In the following video, Motley Fool analysts Matt Koppenheffer and David Hanson discuss how record-high new-home prices are only one part of the loan-origination equation.

JPMorgan Chase (NYSE:JPM) and Wells Fargo (NYSE:WFC) are the two largest mortgage originators. Existing home refinance activity has been slowing compared with 2012, and margins are also falling. Will these trends continue?

Matt and David consider how mortgage banking fees generated by the sale of conforming new home loans to Fannie Mae and Freddie Mac help to offset low mortgage interest rates and thin interest-rate spreads.
