An analysis of 2014 mortgage data revealed 10 metropolitan areas where credit unions originated more than 30% of total mortgage loans.

The Washington-based credit union consulting firm Callahan & Associates conducted the analysis of mortgage information, which was collected under the Home Mortgage Disclosure Act and made public in September 2015.

Credit unions in the Waterloo and Cedar Rapids, Iowa area originated the largest share of their area's mortgages, writing 44% of the metropolitan statistical area's home loans in 2014, according to the firm.

The $2.8 billion Veridian Credit Union of Waterloo, Iowa led in that market with a 24.35% market share. The $3.1 billion University of Iowa Community Credit Union of North Liberty, Iowa took 14.6%, Callahan said.

Callahan reported credit unions from the following nine other local areas also originated more than 30% of the home loans in their areas:

La Cross, Wis.-Minn. – 35.5%

Pocatello, Idaho – 36.3%

Iowa City, Iowa – 36.1%

Cedar Rapids, Iowa – 35.5%

Appleton, Wis. – 32.1%

Saginaw-Saginaw Township North, Mich. – 31.3%

Utica-Rome N.Y. – 30.3%

Anchorage, Alaska – 30.2%

Cumberland, Md.-W.Va. – 30.2%

Callahan's analysis determined credit unions increased their overall market share by 0.3% nationally in 2014, despite an overall mortgage origination drop compared to 2013.
