Wholesalers in Orange County, CA

[Eric G.]

I am a property manager and relatively green investor in Orange County, CA. I own three rental properties in my county. 

I'd like to continue to grow my buy and hold portfolio, but my problem is deal flow. I'm looking to buy properties in my area at 70% of ARV, fix them, and rent them.

I've read that wholesalers generally shoot to get a property under contract at about 65-70% of ARV. I know Orange County is a hot, premium market. So, here is my question:

1) Is buying at 65-70% ARV realistic in Orange County? If not, please educate me.
