What is the easiest way to create a property listing website [on hold]

I’m hoping someone can steer me towards the right directions - I am trying to create a simple property listing website that will display properties for sale from multiple real estate agents. I did a quick research online and a possible quick way to to this is through WordPress which I understand will require less learning but I am not sure if there are any WP templates/add-ons that will allow importing of property feed from multiple sites. The other option I guess it to learn web development in order to create the portal.

Any advice on what would be the most efficient and quick way to achieve this will be greatly appreciated. Thanks
