Keep in mind their numbers are a bit skewed since they rely heavily on historical data.

I have a full-time day job so I'm not relying on real estate commissions for paying the bill, only to feed my personal real estate investing.

I would rely more on broker relationships to find the off market or narrowly marketed deals.

So, I rely on getting multiple bids to ensure that nobody is underbidding by a wide margin.  

A person with out a deep sense of personal integrity can usually be relied upon to carry out the letter of the contract most of the time which simply is not enough.

Solely relying on the 50% is risky.Great strategy!

We would be primarily relying on the rental income until we reach that age... good point, thanks!

There are still options, but in our experience, they were more expensive than the property insurance we hold on the two rental homes that my wife and I own in our own names.As others have mentioned, if you are planning to rely on the asset protection provided by an LLC, it is important to maintain the corporate formalities.  

Do not rely on the implicit assignability of a contract, because that won't release you from liability (there are now two responsible buyers -- eek!).

That's great, but I don't want to rely on anecdotal evidence.
