Based on that $4M purchase price, you should be able to purchase around 16 homes in Bakersfield producing an average rent of $1700/month/property. 

It give you the benefit of having multiple units that produce income.

Folks outside of California seem to think that appreciation is only possible on properties that have negative cashflow, or that properties in California only produce negative cashflow.

that will be valuable in building your network--with a specific intention of building a buyers list for the leads and deals your marketing will produce. 

I have bought properties for under $30k as late as June of this year, Single Family Residence (SFR), and fixed it up for another $15k ($45k total) and it is producing over a $1,000 in rent now per month.

Rentals will actually produce double rent and everything will be fine" ¯\_(ツ)_/¯

I was curious, from an appraisal standpoint, what people have seen when adding additional income producing units to single family homes. 

I'd suggest a blended approach maybe to further shore up your security.First take a look at those properties and identify the one (not your residences) that either have higher debt or are under producing what you think you could get with a different structure. 

In other words they give you a $100 credit towards your job if you paid them that much to produce the bid. 

My goal is to have cash producing single family and multi-family homes and to have passive income exceed my expenses ala "Rich Dad, Poor Dad".
