However, in the wake of Covid, some notarizations were allowed online under strict rules which included recorded Zoom (or similar) sessions - but, those rules did not extend to authentic acts such as wills and real estate transactions (but some areas could still be valid as an act under private signature).

If so how did you go about verifying authenticity, I do not currently have the capacity to spend thousands for legal counsel.Thank You

A Gmail account is as secure as any email can be (if the account holder uses a strong unique password, and perhaps also two-factor authentication).  

So I called Land Ho, INC. back and left a message for them saying there is no record of Rocon of Bella Vista ever owning that property and questioning the authenticity of the deed. 

MFA then means Multi Factor Authentication - - combining multiple secretes, such as Password, Security Question, BIO input (eg finger print).

Im doing this as a listing agent, but I dont know, I somehow think that the letter still feels phony, not authentic enough,

But I would recommend finding a property manager who's also an agent so you get more authentic numbers for rent and expense expectations.

It's an hour long and the banter in there sounds very authentic.

From buyers to developers to builders to bankers, a successful real estate investor knows who they’re dealing with, what their best interests are, and how to communicate with them straightforwardly and authentically.

This is mainly because we hand- address our letters and use real stamps so it looks like authentic communication.
