One of my faves for the Canadian market is Julie Broad's "More than Cashflow" - Canada specific and very relatable.  

That's exciting that you've started with some basic goals -- Eric is right, you've got your broad idea, now hone in more on specifics. 

I would steer clear of hard and fast rules like the 70% rule in general, they are too broad and don't work in a lot of markets in Southern California for example there is no way you are getting a house at 70% ARV -expenses unless it is off market and you are comfortable taking advantage of someone, or maybe raw land. 

You initial post is too broad.

It doesn't make a difference in the broad scheme of things. 

I wish I kept better analytics of the portfolio but it feels like it didn't get shocked as much as the broad-based indicies during '08. 

The absence of a utility bill increasingly overcomes the aesthetic arguments of roof vents and satellite dishes being impacted by a solar array.

The Franchise Tax Board takes a very broad opinion of what constitutes "doing business" in California and it's likely that if you are living in California and managing the entity, even if it is organized in a different state, you may still be subject to CA tax laws and likely have to pay the $800 minimum tax. 

The Fed acts as the regulator and sets the broad policy goals with low inflation and full employment as the guiding principles.

This is broad advice though...my suggestion again is to speak with your agent about the specifics of the deal so they can guide you.
