Do you explain what property right are and what property rights come with their deed?
Do you tell them they are signing away their property rights to the association?
I have a license also and found the industry loaded with misdirection and deliberate omissions to CYA the agent.
I'm no genius, but I have a business degree, some graduate work in economics, a few law courses, a real estate broker license (8 college courses) and passed the broker exam.
I know the history of laws, which mainly dealt with property. We don't have "absolute" property rights in many cases. Your neighbor may have a "right" to cross your property, for example to get water to his property.
Each region is unique. My father was a builder since my earliest memories, and I was a curious kid. He taught me a lot, before I ever thought of getting a license after my corporate career.
So yes, I do school people to the extent their curiosity asks me for. But I do not have an obligation to overdo it. I have an obligation to inform him of what he should think about.
I cannot build above 3 stories, because of the city building codes. I am NOT in an association. That illustrates for you the FACT that property rights are NOT absolute.
I remember decades back that Houston had few zoning restrictions. You could build an apartment next to a factory next to an amusement park next to a hospital etc.
Somebody from Texas is better qualified to talk about those Houston property rights.
I would advise a client that even in the most remote regions of the USA, that much due diligence is necessary to determine exactly what are the restrictions on property rights, usages, etc.
