I have focused most of my time and attention on residential units, but something has come up in my family and was hoping someone could provide some insight.Here's the scenario:Say you own 1/3rd of a commercial apartment with your two siblings each owning another 3rd.

If I were you I'd be looking for somewhere else to hang my license as this broker is most likely going to terminate you as soon as this fiasco is over, don't make threats to the next person, and focus on selling more deals.  

We want to be unique enough that  visitors will pick our property on how beautiful or cool it is rather than it's the least expensive.

There are numerous meet ups both focusing on areas North and South.

My focus is buy and hold with cash flow being the priority, and a mix of cash flow with appreciation being a close second depending on market.

Then there will be a few odd ducks that need lots of repairs or where there is a big 2nd mortgage to negotiate down and you'll be first in line to buy these.I actually like this model better than what investors used to do (negotiating directly with the bank) because it's a lot less work and we as investors can focus on the other parts of the business.

Seems like you have another job, so focus on buying quality real estate and hold it long term. 

Since my focus now is retirement and cash flow - leaning towards all cash purchases but totally understand both pros and cons.

We are partnering with a long time friend of mine and will be focusing on small multi-family properties to buy and hold. 

Turnkey is a long-term investment focused on cash flow, so you let your tenants pay off your loan, you pocket the net income for a while, and then eventually the property is paid off and your cash flow balloons, usually around the time you really need it for retirement.
