Zillow posts its quarterly results next week. 

In this video, longtime Fool contributor Rick Munarriz discusses why Trulia's strong top-line growth showing and its robust guidance for the current quarter bode well for Move and Zillow.
