@William Coet,as @Chris Seveney and @Kevin Sobilo mentioned, they very likely are either (A) already diversified, or (B) committed to real estate philosophically, or most likely (C) the tax advantages that come with owning and depreciating property, had done prior 1031 exchanges, etc. 

Underestimating the time commitment necessary for successFunny how the more complicated, higher risk, and more knowledge required to succeed in a Particular aspect of real estate the easier and simpler the gurus make it sound.

If you're considering upgrading your home with solar, think twice before making any commitments - it may not bring in the returns you're hoping for.

You should have this lined up and understand the options before you commit yourself to anything Especially if you are using hard money or any other then your own cash.

Brandon, commitment to learning is a good thing!  

I live about 3.5hr away but have a full time job, kids, and other commitments that make DIY challenging. 

While some use floating rate debt, for say, corporate unsecured lines of credit or capital commitment facilities, they also tend to use Swaps versus interest rate caps, and often times will build interest rate collars on their floating rate debt.  

Build relationships.The rest will work itself out if you are committed to meeting other investors and being an asset.

And it doesn't matter if its a cash transaction or a financed mortgage transaction.I'm not saying you are committing fraud.

Stay dedicated and committed to your real estate investments, keeping your goals in mind and being open to learning and adjusting to market changes.Good luck!
