here are plenty of free ways to promote your property. Take advantage of the most common sites and test out some new ones every once in a while. Since there are so many different platforms for finding apartments, posting your listings in more places can’t hurt.
As you’re showing your properties, ask people how they found your rentals. Over time, you’ll not only be able to track where most of your traffic is coming from–you’ll get a sense of which methods are a waste of time, and which newer platforms are gaining traction.
