So if you had 20 of them, you're talking about a huge retirement kicker that you can build.If you're up there higher in age (i.e. 40's or 50's), then the long play doesn't make as much sense. 

And dont know about Ken.. but his partner for sure was very versed in sub to.. the information was accurate as we both kind of played in the northwest sandbox . and before sub to foreclosure rescues / rent backs became illegal in about 08 I personally did a few hundred of them. 

In playing with the numbers a bit, I'm seeing a trend of atleast 2% rent to price and (ideally) < 7% mortgage rate needed to achieve a decent cash on cash rate.

You will not have the rate long enough for it to interfere with your current and proposed profits.This is where having a good team comes into play for example having a seasoned realtor who knows the market on the purchase/ARV side.

We want to buy an arcade machine for our STR that plays a bunch of different games.

This platform has played such a key role in my journey over the years.

So it can be good for cash flow and building in tighter spaces but it is less of a equity play in today's market if you're looking to sell right away

Columbus is going to be more of an appreciation play and cash flow margins will be tighter in the beginning. 

Sounds more like trying to win a popularity contest, aiming to gain votes and likes from people here that also have something against wholesaling.But OK let me play along.Let's fact-check this:OP: "It’ll truly be strange to even hear people and gurus trying to make big money off it."

This will be a 10 year play.
