Can text messages act as legal revision to vacation rental contract in New Jersey?

Most contracts will have what is known as an integration clause which says something to the effect of "this contract is the complete understanding of the agreement between the parties with regard to this matter" and essentially it prevents exactly what you're talking about. Much of the point of writing a contract is to get in one place all the things the sides expect from each other. Thus, making changes to it later should be done with something more than a text message. I understand this is frustrating in your case and perhaps a clever attorney could, upon inspecting the contract, find a way to get the result you want, but on the face of it, it seems the contract would trump.
