Good Morning Daniel,I am the owner of National Property Inspections here in Knoxville, TN and my team and I would love to be a resource for you.

I know @Brad Clarizio mostly works with investors, he may be a great resource for you!

There are two possibilities going on here and you didn't specify which one you're dealing with. 1: they work with a company that installs the panels, gives them free solar energy, and then sells the excess.

An alternative is either changing your acquisitions strategy (self sourcing deals if you have the time/money/energy), or pursuing a different type of asset if you want.

If you want to look up the original article, which has links to sources and to other great resources, (I can't link as per BP rules) the article is called "33 Real Estate Statistics That'll Change Your 2019 Strategy" - by Mike BlankenshipGeneral Real Estate Statistics In 2018, 5.5 million existing homes were sold in the U.S. 

The key here is resourcefulness.

I've followed discussions on biggerpockets and it's been a good resource.

You must be more resourceful than this. 

The Trulia crime map is a good resource
