Massachusetts’ fastest-growing credit unions by residential real estate lending

The 25 fastest-growing credit unions in Massachusetts for real estate lending held approximately $16 billion in total combined residential real estate loans as of March 31, 2025, marking a 7.52% increase over what was reported in the year-earlier period. The online version of this ranking expands beyond what appears in print; another 44 credit unions are included in our digital rankings, in addition to the 20 featured in this week’s print edition. This week’s List is part of a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ’s footprint — this year alone. Information on The List was obtained from the National Credit Union Administration and could not be independently verified by the Boston Business Journal. Rankings were determined by year-over-year dollar value change in residential real estate loan volume in the period analyzed. In case of ties, credit unions are listed alphabetically. Unlike the banks version of this List, commercial real estate loans are not included here, as the NCUA classifies them under its broader commercial lending category. To qualify for this List, credit unions are required to have a residential real estate lending balance at the end of the first quarter. Only institutions headquartered in Massachusetts are included.
