First time Investor Pre-Approved - Now What?

[Nick Victorio]

I currently rent an apartment and have decided to invest and house hack. Ideally, I would want to get a duplex - fourplex to take advantage of the pre-approved FHA loan I have received. I live in Oceanside, CA ( north county San Diego) and prefer finding a location 1 hour away (flexible). With little experience and just browsing the MLS portals, I am curious if I am missing inventory that is listed directly on the MLS.

How do I find a realtor that is invested minded with investments themselves?  I am licensed with 8 years of property management experience.   Whatever I can do to reciprocate the good BP Karma I will do.  I am really hungry and at 39 I need to expedite this process.
