Mapping has currently been used in MLS systems to show the location of properties, and occasionally through data layers and other interactivity, to show information about the property and its surrounding areas. However, mapping has a lot more promise than it has been used for currently.

Mapping can be a great tool for communicating agent knowledge about neighborhoods and communities. In some systems there is currently a way to turn on specific categories of "points of interest" (POI), but does it really help a gourmet seeking a home in a high-end community to show them every McDonalds and Burger King in a two mile radius? Not at all – rather, if the agent shows the consumer that map, it demonstrates that the agent doesn't understand their client. It definitely doesn't show the client that the agent is the neighborhood expert and can help interpret the plethora of information available. So, one key feature for turning maps into a useful tool to build a bridge between agents and consumers is allowing the agent to customize the map, edit the content shown to the consumer, and add user generated mapping content.

Illustrated below, an agent is showing the listings desired by the consumer alongside some specific restaurant and shopping options. You can see that in the Bistro detail shown, customized text and additional information has been entered by the agent, showing the client that they know the neighborhood, and have been to this restaurant before.

For example, if the prospective buyer had a child that studied karate, the agent could have added the nearby dojo to the map, along with the commentary "I think Suzy will really like the karate instructor at this dojo." Or, if the buyers had children in elementary school, the agents could add rich, relevant and even personalized content about the local schools as well.

The key to successful user generated mapping content is for it to be very easy to add the content. It must be easy for agents to add new custom points of interest, pre-fill basic information from existing data sources, and create content libraries that they can leverage to create custom maps for consumers with a minimum of entry or re-entry.   Getting these workflows right is critical to feature adoption.

Another area of mapping that could be greatly enhanced is to use mapping layers to show demographics. In many surveys Clareity has performed, agents seem very skittish about this – especially when it comes to showing crime maps. Some agents have legitimate reasons for skittishness – fear of being accused of steering or other violation of fair housing laws are valid concerns – but it's up to real estate professionals to provide the consumer the information they want and need to make a buying decision. If consumers want it and the real estate practitioner won't provide it, they'll get it elsewhere and the value perception of the REALTOR® will continue to decrease. As former NAR president Billy Chee said to me back in 2002, "The consumer is the lion coming over the hill."

Mapping also has great power to display complex information in a way that's very easy for people to interpret. One of my favorite visualizations is the 'weather map' or 'heat map'. Consumers can readily obtain heat maps from Trulia, Zillow, CyberHomes, and others, but not from their agents. Why is this? While some MLS systems already have heat maps to show days on market or price per square foot, it's easy to imagine other heat maps with even more useful information.  The example below shows what areas are 'hot' or 'cold' for investors by showing appreciation over time. Such maps could also show vacancy and absorption or even percentage differences between initial asking price and final asking price or sale price, or even show shading representing the percentage of properties in foreclosure.

I've shown 'heat' two ways on the map above – with colored icons and with color shading. It's probably only necessary to use one method or the other. Icons will certainly be technically easier to implement than shading, though at a wider zoom level area shading may make more sense.
