Great Lakes Credit Union backs Duome to tackle Chicago's housing affordability gap
What's the deal? Great Lakes Credit UnionDealroom has a profile for this one. Try Dealroom → (GLCU) has made a growth equity investment in DuomeDealroom has a profile for this one. Try Dealroom →, a credit union service organization (CUSO) that co-invests alongside homebuyers. The deal, made through GLCU Holdings, is the first step toward bringing Duome to members across the greater Chicago region.
What does Duome do? It co-invests directly in a home alongside a qualified buyer, shrinking the mortgage to a size the household's income can comfortably support. The buyer lives in the home, owns it, and builds equity from day one.
Why now? Chicago's median metro home price hit $401,000 this summer, up nearly 7% in a year, as limited inventory widens the gap between incomes and prices. A 2026 Chicago Community Trust analysis found fewer than one in seven credit-ready renters could afford a home above $200,000.
Who's behind it? GLCU, founded in 1938 to serve civil servants at Naval Station Great Lakes, holds more than $1.4 billion in assets and serves over 105,000 members. Its GLCU Foundation offers homebuyer counseling and financial education.
What's the endgame? Duome and GLCU will now prepare the program for members, including education, lending coordination, and platform integration. Because Duome is a CUSO, partner credit unions originate the mortgage and keep the member relationship.
"We know firsthand how many members can make a monthly payment but can't qualify for the mortgage today's prices require," said Michael Abraham, chief executive officer of GLCU Holdings. "Duome bridges that gap."
The signal: The investment reflects a broader credit-union push to use service organizations and impact capital to expand mortgage access. Duome, which won the 2026 NACUSO Next Big Idea competition and already backed by One Washington FinancialDealroom has a profile for this one. Try Dealroom →, is becoming a local test of an alternative financing model — though its scale is hard to judge without disclosed terms.
