Who are the social media influencers in the real estate market that you could reach out to? There are plenty in the luxury sector and there are plenty in the purely real estate segment as well. Your job is to search for the right influencers on the right platforms that you could collaborate with.
If you have a small budget, this is a terrific way to market your real estate because you can get in front of hundreds of thousands or millions of prospective users without having to wait years and years to build up a big profile. However, be careful to vet the influencers well and ensure that their users are legitimate.
