Solid blue collar trades that are too big to operate from their garage but not large or stable enough for a stand alone building purchase or lease.

You have this base of cashflow, maybe you can take a little less cashflow on a property and trade it off witha chance of speculation/apprecation.

What the article describes is akin to insider trading in the stock market.

And it had to be used in your trade or business..

So in 2004-2007 in Maricopa AZ a way off place south east of the Phoenix was experiencing HUGE price swing just based on speculation of the market.

Don't want to get into details but it requires coordinated activities with three separate trades, and bottom line is my tenant is not going to be able to use the kitchen sink and dishwasher for a period of time. 

We don't have crazy swings in appreciation like the coastal states do, but you can consistently find cashflow properties that meet the 2% rule with hard work here.

And finally, to trade in this suit I have been wearing daily for 27 years (yes approximately 7,000 days) for a pair of shorts, Investing advertisement T-shirt, and a pair of sneakers or Flip-Flops!

Unfortunately, since I work swing shift Wed, Thurs, Fri, Sat, it would be difficult for me to make it on those days.  

It only gets a bit muddy if you are trading services for rent.
