@Brandon Hawkins this is a big question. Unless you have a very big estate MAXIMUM protection may not be what you want due to the cost and complexity. The vast majority of RE Investors are served by simple appropriate insurance coverage or holding the real-estate in an LLC also with appropriate insurance coverage.
There are also multiple levels of LLCs owned by Wyoming companies or complex trusts but these come with lot of cost and complexity. Thy are also promoted heavily by guru type attorneys that greatly oversell the benefits.
What steps can a family take to ensure maximum protection of their assets when entering the real estate investment market?
Appropriate protections might include Umbrella Insurance, Equity Stripping (the legal kind), having a loan on a property (not having it being free & clear), Using the property's street address as the LLC name instead of using your own name, changing the password on your accounts every 90 days and using 10 character passwords and two point authentication. Not having online access at all to your banking accounts, not clicking on links you don't know, using a mailbox address instead of your home address, you know, the usual stuff.
Nothing is guaranteed but it will slow down the bad guys.
