However, I could not find any listings on multi-unit residential properties on the platform.  

Hey John,I work with several different property managers, which I refer to for my clients (I'm an investor friendly agent over here).

It depends on your financial strength, the quality of the property, how many properties you own, etc.I like to start with one significant expense and three months of vacancy.

As a long-time GC, I wouldn't care how you paid me.

Socal is tough to find investment properties that work.I have a great realtor in Sacramento that can find properties that cash flow.

What specific websites will they advertise your vacant property on?

Have you ever owned property?

Just want to mention that sometimes it works out better to raze an existing property down to like 2 studs and rebuild around it so that it still is classified as a remodel versus a complete new build. 

This is your property and your investment, not theirs.

Where did you find your property?
