Does anyone have access to the LandVision software that would be willing to share access?

With this type of loan I would find a good mortgage broker who has access to multiple loan types and just ask them if there is a clause or what they know about it.

Any free/easy access first attempts for Lake County?

If nothing else works consider changing the locks, installing a lockbox with a key and leave a note explaining they have to call you for access.

I have a commercial unit ($350) that makes quite a bit of improvement.If nothing works, you may have to replace the flooring or paint it with an oil-based Kilz and then put down something else for flooring.

The only 2 ways around will be to owner occupy with the homestead exemption, or own property that is zoned commercial.

I plan to continue to buy rental or commercial property. 

Likewise I worked in commercial construction for a few years and really enjoyed it. 

In one county, the information was easily accessible online, but in the county next door, you would have to go to the county clerk recorder and request the information.

Your friend will have to look at commercial options if he holds title in an LLC.
