I understand Private Money may eliminate this hassle, but for the purposes of education let's assume HML is my only financing available.

Airbnb’s review system has worked wonders for their success and we think it is truly helpful when it is used for its purpose.

Many if not most commercial lenders require a SPE (single purpose entity) for a deal they're financing. 

While I’m still getting my head around this concept, the 3rd option is to cash out my retirement and place it into a Whole Life Insurance vehicle (infinite banking concept) to take loans against it for around 5% for real estate investments while the policy accuses/compounds over time, ie. 5 years (super simplistic for the purposes here).

Me at the time not knowing anything about any LLC's didn't even know there was options I just assumed the lawyer knew what he was doing.The purpose of the business will be potentially up to 50 buy and hold rentals.

The primary purpose of the inspection and this report is to evaluate foundation cracking highlighted in a recent home inspection report.

Once I changed my approach from letting  the other party be in control I took control in a very subliminal but purposeful manner.

These are typically disregarded entities for tax purposes as the LLC does not file it's own tax return and activities are reported on your own Sched E.  

And I have had several other appraisers that for estate purposes did work for me that ran basically 4 to 5 times what a bank pays for mortgage appraisal.
