2Lynn, in California, very few listings are put on the MLS for rentals. Most of them are pocket listings.
I commend you Juan for reaching out to the public here, Craigslist and Trulia has some fake rentals listed so it is difficult for renters to find a home. Also, because someone may have a listing for sale, but haven't thought about renting it, yet.
Juan, give this a try... search the MLS for homes which are not short sale and not REO which are vacant and approach the listing agent regarding the possibility of a rental.
