If you cannot afford to buy today you might negotiate a ROFR in your lease where you have firsts rights to purchase if the owner every decides to sell the real estate.If you would own one space in a condo type for office or retail you have to be really careful with WHO is running the association because you will likely be a small percentage owner versus the overall spaces and have more limited control and input to what happens to the project as a whole.  

My scenario is a parent and child own a PA property, but live in another state. 

But you can't control how people live.This has ignited a question in me for @James Wise @Nathan G.

Often times I urge my younger clients and clients with short credit history to ask a parent, family member or very close friend to be added to their credit card as an authorized user!

I'm moving out of my parents' house in Dallas in the next month, and I want to live cheaply while I save for a down payment and look for the right property to invest in.

I contemplated the idea of just changing the design concept to have it be attached to the main home, but even in that scenario, the explicit CCR's against even renting one room seemed too controlling to be sane, considering that if this worked as we wanted, there were like 200 other nearly identical situations with lots with homes in that neighborhood that we would have just wanted to rinse and repeat that strategy.

Oregon has layers of LL/tenant law including statewide rent control, city ordinances, changes to rental screening and security deposits, etc.

The long way: Learn about Self Directed IRA rules, Checkbook Control IRAs, and Self Directed 401(k)s.

This is nothing more than the ultra liberal politicians that are currently in control bribing the voters to keep them in control.

OPM is a broad way of saying, you have none of your own money in a deal, but you own/control it and make profits from it.
