How to use these numbers
These are Zillow Observed Rent Index values, a smoothed measure of typical asking rent for single family homes, condos, and apartments in each ZIP code. They describe what units are listed for, not what any specific unit will get. Condition, bedroom count, and the exact block all move the number.
If you are underwriting a purchase, use the ZIP figure rather than the city median, and then verify against live listings for the same bedroom count before you commit. El Cajon sits in the San Diego-Chula Vista-Carlsbad, CA metro area.
