If you're the kind of person that needs hard math and graphing to understand things, this is completely the book you need on building wealth through duplex living.If your wife is behind you in this idea, and can see it as a move to financial independence, congratulations, you're in the small minority, as I am.

It is code here where I live to have moisture barrier as part of the build.

Building a real estate business that way is a house of cards (pun intended). 

If your investment strategy is to AirBnb, you had better build into your approach legal risk, because if you buy assuming that you'll AirBnb, then the city passes ordinances to force you to long-term lease (VRBO... monthly, 6 month, or 12 month), you'll be screwed if you cant cash flow.So, AirBnb investors generally don't have staying power. 

I feel like I should be looking for bigger investments yet I’m comfortably investing in small multi family and single family homes here with high equity build potential but very low,if any, Cashflow. 

My strategy has been buying a primary every year, and since 2017, it's helped me build a pretty great portfolio with the minimum down every year.

I spent the summer furnishing the house, to include building bunk beds in my garage.

I'm under contract to purchase an apartment building in Ohio.
