People who claim they're getting screwed on rent usually don't know what they're talking about. People who claim they're getting a "great deal" usually don't know what they're talking about, and are jerks. Get the hard data, from Zilpy.
Presumably shorthand for "Godzilla's Urine", the just-launched Zilpy provides a visual comparison of the rental climates in cities throughout the country -- so you can weigh potential savings against your future children bursting from the womb sporting a radioactive sheen. To start, plug in a city and/or ZIP, followed by your preferred number of rooms, sq. footage, price range, and property type -- apt./condo, townhouse/duplex, or single-family home (not available in UT). Zilpy'll then display a "heat map" representing average rents, as well as average square footage, price per sq ft, and charts tracking price history for each size of apartment -- when one bedrooms climb and four bedrooms fall, you'll know Elvis has finally destroyed the traditional American family structure with his boogie-woogie devil music.
For people more concerned with caliber-of-neighbors than vicious price gougings, Zilpy also provides census-derived demographic data, including education levels and age breakdowns -- because no matter where you live, the best way to get a steal is to wait for an old person to kick it.
