Can anyone give advice or sources to consider what to do next logically?

@Nicholas L. it does sound like alot but our logic is this simple buy properties with as many tenants as possible so if you lose one or 2 its not a major loss to the over all cash flow. and the house flipping is just for lumps of cash and something to be active in while the multi tenant units properties are cashflowing.

The billing should be logical with a mathematical formula. 

My market (San Diego) has appreciated ~10% YOY (source Core Logic).  

Core logic states SFH are up 4% YOY.  

I just went back to find this article from First American Core Logic regarding the infamous Shadow.

i am trying to learn from all of your here, and model my actions after your trial and errors.allcash, i appreciate the logic involved in your approach, but i feel that the time it would take me to even pay off my smallest loan would be at least 3 years.

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.PM us if you’d like to discuss this logical approach in greater detail!

We are not members of the 'Tea Party' so it's difficult to understand their logic,

Unfortunately they drive the prices up to a point where sound, logical cashflow investors like yourself have no shot.
