As far as the Marshall Reddick question goes: I think he's retired (and now run by his former colleagues) and it is just a local company whose free meetup I went to; they procure these free listings on their website and do some analysis for you so it is easier to do the math, at least, in a preliminary fashion.  

Invest all those $10 savings and there's your retirement...

I'm looking to house hack so assuming everything panned out, I would move into one of the "units" that we created and once the rehab is complete, rent out the other units (In total have a 2/1 + 2/1 +1/1).FundingCash savings set aside for Real Estate ($8,800) + What I could loan myself from my retirement account ($12,428) = Total personal investment of $21,228.My first thought was that I would have to use an FHA loan due to low down payment, and probably a standard 203(k) to help cover the rehab costs.

It will come in handy when I decide where I will retire at. 

Dad's retirement plan goes with it.  

Money Mustache is a great blog to read, especially this post: The Shockingly Simple Math Behind Early Retirement.

Joseph, what started as a hobby for me 10 years ago allowed me to retire early and cash flow life. 

Can you recommend any podcast episodes (on the BP podcast or any podcast) about buying, selling, renting or managing retirement homes?

If you buy something that cash flows and make money for all those years, and use that cash to buy more properties, I'm pretty certain you would be way ahead vs waiting for the appreciation (although I can't officially say that since I haven't a full IRR, but I can say I didn't retire in 7 years by waiting for appreciation.

The ultimate goal is to own a small portfolio of around 10 homes (current goal of 1 a year) that will produce good cash flow and leave me with a nice retirement plan.
