Is Borrower Authorization form needs to be notarized (Texas)?

NA NA i have been managing rentals in some rough neighborhoods in chicago, and never wanted to take the chance on any type of confrontation with an angry tenant, so i have always mailed the 5 day notices (regular mail even) even though the notarization claims that it was delivered in person.  

If not are there any other options for us?

We met yesterday, armed with all the necessary paperwork and a notary, and walked out there with for executed and notarized deeds.

This might be a different scenario, but the thought is the same, we as a construction company can "assign" or "authorize" anyone to sign, transact contracts, just like you can when you pull permits, anyone can do it if you authorize them, you must execute a board resolution naming the individual and what he can do, his limits, etc, then it must be notarized and stamped, signed by secretary and president.

A letter can not be recorded as evidence that the lien has been released.You need a certificate of satisfaction, a document that that has been notarized, which affirms that the lien has been satisfied and is released. 

Once this paperwork is notarize I have myself a good deal in my hand

If not, are you ethically ok with this and can it impact your RE license?  

They keep stacks of deposit slips for my people to pay rent, notarize things and ask how they can serve me better.
