If you live in the US, you can get parcel information from your local tax assessor's website, usually. Sometimes it's devoid of owner information. Such cases usually require going to a company like ReGrid or Corelogic to purchase the data.
I work for a company (onXmaps) which produces user-friendly maps of such information. You could use our app to create such a "rolodex" of your neighborhood, by annotating individual parcels with your neighbors' information.
