I’ve started looking at homes in the Portland area. I think the Estately is going to come in handy.
Estately is a real estate site allows people to search for properties by proximity to transit stops. It even allows prospective home buyers to limit their search to stops on certain transit lines.
This is another reason for transit agencies to publish GTFS and make it publicly available. Estately helps your prospective customers choose living arrangements that will make them regular customers.
You can read more details on the about transit proximity search page on Estately.com.
I discovered this site on the Headway wiki.
