When to create a single listing page to sell a house?

[Antonio Reybol, Jr.]

Hey there, I am trying to learn various ways to market a listing for sale. I aim to generate leads and spread awareness that a property is for sale. A few tactics that come to mind are: 

- creating a single listing page (landing page) that captures contact info 

- paid social ads that drive to the single listing page 

What's the perfect use case for a single listing page? Is it expensive to create? I am open to hearing your POV, experience, and any businesses that have created a single listing page for you. 

Thank you!
