Jeremy Congratulations - I grew up in that area and cost of housing has skyrocketed while incomes have not, so there definitely is a need for affordable housing in that area (as well as pretty much everywhere else)

Definitely enter with caution.

Definitely, either the house price is far beyond its current market value, or there are some property disputes.

Those non-cash expenses definitely helped us out during tax season.2.

The biggest differences between residential and commercial:  Scalability, financing are very different, property taxes may be different, Insurance is definitely different. 

That will definitely increase blue collar wages in certain industries and decrease rental demand in certain submarkets over the course of years.

You are definitely right about that.

But if you are okay with negative cash flow and want more the appreciation, new builds are definitely the way to go. 

Finding deals off market is definitely something you can do without a "mentor".

probably, but I have no idea, I would definitely wager it's a big majority.
