Avoid the Hidden Traps: The Due Diligence Strategy Every Credit Union Needs


Smarter Decisions Start with Smarter Files

For credit unions pursuing growth through whole loan or bulk purchases, mortgages or consumer loans, the opportunity is compelling: improved net interest margins, diversified asset mix, and expanded member solutions.  However, growth comes with inherent risk, especially when due diligence isn't executed properly or quickly enough. At StoneHill, A Sourcepoint Company, we empower credit unions to seize these opportunities with confidence, by delivering industry-leading due diligence that moves at market speed.

Why Due Diligence Is Mission-Critical Now

The secondary market has changed. It’s faster, more complex, and encompasses a broader range of products, from conventional to non-QM, seconds, HELOCs, and reverse mortgages. Today’s credit union buyers need comprehensive analysis that goes far beyond surface-level reviews. A credit union buyer must rapidly validate:

  • Data accuracy across all loan file documents including 1003s, credit reports, income documentation, title records, collateral valuations, and compliance documents – LE/CD
  • Regulatory compliance at Federal, State, Investor, and GSE level
  • Guideline adherence across all files reviewed in the trade to ensure the credit union is putting quality loans in line with the organization’s risk strategy on the books
  • Documented defects that can impact pricing, loan integrity, and potentially diminish portfolio value

In this environment, due diligence has evolved from an operational necessity to a mission-critical strategic function.
