Any profit split varies depending if your relative just gives you money or also helps you physically. 

Here is what worries me- 220K- that's just the physical labor.

I would physically visit the property that you may be interested in.

You can easily set up an LLC in Ohio online through the Secretary of State for $99, however your Resident Agent must be located in the state of Ohio, which means they have to have a valid physical address in the state.  

I don’t know that there is a defined policy stating how frequently you have to physically occupy the property or how many nights you ha e to sleep there - maybe you like to go camping a lot, or maybe you travel for work, but you do have to call the place home for a while...

Another way to own a non-Turnkey property , is to consider a Partner that lives in the subject area and is willing to help you physically. 

Most of the time, people just mail to physical addresses.

How do I get the physical address from this? 

You'll never get the money but at least you get rid of him.This is why it's important to inspect every unit before purchase (including physical inspection, payment history, lease terms, etc.) and why you should have a reserve.

The previous owner still has all their stuff in there but they are not physically living there.
