Thanks @Jim Goebel,
The St Germain Act excludes transfers to an Inter Vivos Trust (estate planning tool) from the Due on Sale Clause. https://en.wikipedia.org/wiki/Garn%E2%80%93St._Germain_Depository_Institutions_Act
Privacy has many benefits, and most of them won't be realized until an investor needs them - but by that time it is not available. This blog begins to touch on some of the benefits and planning to achieve privacy: https://www.biggerpockets.com/blog/anonymity-asset-protection-dummies-avoid-law-suits
The LLC or trust, even if not private, helps to limit liability to the properties in the entity. I did a review of properties owned under individual names in a resource we subscribe to, and was surprised to see investors holding large numbers of properties in their personal name (or their spouse). The danger is that if a judgement is made, Investors need to make seriously bad decisions related to their investments to free up equity to pay the judgement. Insurance generally doesn't cover negligence.
I recommend new investors get informed and understand that real estate investing is a business. Over time, those decisions will protect the equity that is being developed.
