It's a matter of finding the one where the weaknesses are in areas that aren't relevant to your needs and/or don't aggravate your personal pet peeves. 

More glasses, plates, bowels etc.You need bigger pans as well.

And your communications need to be very wise, meaning they can't come across the wrong way regarding tone, even when you're aggravated.

.: Quote from @JD Martin: I can't possibly imagine what kind of townhouse could be worth all of that aggravation and cost.

If you are going to aggravate me, I'm going to get paid for it or you're going to move. 

To scale successfully you have to get past the point where your newly increased expenditures exceed your increased revenue; past the point where your ROI allows you to “break even” on your investment, and past the point where the ROI is worth the increased risk, the increased aggravation, time, and “lifestyle” change, and past the point where you can step back from “operations” and concentrate on management.  

BUT…So has his aggravation, time commitment, and risk.   

But, here’s a situation in which having my properties in SEPARATE series of an LLC saved me enormous time, aggravation and money.in 2012 I purchased 5 individual high rise condos in different buildings in Phoenix, AZ.  

It's so aggravating.

I would be aggravated too, but it seems like one of those things where the effort to get juice from a stone wouldn't be worth it.
