Walkscore is an easy way to inform tenants on nearby public transportation options
You can type in the address of any building you are leasing or selling and it automatically calculates the distance to public transportation and provides a numerical score to compare between properties. Best of all, it's a public facing website so you can email landlords or prospective buyers the link and it's free. 

This score is listed for each property on the MLS, but you can also use their website directly. [walkscore.com](http://www.walkscore.com)
