Error or Realtor trick?

It could be the case that there's a little trick that goes like this:

(1) If the house is in Van Nuys, list it in Sherman Oaks. Sherman Oaks is fancier and more people will look at a listing that would be ridiculously expensive for Van Nuys but is actually kind of cheap in Sherman Oaks.

(2) Put down the wrong zip code. That way no Zillow information will be available. ALSO! If you put in a super fancy zip code (like maybe Sunset Plaza) the sales comps will be way higher per square foot. BONUS!

Or it could be the case that the Realtor just made some typographical administrative errors. I report. You decide. Here's the listing:

13465 MARGATE, Sherman Oaks, CA 90069 ($649k)
Beds: 3
Sq. Ft.: 1,304
Lot Size: 7,810 Sq. Ft.
MLS #: F1777810

Real address: 13465 Margate, Van Nuys, 91401.
Last sale: 06/21/2006: $700,000

UPDATE: The listing has the right zip code now (but still says Sherman Oaks). And it has a new MLS # :08_301921. Just a coincidence?
