Thoughts on Map Marker Algorithms?

We're a property related platform, and we're building a map to display property listings to potential tenants. Many of our properties are close together, but clustering is not a great UX. Taking a lot from AirBnB, we're struggling to find a simple way to display listings intelligently on the map - avoiding typical clustering in favour of something more interesting.

Any practical advice on creating a great map UX with a lot of markers/pins?

PS: The platform isn't data centric, so showing all pins isn't necessary for the purpose - a better UI/UX is more important(?).
