I think someone who is younger, or female (like it or not) might have a harder time investing in undesirable areas unless they had some muscle behind them.

(Something I picked up from the book Secrets of the Millionaire mind by T.Harv Ecker) I made this declaration to my wife and she said she'll support me in accomplishing this.

I will sometimes look into the will to make sure that the applicant is declared as executor. 

It is the formal point when papers are filed publicly declaring that a default has taken place.

I'm no expert, but my loans have the following info: "I/We, the undersigned, hereby declare that I/We have never in the past and do not currently reside on, us, or in any manner claim as a homestead, either business or residence, and that I/We have no present intent to occupy in the future, use or claim in the future, either as a businesses or a residence homestead, the tract or parcel of land now being offered as security for a loan the lender identified below......it lists the county, the legal description etc blah, blah, blah".

If you require "partner's approval" in order to perform, any Judge could declare that you do not have the legal authority to execute a contract.

Oh, I've also declared around $80,000 in losses on my tax returns, so that's around $20,000 in tax refunds. 

I would declare the tenancy and left over personal belongings abandoned according to your state law and get it re-rented to a better tenant!

However to answer the question you posed, Landlords have been stripped of our constitutional due process rights, and there is no legal way around a Governor's emergency declaration.
