This is more of a chart / map (chap or mart?), showing the origin points for mortgages during the decade leading up to the housing boom. It’s a national map, but I zoomed in on the Twin Cities to take this snapshot.
The map also includes race data, which is interesting too. Click here for the full map.
Originations also include refis… the most recent originations boom that just died down over the past year was mostly refis.
