Sometimes all I want is a good list. And for whatever reason, getting a precise rundown of the top mortgage originators by volume and market share is harder to come by than one may think. Consequently, when I came across this data I thought I'd post it for both my and your future reference.

What follows, in turn, are the five largest mortgage originators in the third quarter of 2012. As you can see, these lenders alone accounted for a staggering 53% of all mortgages in July, August, and September. That adds up to a lot of dough when you consider that roughly $475 billion in home loans were made during the three-month stretch.
