Unless a bona-fide income source is willing to guarantee payment through the term on the lease, and guarantee payment for any damages caused by the tenant - their agreements with the tenant are irrelevant to me, and I'm forced to make my own conclusions about the risk of that income source terminating or damage caused by the tenant's negligence.Furthermore, I think that income source (in many but not all cases) is a fairly good proxy for the care rental property in their possession will receive.

Considering it's been in foreclosure since 2016, I'm confident "Principle Balance" and "Payoff Amount" are worlds apart.Also, while 90 days is the norm after the foreclosure before you have to move out, you would not be considered a bona fide tenant considering your rent would be below market value.

I would bet that most states, when confronted with a factual scenario where a money judgment lien is perfected in the gap (after notices to junior lien holders are sent by the foreclosing lender, but prior to the auction sale) hold that the judgment lien is extinguished as to a bona fide purchaser regardless of whether actual notice of the sale was received.

At that point, however, Vesta, or Investa might be considered a bona fide purchaser after the fact of what they believed was a valid lien.  

Here's the language:"Grantee herein shall be prohibited from conveying captioned property to a bona-fide purchaser for value for a sales price of greater than 120% of the purchase price for a period of 3 months from the date of this deed.

The term does not include --(A) any officer or employee of a creditor while, in the name of the creditor, collecting debts for such creditor;(B) any person while acting as a debt collector for another person, both of whom are related by common ownership or affiliated by corporate control, if the person acting as a debt collector does so only for persons to whom it is so related or affiliated and if the principal business of such person is not the collection of debts;(C) any officer or employee of the United States or any State to the extent that collecting or attempting to collect any debt is in the performance of his official duties;(D) any person while serving or attempting to serve legal process on any other person in connection with the judicial enforcement of any debt;(E) any nonprofit organization which, at the request of consumers, performs bona fide consumer credit counseling and assists consumers in the liquidation of their debts by receiving payments from such consumers and distributing such amounts to creditors; and(F) any person collecting or attempting to collect any debt owed or due or asserted to be owed or due another to the extent such activity (i) is incidental to a bona fide fiduciary obligation or a bona fide escrow arrangement; (ii) concerns a debt which was originated by such person; (iii) concerns a debt which was not in default at the time it was obtained by such person; or (iv) concerns a debt obtained by such person as a secured party in a commercial credit transaction involving the creditor.(7) The term "location information" means a consumer's place of abode and his telephone number at such place, or his place of employment.(8) The term "State" means any State, territory, or possession of the United States, the District of Columbia, the Commonwealth of Puerto Rico, or any political subdivision of any of the foregoing.15 USC 1692b

Do you have a bona fide lease agreement with the former owner?

That way, I know I'm mailing to a bona fide note holder.

You get people to sign that contract by presenting yourself as a bona fide buyer.If that is what you mean by "business details of how you conduct business" then you should find a more honorable profession. 

on line auctions usually accept a pre approval letter from a bona fide lender.. along with your cash in bank should be no issue.
