James, Thanks for the book suggestions, I will order them right away and develop a more thorough knowledge on this - very appreciated!

I found this one really good article on sub-dividing, and then using Oakland's mini-lot development guidelines as an approach to this: http://www.jgutierrezlaw.com/uploads/Subdivisions....Is there anyone around that has subdivided their own property in Oakland?

I do agree with @Anthony R. that you need to be sure to include enough in your budget for repairs and also Capital Expenditures (new roof, furnace, etc) I think @Ben Leybovich did a study a while back and found the average home in American needed about $250 in repairs per month if you really figure in everything that will eventually wear out (the entire home accept the foundation and framing).

I will initially be looking to purchase 2-4 door multi family property, however my goal is to eventually move into the 10-50 door apartment complex space. 

Turnkey is a long-term investment focused on cash flow, so you let your tenants pay off your loan, you pocket the net income for a while, and then eventually the property is paid off and your cash flow balloons, usually around the time you really need it for retirement.

Due to the low new development over the last 7 years and the influx of people relocating into the SGF market, inventory is incredibly low across the board. 

I will give you both sides:as an agent and developer.

A ton of development and renovations happening in the area and you still have the commuter rail which is making it an ideal place for young buyers. 

That will keep you out of trouble and help you develop a strong reputation.

Many investors are currently focusing on value add and cash flow over development deals due to their perception of where we are in the market cycle.
