Are you asking where the specific homes for rent are,
or are you asking where to find the rental lists?
Our MLS does have some rentals (homes and condos) for every area in San Diego County. And Trulia has plenty listed too.
For the properties on our MLS - a licensed agent can arrange to show you the properties, give you a rental application, and give you insight about the local market. An agent is of no cost to you.
Whereas on Craigslist you will need to make your own appointments to tour with each individual landlord.
I am happy to set you up with a link to view those MLS rentals online.
You can define what search range price, or size, or city etc. Just shoot me a quick email.
I hope that helps,
