I think you need to understand your potential user base more. Focus on a specific audience, one at a time. Your focus is too broad.

For the real estate use case, what is the specific problem they are solving with your tool? I can speculate that they want to track open houses in their area, and they don't want to open the social media app since it is designed to be a distracting time suck.

So where can you find people who work in real estate? Where do they discuss that specific problem? What other tools do people use instead? Are you competing with MLS sites, perhaps?

The 90 active but non-paying users likely have different use cases. You can try to learn those, although their willingness to pay hasn't been established yet.
