Unless Texas has very significant differences in the laws... you could very easily run into trouble.
While Real Estate Agents are permitted by law to work with certain forms of contracts for clients, only attorneys can do all forms of contracts.
The only exception is if you are one of the parties directly involved in the process... a buyer or seller. If so you could write anything up you both agreed to and no one would or could have issue.
As a loan officer... I would assume you would run afoul of both agents and lawyers and face charges of acting as a licensed agent and or attorney. All it takes is one phone call.
Also, If I were a real estate agent and knew you were providing self help real estate activities, I would not support your loan activity and would promote others also not to do so as, to me you would be violating federal laws preventing banks from being involved in residential real estate transactions.
In addition I would wish that the flies of ten thousand camels would visit upon you every moment of your life.... just kidding.... I think???
