My wife and I combined generate low 6 figure income from our jobs, we have no car payments, and the mortgage on our house in quite modest.

You would do this to generate cash.  

However, I just learned from my power company that the energy bills of the previous tenants went as high as $570 during the very cold winter months ($200/month average).

Do people find them to be better lead generators?

I am spending my time and energy operating three separate businesses - one seasonal service business, one retail, and one e-commerce website.

Obviously this isn't a scenario where you are working a farm and trying to generate any potential lead, but a smaller, more hand selected approach.

How much rent do you think it can generate?

I'm the third generation following the same path trying to grow the empire in the continental USA. 

@John JacksonI guess I’m still unsure how to decide between buying cash and having that much more cash flow as oppose to putting next to nothing down while generating less cash flow, but having some cash left for another deal thus creating more cash flow.  

It's getting the next generation comfortable with selling their home online and Auction.com is at the forefront of this.
