We don't really have cash flow machines for rentals, but that could happen.

In the mean time maybe I can make some "virtual" contacts.

Callfire.com or voiceshot.com for call blasts; automatically calls and plays recorded messages Use Jing/camtasia/screenr to record videos of your computer screen (for creating training videos for your virtual assitants) Use Odesk/elance/Virtualstafffinder.com to find virtual help Use Vflyers to advertise your properties; it links back to your personal website...make sure to have youtube videos of the property as well.

I think something that is missed when we analyse our history to make forward predictions is understanding out monetary system and with that our global economy and what our trade balance means for our economy.http://pragcap.com/how-the-economic-machine-works-by-ray-dalio

And there are many whose size, layout, and/or ceiling height make them virtually unrentable.....9x7 masted bedroom with 7' ceilings, no thanks.The more info you can share, the more we can help. 

My first thought is large vending machines like those from "Twice the Ice" and lease square footage to that person who wishes have one there.

Is it then a good idea to start in virtual wholesaling?

Just finished The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Technologies .

Don't "lock down" your software on a specific machine or platform; run it on the web, and open up options to tie in to other apps and processes (online application & payments, for example).

They can work virtual no problem.
