We have emails, video conferences, secure portals etc etc.We do have a physical office, and half of our clients are local.

You aren't the insured in this case.Renters insurance does not cover the physical damage of the real property - it covers the tenants personal property and other things. 

You can visit the property, contractors, etc where as Detroit will either involve longer travel or trusting someone on the ground when you arent physically there.

So if there is any kind of physical harm to the tenant say due to slipping on the stairs etc. the tenants renter insurance will cover the medical cost.

Does physically going to downtown reveal more info than the Cook County Circuit court website?

The obligation to mediate, unless otherwise agreed, will terminate if the entire dispute is not resolved within thirty days of the date written notice requesting mediation is delivered by one party to the other at that party’s last known address (physical or electronic as provided in § 26).

As I've witnessed, rebranding can make a significant difference in the success of a property, even if the physical appearance remains the same.By charging appropriate fees, exploring additional income sources, and undertaking property rebranding efforts, real estate investors can unlock the full potential of their investments.

Not sure if that is physically or financially feasible to you.

Short-term maybe short it, for the reasons you mentioned OP but this investment is a physical long-term one so you analyze it appropriately. 

Here's how I do my due diligence:1) Portfolio matching: (takes 30 seconds per deal)a) Have an educated opinion on where I think we are in the real estate cycles (financial and physical market cycles)b) Then and only then do I pick the strategies, capital stack, and specialized asset subclasses that make sense for that opinion.
