I will send you a copy of the agreements that I have and they are legally binding. 

But, this might not exist prior to close.Although I'm just starting out and don't know too much, I would think having your tenants sign estoppel certs during escrow (as @Aaron K. suggested, to which I just learned) is necessary so as to avoid any unwarranted legal disputes.

Maybe just say you will pursue legal action if the situation isn't immediately addressed.

@Marcus GriffinTypically as part of a modification the bank will have a “shock package” which includes information and forms to be completed by the borrowerOn those forms there are questions like will they or do they occupy the property, there income, do they plan on keeping th home.This is equivalent to lying on a bank application which is most likely considered fraud Not providing legal advice but this is definitely a very slippery slope you are getting involved in.

Is it better to respond legally or simply to fill out the form.
