Hey @Daniel_M
That would be a bit hard to do in Webflow out of the box…
What your looking for is some sort of faceted search. Which doesn’t currently exist in Webflow.
You could look at some custom code solutions like explained in this post:
But apart from that, nothing out of the box. Sorry.
While Webflow is an amazing website design tool, sometimes there are other solutions better fit for purpose. I believe there are quite a lot of WordPress themes and plugins specifically designed for real estate websites and MLS data. Doing something like that may actually be simpler.
Hope that helps.
