Forms for selling house/property in California?

[Mark Hu]

I am thinking of selling a rental house in Southern California by myself. An escrow recommended I use CAR (california association of realtors) forms, and I would agree they would be the safest. However they are godawful expensive, $200 for a pack of twenty residential purchase agreement forms, and so many different types of forms might be needed, such as counteroffer forms, contingency release forms, ect. Now I know one is not legally required to use CAR forms. Has anyone here sold a house or property using their own forms or forms from a different source?
