I love asset protection structure that utilize land trusts, series LLC's, agent and living revocable trusts, when needed DST's. 

The seller already signed consent of dual agency months ago when they listed the house. 

https://www.rentspree.com/blog...Landlords and property managers are approved by FCRA regulations to legally review a tenant’s credit report (with consent) for the sole intention of determining an applicant’s qualification to rent.

To start, I am looking to structure my investing by creating an Revocable living trust with an LLC or multiple LLC's within it where appropriate.

Therefore, terminating a tenancy by the entirety requires the consent of both parties.

First off he may not be able to convey title without the other owners consent it depends on how the ownership is structured. 

All of the properties are held in a revocable trust that is in both of their names (meaning both the deceased spouse and living spouse).

This would protect your interest in the property.What your real concern is you need to be SURE of the  language of the Trust if it can be amended, is it a revocable trust or a irrevocable trust, who is POA for trust grantor, and what powers the POA has.

Furthermore he said the LLC should be controlled by a Revocable Living Trust, with myself as the controlling agent of that trust.

In law, there are aspects of specific and implied warranties, representations, guarantees, agency and consent, passing out written materials can cross lines if you are not familiar with these legal matters, it's somplace investors shouldn't go.
