I have two rentals and one is owned free and clear with a value of $80,000.I also have been a landlord for over three years now.I would like to leverage my $80,000 property to buy more properties and increase my positive cash flow.

You get better leverage and have less cash out of pocket.  

Once in awhile I get requests from programmers trying to develop an app or some program for human intelligence, can't be done, while parts of the analysis can be accomplished much easier with technology we don't have artificial intelligence to make objective and subjective determinations.

This is making me start to feel old not understanding the technology!

With the information discovered, you may be able to use that as leverage.

I wouldnt be surprised to see them acquired by appfolio for cheap after this, and after that gain another key vendor leveraging appfolio value added relationships.

You definitely have a great opportunity to leverage the equity in those properties to acquire even more, so as long as you buy more positively cash-flowing properties then you should be good.

HOA investment programs give the investor tremendous leveraging power in purchasing distressed homes. 

This is called the Velocity of Money, and leverage (debt) can be a very good tool to increase that velocity.
