Try zilpy.com and rentometer.com. There’s a certain skew to their data, though. Sometimes their data is off by +/- 10%. Still, they do list where they get the data from, and maybe your condo will show up there.
From the SDCAA report a few months ago (January), a 2 bedroom in Rancho Penasquitos’ average rent was $1509, at around $1.29 per sq. ft. This was probably an apartment, though, not a condo.
The UT reports today that rents have gone up in San Diego county around 3.7%. The rental market is pretty tight nowadays. I don’t see rents going down anytime soon.
