Good idea to use Wayback to check some individual listings, and thanks for sharing.
FWIW, looking at the BLS numbers (Rent of Primary Residence for San Diego) and combining with Zillow’s figures for the most recent year, it looks like SD rents in aggregate have risen over 10% since the end of 2010 (4.5 years ago). That’s probably understating it a wee bit due to lag in the data, whereas your wayback comparison is looking at today’s prices… but it’s probably a decent ballpark.
So it’s definitely not the case that you could rent the same unit at the same price 5 years ago (or if you can, it’s a matter of a lucky find, and not a statement on the rental market in general).
