It's easier and better protection.

If I own my properties via an investment holding company that owns subsidiaries that take title to my properties can I do a property cash out refinance and pay the proceeds to the holding company tax free to buy more properties that are fully owned by the holding company to protect each of my properties from each other.Would an LLC or Corporation structure be preferred for this to work?

If it happens to be a friend or relative who believes in your and knows you, then you might get a great interest rate, but you still need to protect them with a mortgage and/or a deed of trust AND closed at a title company or Atty office.

Your personal assets are protected from any issues that could arise from investing in real estate. 

A Payroll Protection Plan Loan is an SBA Loan for existing businesses.

What type of legal entity would be best for us all to be protected?

I know that it's better to set an LLC for every rental property, considering that the main purpose is asset protection, but I also read that you could have more than one under the same LLC as long as they have low equity.

@Lee SyndergaardFirst I would make a list of all my assets and the way they are titled (bank accounts, savings, brokerage, retirements account, properties) and their value.I would bring also copy of will, living trust, advanced directive, and other documents regarding estate planning.Then I would also have a simple financial statement of the different investment properties and bring a copy of the lease agreement and insurance policy.The different topics that you would probably want to discuss with your attorney would be:Your estate planning,Your asset protection,Your real estate operation in regard to tenant selection, lease agreement, tenant eviction, security deposit holding and return, advertising regulation, licensing requirement, insurance.

Let’s say, yesterday me & my motivated seller agreed on a deal, Today, I file affidavit as protection of course, Howeva b4 my 30days up, motivated seller cancels no apparent reason, ThenA week later, Title Company calls me, to release the cloud & I basically negotiate & i get payed to not buy a house, After all that settles, wat do I say to the cash buyer?

Wyoming has more protections. best of luck to you.
