It looks like you’re mixing annual cost and month cost.

My preference is a mix of free and clear properties and leveraged properties.

Absolutely, but you have your terminology a bit mixed up, but any agent can help you get to the bottom of that.

Chicago is very segregated, is a mix of everything you can possibly imagine. 

I'm looking at a 6900 sf mixed use property that needs a lot of work.

I have a mix of completely paid off properties with no loans, paid off properties with HELOCs on them (presently unused for quick easy access to capital), and properties with low interest mortgages (leverage) on them.

There's a new tech company that uses 3D printing to 3D print a tiny home for just $10K.

I tried educating myself on different aspects of a mixed use business/apartment investment property but the terms and phrases I used kept yielding irrelevant results.

Other thought is that while I am not too familiar with Ohio laws or process, if your property is zoned industrial but it's in a more mixed use area then if you can't get in a tenant, you can usually get a variance for some other, more commercial use.

Mix it up otherwise people will start identifying your design with spam.Hope that helps.Sharad
