They say Net Income = Operating Income - Taxes - Interest.So if someone owns multiple properties, in theory we should be able to attribute how much you owe in taxes for every property individually?

Same goes for number of LLCs and what to fund them with, since bear in mind that CA tends to be more cumbersome and expensive to have LLCs than other states.California is generally more cumbersome than other states when it comes to taxes and filings.

However your situation becomes a trickier case study since these properties first served as your primary residence which could provide additional benefits form a tax perspective not available to an owner of investment real estate and nobody has a crystal ball and knows the property with certainty will transition into an investment property. 

If your intent it primarily to resell (the definition of a fix n flip) then you can't 1031 it.But that being said, there are a bunch of my clients over the years who have shifted their model slightly so they can get the adrenaline rush of fixing and the tax deferral of 1031.
