Hi, If you are speaking about what to charge for rent? Go to: http://www.rentometer.com/ca
and plug in the required information to see what the statistics are for rental rates charged.
As a local Real Estate Broker, I can tell you that there is a huge demand for rental properties here at this time. This is due to home-owners who have lost their homes. As a real estate investor myself, I rent out one of my properties to a great couple who had great credit until they lost their home. They were upfront with me and told me everything I would find on their credit report.
After doing a through screening, including making sure they had a stable job with enough income, I decided to rent to them and they have turned out to be model tenants. So don't be afraid to rent to someone just because they lost their home.
If after going through their application, income and credit report if everything else looks good they will probably work out fine.
