A realtor not assisting is intended to mean not filling it out for the individual but it's acceptable to help them with issues like the one's you have pointed out. Since your agent has seen the property and has the ability to visit it, they would be the best source for accurate information.
You are right, some people may have different views of the same questions.
You are right realtors should not assist you with the form.
You might ask a friend, family member, or neighbor to assist you.
