We had an interesting pitch come in at work that I looked into a couple of techniques. It was to build an interactive map similar to airBnBs approach. The plan was to use geojson for the info such as location and features of the property. Then using leaflet I would plot the locations and pulling in the data from the json also add pictures and some information. There is also a addon for http://leafletjs.com/ called fuse which allows you to search the json.
Here is the working prototype. Styles are not existent but I produced it for proof of concept.
