All decisions of the human being are taken emotionally, I insist on it, all of them.
Definitely we will need data: cost, delivery schedule, quality of the house, financing, signal to the booking, area where it is located, etc.
However, all these data will have no relevance to the decision without first provoking something fundamental in our interlocutor: desire. That reaction difficult to measure that drives us forward. It is essential that, from the beginning, the real estate developer revitalizes that reaction. And that, I assure you, It is impossible to get with data, it is achieved with images or, even better, with a film of your project.
If you are able to thrill that person interested in your flat, you will have 75% of the sale made.
But if he is not thrill, you have nothing.
