There are many lenders that say they are CalPERS Certified but have never closed a CalPERS loan. I would recommend using a direct CalPERS Lender and specifically someone who specializes in PERS loans. Preet Kalirai has been in the business for over 15 years and has helped thousands purchase and refinance. You can reach her at 1.888.415.2000 or callpreet.com . She is not in Orange county but can assist you from Sacramento if you are ok with that. I do know a good direct lender there as well if you want to meet in person. Just let me know.
...and he is a very nice guy.
